CHAPTER 1 Introduction to Redwing CDMA

Redwin

FIGURE 1. Redwing front and back

CDMA Overview

Establishing an Internet Connection

The Redwing uses Sprint as an ISP (Internet Service Provider) to connect you to the Internet.

The Redwing's rugged form factor is ideal for industrial and commercial applications that require real-time communications. The Redwing provides cellular data communications for a variety of applications, such as public safety, traffic control, traffic metering, and more.

CDMA (Code Division Multiple Access) is the underlying digital radio network technology used by many cellular providers across the globe and is prevalent in North America. CDMA/1x pro-vides a digital cellular telephony system and can provide wireless Internet access at speeds between 60 and 80 kbps, with bursts up to 144 kbps. 1x is a data standard built on CDMA.

1x is highly secure. Originally developed based upon the “spread spectrum” pioneered by the US Department of Defense, security in 1x is obtained by spreading the digital information contained in a particular signal of interest over multiple coded paths, over a much greater bandwidth than the original signal.

Introduction to Redwing CDMA

Steps of a connection:

Dynamic vs. Static IP Addresses

As stated above, when your Redwing registers on Sprint’s network, it receives an IP address. There are two types of addresses on networks: dynamic and static.

• Dynamic addresses are assigned on a “need to have” basis. Your Redwing might not always receive the same address each time it connects with Sprint.

• Static addresses are permanently assigned to a particular account and will always be used whenever your Redwing connects to the Internet. The IP address will not be given to anyone else.

Most ISPs (cellular included) use dynamic IP addresses rather than static IP addresses since it allows them to reuse a smaller number of IP addresses for a large number of customers. A dynamic IP address is suitable for many common Internet uses, such as web browsing, looking up data on another computer system, or other client functions (such as data only being sent out or only being received after an initial request).

1. When your Redwing is powered on, it automatically searches for cellular service using CDMA.

2. Your Redwing establishes a PPP (Point to Point Protocol or “dial” up connection) link to Sprint’s network, also called registering on the network, and receives an IP address.

3. When your Redwing has received its IP address from Sprint, then it is ready to allow you to connect to the Internet.

FIGURE 2. Using the Redwing to connect to the Internet

Note: If your account with Sprint includes a dynamic IP address and you need a static IP, please consult your Sprint Data Sales Representative for more informa-tion about changing your account for static IP support.

If you need to contact your Redwing, a device connected to the modem, or a host system using the modem from the Internet, you need to have a known IP (such as one which is static) or domain name (an IP address which is converted by a DNS server into a word based name).

Introduction to Redwing CDMA

Common Uses for the Redwing

Caution: If you want to connect remotely to your Redwing using TCP/IP, the IP address given to your modem by the network cannot be a private or internal IP address (such as Data Link) unless you are on the same network or inside that net-work’s firewall (such as with frame relay).

Using Your Redwing to Connect to the Internet

To use your Redwing’s serial port to connect to the Internet from your computer, you need to con-nect the computer directly to the Redwing’s serial port with a straight-through serial cable and use Dial-Up Networking (DUN).

The Redwing’s rugged construction and cellular connection make it ideal for use in remote and/or industrial locations.

The Redwing is designed to work with legacy devices which do not need the advanced features of ALEOS.

FIGURE 3. Remote Internet Access


CHAPTER 2 Activating the Redwing

Redwin

Your Redwing needs specific parameters before it can operate on the CDMA network.

Quick Start Guide and Setup Wizard

The preferred way to activate and configure your Redwing to connect to the cellular network is via the AirLink Setup Wizard for Sprint. The Quick Start Guide will lead you through using the Setup Wizard.

Select Start, then All Programs, then AirLink Communications. Select Setup Wizard.

FIGURE 1. Setup Wizard

The latest Redwing Setup Wizard and Quick Start guide are on the product CD included with your modem and are available from the AirLink web site, http://www.airlink.com/support.

