Using the KX-G7100/7101 - 1

Using The KX-G7100/ 7101

INTRODUCTIONThere are two ways to communicate with the Panasonic KX-G7100/7101 Subscriber Communicator(SC). The SC can be connected to a PC or DTE via its built-in RS-232 serial port, or can be accessedindirectly through the ORBCOMM system (remote PC/DTE to satellite to SC, referred to as "HOST"from here on in).

Further, the KX-G7100/7101 is configured for operation with two command sets: the defaultORBCOMM command set, and the Panasonic command set.

The ORBCOMM Command SetThe ORBCOMM command set uses two serial port interface modes for communication: the primaryProtocol mode, and Byte mode .

Protocol modeIn Protocol mode, the communication between SC and DTE is based in the Serial InterfaceSpecification as prepared by ORBCOMM. The DTE can send and receive messages, reports,commands and "GlobalGrams", as well as obtain time-of-day and position estimates.

This is the SC's default mode of operation. If desired, the default can be changed to Byte Mode usingKXS31 (Operation Mode).

Byte modeByte mode is used primarily for direct-connection communication between the SC and PC/DTE. Inthis mode, data bytes are generated without header, length field, or checksum information, allowing amore efficient transfer of large messages. However, the transfers are less robust due to the lack ofacknowledgements and checksums.

Configuring the SC to identify Byte mode data can be done by configuring these Panasoniccommands: KXS32 (Byte Mode Trigger), KXS33 (Byte Mode Timeout), KXS34 (Byte Mode Length),KXS35 (Byte Mode TX SOM/EOM, RX SOM/EOM).


The Panasonic Command SetThe Panasonic command set is divided into four subsets, each having its own section in this manual:

• Transmission Commands

• Tracking Function Commands

• Setup Commands

• Special Commands

Accessing the Panasonic Command SetThe KX-G7100/7101 uses an on-board command interpreter, allowing you to see immediate results ofchanges made to any command parameters on the PC/DTE screen. If using a PC, you must havecommunication software (i.e. HyperTerminal or equivalent, set at 4800/8/None/1, Flow Control OFF)and an RS-232 serial (modem) cable for connecting the SC to the PC. To access the SC and use thePanasonic commands, enter the following:

CTRL + K X O R B(Hold the CONTROL key down while typing the ‘K X O R B’ characters.)The PC/DTE will acknowledge with the SC's serial number and the right chevron ( > ) commandprompt.

To exit the Panasonic command set, enter CTRL + Q.If no command is entered after 5 minutes, the SC will default back to the ORBCOMM command set.

Inputting the Panasonic CommandsAll Panasonic commands are input in UPPER CASE. Commands begin with the letters ‘KX’ and endwith <Enter> or equivalent (<Return>, <CR>, <CR><LF>). Command parameters or variables areseparated by a comma ( , ). These commands are available in both PC/DTE and HOST operation.

Sending CommandsFrom the PC or DTE:• Change to command mode (type <CTRL> KXORB).

• Send only ONE command at a time.

• Wait for the “>” prompt from the SC before sending additional commands.

From the HOST (remote):

• Message must be placed in the email message body (not in the subject line).

• The first character of message must be “$”.

• The maximum size of the message is 180 characters.

• After each command, press the <Enter> or <Return> key. On some DTEs, it may be necessary touse <CR>, <LF>, or both <CR> and <LF>. (<CR> is 0x0d, and <LF> is 0x0a.)

Example: To set the Acknowledgement Level (KXS06) and Transmission mode (KXA05), type:

$KXS06=1 <Return>KXA05=0,1,2,3 <Return>


Remote Configuration Password

To prevent tampering and assure security, a remote configuration password can be assigned usingKXS71 (Remote Configuration Password). The password must be appended to the appropriateSetup, Transmission or Tracking command in order to allow remote configuration changes.

By default, KXS71 is set to "0000", meaning no password is active and therefore not needed in themessage body. Assigning a value to KXS71 activates the password and mandates its use in themessage. Furthermore, assigning a value to KXS71 also serves to activate an inherent, secondarypassword: The last four digits of the SC's serial number. Either can be used when KXS71 is set.

Example: To configure KXS06 and KXA05 when KXS71=AZ90.

$KXS06=1 <Return>KXA05=0,1,2,3 <Return>PW=AZ90 <Return>

Another use of the password feature is Group Configuration. To configure a group of SCs, set KXS71to the same value on each SC in the group.

Command Response MessageAfter a KX command is sent, an ACK or NACK response message is received from the SC.

<ACK> MessageWhen a command has been sent successfully, the SC responds by echoing the message that wassent.

For example, the command “ KXA06=2,1 <Return>” would be followed by “ KXA06 = 2,1.”

<NACK> MessageWhen a command is unsuccessful, one of the following error messages will be received.

• ERR0 –Parameter error (the parameter is beyond the minimum or maximum permissiblevalue), or Command not defined (command does not exist).

• ERR1 – Exclusive control error (two or more settings conflict).• ERR2 – Response message not created. During a remote configuration session, If the

receive buffer is full, the SC will send this error message to the HOST.

Except in the case of ERR2, command responses from a remote configuration session are not echoedback to the PC/DTE. If confirmation via email is desired, KXS72 (Echo Remote Command Response)can be set to see the echoed responses from each entered command.

Please note that ONLY the default O/R recipient set by KXS05 can receive the echoed responses.

