2.8.5.2. Installing the UPS battery (If you are not going to install the UPS battery, you should skip this procedure). The UPS battery is a rechargeable NiCd battery. It is held in place by a narrow retainer and fastened with machine screws on both ends, and its ribbon cable is connected to the terminal block adapter. You must open the terminal to install this feature.

NOTE: The UPS battery has been discharged before shipment, thus it requires 51~58 hours to fully recharge. It will recharge as long as the MR350MKII is plugged into its power outlet and has DC power. It is recommended that the UPS battery be fully charged before running an application for the first time. The UPS battery will allow the application to run about 8 hours after losing AC power, depending on how many devices are used. If the terminal is already opened from the previous procedures, begin at step 3. Installation Procedure: (1) Turn the terminal over, so that the LCD faces down. (2) Unlock the main body (the lock is located on the bottom

side), and lift the backplate off the front cover. (3) Detach the terminal block adapter cable from the 24-pin

connector on processor board. (4) Turn the backplate over, so that the terminal block PCB

is facing you.

2.8.6. Reassembling the Terminal The MR350MKII is well suited for wall mounting, for mounting on flat surface, or for placing on a table. The metal backplate is designed as a back cover, with a wall mounting mechanism, thus you do not have to purchase any additional accessories for wall mounting. If you want to place the MR350MKII on a table or hang it on a wall, a bench mounting kit is available. If you plan to wall mount the MR350MKII terminal, you should skip this section and go to the next section Installing the Terminal on Wall. Installation Procedure: (1) Lay the terminal front cabinet face down on a flat surface. (2) Reconnect the terminal block adapter cable to the 24-pin

connector on the processor board. (3) Carefully slide the backplate onto the front cabinet so that its

brackets mesh with the cabinet slots properly (see figure below).

Chapter 3. System Kernel

3. System Kernel 3.1. Application Programming Interface The MR350MKII kernel includes three basic modules: device driver, file manager and DOS manager. The programmer can design the application programs by calling those available functions just as in the PC DOS environment. The ROM based operating system of the terminal provides emulated MS/DOS function calls. The calling and parameter passing conventions are identical to that of MS/DOS. A detailed description of the functions supported by the Terminal's subsystems, I/O interface, DOS manager and File manager are listed in appendixes A and B. The software to be run on the MR350MKII may be programmed by using 16bits Microsoft C/C++ or Borland C/C++, and the IBM PC macro assembler version 1.0 and later versions. Transaction data can be processed interactively with the computer or stored in a file.

NOTE when using Microsoft C/C++ : When program execution area is assigned less than 64K (see section 4.3) and a program of more than 64K is run, a run time error message, "Not enough space for environment", will be shown. In this case add following statements in main: /* mypgm.c */ _setenvp() { } main() {... ... ... } and link with: >LINK /NOE mypgm

3.2. Keypad Subsystem The keypad subsystem scans the key matrix, converts the scan code to its associated key value, and stores the value in the keyboard input buffer for program utilization. Note that the [SHIFT] key is not stored in the buffer, it is used to distinguish the alphabetic and numeric mode of associated key positions and provide an alternative key code. The following table shows the key values of each key.

3-40

Table of Key Values Key Value Key Value Key Value Key Value

3.3. Display Subsystem This subsystem provides the interface functions: Display character, Display string, Set cursor position, and Clear screen display. The display coordinates are organized as follows: Min Min Max Max Row Col Row Col 0 0 1 15 The origin (0,0) is always at the upper left hand corner.

3.4. Communications Subsystem The MR350MKII terminal communication subsystem consists of

1) point-to-point connection mode and 2) multi-point connection mode for network processing.

3.4.1. Point-to-point mode Either RS-232 or RS-485 ports can be used in point-to-point mode. Each port can be configured for input or output data by making DOS calls. To transfer files, a Kermit server can be invoked by selecting option 3) COM in the user command menu or by typing COM in the Ready prompt and a Kermit utility should also be run on the Host side in order to complete the data connection.

3-41

3.4.2. Multi-point mode Either RS-232 or RS-485 ports can be also used in multi-point mode. When an RS-485 port is assigned to serve in multi-point mode, up to 32 terminals can be accessed per channel, when the RS-232 port is selected, the number of accessible terminals is limited by the number of available RS-232 ports on the host computer. There is also a multi-point communication protocol built into the MR350MKII for data communication in multi-point networking.

