Page ii December 11, 2002 Redwing CDMA User Guide Version 1.0 Redwing CDMA User Guide WARNING: To satisfy compliance with FCC RF exposure guidelines: All persons must be at least 20 cm from the antenna when the transmitter is operating to meet FCC RF exposure requirements. This module is limited to operate with an antenna having a gain NOT exceeding 2 dBi. 1 Introduction The AirLink CDMA modem is designed to operate in CDMA networks. Two services are available in the CDMA networks: 1xRTT, a packet switched connection, and IS95B, a circuit switched connection. CDMA IS-95B The AirLink CDMA modem is capable of making IS-95 connections. The modem first connects to the CDMA network and the network then connects to the call to either the Public System Telephone Network (PSTN), or to the Internet using QNC. These call types use an Interworking Function (IWF) to bridge the CDMA network to the PSTN. CDMA Network IWF Internet PSTN AirLink Communications, Inc. Page 1 December 11, 2002 Redwing CDMA User Guide Version 1.0 For Internet connections, the Interworking function can use a special feature called QNC (Quick Net Connect). The IWF provides a link to the Internet without going through the PSTN. Establishing a standard point-to-point call requires the Airlink CDMA to configure a modem at the IWF. It is the IWF modem that actually connects to the PSTN and dials the number. Call progress is not directly available to the local modem, although some information can be exchanged. When the IWF has completed the handshake with the remote modem, the local modem is advised and the connection is complete. CDMA2000 1X The AirLink CDMA modem provides data capability into the packet service offered with CDMA2000 1X (1xRTT) technology. CDMA2000 1X offers higher speed data operations than are available with IS-96 service. IS-95 is limited to 14.4 kbps. 1X service uses a fundamental channel at 9600 bps and can add supplemental channels when needed to boost speed to as high as 153.6 kbps on the downlink (network to modem) and 76.8 kbps on the uplink (modem to network). CDMA 1xRTT Network AirLink Communications, Inc. Page 2 Internet December 11, 2002 Redwing CDMA User Guide Version 1.0 2 Product Overview The AirLink Redwing CDMA is a rugged, full duplex 1xRTT CDMA modem that provides wireless transport capabilities for fixed and mobile applications. CDMA is an efficient and secure wireless technology that works well for fixed or mobile applications. The Redwing CDMA is ideally suited for fixed and mobile Industrial or Commercial Applications, including Telemetry, SCADA, Public Safety, Mobile Dispatch, Field Service, Financial Transaction Processing, and Security applications. The CDMA Redwing enables virtually any PC, PDA, or networking device (router, server, etc) to access the CDMA/1xRTT data network. The Redwing CDMA can also be used in installations with many different types of Remote Terminal Units (RTUs), Programmable Logic Controllers (PLC’s) or other computers that perform metering and monitoring functions in the oil, gas, water, and transportation industries. The Redwing CDMA can be a low-cost replacement for many existing landline, private radio and circuit-switched cellular installations. 2.1 Technical Overview 2.1.1 Quick Look: • Support for IS-95 Circuit Switched CDMA, and CDMA2000 1X, and SMS • Dual-band support for both 800 MHz cellular and 1.9 GHz PCS bands • Designed for Industrial Applications (SCADA, Telemetry, Remote Monitoring) • Rugged aluminum case • Compact size 2.1.2 Physical Characteristics: • Weight: • Size: 3” wide x 1” high x 5.1" long • Status LEDs • RF Antenna Connector: 50 Ohm TNC • Serial Interface: RS232 DB-9F < 1 lb. 2.1.3 Power Specifications: • Advanced Power Management features • Low power consumption • Input Voltage: 10 VDC to 28 VDC • Input Current: 20 mA to 350 mA • Typical Receive: 120ma at 12VDC • Typical Transmit: Approximately 120 ma at 12VDC • Dormant connection [idle for 10-20 seconds] 20 ma at 12 VDC AirLink Communications, Inc.