Transmission Commands - 5

Transmission Commands

Using the Transmission Commands

The Panasonic Transmission Commands can be thought of as macro commands. The TransmissionCommand set is designed to allow a user to quickly and easily design and implement an application.

Restrictions on Selection

KXA01 - KXA04 commands:Only one command can be active at a given time.

Example: If KXA01 is active and the user inputs the KXA02 command, the KXA01 command will becanceled.

KXA05 and KXA06 commands:KXA05 can be active at the same time other commands are active. KXA06 can always be used,regardless of the transmission commands typed in.


Automatic Power-Down(See flowchart in Appendix F for more detail)

KXA01 - KXA03 commands:When the KXA01, KXA02 or KXA03 commands are entered, the Power Down mode will beautomatically activated (KXS37=1, Power Down mode - On). At the start of the specified function, theSC will power on automatically and stay awake for a specified interval, in order to send data.

To prevent the SC from sleeping while using KXA01, KXA02 or KXA03, disablethe automatic Power Down mode. Configure set-up command KXS37=0 (PowerDown Mode - Off).

KXA04 or KXA05 commands:

KXA04 or KXA05 will automatically disable the Power Down mode (KXS37=0 Power Down Mode -Off)

To power off automatically when either KXA04 or KXA05 is active, use KXS37=1(Power Down Mode - On), or use the remote control lines.

SC Power ON/OFF OperationFor the SC to power down automatically, the following conditions must be met:

SC has its latitude and longitude (KXS23),

SC has satellites’ orbital elements,

Age of orbital elements is less than KXS22.

When the SC does not have the satellites’ orbital elements, the SC will repeat the Power On-Off cycleuntil the orbital data is acquired.

5 min 5 min 5 min.

Power On Power Down Power On Power Down


Wake-Up Time Duration: KXA01-03Wake-up time is the time set by the KXA command or the time a is satellite acquired when SC hasmessages in the inbound queue. During the wake-up interval, the SC will power on and begin:

• Creating data for transmission

• Transmitting data

• Calculating the next start time

The SC will transmit immediately after the data is created.

When using KXA01, KXA02 and KXA03, the SC will wake-up for the minimum period shown in Table 1below. This period is a function of the type of data to be transmitted.

When a Satellite is Not AcquiredIn the event that a satellite is not acquired in the first pass, transmission will occur upon the acquisitionof the next satellite. Under these circumstances, the wake-up interval will be ten minutes.

If the SC cannot create the data during the wake-time interval, the SC will send the following messageto HOST:

Message Type <Error Message>POSITION NO POSITION DATA, (Time Stamp) <Return>Poll to DTE NO DATA FROM DTE, (Time Stamp) <Return>

10 minutes


Power-Down Interval: KXA03Using KXA03 will cause the SC to sleep until the next satellite is acquired. Power consumption can befurther reduced by selecting a power-down interval that will cause the SC to sleep through severalsatellite passes. After the power-down interval has expired, the SC will wake-up on the next satellitepass.

For example, when interval timer is set to sixty (KXA03=60,x,x), the SC will sleep at least for 60minutes after it sends the data and powers down. If no satellite is acquired, the SC will continue tosleep until the next satellite pass.

Tracking Commands - 19

Tracking Commands

COMMAND NAMESKXB01 = Wake up at a specified time, wait for a designated event, perform assigned functions,and transmit.

KXB02 = Wake up for one specified interval, start observation of event, perform assignedfunctions, and transmit when event meets the assigned condition.

KXB03 = Wake up upon satellite arrival, start observation of event, perform assigned functions,and transmit.

COMMAND DESCRIPTION

The Tracking Commands, also known as KXB commands, are a superset of the TransmissionCommands and are unique to the KX-G7100/7101 series SCs. These commands reduce powerconsumption and have increased functionality. Each of the Tracking Commands will conditionallyperform a specified function and transmit upon satellite availability. To conserve power, thecommunicator will enter sleep mode between satellite passes.

Conditions are sampled during a period called the Observation Period.


Using the Tracking Commands

RestrictionsTracking Commands CANNOT be used in conjunction with other Tracking Commands. For example: KXB02CANNOT be enabled when KXB01 is active.

In addition, the Tracking Commands CANNOT be used in conjunction with the Transmission CommandsKXA01 ~ KXA04.

Tracking Command FunctionsSeven functions are available when using Tracking Commands. Functions may be used individually ortogether. If required, all seven functions may be used in any of the Tracking Commands. The sevenfunctions are as follows:

1. Current Position Data2. Current Digital I/O3. Fixed Message4. Poll NCC5. Poll DTE6. Run User Application7. Current Analog Port

(For more information on the Tracking Command Functions, see Appendix D: Transmission DataFormat.)

Tracking Command ConditionsFour basic conditions are available for use with the Tracking Commands.

• Distance• Speed• Area In• Area Out

Each condition is configured using the appropriate Set-up command.

Distance• Executes GPS position calculation at KXB command power on.• When the SC moves the appointed distance from initial location to current position, the SC judges (by

KXS56 - Distance Select) that a Distance Event has occurred.• Initial position is first position that results when the SC executes the KXB command with condition B.

When the SC detects a distance event, the SC always updates the location as reference location .


KXS56

Note: mark indicates event occurrence.

Speed• Executes the GPS position calculation at KXB command power on.• When the SC’s speed exceeds the appointed speed, the SC judges (by KXS58 - Speed Select) that a

Speed Event has occurred.