3.5. Real time clock subsystem This subsystem allows the program to set and read the system date and time of the MR350MKII.

3.6. Relay output and Digital input subsystem The MR350MKII supports two contact relay ports and four photocoupler input ports for digital signal input/output control, where pins #11/12 and pins #13/14 can also be assigned to the RS-232, and barcode scanner port (see Terminal Block Adapter on page 2-19).

3.7. Bar code / Magnetic stripe / Wiegand / Smart card The MR350MKII has two ports for connecting four different interface reader. One of the two ports, as scanner port, is dedicated to bar code reading via bar code wand, CCD, laser diode scanner, bar code slot reader, and the terminal supports reading of Code 39, Code 128, Codabar, Interleaved 2 of 5, UPC and EAN. Please be noted, the secondary magnetic stripe reader besides the built-in one, is only valid on connecting to the terminal block adapter.

NOTE: The CCD , laser diode scanner and barcode wand are only supported when connected through the scanner port. If terminal block pins #13/14 are set to scanner port, only the barcode wand or the slot reader are supported.

The other port, as build-in reader port, is mainly designed for connecting a card reader for bar code, magnetic stripe, proximity and smart card reader. The proximity reader can be magnetic stripe reader(MSR) interface or wiegand interface, it up to customers choice. MR350MKII only can support single track 1, 2 or 3 magnetic card stripe. These two ports can work at the same time.

3-42

NOTE: Please be noted, the MR350MKII can automatically detect the type of badge reader. If a different type of build-in reader is selected, the first attempt of reading the card will be used to detect the right type and the data will not be accepted. If a right type is selected, the first attempt of swiped data will be accepted immediately.

Chapter 4. Data Structure

4. Data Structure The MR350MKII system control data structures are outlined in the following diagram. The system kernel uses the File Allocation Table (FAT), File Handle Table (FHT), Communication Control Table, Device Control Table and Key Alias Table. The following sections will describe each one of these control tables. The description includes a "typedef" part and the "default" values of the table.

Terminal Application EXEC Terminal Control Table Device Control Table Key Alias Table

File Allocation Table File Handle Table Comm Control Table RS232&RS454

4.1. Device Control Table The device control table contains the MR350MKII peripheral configuration information including barcode scanner port, badge reader port, LCD display, keyboard and buzzer output information. The barcode scanner is controlled by a separate data structure and barcode control table, to be discussed later.

4.2. Type Definition typedef struct { BYTE scanner; BYTE badge; BYTE lcd_backlight; BYTE buzzer; BYTE keylock; BYTE buzzer_volume; } DEV_CONFIG; scanner: 'N' = enable scanner port 'F' = disable scanner port (default) badge 'B' = enable badge port for barcode slot reader (default) 'M' = enable badge port for magnetic card reader 'D' = disable badge port lcd_backlight: 'N' = set LCD backlight ON

Barcode Control Table The MR350MKII supports decoding software to automatically discriminate bar code symbologies: Code 39, Code 39 Full ASCII, EAN-8, EAN-13, UPC-A, UPC-E, Code 128, Codabar and Interleaved 2 of 5.

4.3.1. Type Definition

4-49

4.4. Communication Control Table of Host port The communication control table is applicable to configure the host port of the MR350MKII. The communication control table specifies all communication parameters between the host system and the MR350MKII. When a hard reset command is issued via keypad input or host command sequence the default communication parameters are restored. The host system may then configure most MR350MKII parameters by issuing host command sequences. The host command sequences will be listed later in appendix B.

4.4.1. Type Definition typedef struct { BYTE baud_rate; BYTE stop_bit; BYTE data_bit; BYTE parity; BYTE protocol; BYTE address; WORD time-out;

} COM_CONFIG; The MR350MKII terminal communicates with the host via the host port. The communication baud rate may be programmed from 110 to 38.4K baud (bits per second). baud_rate: '0' = 110 bits per second '1' = 150 '2' = 300 '3' = 600 '4' = 1200 '5' = 2400 '6' = 4800 '7' = 9600 (default) '8' = 19200 '9' = 38400 stop_bit: '1' = one stop bit (default) '2' = two stop bits data_bit: '7' = 7 data bits '8' = 8 data bits (default) parity: 'N' = None parity (default) 'O' = Odd parity 'E' = Even parity protocol: 'M' = Multipoint (default) 'F' = None protocol

4-50

address: 'A' = terminal address ID for Multipoint mode (default)

Each MR350MKII must be assigned a unique communication address when it is used in a Multipoint environment. The address is used by a host or concentrator to perform polling functions. Characters 'A'-'Y' and '0'-'6' are used for assigning an address ID of each terminal.

time-out: '02' = polling time-out two cycle periods (default). '02'-'FF' in hex format.