Flow control is released when the temperature falls below 75. Should the temperature of the radio reach 80ºC (176ºF), the modem terminates the connection in order to protect components and avoid drifting outside radio specifications. AirLink Communications, Inc. Page 5 December 11, 2002 Redwing CDMA User Guide Version 1.0 3 Network Connection Options The AirLink CDMA Redwing is capable of offering multiple network connection options. This section will illustrate the different network options that are available. 3.1 Internet (TCP/IP) Connections via 1xRTT When using the Redwing CDMA, remote access to is done via a PPP (TCP/IP) connection to the CDMA network. The CDMA carrier actually provides Internet connectivity, and, therefore, it becomes the ISP for that session. Applications such as web browsing, email, FTP, etc should work as they would normally. CDMA 1xRTT Network Internet Corporate LAN NOTE: Connections to Internet are provided by carrier. Corporate network connections are unique and not provided as part of service. AirLink Communications, Inc. Page 6 December 11, 2002 Redwing CDMA User Guide Version 1.0 3.2 Circuit-Switched CDMA Connections The Redwing CDMA provides traditional Circuit-Switched ‘dial-up’ communications. Where you would normally use a landline modem or analog cellular dial-up device, the Redwing CDMA can be a drop-in replacement. The CDMA carrier actually provides basic connectivity to the Public Switched Telephone Network (PSTN), so all that is needed is a CDMA activation (phone number) and connection of the serial cable. For connection to Windows computers, follow the setup profile for a Hayes Compatible or Standard 33600 baud modem. No special drivers or setup is required.

The connection uses PPP to communicate to the modem and gain access the Internet. It is assumed that you have administrator privileges on the machine that you’re configuring. Before you start, you need the following: Administrator privileges to the computer you are configuring or access granted by an administrator on the network to add/remove devices to your computer. A 1xRTT user account, password, and access number (obtained from your CDMA Service Provider). Windows COM Port and modem set up for a Standard 33600 Modem (See previous sections) No other program is to be running that is using the serial (COM) port that your modem is attached to. NOTE: If you have an existing LAN connection, then this dial-up connection to your CDMA modem may interfere with your existing connection. Once the connection is initiated it will take over as the "default route" for the majority of your LAN traffic, specifically Internet access. It's recommended to disconnect your LAN connection before using a PPP connection with your AirLink modem. If however you want the two connections to co-exist, you can de-select "Use default gateway on remote network" (described later) and you can use the route command to setup routing through the modem properly. Go to a Command Prompt and type route /? to find out more, or talk to your administrator. Now that the modem has been added, the Dial-up connection must be created.

AirLink Communications, Inc. Page 20 December 11, 2002 Redwing CDMA User Guide Version 1.0 4.5 Verifying 1xRTT Connection throughput This section shows what to expect when transferring data over a 1xRTT connection. This test was done using WS-FTP for a BINARY file transfer from Windows 2000 to an Internet hosted FTP server. Data transfers will start at varying speeds, and may climb or fall based on network load and packet latency. This example shows a high throughput, ranging from 72 Kbps to 97 Kbps. Nominal speeds will most likely be between 40Kbps and 60Kbps. Actual throughput will vary depending on geographic region, time of day, and network capacity – as well as the type of applications being used and whether data compression is being used. AirLink Communications, Inc. Page 21 December 11, 2002 Redwing CDMA User Guide Version 1.0 Overall throughput can be determined based upon the size of the file