Velocity threshold KXS58

Sampling rate is approximately once every one second, and a minimum of 5 (five) samples are required todetermine that an event has occurred.

Area In• Executes GPS position calculation at KXB command power on.• When the SC enters the assigned area, the SC judges (by KXS57 - Area Select) that an Area In event

has occurred.

KXS57

×Radius

LAT/ LON

• The SC must be in the area for at least five intervals per the one-second measurement interval.


Area Out• Executes GPS position calculation at KXB command power on timing.• When the SC exits from the area assigned, the SC judges (by KXS57) that an Area Out event has

occurred.

KXS57

× Radius

LAT/ LON

• The SC must be in the area for at least five intervals per the one-second measurement interval.

Logical AND and OR functionsConditions may be combined using logical AND and OR functions. For example:

• Distance AND Speed• Distance OR Speed

When using a logical OR statement, at least one of the two conditions must occur for the event tobe satisfied. When using a logical AND statement, both conditions must occur for the event to besatisfied.

Inverse conditionsThe following Inverse conditions are available:

• Speed Not• Distance Not• Area In Not• Area Out Not

Note: A (NOT) event or a combination with (NOT) event occurrence is determined at the detection time setby KXS79 (Event Timer).

No ConditionWhen conditions are not required, the "No Condition" option may be selected. In these instances,the KXB (Tracking) Commands will function in the same manner as the KXA (Transmission)Commands


Detection Event

The TX event can be selected from the following table of Event Condition Codes.

Code Combinations ContentsNo Condition (same as KXA function)Moved designated distanceDid not move designated distance within detection timeExceeded designated velocityDid not exceed designated velocity within detection timeOccurred within designated area, or entered designated areaOccurred outside designated area, or exited designated area

Notes:

• The term “and” in this context means that two events have occurred at the same time.• The term “or” means that either event has occurred.• The term "not" is determined at the end of the detection time set in KXS79 (Event Timer).


Timing ModesThe SC has three timing modes available for the Tracking Function:

1) KXB01: Wake up at a specified time, start observation of event, perform assigned functions and transmit.§ The SC wakes up at the specified time and observes the specified event for the period set by KXS79

(Event Timer). After an additional 5 minute period has elapsed, the SC powers down.

§ Six times can be specified. Each event timer period must be more than 30 minutes apart.§ This command cannot be used in conjunction with KXA01 02, 03, 04 or with KXB02, 03.

2) KXB02: Wake up for one specified interval, start observation of event, perform assigned functions andtransmit.§ The SC wakes up for one specified interval and observes the specified event for the period set by

KXS79 (Event Timer). After an additional 5 minute period has elapsed, the SC powers down .§ When the interval is less than the detection time set in KXS79, the SC evaluates the interval as

identical with detection time (requested interval = detection time ). When interval = 0, KXB02 willcause a continuous power ON mode. That is, SC observes the event continuously and when theevent has occurred, the SC transmits the assigned messages. When detection event is specifiedwith the (NOT) mode, the SC continuously observes the event until the period set in KXS79 hasended.

§ This command cannot be set with KXA01, 02, 03, 04 or with KXB01, 03.

3) KXB03: Wake up upon satellite arrival, start observation of event, perform assigned functions andtransmit.§ The SC powers on at satellite arrival time and observes the event for the period set by KXS79. After

an additional 5 minute period has elapsed, the SC powers down .§ This command cannot be set with KXA01, 02, 03, 04 or with KXB01, 02.


Notes:

• Power Down Mode (KXS37)After setting KXB01, KXB02 or KXB03, Power Down mode is automatically enabled (KXS37=1), and theSC will power down.

Max. Observation period (KXS79) (Observation Period ends after event occurrence)

5 min Power On Power Down

The SC powers on for the specified time. During the observation period, GPS power is ON. When thespecified event occurs, GPS power is OFF. Normally, the SC keeps power on for 5 minutes to transmit anymessages in the inbound queue. If the SC cannot detect a satellite during this period, the SC will powerdown. If the SC is set to run a user application, the SC will keep power on.

• Quick Power Down (KXS64 )

Using the quick power down command, the SC can power down immediately after message transmissionoccurs.

Note: The SC will ignore KXS64 in two situations:

1. The SC has messages in the inbound queue, or2. The SC is set to run a User Application.


KXB01 - Wake at Specified Time(s)

Wake up at a specified time, wait for a designated event that meets specified conditions, performassigned functions, and transmit.

Up to seven functions can be assigned in each of six timed events. Variable T assigns a number tothe timed event. The minimum time between events is 30 minutes. The Event Timer command(KXS79) determines how long the SC waits for an event. Each event occurs at the time designatedby variables HH and MM. Variables LH and LM determine the difference in time between a chosentime zone and GMT. Variable C specifies the event conditions code summarized in the EventCondition Codes table (page 23). Variable A is the Originator/Recipient address as defined in theORBCOMM serial specification. Variables D1 ~ D7 are the functions performed in each event.

Example: To transmit a position report and the I/O port condition to O/R Indicator 1 twice daily at1:30 Eastern Standard Time (EST) in the USA when the SC detects movement in excess of onehundred miles (designated distance set by KXS56 - Distance Select, KXS56=1000, 1):

KXB01=1,-5,0,1,30,01,2,1,2 <Return>

To clear all functions:

KXB01= 0 <Return>

When the KXB01, KXB02 or KXB03 commands are entered, the Power Downmode will be automatically activated (KXS37=1, Power Down mode - On).During the observation period, GPS remains powered on until the assignedevent occurs. 5 minutes after the end of the period set by KSX79 (EventTimer), the SC will power down.