The value of this setting is specified for the communication time-out. If the MR350MKII does not receive a response from the host system within the number of time-out cycle periods, the MR350MKII regards the communication as unsuccessful and the transmission is then aborted. If the time-out value is set to zero, no time-out check is performed by the MR350MKII.

4.5. Terminal Control Table (available for host port only) The terminal control table is meaningful only if the MR350MKII operation switch is set to "terminal mode". All other operational modes ignore the terminal control table.

4.5.1. Type Definition The terminal control table is defined by the following typedef TERM_CONFIG. There is only one instance of the TERM_CONFIG data structure:

typedef struct { char terminal_id[8]; /* terminal id */ BYTE online; BYTE echo; BYTE autolf; /* auto LF */ BYTE mode; BYTE linepage; /* line or page block */ BYTE lineterm; /* line terminator */ BYTE pageterm;/* page terminator */

} TERM_CONFIG; Each MR350MKII "terminal" is identified by an ASCII string. There can be up to seven characters in a terminal identification string. The

4-51

identification entry in the TERM_CONFIG table must be terminated by a character, ASCII_Z (hex 0), as in C language convention.

online: 'R' = set to Remote and transmit data to the host port (default) 'L' = set to Local and do not transmit echo: 'N' = set to Echo and transmit displayed data to the host port 'F' = do not transmit

The above two variables, TERM_online and TERM_echo, are used to control transmission and display of the collected data, respectively. If TERM_online is set to Remote the MR350MKII will transmit data to the host, otherwise it will not transmit. If TERM_echo is set to Echo collected data will be displayed on the MR350MKII LCD, otherwise data will not be displayed.

autolf: 'N' = set not to append a LF after a CR 'F' = set to append a LF (default)

This variable instructs the MR350MKII to append a LF character whenever a CR is collected from an input scanning device.

mode: 'C' = set to Character mode 'B' = set to Block mode (default)

This parameter specifies either character mode or block mode free-format operation. The aforementioned form caching operation is only applicable when the MR350MKII is set in block mode.

linepage: 'L' = set line block mode (default) 'P' = set page block mode 'B' = set both line and page block modes

The linepage parameter is useful only if mode has been specified as 'B'.

lineterm: designates the termination character of line block mode (default = null) pageterm: designates the termination character of page block mode (default = null)

5-52

Chapter 5. Host Communication

5. Host Communication and ESC commands There are three classes of host communication activities:

(1) Host Sends Control/Configuration Commands to the MR350MKII

Almost all MR350MKII configurations and operations may be controlled by the host system via control commands. Configuration commands are used to set up system tables such as the communication control table. Control commands are used to abort MR350MKII operations, reset the MR350MKII, instruct the MR350MKII to execute an application program, or perform other functions related to operations. Configuration commands are normally issued by the host system during the initialization process. Control commands, however, may be issued at any time during normal operation or during a recovery action.

(2) Host Requests Data from the MR350MKII Two kinds of data are usually requested by the host system: MR350MKII system data and application data. Application data is the information which is input through keyboard or bar code scanning, system data is the information which is pertinent only to MR350MKII executives, e.g. file names, system parameters, etc. The MR350MKII transmits data depending on the protocol used.

(3) File Transfers Between the Host and the MR350MKII Executable files and data files are downloaded to the MR350MKII from the host or uploaded to the host from the MR350MKII. File transfers may use a special file transfer protocol to move data in a point-to-point or multi-point connection.

In the following sections we will first discuss the host communication commands and briefly describe their functions. Then we will examine in detail the protocol for each function.

5.1. General Control Commands 1. Hard Reset ( ESC H )

A hard reset command clears all the MR350MKII RAM memory content. It performs tests on all major hardware devices. Programs or data that have previously accumulated in the MR350MKII or previously been downloaded

5-53

by the host will be purged from the memory. Default system parameters are restored from the EPROM. The hard reset command does not have any parameter or value. The equivalent keypad invoking sequence is entering the supervisor mode and selecting an initialization command.