Note: To run the Setup Wizard, you will need the Microsoft .NET framework v.1.1 and Microsoft Windows 98, Microsoft Windows 2000, Microsoft Windows XP, or later.


Redwin

Activating the Redwing

Activating the Redwing using AT Commands

An alternate method to configure and activate your Redwing is by using AT commands sent directly to the modem with a terminal application (refer to the troubleshooting section, page 52). This method is recommended only in situations where the Setup Wizard is not available and/or the configuration for the Redwing is unusual.

Caution: While you can configure your Redwing using Wireless Ace or AceNet, it is not possible to activate the Redwing using either Wireless Ace or AceNet.


CHAPTER 3 Circuit- Switched Configuration

Redwin

However, for customers who have unintelligent machines who still need to have the modem 'ready' to behave in a certain way (such as Auto-Answering circuit-switched data calls), there is a feature in the modem called the INIT STATE.

INIT State

The Auto-INIT command string is comprised of up to 40 characters, the order defining the sequence of the initialization. The command sets the modem for the desired 'ready' configuration each time it powers on.

Configuring Circuit-Switch

The Redwing does not have any internal intelligence nor does the Redwing C3110 or C3116 have the ability to SAVE individual settings like a conventional modem (the Redwing C3111 can save settings internally). Therefore, the best machines for use in circuit-switched mode are ones that can provide their own INIT or setup strings and/or issue AT commands.

Note: Crcuit-switched configuration requires a voice plan (account) with your car-rier, not a 1xRTT data plan. 1xRTT features are not compatible with the circuit switch configuration. Voice plan speeds are generally lower than those of a data plan. It is generally not easy to switch from one plan to the other.

The INIT STATE is a state where the modem will initialize itself by using a single pre-determined concatenated Auto-INIT command string. In some models of the Redwing, the Auto-INIT is actu-ally an AT command itself, called +ATINIT. Since the Auto-INIT takes the shape of traditional INIT strings, those with experience setting up conventional land-line modems should find this fairly easy to configure.

To configure the modem for circuit-switch communication, you will need to use AT commands (page 22). You will need to use direct serial communication to enter the commands for the Red-wing

Different models of the respond to some of the AT commands in different ways, a command which is used with one model may not be applicable to another.

The model number of your modem is on the label on the top of the case (example, Redwing CDMA C3110).

AT Commands and command string

Common AT Commands E Echo Q Quiet Mode &C DCD Control &D DTR Options &S DSR Options S0 Auto-answer mode S7 Wait for Carrier S8 Comma Pause Time S9 Carrier Detect Response Time +IFC=x,x Enable or Disable Flow control - RTS/CTS (for C3110, you will need to use a comma replacement command).$QCVAD Answer as a Data Call for C3110, .+CICB Answer as a Data Call for C3111, .

Commands Specific to the Redwing C3110

There are two primary commands for setting a modem for Auto-INIT. Both commands must be entered in this order for the modem to initialize.

AT+ATINITSTATE=1 AT+ATINIT=string,C[,break][,comma]

The command string cannot contain any spaces, commas, the plus (+) symbol, or a semi-colon (;). If an AT command needed for the string contains a plus or comma (for example, +IFC=0,0), you will need to designate a break character since you cannot use the standard break of ; for the plus to be read and a replacement for the comma. The break and comma designations need to be at the end of the ATINIT command and separated with commas. During the INIT sequence, the modem looks at the entire command before executing the AT command string. If there are replacement values, it will perform the appropriate replacement before executing the AT command.

Example: AT+ATINIT=&C1S0=1$QCVAD=4%+IFC=0^0,C,%,^

The “%” will allow the “+” to be used and the “^” will translate to a “,”. The AT command exe-cuted would be:

Example of executed command: AT&C1S0=1$QCVAD=4+IFC=0,0

Each modem requires a command string that is a combination of AT commands limited to a maximum of 40 characters. The command string will vary depending on the needs of the connected device (for example, some devices need DTR to be high while others need DTR to be ignored). For a full listing as well as parameters and defaults, refer the AT Command appendix starting on page 22.