KXB02 - Wake at Time Interval

Wake up for one specified interval, start observation of event, perform assigned functions, andtransmit when event meets the designated condition.

Variables LH and LM define the difference in time between a chosen time zone and GMT.Observation starts at the time specified in variables HH, MM and I on the command line during theperiod set by KXS79. Users can set a fixed interval from 1 minute to 10080 minutes. When therequested interval is less than the observation time set by KSX79, the interval is automaticallyevaluated as the value of KXS79. When the requested time interval is set to 0, the SC observesthe event continuously. Variable C defines the event conditions code summarized in The EventCondition Codes Table on page 20. If the event meets the condition, the SC performs assignedfunctions and transmits. Variable A is the Originator/Recipient address as defined in theORBCOMM serial specification. Variables D1 ~ D5 are the actions the function is to perform.

KXB02 =+1,30,4,0,180,03,3,3 <Return>

The speed threshold is set by KXS58. In this example KXS58=80,1. When theKXB01, KXB02 or KXB03 commands are entered, the Power Down mode willbe automatically activated (KXS37=1, Power Down mode - On). 5 minutesafter the end of the period set by KXS79, the SC powers down.


KXB03 - Wake Upon Satellite Arrival

Wake up upon satellite arrival, start observation of event, perform assigned functions and transmit.

SC powers on at satellite arrival time, then starts observation during the time period set by KXS79.A sleep interval timer is available to conserve battery power. The variable I defines the minimumsleep interval. Variable A is the Originator/Recipient address as defined in the ORBCOMM serialspecification. Variables D1 ~ D5 are the actions the function is to perform, as defined below.

Set-Up Commands

Using the Set-Up Commands

The Set-Up Commands allow the user to precisely configure the SC for highly customizedapplications. All of the 87 commands retain their settings via internal battery, and the entirecommand set can be returned to the factory default values if desired (see "Special Commands").Further, the default values for each command are listed in this manual should it be necessary toreset individual commands.

Note that the Set-Up Command set probably contains more commands than required by anyparticular application. The interface was designed to handle every possible data communicationsapplication suitable for use within the ORBCOMM system.

Default is 1.0, 0

USAGE>KXS56=3.6,1 <Return>KXS56=3.6,1


KXS57 - Area Select

Departure from a specified area can be used as one of several event triggers for the Trackingcommands. The Area Select command defines the specific area as a circle with a center point,radius and distance unit.

The center point is specified using latitude and longitude coordinates with the variables LAT andLON respectively. Each of these coordinates can be specified to the 10-3 degree.

The radius is defined using the variables R and U. R is the length of the radius where the length ismeasured in units determined by the variable U. Radius length can be between 0.1 and 5000 unitsin 0.1-unit increments.

COMMAND STRUCTUREKXS57 = LAT, LON, R, U <Return>

LAT: Center position of circle (latitude) (-90.0000 - +90.0000)LON: Center position of circle (longitude) (-180.0000 - +180.0000)R: Radius (0.1 - 5000)U: Unit

0: Km/h1: Mile/h2: Knot (NM/h)

Default is 10,0

USAGE>KXS58=55,1 <Return>KXS58=55,1

Due to inherent characteristics of the GPS system, a minimum of 5units is recommended to minimize false triggers.


KXS59 - Send Transmission Log to DTE

A transmission record is created each time the SC transmits or attempts to transmit. Thetransmission records are stored in the transmission log containing up to 20 records. When thetransmission log is full, the oldest record will be deleted to make room for the newest record.

Enabling KXS59 will cause the SC to send the transmission log to the DTE whenever the log is full.


0: Do not send1: Send when fullDefault is 0



KXS60 - Data Format

Select the format of data transmitted when using KXA/KXB commands. The format can be text orbinary for receiving position/speed/direction, digital I/O port status and analog port status. Use ofthe Binary and 6 Byte / Reduced Byte formats help to reduce the total transmission data size.


0: TEXT1: BINARY2: 6 BYTE / REDUCED BYTE [ > Revision F]Default is 0


When KXS60=2 and KXS25 (GPS Data Format) = 0 (LAT/LON Sentence Mode), a 6 byte positionreport will be sent.

When KXS60=2 and KXS25=1 (NMEA Sentence Mode), Altitude, Speed and Direction data areadded to the LAT/LON bytes for a total greater than 6 bytes, but less than KXS60=1 (Binary).

As a rule, the difference between KXS60 settings 1 and 2 is that setting 2 removes the DataCode and GPS Counter bytes from the message.

Both examples above involve a Position Report request ONLY. Additional data (e.g., PortStatus) will add to the number of bytes sent.

See Appendix D for full detail on the data structure.

6 byte conversion algorithm is defined in Appendix D and is different from ORBCOMM's 6byte format!

Fixed messages are sent in text type, regardless of KXS60 setting.


KXS61 - RS232 Driver Auto Shut Down

To conserve power, the SC can automatically turn off the RS-232 port when the SC is notcommunicating with the DTE. The RS232 Auto Shut Down function allows the user to selectbetween having the RS232 port continuously on (S=0) or having the SC manage power to the portproviding power only as needed (S=1).

