Page 1 February 22, 2003 PinPoint CDMA User Guide WARNING The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter and must not have a gain exceeding 2 dBi 1 Introduction This manual covers information for first-time setup and configuration of your AirLink PinPoint CDMA modem, as well as technical details on this modem. The PinPoint is a combination of a CDMA modem and GPS tracking unit. The CDMA modem allows the PinPoint to report its GPS location to the AirLink Tracking System main console or to custom applications. The modem may be remotely configured to report at different time or distance parameters. The PinPoint is also capable of having its firmware upgraded wirelessly, rendering it unnecessary to physically connect to the modem to upgrade it. 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 IS-95B, a circuit switched connection. The PinPoint CDMA primarily uses 1xRTT connections to transmit and receive data. 1.1 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-95 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).

PinPoint CDMA User Guide Version 1.0 AirLink Communications, Inc. Page 17 February 22, 2003 4 Low-power Mode A PinPoint CDMA can be configured to enter a low power mode in order to conserve a vehicle’s battery. The PinPoint can power down when the voltage to the modem drops below a configured threshold (caused by the vehicle being turned off), or when DTR changes (usually a contact or voltage controlled by the key switch, signaling when the vehicle is turned off). Note that when the PinPoint CDMA is in low power mode, neither the GPS module nor the modem is powered. After a power cycle or reset, the low power controls are ignored for 5 minutes in case the timers are short. The options are set using AT commands. VLTG Voltage Power Policy This setting controls the low voltage threshold used to put the PinPoint into low power mode. It is measured in tenths of a volt. For example, if you want the modem to enter low power mode when the input voltage falls below 13.0 volts, this should be set to: 130 Recommended value: 130 (for 13.0 volts) NOTE: Be VERY careful changing this setting. Ensure the modem is close by when enabling this parameter, because it may power down within 5 minutes. PTMR Powerdown Timer This is the Power down timer. It specifies the length of time in minutes after a DTR event or voltage drops below the threshold, before the modem actually enters the low power mode. If DTRP and VLTG are set to 0, this setting does nothing. Recommended value: 15 (for 15 minutes) Note: There is always a minimum of 1 minute between a power down event and actual shutdown (to give the modem time to prepare), so entering '0' (zero) will not power down the modem immediately, but after one minute. DTRP DTR Power Policy This allows the modems power mode to be controlled by the state of the DTR [Data Terminal Ready] signal. 0 = Ignore this feature. 1 = Low power when DTR is low. 2 = Low power when DTR is high.

Page 18 February 22, 2003 5 PinPoint Vehicle Installation 5.1 Overview Installing a PinPoint in a vehicle consists of: • Choosing a location in the vehicle for the PinPoint • Mounting the PinPoint • Hooking up power to the PinPoint • Routing the cables through the vehicle • Positioning the antennas for good reception • Connecting and securing cables to the PinPoint Note: Keep all cable lengths as short as possible during installation. Route the cables in such a way so they are protected and will not cause interference. Bundle and tie excess amounts if needed. Modem AntennaGPS AntennaPinPoint(not to scale)
PinPoint CDMA User Guide Version 1.0 AirLink Communications, Inc. Page 19 February 22, 2003 5.2 Mounting the PinPoint First locate a place in the vehicle where the PinPoint will go. Make sure the PinPoint will be away from direct exposure to the elements (sun, rain, etc.). Possible locations are: in a trunk where luggage or other items won’t hit it, in the console, or behind the seats in pickup trucks. Ensure the location is secure and will not put the PinPoint in the way of anything. 1. Mount the PinPoint on the provided bracket. 2. Connect the PinPoint’s power cable to a fused 12 or 24 VDC power source. (Note: PinPoint will draw less than 1/2 Amp at 12V.) 3. Mount the CDMA Antenna and route the cable to the PinPoint location. Make sure any excess cable is tie-wrapped and not in the way of any luggage, passengers, or anything else.