Examples below. ,CStores the command to NVRAM. [,break] Optional “BREAK” character to allow the use of a command with a “+”. In the example, a “%” is used. [,comma]Optional comma replacement character to allow the use of a command requiring a comma. In the example, a ^ is used.


Redwin


Conmmands specific to the Redwing C3111

The Redwing C3111 does not use “+ATINITSTATE” or “+ATINT”.

To configure the Redwing C3111, AT commands can be concatenated to create a string with “;AT&W” as the last commands to write them into memory.

Some commands, such as “+IFC”, will need to be prefixed with “;AT”.

Step by Step Configuration for the Redwing

The first thing you need to do is determine the model number of your modem. Different model numbers will have different configurations. Some of the configuration steps for one model will not work at all with any other model number.

The model number for your modem is on the sticker which is on the top of the modem (example, Redwing CDMA C3110, or Redwing CDMA C3111, or ). The first letter and number (C3 or ) idi-cates the communication technology your modem uses. The next number (2) indicates the modem model (Redwing). The final two numbers (10, or 11, or 16) indicate the internal hardware model.

Information Required 1. Master Subsidy Lock (MSL) - also called the Unlock Code or Activation Code. This should

be provided by Sprint. The incorrect MSL can cause the configuration to fail. This might also be programmed for you as part of the Setup Wizard activation process.

2. MIN and MDN or MSID - The phone number for your cellular account (also called the MIN). You may have two phone numbers for your modem, the MIN and MSN or MSID. If you have two numbers which are different and you only enter one, the configuration will fail. The MIN and MSN or MSID (if it is different) should be provided by Sprint.

3. Username (SID or NID) and Password - You may also need a user name and password for your account. The user name for your account may be the same as your MIN. The user name and password should be provided by Sprint

Testing the Redwing Configuration
Once the modem has been activated and you’ve built the command string it is recommended that the Redwing modem be tested previous to field installation.

• Dial the Redwing modem telephone number from a land line and verify that the modem auto-matically answers the call with modem tones.

• This test should be completed with the serial cable disconnected to verify that no signaling is required by the modem.

Commission the Redwing Modem on Site (C3110)

The following steps represent a guideline and makes assumptions that the modem has been verified previously in a controlled environment.

1. Install the Redwing modem verifying that all power and antenna cables are correctly secured. 2. Verify that the Redwing modem powers up and the Net light is lit.3. Connect the Redwing modem to the laptop computer via a straight through RS232 cable or con-

nect the serial cable from the modem to a USB to serial device that has been previously installed on the laptop.

4. Using a terminal emulation program (HyperTerminal) set up for 9600bps, 8 data bits, no parity and 1 stop bit issue an AT!RSSI?. This will respond back with a signal strength measurement represented in dBm. The value must be better than -100dBm for the modem to function and it is strongly recommended that -90dBm or better be used as a minimum value.

5. Remove the connection to the Laptop PC and connect your equipment to the Redwing Modem.6. Configure your equipment with the AT command string you created above.7. Have the actual application call your equipment via the modem telephone number and verify

communications.

CHAPTER 4 Hardware Installation

Redwin

Your AirLink Redwing should be mounted in a position that allows easy access for the cables so they are not bent or constricted. The LEDs on the front panel should be visible for ease of opera-tional verification. You should ensure that there is adequate airflow around the modem but that it is kept free from direct exposure to the elements (sun, rain, etc.)

An optional accessory for your Redwing is a mounting kit. The bracket is designed to snugly cra-dle the modem and hold it in place where you need it. See “Mounting Kit” on page 37.

Modem placement with diagrams of the mounting bracket can be found in the Appendix, “Modem Placement” on page 17.