being transferred and the time taken to complete the transfer. In this example, the file transfer of an 8.8 MB file took just under 16 minutes. The Overall throughput was calculated at 93.66 Kbps. AirLink Communications, Inc. Page 22 December 11, 2002 Redwing CDMA User Guide Version 1.0 5 Using AT Commands This document is a quick reference for using AT commands with the AirLink Redwing CDMA modems. Terminal Emulation - To communicate with the modem using AT commands, you need to have an ASCII terminal emulation program running on a PC (default in Windows is HyperTerminal). If you use HyperTerminal, set it to "Direct to COMx" (where x is the COM port the modem is connected to by serial cable), instead of using a specific modem driver like "AirLink CDMA Modem" or "Standard 9600 modem." The terminal emulation program should be configured to operate at 115000 baud, 8 data bits, no parity, and one stop bit (115000, 8N1), and use Hardware Flow Control. Power On - With the cable connected and the terminal emulation configured, power the modem on. The ON LED should illuminate. On the terminal emulation screen, you should see a some characters appear. Send the modem a generic AT command to see if it is responding properly. (See next item for details). Sample AT Commands Here is an example of entering AT commands, changing some settings, saving and resetting the modem. (Note that any command you are unsure of is explained in The AT Commands section.) Type AT and press Enter. AT You should get a response of "0" or "OK". To turn on echo and verbose modes, type the following: ATE1V1 You should see an "OK" response if Verbose Mode was properly activated (V1) If you should see a “0” response, your modem is in Terse Mode and the V1 command did not adhere. Try ATV1 again by itself if that happens. You should see an “OK” response now. To set the baud rate slower, (like AT+IPR=115200,8N1 You should get an "OK" (if in Verbose Mode) AirLink Communications, Inc. Page 1 115200), type the following: December 11, 2002 Redwing CDMA User Guide Version 1.0 Note: HyperTerm needs to be disconnected and reconnected after each baud rate change to have it take effect. AirLink Communications, Inc. Page 2 December 11, 2002 Redwing CDMA User Guide Version 1.0 5.1 Account Activation Commands Command Description NAMLCK = “NAM Lock”The NAM is the “Number Assignment Module”. The NAMLCK command unlocks the ability to set the NAM parameters (to provision a an account). ~NAMLCK The NAMLCK is the modem’s 6-digit OTSL (One Time Subsidy Lock), MSL (Master Subsidy Lock), or SPC (Service Provisioning Code). This number is provided to you by the carrier at time of service activation. 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. Note: The modem permits 99 failures of this command during its lifetime. After that, the modem becomes permanently disabled. AT Command Format: AT~NAMLCK=nnnnnn {Input} (nnnnnn = Lock Code from carrier) OK {Response} AirLink Communications, Inc. Page 3 December 11, 2002 Redwing CDMA User Guide Version 1.0 NAMVAL = “NAM Value” The NAMVAL command has (3) functions: Setting the Active Account index The modem supports two accounts. One is always the ‘active’ account. Using the parameter followed by a 0 or 1 will set the active account to be used. Reading the current account information The query form of the command will report the details of the active account: ~NAMVAL Write account activation data Following successful unlocking by ~NAMLCK, this command can be used with all parameters to write the account data to the modem. If ~NAMLCK has not been successfully executed, the modem returns ERROR. The carrier will tell you what numbers to enter for NUM, SID, and NID. The choice of NAMVAL is up to you. Following writing the values, the modem must be reset. AT Command Formats: 1. AT~NAMVAL=0 (Input) OK {Response} Sets NAM 0 as the active account 2. AT~NAMVAL?0 (Input) - Queries the active account NAM0 NAM: 0 NUM: 8135551212 (10 digit phone number) SID: 0 (System ID) NID: 65535 (Network ID) OK {Response} 3.