This function is effective only in Protocol (Packet communication) Mode.


0: Off1: OnDefault is 0


When KXS61=1 (ON), the CTS line is set to OFF. A DTE communicating with anSC in this configuration should be set to "no CTS“ as well.

In addition, setting KXS61 to 1 disables KXS40 (Power Save Mode).

When SC is first powered on, this function will be invalid for one minute.


KXS62 - GPS Output Pulse Error Message

On Revision G units using KXS54 (Output Pulse Mode Setting), no GPS pulse will be generatedwhen the GPS circuit is unable to calculate a stable position. When the GPS Output Pulse ErrorMessage is on (M=1), the SC will send an “Output Pulse Error” message if GPS pulse cannot begenerated at the specified time per KXS54. When M=0, no message error message is sent.


0: No error messages1: Error messages to DTEDefault is 0

Default is 0


KXS67 can only be set to 1 when a UAP is loaded.


KXS68 - Serial Port Settings

The RS232C serial port can be managed by either the system or a User Application. When S=0,the SC controls the port. When S=1, the UAP assumes control.


0: Normal (Main system manages port)1: User Application manages port2: Reserved

Default is 0


User applications must be loaded if KXS68 is set to 1. After user application usage,KXS68 must be set to 0 in order to achieve serial communication between the SCand DTE.


KXS69 - Outbound Data Route Management

The Outbound Data Route can be managed by the SC, the user application software, or both.KXS69 allows the user to choose which system manages the Outbound Data Route.


0: Managed by main system (normal mode)1: Managed by user application2: Managed by both user application and main system

Default is 0


User application software must be installed to set KXS69 to 1 or 2.

KXS69 must equal 0 when KXS68 = 0

When KXS69=2, both systems (main and user application) must complete thereceiving process before Outbound queue can be cleared.

If condition of [KXS69=0 and KXS68=1] or [KXS69=2 and KXS68=1] should occur,main system loses control of Outbound queue, possibly causing overflow condition.For this reason, these combinations are NOT recommended (see table below).

KXS69=0 KXS69=1 KXS69=2KXS68=0 OK OK OKKXS68=1 X OK X


KXS70 - User Application Debug Mode

SC will output debug information to DTE when debug mode is set to ON.

Default is 0


KXS70 can be set to 1 ONLY when a User Application is loaded.


KXS71 - Remote Configuration Password

A password can be created for added security when configuring the SC over the ORBCOMMnetwork. When activated, command parameters cannot be modified unless the password isappended to the end of the message. (See page 3 for more detail.)

Setting KXS71 to a value other than the default automatically activates the last four digits of theSC's serial number as a secondary password to the assigned password.

Four characters must be used to define the password. Valid characters are 0 to 9 and A to Z(capital letters only). Setting the password to “0000” disables this function.

COMMAND STRUCTUREKXS71 = CCCC <Return>

C: 4 characters (0-9, A-Z)Default is 0000

USAGE>KXS71=AZ90 <Return>KXS71=AZ90

Password is deactivated when KXS71 is “0000”.

Only KXS and the KXA/KXB commands can be changed remotely; userapplication software cannot.

KXS76 - Satellite Elevation

Sets the minimum elevation angle (in degrees) that the SC will respond to by recalculating the waketime using satellite ephemeris data. Only wake portion (satellite entering view) of power ON cycleis affected by KXS76.

COMMAND STRUCTUREKXS76 = E <Return>

E: Elevation 0 – 45 [Degrees]Default is 5


Under circumstances in which a building or mountain blocks the SC's line ofsight, using KXS76 allows the SC to ignore low satellite angles, therebyimproving system reliability and conserving power.


KXS77 - Message Body Transmission in Byte Mode

The message body can be transmitted to the DTE in either Protocol (packet) or Byte mode. Whenthis command is activated (S=1) the SC will transmit the body of the message to the DTE in Bytemode.


0: Normal (Protocol Mode)1: Byte mode (message body only)

Default is 0


KXS77 is convenient for transmitting data or commands to a personal computer oranother communication device. This command only effects communication betweenthe personal computer (or other DTE) and SC.

This command effects only the message body. The subject, address and other partsof the message are always transmitted to the DTE in Normal (Protocol) mode.


Enhanced GlobalGrams

KXS77 may be used to transmit an “Enhanced GlobalGram.”

The SC alone cannot differentiate between a normal GlobalGram and an Enhanced GlobalGram.When Enhanced GlobalGram usage is desired, ORBCOMM must be notified via the provisioningprocess. In addition, KXS80 (GlobalGram Message Format) must be set to 1.

KXS78 - Buffer Full Message

Activating the Buffer Full Message command (S=1) will cause the SC to transmit a “Buffer Full”message to the DTE. The buffer full message will be transmitted to the SC only in byte mode.


0: No message1: “Buffer Full” message

Default is 0


The Buffer Full Message command can be used in conjunction with KXS45(Inbound Message Treatment) to assist the DTE in managing the inbound queue.


KXS79 - Event Timer

When using the Tracking (KXB) commands, the SC will wake up at the assigned time and wait for adesignated event. When the designated event meets the specified condition(s), the SC will performthe assigned function(s) and transmit.

The Event Timer command determines the period of time – in minutes – that the SC will wait for adesignated event. The SC will power down five minutes after this period has ended. (Refer to"Tracking Commands" section [page 19] for additional detail.)

Events are designated in KXB01, KXB02, and KXB03.