FIGURE 1. Redwing connecters

Connecting the Antenna

Antennas selected should not exceed a maximum gain of 5 dBi under standard installation config-uration. In more complex installations (such as those requiring long lengths of cable and/or multi-ple connections), it’s imperative that the installer follow maximum dBi gain guidelines in accordance with the FFC’s regulations.

Your AirLink Redwing will work with most Dual-Band PCS cellular antennas with a TNC con-nector that works in the high and low frequencies of CDMA . Connect the antenna or RF cable directly to the antenna connector on the back of the Redwing.

Connecting Power


Redwin

Hardware Installation

Your Redwing can be used with either DC (available in most automobiles) or 110 AC (standard US wall power) with the appropriate power adapter (available from AirLink).

The power cable positive lead should be connected to the battery or power source positive termi-nal. The power cable negative lead should be connected to the battery or power source negative ter-minal. The Redwing has an internal polysilicon circuit breaker that opens at 0.5 to 1.0 amps of current.

When your Redwing is connected to power and an antenna, there is a specific pattern to the lights to indicate its operation mode.

Note: When using a DC power source (such as a car battery or solar cell), AirLink recommends placing a fuse (1-2 Amp) on the line close to the power source to pro-tect your power source from possible surges due to shorts or other line issues.

Connecting the Redwing to a computer or other device

Your Redwing’s serial port can be connected directly to most computers or other devices using a standard straight through cable. If you have a DCE device, you will need a null modem or null modem cable.

Your Redwing can also be connected to a USB to serial device connected to a computer or other device which does not have an available serial port but does have USB.

Redwing Indicator Lights

FIGURE 2. Redwing indicator lights

Net (network) - Indicates when there is traffic on the network.

Pwr (power) - Indicates the power adapter is connected and there is power getting to the modem.

The Reset button performs the same function as unplugging power from the modem and plugging it back in. Reset will not alter any saved configuration settings.


APPENDIX 5 Modem Placement

Redwin

When decided on a location to install your Redwing, make sure the modem will be away from direct exposure to the elements (sun, rain, etc.). Excess cables can be bundled and tied with twist-ties or other appropriate binders, but the less the cable is wrapped and bound together, the better the modem will perform.

Optional Mounting Kit

An optional accessory for your modem is a mounting kit. The bracket is designed to snugly cra-dle the modem and hold it in place where you need it.

The Redwing “snaps” into place in the bracket locking into the grooves on the Redwing case. The bracket can be further secured with a twist-tie set into the grooves on the top for situations where the Redwing may be subjected to violent movement, such as in the back of an automobile. In most stationary installations, such as in a field or pipe, the Redwing and bracket shouldn’t require a twist-tie.

The bracket can be attached to the location using #6 screws (mounting hole diameter approxi-mately 0.150").

AT Commands

FIGURE 3. HyperTerminal: Comport Settings

4. Type AT and press Enter. You should get a reply of “OK” or “0”. .5. To see what you are typing as you type it, you will need to turn on the echo and verbose mode.

Type ATE1V1 and press Enter. If you get a reply of “OK”, then you entered the command successfully. If you get a reply of “0” or “ERROR”, try entering the command again.

Using AT Commands with a Terminal Application • The following pages list the AT commands, their parameters, and explain what they do. For

most commands, when you are entering them using a terminal connection, you will need to preface the command with AT (exceptions are noted), i.e. ATA which listed as A

• Some commands have specific parameters while other commands will take whatever you type. • Acceptable parameters and/or specific formats are in the parameters column. • Required variable parameters are denoted with italicized text, example, Dn. The n is variable

and noted in the parameters column. • Optional parameters are denoted with square brackets [ ]. • Most commands with parameters can be entered with ? to read the current value (for example,

AT&D? will respond with “2” if the default has not been changed).• AT Commands are not case sensitive. A capital “E” is the same as a lower-case “e”. • When you are using a terminal connection, if you enter a command which is recognized by the

Redwing, it will respond with “OK”. If the command is not recognized, the response will be “ERROR”.

• Those commands applicable only to certain model numbers of the Redwing will be noted.