The modem has a default setting of 115200. +IPR= +IPR? Other supported rates include: 45, 50, 75, 110, 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600 & 230400 AT Command Format: AT+IPR=n {Input} (n= Fixed Port Rate for the DB9 serial port) OK {Response} AT+IPR? {Input} (Queries the Fixed Port Rate for the DB9 serial port) +IPR: 115200 OK {Response} AirLink Communications, Inc. Page 5 December 11, 2002 Redwing CDMA User Guide Version 1.0 $QCVAD = Answer Data or Fax Sets or reads the mode for answering data/fax calls with A (Answer) or AutoAnswer via S0=1. Values 0 Off. 1 Fax for next call, then revert to data 2 Fax for all calls 3 Async data for next call, then revert to fax Async data for all calls (Default) The CDMA network requires the call type to be negotiated BEFORE the call is answered. This command sets the call negotiation prior to answering. $QCVAD= $QCVAD? NOTE: If connecting modem to a machine (PLC or RTU) for circuit-switched communications, it will be necessary to set the modem to Auto-Answer mode before any call is placed. This can be done by entering the following commands: ATQ1, ATS0=1, AT$QCVAD=4. These can be entered individually or in concatenated format. AT Command Format: (Individual) ATQ1 {Input} (Enable Quiet mode – Suppresses Result Codes) OK {Response} ATQS0=1 {Input} (AutoAnswer On) OK {Response} AT$QCVAD=4 {Input} (Answer Data or Fax Calls) OK {Response} AT Command Format: (Concatenated) ATQ1S0=1$QCVAD=4 (Input) OK (Response) AirLink Communications, Inc.

The escape character is fixed as the plus sign “+” (0x2B). The guard time between normal transmission data and the escape sequence is specified as 1 second and cannot be changed. Therefore, the modem requires a minimum of 1 second of inactivity on the serial input, three plus sign characters, followed by 1 second of inactivity. Repeat Last command (not preceded by AT) Re-executes the last command string entered. The previously executed command remains in the command buffer until AT is entered or the modem is reset or powercycled. This command does not require the AT prefix or a at the end. It executes immediately on entry of the slash character. A/ Answer – Manual Instructs the modem to go off-hook and attempt to establish a connection without waiting for a ring. This is used to answer an incoming call if AutoAnswer (S0) is disabled. The command presumes a RING has been received. If the command is issued without a RING, behavior depends on the state. If in command state, the modem replies with OK and remains in command state. Should the modem be in pass-through state without a call pending, the Answer command is sent to the IWF modem. This typically goes off-hook and looks for carrier. When none is detected, the NO ANSWER or NO CARRIER result is returned. This is, however, dependent on the IWF modem. If the incoming call is a fax call, the modem must be configured for answering fax via $QCVAD and set for fax mode using +FCLASS=2.0 prior to the RING being received by the modem. This is due to the method of call setup on the airlink between the IWF and the CMDA modem. The modem looks for carrier to negotiate the connection, and either issues: • CONNECT and enters data state; or, • NO CARRIER and remains in command state. AirLink Communications, Inc. Page 9 December 11, 2002 Redwing CDMA User Guide Version 1.0 Dial Initiates a data/fax call. (Use +CDV to dial a voice call.) Because of the options available in this command, another AT command cannot follow it on the same line. All characters following the D command are taken as parameter options. Several types of data and fax calls are possible based on the option(s) entered. Packet Data calls Traditional CDMA data call dialing uses the parameter “#19788”. This triggers the modem to try a 1xRTT connection if that service is detected. It is possible that 1xRTT service may be detected in an area that offers 1X voice service, but only IS-95B (QNC) data service. In these situations the call is likely to fail. You can force the modem to attempt one service type or the other by using one of these dedicated parameters: #QNC Connect to QNC using IS-95B service #19788 Connect PPP using 1xRTT service D [options] Async (CSC) Data/Fax The type of call opened depends on the setting of +FCLASS. The modem does not actually dial the number in the string. For an IS-95B call, the dial string is passed to the IWF where a modem there issues the dial over the PSTN. Prior to passing the dial command, the modem sends the IWF modem the string defined in +CFG (Configuration String) to configure the IWF modem for the call. For dialing an async data or fax call, the parameter string options are included on one command line with or without spaces. There is a limit of 35 characters in the dial options string. Upon successful answer and