T: Time (5 - 20) [min]Default is 10



KXS80 - GlobalGram Message Format

Selects the SC-terminated GlobalGram format. This parameter is referred to when the SC receivesGlobalGram data and KXS77 is set to 1.


0: GlobalGram1: Enhanced GlobalGram

Default is 0

KXS81 - SC Terminated Message MMA (MaximumMSN Age)

(> Revision F)

Time interval after which the stored MSN (Message Sequence Number) becomes outdated. Oncea stored MSN becomes outdated, all messages delivered to the receiver will be considered newmessages, regardless of the MSN value.


T: Time (0-3932100) [sec]Default is 3600 (60 minutes)


Use KXS81 to reduce duplication of messages.


KXS82 - SC Terminated GlobalGram MMA (MaximumMSN Age)

(> Revision F)

Time interval after which the stored MSN (Message Sequence Number) becomes outdated. Oncea stored MSN becomes outdated, all GlobalGrams delivered to the receiver will be considered newGlobalGrams, regardless of the MSN value.


T: Time (0-15300) [sec]Default is 300


Use KXS82 to reduce duplication of messages.


KXS83 - Digital Output Default Value

(> Revision F)

Allows user to set the default level of the 2 digital output ports. Setting affects both ports.

COMMAND STRUCTUREKXS83 = V <Return>

0: Low1: High

Default is 1



KXS84 - Roaming Capability

(> Revision F)

Selects type of roaming mode to be used by the SC. KXS84 and KXS85 (GCC ID of RoamingMode) allow for additional GCCs to be addressed along with the GCC selected by KXS01, allowingthe SC to be used in other parts of the world without resetting KXS01.


0:OFF (GCC selected by KXS01)1:ON (Send message to GCC as set by KXS85)2:ON (Allow satellite in view to determine destination GCC)

Default is 0


SC must be registered with all desired GCCs through ORBCOMM.


KXS85 - GCC ID of Roaming Mode

(> Revision F)

Selects the GCC(s) to be used by the SC when KXS84=1. Up to 12 GCCs can be selected.

COMMAND STRUCTUREKXS85 = B, G <Return>

B: Block (0-11)G: GCC ID (0-255)Default is 0,0,0,0,0,0,0,0,0,0,0,0

USAGE>KXS85=0,120 <Return>KXS85=120,0,0,0,0,0,0,0,0,0,0,0>KXS85=1,121 <Return>KXS85=120,121,0,0,0,0,0,0,0,0,0,0>KXS85=2,123 <Return>KXS85=120,121,123,0,0,0,0,0,0,0,0,0>KXS85=3,130 <Return>KXS85=120,121,123,130,0,0,0,0,0,0,0,0

In this example, GCCs 120 (Italy), 121 (Malaysia), 123 (Brazil) and 130 (Japan) are stored inmemory blocks 0, 1, 2 and 3, respectively.

To delete a location, enter the memory block number and 0. For example, to delete the GCC inmemory block number 2:

>KXS85=2,0 <Return>KXS85=120,121,0,130,0,0,0,0,0,0,0,0


KXS86 - Day of the Week Mode

(> Revision F)

Messages created by the KXA/B commands (except for KXA06) can be sent on any or all days ofthe week. On days not selected, the message will not be created.

COMMAND STRUCTUREKXS86 = XXXXXXX <Return>

X: (0-1)

Each day is selected by setting the appropriate bit of the command code, as shown below.

1 0 1 0 1 0 1 Sun Mon Tues Wed Thu Fri Sat

0: Day not selected1: Day selectedDefault is 1 1 1 1 1 1 1

USAGE>KXS86=0101010 <Return>KXS86=0101010(Message will be sent Monday, Wednesday and Friday.)

Messages created on previous days that stall in inbound queue (e.g., no satellite)will still be sent as soon as possible, regardless of KXS86 setting.

On unselected days, the SC does NOT assume a "power off" mode. The unit willcontinue to cycle between sleep and wake cycles per the KXA/KXB commands.


KXS87 - GPS Quality Threshold

(> Revision 4.x)

The GPS Quality Threshold setting checks the PDOP (Position Dilution of Precision) value in eachdata string outputted by the GPS section in the SC. The SC then selects only the strings in whichthe LAT/LON data is under the assigned threshold.


T: Threshold (1-10)Default is 10


The default setting of 10 allows for the best positional accuracy at the expenseof getting less data strings for calculation, due to the increased level of filteringinvolved. Therefore, when using the SC in "reduced signal" areas (e.g., citieswith tall buildings), it may be necessary to try a lower threshold value, since thedefault setting could result in a degradation of positioning performance.


KXS88 - Watchdog Mode

(> Revision 4.x)

Three levels of resetting activity are available using KXS88. All operate by monitoring the RXactivity of the SC, checking at 2:27:30am (local time) every day.

Option 1 (software reset) will "soft-boot" the unit on every 24 hour cycle point, whether RX activityhas occurred or not, since errant software operation may not always cease the normal RX function.

Option 2 (hardware reset) will perform a power-cycling type of reset upon a problem reported withRX function only.

Option 3 (both) allows a software reset to occur every 24 hours with normal RX activity, and ahardware reset only when the RX function does not occur over the same 24 hour span.


0: No reset1: Software watchdog reset active2: Hardware watchdog reset active3: Both software and hardware watchdog activeDefault is 2


In the case of normal activity occurring on the 24 hour cycle point (2:27:30amlocal), the reset functions will wait 1 hour before performing their resets to allowcompletion of the current task.