• The commands are alphabetical within their groups.

Caution: Symbols listed with commands, such as /, &, or ?, are part of the com-mand and must be included.

AT Commands: CDMA/EVDO

+CTA=n

$QCMIP=n

~NAMLCK=nnnnnn

CDMA/EVDO

This group includes commands specific to CDMA.

Inactivity timer, in seconds.

n=seconds (maximum 20 seconds)

n=0 : Allows the Sprint network to determine the inactivy timer.

Typical network settings cause a link to go dormant after 10 to 20 seconds of inactivity, no packets transmitted or received. This time can be shortened to release the physical RF link sooner when the application only transmits short bursts.

Mobile IP (MIP) Preferences. n=0 : Disabled, SIP only

n=1 : MIP preferred

n=2 : MIP only

On a Mobile IP network, a device connects to the network using PPP. During the negotiation process the Redwing is NOT required to present a username and password to authenticate because the authentication parameters are stored in the modem itself.

Note: Your account with Sprint may not support Mobile IP.

The NAMLCK is the modem's 6-digit OTSL (One Time Subsidy Lock), MSL (Master Subsidy Lock), or SPC (Service Provisioning Code). Sprint will provide the unlock code.

nnnnnn=6 digit unlock code If the number is accepted by the modem, the OK result code is returned. If the number is rejected, the ERROR result is returned. If three successive Errors are returned, the modem must be reset to allow any further attempts.

Caution: The modem permits 99 failures of this command during its lifetime. After that, the modem becomes permanently disabled.

+WSPC=[lock],[nnnnnn]

Service Programming Code. C3111 only.

lock=0 : OTKSL(One Time Key Subsidy Lock)lock=1 : MSL (Master Subsidy Lock)nnnnnn=6 digit unlock code


Redwin


+WMDN=num

Upon successful entry of this code, all other service provisioning AT commands may be used. Generally, Sprint will provide the unlock code and type.

If an OTKSL is used to enter provisioning mode, only the +WIMI, +WMDN, and +WCMT commands will be allowed. All other commands will return ERROR.

Caution: This command supports five attempts to enter the correct service programming code. If five incorrect attempts are performed, the ME will power down.

Note: Once the correct SPC code is entered, the module transitions to the Service Program-ming state. This state is not exited until a commit is done (+WCMT). While in the Service Programming state, subsequent validations of the SPC code are ignored until the Service Programming state is reset.

Set the Mobile Directory Number (MDN). only.

num=phone number

Valid numbers are between 10 and 15 digits in length.

For support of Wireless Number Portability in all non-RUIM software versions, changes to the MDN will update the IMSI_M portion (least significant 10 digits) of the IMSI. Changes to the MDN will also auto-matically update the Access Overload Class values unless specifically modified using the +WAOC com-mand. The new IMSI_M and Access Overload Class values will not be visible in the WIMI and WAOC commands until after the changes are committed with the WCMT command.

Sprint will provide the MDN.

+WIMI=num

Set the IMSI (MIN/MSID preceded by the country code, International Mobile Subscriber Identity). C3111 only.

num=MIN/MSID preceded by the country code

The MIN/MSID preceded by the country code is 15 digits in length; MCC (3), MNC (2), MIN2 (3), MIN1 (7). For support of Wireless Number Portability, changes to this number will NOT update the MDN. Changes will automatically update the Access Overload Class values unless specifically modified using +WAOC command.

Sprint may not support IMSI.

+WSID=[idx],[SID],[NID]

Set SID and NID. C3111 only.

idx=The location in the SID/NID list to store the values. sid=system IDnid=network ID

The new SID/NID values are committed to NV with the +WCMT command (AT+WCMT=1).

A maximum of 20 index locations (0-19) are supported. Error 22 is returned if the specified index value is not in the valid range.


Redwin


Sprint may not support SID/NID.