2. Abort ( ESC A ) Abort is the "soft reset" command. The MR350MKII terminates its execution and returns to ready mode. Programs and data that have been stored in the MR350MKII RAM space are preserved. The system parameters remain unchanged. The abort command does not have any parameters or values. The equivalent keypad invoking sequence is pressing the [SHIFT] and [F5/*] keys at the same time.

3. Execute ( ESC X filename ) The host system may instruct the MR350MKII to execute a program which resides in the MR350MKII RAM. The host issues the execute command with the executable program name as its parameter. The MR350MKII acknowledges with an ACK response if the program exists and starts execution. The execute command has one parameter, the file name. The execute command can also be invoked via the MR350MKII workstation menu.

4. Directory ( ESC D ) The directory command instructs the MR350MKII to return a list of available files in the RAM of the MR350MKII. The directory command has no parameters. The directory command can also be invoked via the MR350MKII workstation menu. When invoked from the keypad the directory is listed on the LCD display.

5. Erase ( ESC E filename ) The erase command deletes a file from the MR350MKII RAM. An ACK response will be given if the file existed and was deleted, otherwise an NAK response is generated by the MR350MKII. The erase command has one parameter, the file name. The erase command can also be invoked via the MR350MKII workstation menu.

6. Autoboot ( ESC O program name ) This command defines an autoboot program name in the MR350MKII. The autoboot program will be executed automatically each time the power is turned OFF and ON.

7. Password ( ESC P password ) To create or edit a supervisor password.

5-54

8. Get RAM size (ESC G) Get the MR350MKII? total RAM size, program execution memory, and free memory available for RAM disc.

9. Get filename of currently executing program (ESC I filename) When the command is received by the MR350MKII, the system will respond with the current executing program name or report that no program is running.

10. Check file existed and files size(ESC J filename) Check if the file is existed on MR350MKII or not. If file is exist, it will return its size

11. Set keyboard locking (ESC K state) Set the MR350MKII? keyboard locking state. There are three states allowed: UNLOCK, LOCK, or PARTIAL LOCK.

12. Change terminal address ID (ESC 5 ID) Assign a new terminal address ID to the terminal. Once the terminal address ID changes, it will take effect immediately without having to reset the terminal.

13. Deactivate UPS (ESC F) Deactivate the UPS on MR350. Once the command is sent, the UPS will not activate and support the power to the terminal during the main power is outage. This command is useful when the terminal is under maintenance or not used for long period.

14. Loopback test (ESC 9) The loopback test is used for testing the line communication. The testing

program run on host sends this command with test data to terminal and terminal echoes back the data to be verified by the program.

15. Buzzer Volume (ESC N) This command can remote changing MR350MKII's buzzer sound.

16. Supervisor password (ESC P) This command can remote changing MR350MKII's buzzer sound.

17. Get terminal ID (ESC R) This commcand can get terminal ID. The default terminal ID is "MR350"

18. Get terminal ID and version no (ESC v) This commcand can get terminal ID and version no. The default terminal ID is "MR350 V4.xx".

5.2. Configuration Commands Configuration commands from the host always follow the standard host command sequence: ESC, cmd, table. The cmd field actually specifies the object to be configured. The table field contains the data organized in a pre-defined format. 1. Terminal Configuration ( ESC T )

The terminal configuration command has the following format: ESC T termtable

This command takes the data structure "termtable" from the host and writes it to the MR350MKII internal terminal control table. The structure within "termtable" must conform to the TERM_CONFIG typedef (see section 4.5 on page 4-50) specified in the previous section. The new terminal control table takes effect immediately after the ESC T command has been successfully received.

2. Communication Configuration ( ESC C ) The communication configuration command has the following format:

ESC C comtable This command takes the data structure "comtable" from the host and writes it to one of the two MR350MKII internal communication control tables. The structure within "comtable" must conform to the COM_CONFIG typedef (see section 4.4 on page 4-49) specified in the previous section. The new communication control table takes effect immediately after the ESC C command has been successfully received. The MR350MKII will

5-56

reinitialize the corresponding communication port with its new parameters. For example, if ESC C instructs the RS-232 port to change the baud rate from 9600 to 1200 the MR350MKII will switch to 1200 right after the ESC C command has been received. The next host communication will use 1200 baud.