Normal activity is defined as SC sending/receiving message to/from GCC, SCcommunicating with DTE, SC in Command mode, SC writing to backupmemory area.

KXOB - Clear Outbound Queue of SC

Clears the contents of the SC's Outbound Queue.

COMMAND STRUCTURE:

KXOB <Return>

The Outbound queue of the SC will be cleared.

USAGE>KXOB <Return>KXOB : OK


KXUTC - Check/Set Internal Clock

Under certain circumstances, it may be necessary to reset the unit's internal clock to current UTC(GMT) time. If actual UTC time is known, it can be entered directly without time zone information(Hour and Minute of Time Zone set to zero). If current local time is used, however, then the timezone data must be input as well. The Usage examples below show both formats.

COMMAND STRUCTURE:

KXUTC=LH,LM,DY,DM,DD,TH,TM,TS <Return>

Hour of Time Zone(-11-+12) Current Second

Minute of Time Zone(00 or 30) Current Minute

Year Current Hour

Month

Date

USAGE

When checking the internal timer:

>KXUTC <Return>KXUTC= -5,0,98,8,28,16,40,0

When setting the internal timer, without using time zone data:

>KXUTC=0,0,98,8,28,21,40,00 <Return>KXUTC=+0,0,98,8,28,21,40,0

The internal clock is adjusted to the exact time when the ORBCOMM satellitesignal is received, provided initial setting is +/- 60 minutes. However, it isrecommended that the setting is as close to the correct time as possible.

When inputted time is off by more than a minute, the internal clock does notupdate instantaneously. Rather, about one second must elapse to correct foreach minute of initial time error. So, if inputted time was wrong by 30 minutes,the SC requires about 30 seconds to synchronize to the correct time in thesatellite.

Date (YY/MM/DD) is NOT corrected by satellite.

Setting new time will clear all current satellite ephemeris data from SC'smemory.

Appendix A: Understanding the Modes of Operation

The ORBCOMM Command SetThe ORBCOMM command set uses two serial port interface modes for communication: the primaryProtocol mode, and Byte mode.

Protocol modeIn Protocol mode, the communication between SC and DTE is based in the Serial InterfaceSpecification as prepared by ORBCOMM. The DTE can send and receive messages, reports,commands and "GlobalGrams", as well as obtain time-of-day and position estimates.

This is the SC's default mode of operation. If desired, the default can be changed to Byte Modeusing KXS31 (Operation Mode).

Byte modeByte mode is used primarily for direct-connection communication between the SC and PC/DTE. Inthis mode, data bytes are generated without header, length field, or checksum information, allowinga more efficient transfer of large messages. However, the transfers are less robust due to the lackof acknowledgements and checksums.

Configuring the SC to identify Byte mode data can be done by configuring these Panasoniccommands: KXS32 (Byte Mode Trigger), KXS33 (Byte Mode Timeout), KXS34 (Byte ModeLength), KXS35 (Byte Mode TX SOM/EOM, RX SOM/EOM).

The Panasonic Command SetThe Panasonic Command Set is designed to simplify the programming of the SC. Using its foursubsets (Transmission Commands, Tracking Commands, Setup Commands and SpecialCommands), a user can configure the unit to perform almost any desired function within theORBCOMM system limits.

Furthermore, SC owners can develop their own highly specialized applications using Panasonic'sSoftware Developer's Kit (SDK). These User Application Programs (UAPs) begin as "C" codebased programs before being converted to a custom format for loading into the SC. Once loaded,the UAP resides in a dedicated 4KB block of memory, which can be increased to 14KB usingKXS66 (Ram Manager).

Definitions of Key Terms

Application A software program or program package that makes calls to the operatingsystem and manipulates data files, thus allowing a user to perform aspecific job.

AsynchronousCommunication

A method of sending data in which the bits can be sent at random times.With Asynchronous transmission, data transmission is not synchronized toa clock. Each character is transmitted one at a time with a “start” bit at thebeginning and one or more “stop” bits at the end. Any amount of time canelapse before the next character is sent. This allows the time betweentransmitted characters to vary, but also requires more interface logic todecode each character of data. It’s a slower (but more accurate) methodthan synchronous transmission, because if transmission is interrupted,only one bit of data will be lost. This is the means by which most smallcomputers communicate.

Baud A measure of the speed of data transmission. Baud and bit rate are thesame for direct equipment interconnections (e.g. via RS-232). Baud andbit rate are not the same for modulated data links, whether wire or radio.

Baud Rate Measure of data transmission speed, expressed in bits per second or bps.

Bit Binary Digit. The smallest unit of information into which digital data can besubdivided and which a computer can hold. Each bit has only two values,one or zero.

Bit Rate The rate at which bits are transmitted over a communication path.Normally expressed in bits per second (bps).

Byte 1) The amount of storage required to represent one character; a byte is 8bits. 2) A binary character operated on as a unit and usually shorter thanone word.

DataCommunicationsEquipment (DCE)

The equipment that provides the functions required to establish, maintainand terminate a communications connection. Any equipment thatconnects to DTE using an RS-232 or CCITT V.24 standard interface.

Datum Refers to a mathematical model of the earth. Many local datums modelthe earth for a small region

Default Setting A preset or initial value that is assumed to be the preferred or appropriateselection for most situations.