~NAMVAL=nam[,num,msid,sid,nid]

Write account activation data. C3110 only.

nam=0num=phone number msid=second number sid=0 or the system IDnid=63355 or the network ID

Sprint may not support this function.

Following writing the values, the modem must be reset.

Note: If ~NAMLCK has not been successfully executed, the modem returns ERROR.

2.

Dial-up Networking (DUN) allows a computer or other device to use your Redwing to connect to the Internet or private network using PPP just like an analog modem using a standard phone line.

Microsoft Windows XP is used in the examples below. The modem driver installation and DUN setup and configuration is similar in Microsoft Windows 2000. Examples are not provided here for installing the driver or configuring DUN for any other operating system.

Installing the Modem Driver in Microsoft Windows

Standard installations of Microsoft Windows XP and 2000 include a generic modem driver which will work with your Redwing.

a. Connect the modem to the computer with the DB-9 cable. b. Plug in the AC adapter, connect the antenna(s) and power on the modem.

a. Select Start > Control Panel > Phone and Modem Options (in Classic View).

Note: The Setup Wizard is the preferred method to install a modem driver and con-figure PPP for your modem. Use the instructions here only if you do not have the Setup Wizard available. Using the Setup Wizard, if do not need to activate your modem, you can select just Setup a DUN Connection from the opening menu to install the driver and set up DUN. Follow the instructions in the Quick Start Guide to install DUN with the Setup Wizard.

Caution: To install any driver on your computer, you may need to be logged in as Administrator or have Administrator privileges for your login.

Connect the Redwing.

Install the driver.

Dial-Up Networking (PPP) Configuration for Microsoft Windows

Once you have a driver for the modem installed on your computer, you can set up and configure Dial Up Networking (DUN) to use the modem as your connection to the Internet using PPP.

Before you start, you will need:

• Administrator privileges to the computer you are configuring or access granted by an adminis-trator on the network to add/remove devices to your computer. (Not necessary on Windows 98/ME.)

• A wireless user account, password, and access number (obtained from Sprint). May not be required.

• Windows COM Port and modem set up for a Standard 33600 Modem (see previous section).• No other program running on your computer that is using the same COM port (serial port) con-

figured for your modem.

Power, Antennas, and Signal Strength

RSSI (Received Signal Strength Indication) is a measurement of the strength or intensity, not nec-essarily the quality, of the received signal.

Caution: Solutions should only be performed if you are experiencing the specific problem indicated and have the specific modem model number indicated. Some solutions are very specific to model numbers due to differing internal hardware.

What is RSSI? Why is the RSSI for my Redwing negative?


Redwin

Frequently Asked Questions and Technical Support

The RSSI is measured in dBm which is the power ratio in decibel (dB) of the measured power ref-erenced to one milliwatt (mW). One milliwatt is zero, therefore less than a milliwatt, common and ideal for cellular communication, is expressed as a negative interger.

The optimal range for AirLink modems is an RF Coverage (RSSI value) of -60 to -95. RF coverage between -95 to -105 DBm will often still register, however functionality at this range can be greatly reduced and registration can become difficult. Any devices with an RSSI below -105 DBm will likely fail to register on a regular basis.

When addressing RF coverage ensure the antenna choice is appropriate for the device and frequen-cies required.

Antennas for cellular communication are commonly omni-directional and either dual-band or multi-band. They come in a variety of shapes and mounting confirgurations to suit several differ-ent types of needs.

While AirLink does sell a limited selection of antennas and antenna accessories, these are by no means all that are available or usable with your Redwing. There are several suppliers of cellular accessories with a much wider selection of antennas designed to cater to a broader variety of situa-tions.

Dual-band

Dipole

Dipole is a common antenna type connecting directly to the Redwing and extending out in a single straight wire.

What is the Proper RF Coverage for my Redwing?

Caution: Low RSSI will have a direct affect on the ability to activate (or provision) your Redwing if it relies on over the air activation such as the the C3111and C3116 modems.

What Type of Antenna is Best for my Redwing?