3. Device Configuration ( ESC V ) The device configuration command has the following format:

ESC V devtable This command takes the data structure "devtable" from the host and writes it to the MR350MKII internal device control table. The structure of "devtable" must conform to the DEV_CONFIG typedef (see section 4.1 on page 4-47) specified in the previous section. The new device control table takes effect immediately after the ESC V command has been successfully received.

4. Date/Time Configuration ( ESC M ) The date/time configuration command has the following format:

ESC M datetime This command allows the host system to initialize the MR350MKII real time clock function. The parameter datetime is an ASCII character string with the following interpretations: yyyymmddhhmmss. The first four characters represent the year. The next two characters represent the month, where January is 01. The fields after the month field represent the day of the month, hour (24 hour format), minute, and second, respectively. For example, command ESC M 199009262345 will initialize the MR350MKII clock to September 26, 1990. The time is 11:45 PM. The MR350MKII reconfigures the real time clock chip as soon as the ESC M command has been successfully received.

5.3. File Transfer Commands 1. Download ( ESC L filename )

The download command is used to transfer a binary executable program or data file from the host system to the MR350MKII. When the MR350MKII receives the download command it sends an ACK response back to the host and immediately puts itself into a file receiving state. The file receiving state is determined by a pre-assigned host protocol Kermit. The host system may start transmission of the file as soon as the ACK response has arrived.

5-57

The download command has one parameter, the file name. Download can also be invoked via the MR350MKII workstation menu. The upload command performs the opposite function of the download command. It is normally used to transfer a data file from the MR350MKII to the host system. This is the typical means of retrieving collected data in workstation mode.

2. Upload ( ESC U filename ) When the MR350MKII receives an upload command it puts itself in file transmission state and starts sending the designated data file. The file transfer protocol is determined by a pre-assigned host protocol Kermit. The host system waits for the arrival of the data file after it sends out the upload command. The upload command has one parameter, the file name. The upload command can also be invoked via the MR350MKII workstation menu.

5.4. Multipoint Protocol In Multipoint operation the MR350MKII uses an asynchronous serial multi-drop protocol for communication with the host computer. Note that to make this protocol operable an RS-232 to RS-485 converter is needed between the host and the MR350MKII. The terminal protocol consists of commands and responses of the following format:

Symbol Description => Transmission from host to terminal

5-58

Length of data block = 7 CS = ESC + L + A + . + E + X + E + ADDR + 7 CS1 = high nibble of CS + 40H CS2 = low nibble of CS + 40H

The ASCII data characters and their values are as follows:

STX 0x02 ETX 0x03 ACK 0x06 NAK 0x15 DC1 0x11 ESC 0x1B EOT 0x04 The maximum frame size including protocol control characters is 128 bytes. Transparent transmission of protocol control characters STX and ETX is achieved by preceding them with a '\' (backslash) character. Transparent transmission of the '\' character is achieved by sending two '\' characters consecutively.

Rule of data convention during data transmission: 1) One-byte data converted to two-byte data

\ convert to \\ 00 hex -- 1F hex convert to \ 80 hex -- \ 9F hex A0 hex -- FF hex convert to \ 20 hex -- \ 7F hex (excluding DC hex) 2) one-byte data transmitted as original data without converting other codes unchanged Host Transmissions Transmission Format Poll STX, ADDR Host Data STX, CMD, data, CS1, CS2, ADDR Acknowledgment ACK

5-59

Negative ACK NAK Terminal Transmissions Transmission Format Terminal Data STX, data, CS1, CS2, ETX Acknowledgment ACK Negative ACK NAK

5.4.1. Protocol Operation The terminal protocol operates as a multi-point stop and wait protocol. A station sends only one frame and then stops and waits for a response.

The following scenarios typify link transmissions: * Terminal has no data for the host: => STX ADDR STX ADDR ACK - if data is received correctly, or NAK - if an error has occurred

* The host sends a command to and receives a response from the terminal in one poll cycle; it then acknowledges receipt of the terminal command response:

=> STX, CMD, parms, ... CS1, CS2, ADDR

5-60

5.4.2. Example Using Host ESC Command The following commands are supported for download, diagnostic, and application data transfers. Each command and its parameters will be framed as shown before being transmitted; responses have the same format without the ADDR fields.

STX, CMD, parms, ... CS1, CS2, ADDR Example:

ESC H - Hard Reset and initiate power on test => STX ESC H CS1 CS2 ADDR