PinPoint CDMA User Guide Version 1.0 AirLink Communications, Inc. Page 20 February 22, 2003 5.3 Installing the Antennas There are three options for an antenna: • magnetic roof-mount • through glass-mount • permanent mount 1. Mount the GPS Antenna in the vehicle. The less the cable is wrapped and bound together, the better it will perform. Place it on the roof, or on the dash, or rear panel where it has a good view of the sky (greater than a 90° angle view of the sky -- see Figure 2). GPS ANTENNA Figure 2 – Optimum GPS antenna positioning on a vehicle 2. Connect the GPS Antenna into the PinPoint’s rear panel. 3. Connect the CDMA Cellular Antenna to the PinPoint’s TNC connector. 4. Plug in the power connector into the power receptacle on the PinPoint’s rear panel. Note: The green power light should be on at this point.
PinPoint CDMA User Guide Version 1.0 AirLink Communications, Inc. Page 21 February 22, 2003 6 Using AT Commands This document is a reference for using AT commands with the AirLink PinPoint 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 "Standard 33600 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 <enter>. AT<enter> You should get a response of "0" or "OK". To turn on echo and verbose modes, type the following: ATE1V1<enter> 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 115200), type the following: AT+IPR=115200,8N1<enter> You should get an "OK" (if in Verbose Mode) Note: HyperTerm needs to be disconnected and reconnected after each baud rate change to have it take effect.
PinPoint CDMA User Guide Version 1.0 AirLink Communications, Inc. Page 22 February 22, 2003 6.1 Terminology In this section the following terminology is used: Host: This is the computer or terminal that is attached to the serial port of the PinPoint. Also known as the DTE. Modem: The PinPoint CDMA. The DCE to the host. OEM Modem: The embedded communications module, a Sierra SB555. Server: A computer to which a PinPoint 9612 is communicating wirelessly. 6.2 PinPoint Serial Communication Modes The PinPoint can be in one of six serial communication modes with the attached Host: AT: The modem accepts and responds to standard, Hayes-style AT commands. This mode is the default. PPP: Modem is using PPP to communicate with the Host. PassThru: Direct connection to internal OEM Modem. UDP PAD: Any data received on the serial port is assembled into UDP packets and send to the connection’s associated IP and Port (described later). Any responses received from the associated IP and port destined for the modem’s Device Port are unwrapped and sent out the serial port. TCP PAD: Any data received on the serial port is packaged into TCP messages and sent to the associated connection’s IP and Port (described later). Any data received from the TCP peer is unwrapped and sent out the serial port. SLIP: Modem is using SLIP to communicate with the Host. The default state is AT mode. If the modem is in any of the other modes, AT mode can be re-entered by either deactivating DTR (if Ignore DTR, S211, is not set), issuing the +++ escape sequence (if Disable AT Escape, DAE, is not set), or power cycling the modem. The modem can be programmed to enter one of the other modes automatically on power up. This is done using the Startup Mode Default (MD) AT command. If this setting is non-zero, the modem will enter the specified mode after 5 seconds. If you want to cancel this behavior, the ATMD0 AT command can be used before the 5-second timeout expires. The modes are described in more detail in the following sections.
PinPoint CDMA User Guide Version 1.0 AirLink Communications, Inc. Page 23 February 22, 2003 6.2.1 AT Mode AT commands are used to configure the modem, command it to do something, or query a setting. AT commands must always be terminated by <CR> (ASCII character 0x0D). If E=1 (Echo On), the AT command (including the terminating <CR>) will be output before any responses defined in the next section. Response Framing Two settings affect the format of AT command output: V (Verbose) and Q (Quiet). If Q=1 (Quiet On), no result codes are output whatsoever, so there is no response generated by a (non query) command. If Q=0 (Quiet Off), result codes are output. The format of this output if then affected by the Verbose setting. If Quiet mode is off, the result code is affected as follows: For V=1 (Verbose mode), the textual result code is surrounded by <CR><LF> and any AT query response is also surrounded by <CR><LF>; for V=0, (Terse mode), a numeric result code is output with a single trailing <CR> (no <LF> is output), while any AT query response is followed by <CR><LF> (there is no preceding output). For example, possible output to the AT command “AT<CR>” (assuming quiet mode is not on) is: 0<CR> - if V=0 <CR><LF>OK<CR><LF> - if V=1 6.2.2 PPP Mode In PPP mode, the modem acts as a PPP server, providing an IP address, and DNS servers (if available) to the Host. PPP mode is entered be using the “AT\APPP” command. It can also be entered by issuing a Dial TCP to 10.0.0.1 (e.g. ATDT10.0.0.1) or entering the “CLIENT” command. At this point the modem assumes that the host will start PPP negotiation. The IP received by the host in the resulting negotiation will either be a private (non-routable) IP or a public (network-routable) IP provided by the OEM Modem’s network, depending on the settings of S300. The value of this IP can be determined beforehand by querying S110. Using a private IP insulates the PPP client from changes in IP addresses of the underlying network, as the AirLink modem will perform basic NAT-like address translation on all packets. However, if a public IP address is being used, any changes in the IP (as determined by the underlying communications network) will result in the PPP link to the host being disconnected, requiring the host to reinitiate it. The host can exit PPP mode by deactivating DTR (if S211=0) or issuing the +++ AT escape sequence. Note that DTR needs to be asserted (or S211=1) by the host before PPP mode can be entered.