connection, the modem goes into data state. There is a time limit (Register S7 - Wait for Carrier) for the process. The options listed are commonly supported but specific IWF modem capabilities govern the list of supported parameters. Opt Meaning 0 - 9 Any digit (0-9) (*, #, A, B, C, or D are also permitted). The phone number may also include the formatting characters brackets, (), hyphen -, and . These characters are ignored. Tone (DTMF) dialing - ignored by the modem. Pulse dialing - ignored by the modem. Wait for dial tone before processing the remaining characters in the dial string. The duration of the wait is limited by register S7 (Wait for Carrier). Pause before processing the remaining characters in the dial string. The pause time is set by register S8 (Comma Pause Time). Wait for billing (bong) tone before processing balance of string. Wait for quiet answer; limited by register S7 (Wait for Carrier). Hook flash. Causes the modem to go on-hook briefly and then returns to off-hook. This is used to access certain calling features on the PSTN. Result Codes: AirLink Communications, Inc. Page 10 December 11, 2002 Redwing CDMA User Guide Version 1.0 The possible result codes are determined by the call monitoring set by X[n] (Result Code Select). E[n] Echo Controls echoing of characters received from the host (DTE) back to the host when in command state. This also affects framing of responses (see page 33 for details). Value Setting: Disable echo Enable echo (Default) H[0] Hook Control Go ON-Hook to disconnect a data/fax call. (Use +CHV to end a voice call.) If the modem was already on-hook, no change is made. The only parameter allowed is 0 (zero), which is optional. The modem goes from online condition to offline condition.

Page 11 December 11, 2002 Redwing CDMA User Guide Version 1.0 On-line (Remote) Causes the modem to go from command state (online condition) to data state. The modem responds with the normal CONNECT response codes (if enabled) as if the connection were new. This command is executed by the IWF modem. If theCDMA modem was in an offline condition and without an airlink, the NO CARRIER and OK result codes are returned. If the modem was offline and the airlink was established (passthrough state) but without a call in place, the IWF modem attempts to process the command. The typical result is either NO ANSWER or NO CARRIER. This is, however, dependent on the IWF modem. Pulse Dialing This command is provided for compatibility; no action is taken by the modem. Quiet - Result Code Display Option Controls the return or suppression of result codes to the host (DTE). Q[n] Value Setting Disables Quiet mode (enables return of result codes.)

S-Register Set/Query Sets (or queries) the contents of the specified S-register (n) to the new value (x). Zeros are assumed where parameter values are omitted. Var. Range n Valid S-register number (See Table 3-23 on page 103 for values). x as determined by the S-register (n). Result Codes: OK ERROR S-register n set to x. Invalid S-register value (n) or, setting (x) outside of permitted range. Tone - Set DTMF Dialing This command is provided for compatibility reasons; no action is taken by the modem.

Page 12 December 11, 2002 Redwing CDMA User Guide Version 1.0 Verbose - Result Code Form Specifies whether the modem displays the result codes in numeric format or as words (verbose). See Table 3-24 on page 106 for a numerical list of the result codes. Note that numeric codes are returned as ASCII character numerals. V[n] This command also affects framing of responses (see page 33 for details). Value Setting Numeric result codes Verbose result codes (Default) Result Codes: OK(0) n = 0, 1 (The result code is returned in the new setting.) ERROR (4) Otherwise Result Code Select/Call Progress Control Enables tone detection options used in the dialing and handshaking process. As options are chosen, the result codes are also affected. The prime function is to control the modem call response capabilities when the D (Dial) command is issued. Dial tone detection When disabled, the modem waits for the period set in register S6 (Wait for Blind Dial) and blind dials. When enabled, the modem allows five seconds to receive at least 1 second of dial tone. If none is detected then the result code is NO DIAL TONE. X Busy signal detection When disabled, the modem waits for the period set in register S7 (Wait for Carrier). If no connection is made then the result code is NO CARRIER. When enabled, the modem can return the result code BUSY if detected. Values enable (√) or disable (r) tone detection and result codes as indicated in the chart below: Value Dial Tone √ √ Busy Signal √ (Default) √ Profile Restore The modem goes on-hook (drops any active call) and then resets the command and register parameters to the defaults.