Antennas selected should not exceed a maximum gain of 5 dBi under standard installation config-uration. In more complex installations (such as those requiring long lengths of cable and/or multi-ple connections), it’s imperative that the installer follow maximum dBi gain guidelines in accordance with the FFC’s, regulations.

For cellular communication, the Redwing requires a dual band antenna supporting both 800 MHz and 1900 MHz (1.9 Ghz) bands.

Caution: Single band antennas, such as those formerly used with a CDPD device, generally only support 800 MHz. Using a single band antenna can greatly reduce your ability to activate or use your Redwing with Sprint.


Redwin


The short dipole antenna (also known as a “rubber duck”) is a good desktop, portable antenna for use in areas with good signal strength and low electrical interference.

Mounts Antennas can be mounted in a variety of ways (magnet, permanent, suction to a window, sticky tape, etc) which can allow you to move the antenna away from the Redwing with a coax cable between the modem and the antenna allowing the antenna to be placed in a more suitable location for proper cellular reception: outside of a metal cabinet, the trunk lid of a car, a window, etc. A mounted antenna can be placed in locations where the simple, short dipole antenna connected directly to the Redwing may not perform at all.

Your Redwing is designed to work either with DC (commonly used in vehicles) or with an AC adapter (standard wall outlet in the US, Canada, and most other countries). The input voltage is 9VDC to 28VDC with an input current from 90mA to 350 mA.

If the modem is provided an inadequate power supply the following symptoms might be experi-enced:

• Modem will constantly power cycle while attempting to register• Modem will register but will power cycle when data is transmitted/received• Modem won’t power on at all.

If these symptoms occur, verify the power supply meets the above mentioned criteria. If an AC adapter is being used; verify it is intended for the AirLink product in question.

It is possible to use a portable battery for your AirLink modem, however, you most likely need to make the connector from the battery to the modem yourself. The battery also needs to have enough power to be able to handle the power consumption of the modem.

You can contact AirLink Support for a guide on how to use your AirLink modem with a portable battery.

Note: When using a cable with an antenna, there is a dB loss over the distance of the cable. It is possible to lose the full gain of an antenna while using a long cable to the modem.

What do I need to power my Redwing ?

Caution: If you previously used AirLink CPDP modems, you may have older power supplies that provide inadequate power and will cause the above mentioned symptoms.

Can I use a portable battery to power my Redwing ?


Redwin


The Redwing’s IP Addresses and Local Networking

On Sprint’s network, for security reasons, some accounts set up to be restricted to communication only from other devices on their network, called a Restricted IP or a Private IP. If you had two modems on Sprint’s network, they could communicate, but your computer, not using Sprint as an ISP can’t. You could normally still access the Internet using your Redwing’s restricted or private IP because the modem would use a proxy or gateway on Sprint’s network.

Security for the Redwing

For specific information about the security of Sprint’s network, contact your cellular dealer directly.

Activation (Registering on the Sprint Network)

These problems are frequently caused by account related issues. The problems could involve an incorrectly configured account or incorrectly input/provisioned account information. The best troubleshooting step is to re-provision the Redwing, confirming the account is set up for the proper data plan and modem or simply work with Sprint to create a new account.

Contact AirLink Technical Support for the specific commands for your Redwing and account with Sprint.

Why Can’t I reach my Redwing from the Internet? What is a Restricted or Private IP?

However, if you need to be able to contact your Redwing (or the devices behind it) directly, instead of a Restricted IP (also called Private IP Non-Routable IP), you will need to contact Sprint your cellular provider to get your account changed to an Unrestricted IP (also called Pub-lic IP).

Does CDMA provide any security?

While CDMA technology provides authentication and inherent data protection, it is still recom-mended you use a VPN for additional data communication security.

I’m Having Problems getting my Redwing registered (activated or provisioned) with Sprint, what could be the problem?

I’m having problems using the Setup Wizard to activate my Redwing, can I activate it manually?