Appendices - 161

Doppler Positioning ORBCOMM’s capability for estimating (with 1 kilometer resolution) thelocation of an SC based on the apparent change in frequency of thesatellite’s downlink with respect to the SC.

Doppler Shift The apparent change in the frequency of a received signal due to the rateof change of the range between the transmitter and receiver caused bythe relative motion of the transmitter and receiver.

DTE Data Terminal Equipment. Example is a desktop computer.

Elevation Angle The angle between the line of sight vector and the horizontal plane.

Elevation Mask Angle A measure of the minimum elevation angle, above the horizon, abovewhich a satellite must be located before the signals from the satellite areuseable. The elevation mask angle is used to prevent receivers fromcomputing position solutions using satellites which are likely to beobscured by buildings or mountains.

Ephemeris A set of parameters that describe the satellite’s orbit very accurately, usedby the receiver to compute the position of the satellite. This information isbroadcasted by the satellites.

Firmware Set of software instructions that are set, permanently or semi-permanently, into integrated circuitry.

Frame A group of bits sent over a communications channel, usually containing itsown control information, including address and error detection. The exactsize and make-up of a frame depends on the protocol used.

Frequency The number of vibrations per second of an audio or radio signal.Measured in hertz (Hz), kilohertz (kHz) or megahertz (MHz).

Gateway ControlCenter (GCC)

The GCC acts as the Operations Center for all Gateway activities. Allcommunications must pass through an ORBCOMM GCC.

Gateway EarthStation (GES)

The GES provides interconnection between the OMS and the satelliteconstellation. The GES consists of medium gain tracking antennas, RFand modem equipment, and communications hardware to send andreceive ORBCOMM data packets. A single GES can communicate withmultiple satellites within its main beam.

GlobalGram A single, self-contained packet sent or received by a subscribercommunicator (SC) when no Gateway can be accessed by the satellite.Packet size is limited to 290 bytes.

Global PositioningSystem (GPS)

A constellation of 24 radio navigation (not communication) satellites whichtransmit signals used by GPS receivers to determine precise location(position, velocity and time) solutions. GPS signals are available world-wide, 24 hours a day, in all weather conditions.

L-Band The group of radio frequencies extending from 390MHz to 1550MHz. TheGPS carrier frequencies (1227.6MHz and 1575.42MHz) are in the L-band.

Message A logical partition of the user device’s data stream to and from theadapter.

Appendices - 162

Mode A particular functional condition or status. Many systems capabilities areactive in one Mode of operation, but not in another.

Network ControlCenter (NCC)

The NCC houses the computer systems and personnel (GatewayOperators) responsible for managing the Satellites and the USORBCOMM Gateway and for supporting Licensee’s ORBCOMMGateways.

ORBCOMM The ORBCOMM mobile, wireless satellite communications system is awide area, packet switched, two-way data system. Communications toand from a mobile ORBCOMM subscriber to the Gateway is accomplishedby use of a constellation of Low Earth Orbit (LEO) satellites.

ORBCOMMCommands & ControlNetwork (OCCNet)

Consists of the routers, bridges and modems that interconnect theORBCOMM Gateway elements - in particular the GMS, GSS and GESs,through which command and control messages are passed.

ORBCOMM MessageSwitch (OMS)

The OMS consists of computer and data communications equipment thatperform the actual message processing, including message and protocoltranslation, route determination, subscriber service provisioning, andusage detail recording.

Outbound Messages(OB)

Messages handled within ORBCOMM’s internal network (message trafficsent from the firewall to a GES).

O/R Originator/Recipient. Code name used by ORBCOMM to identifymessage and report addressees, either in code (speed dial) or emailformat.

PIN Code The OMS maintains a 4-digit number Personal Identification Number (PIN)code for each SC.

Port 1) For hardware, a connecting component that allows a microprocessor tocommunicate with a compatible peripheral. 2) For software, a memoryaddress that identifies the physical circuit used to transfer informationbetween a microprocessor and a peripheral.

Queue A line or list formed by items waiting for service, such as tasks waiting tobe performed, stations waiting for connection, or messages waiting fortransmission.

Appendices - 163

Random-AccessMemory RAM)

Memory in which information can be referred to in an arbitrary or randomorder. The contents of RAM are lost when the unit is turned off.

Rise/Set Time Refers to the period during which a satellite is visible; i.e., has an elevationangle that is above the elevation mask. A satellite is said to “rise” when itselevation angle exceeds the mask and “set” when the elevation dropsbelow the mask.

RS-232 A communication standard for digital data that specifies a number ofsignal and control lines. RS-232 is often associated with a 25-pinconnector called a DB-25.

SerialCommunication

A system of sending bits of data on a single channel one after the other,rather than simultaneously.

Serial Port A port in which each bit of information is brought in/out on a singlechannel. Serial ports are designated for devices that receive data one bitat a time.

Start Bit In asynchronous transmission, the start bit is appended to the beginning ofa character so that the bit sync and character sync can occur at thereceiver equipment.

Stop Bit In asynchronous transmission, the stop bit is appended to the end of acharacter. It sets the receiving hardware to a condition where it looks forthe start bit a new character.

SubscriberCommunicator (SC)

Small message processing devices used to access the ORBCOMMsystem.

Subscriber-Originated(SC-O) Messages

(Also known as Inbound messages).

Subscriber-Terminated (SC-T)Messages

(Also known as Outbound messages)