PinPoint CDMA User Guide Version 1.0 AirLink Communications, Inc. Page 24 February 22, 2003 6.2.3 PassThru Mode In PassThru mode, all serial traffic is sent directly between the internal OEM Modem and the host. In this mode, the AirLink modem does not behave normally. This mode can be used to configure OEM Modem-specific settings (e.g., for provisioning, etc.) Issuing the “AT\APASSTHRU” enters this mode. The modem responds with CONNECT, at which point a direct connection to the modem is established. Note that some OEM Modems requires upwards of 20 seconds before AT commands can be entered, so be patient if there seems to be no response to AT commands. This mode can only be exited by power cycling the modem. 6.2.4 UDP PAD Mode When the modem is in UDP PAD (Packet Assembly and Disassembly) Mode, all characters received on the serial port are assembled into UDP packets and sent to the mode’s remote IP address/port, and any packets received from the same IP/port-destined for the modem’s Device Port (see *DPORT)--are disassembled and dumped onto the serial line. A UDP connection (there isn’t really a connection because UDP is connectionless) is initiated by one of the following methods: • Using the Dial UDP (DP) AT command (e.g., ATDP192.168.3.23/3456); or • Setting the Startup Mode Default (MD) to 3 (UDP) so that UDP mode is entered automatically when the modem powers up. All packets will be sent to the IP/port specified in S53, and you must make sure that the default connect mode in S53 is set to “P” (UDP). • UDP auto answer is enabled (S82=2), an incoming UDP packet is received by an IP address matching that in S53 and/or allow any IP is set (AIP=1), and the modem is in AT mode or isn’t connected while in UDP or TCP modes. UDP packet assembly is affected by the values of S50 (PAD Forwarding Timeout) and S51 (PAD Forwarding Character). S50 specifies (in tenths of seconds) an interval of time for which to collect characters before they are forwarded; S51 (if non-zero) specifies the ASCII code of a character that needs to appear in the data before a packet is sent. The host can exit UDP mode by deactivating DTR (if S211=0) or issuing the +++ AT escape sequence. Note that DTR needs to be asserted (or S211=1) by the host before UDP mode can be entered. 6.2.5 UDP Submodes UDP PAD mode supports the submodes Modbus, Reliable UDP, and Multicast UDP. UDP Auto Answer UDP auto answer (S82=2) is equivalent to what was previously called UDP half-open mode. When set, and in AT mode, it will automatically establish a UDP “connection”
PinPoint CDMA User Guide Version 1.0 AirLink Communications, Inc. Page 25 February 22, 2003 to the IP address (bound by the value S53 and/or AIP) from which a UDP packet was received. This “connection” will be terminated once the UDP auto answer timeout (S83) occurs, and the modem will return to AT mode. This behavior is identical to that in the non-NGE modems. UDP auto answer also now works when in UDP (MD3) and TCP (MD4) modes. If we are in UDP mode, and we don’t have a current “connection”, a new “connection” will be established with the IP address (bound by the value S53 and/or AIP) from which a UDP packet is received. When the UDP auto answer timeout (S83) occurs, the modem returns to a non-connected UDP mode, which allows a new “connection” to be established. Any data that is received from the host port when there is no connection will result in a “connection” being established with the address specified in S53, and any data being forwarded to this address until the UDP auto answer timeout occurs. If the connect to last UDP setting (*UDPLAST=1) is active, the address in S53 will be changed to reflect the address of the last answered “connection” so that when new data is received over the host port in a non-connected state, a “connection” will be re-established with the last address. This behavior is the same as Hybrid2 (MD6) mode. UDP auto answer in TCP (MD4) mode works the same as in UDP (MD3) mode, except instead of returning to non-connected UDP mode when the UDP auto answer timeout occurs, the modem returns to TCP mode. 6.2.6 TCP PAD Mode TCP PAD (Packet Assembly and Disassembly) Mode is similar to UDP, except that a real TCP connection is made to the remote IP/port. A TCP connection is established by one of the following methods: • Using the Dial TCP (DT) AT command (e.g., ATDT192.168.3.23/3456); or • Setting the Startup Mode Default (MD) to 4 (TCP) so that TCP mode is entered automatically when the modem powers up (assuming the remote computer responds to the TCP connection request). All packets will be sent to the IP/port specified in S53, and you must make sure that the default connect mode in S53 is set to “T” (TCP). • TCP auto answer is enabled (S0=1|2), a TCP connection request is received, and the modem is in AT mode or isn’t connected while in UDP or TCP modes. The value of S7 (TCP Connection Timeout) specifies the number of seconds to wait for a successful TCP connection to be established. If a connection has not been successfully established before the timeout occurs, ERROR/BUSY is returned. TCP PAD mode is affected by S50 and S51, like UDP Mode. It is also affected by the values in TCPT and TCPS (serial idle timeout for TCP connection before it’s dropped) The host can exit TCP mode by deactivating DTR (if S211=0) or issuing the +++ AT escape sequence. Note that DTR needs to be asserted (or S211=1) by the host before TCP mode can be entered.
PinPoint CDMA User Guide Version 1.0 AirLink Communications, Inc. Page 26 February 22, 2003 6.2.7 TCP Auto Answer TCP auto answer (S0=1|2) also allows a TCP connection to be “answered” when in UDP mode with UDP auto answer on and there is no current UDP “connection”. This functionality is the same as the answering of a TCP connection while in Hybrid modes. 6.2.8 Hybrid Modes The hybrid modes from the pre-ALEOS days (MD=5, 6) are no longer implemented as special, unique modes. Now that UDP auto answer (UDP half-open, S82=2) can be enabled in conjunction with UDP PAD mode (MD3), effectively this is the same as MD5 and MD6 previously accomplished. Setting MD5 and MD6 are still supported, but not recommended, since all they do is set several settings as described below. The settings to accomplish hybrid modes: AT Setting Hybrid (MD5) Hybrid2 (MD6) MD 3 3 S82 2 2 S0 1 1 *UDPLAST 0 1 6.2.9 SLIP Mode SLIP mode is entered be using the “AT\ASLIP” command. As in PPP Mode, the IP address that the host assumes is affected by the setting of S300. SLIP does not negotiate the IP with the host, so before making a SLIP connection, the host SLIP driver must be configured to use the IP specified by querying S110. The host can exit SLIP mode by deactivating DTR (if S211=0) or issuing the +++ AT escape sequence. Note that DTR needs to be asserted (or S211=1) by the host before SLIP mode can be entered.

S221=n [?] Connect Delay [n = 0 – 255] n = number of seconds to delay the “CONNECT’ response upon establishing a TCP connection OR n = number of tenths of seconds to delay outputting ENQ on the serial port after the CONNECT when the ENQ feature is enabled [see *ENQ] Immediately S300=n [?] Set or query whether a private or public (network) IP is to be used when the Host initiates a PPP connection to the modem. n = 0 [default]: Public (network) IP Mode: When the Host initiates a PPP connection, the host will be given the public IP that was obtained from the OEM Modem. If the network issues a new IP, the PPP connection will be closed (since the IP has changed) and has to be re-initiated. n = 1: Private IP Mode: When the Host initiates a PPP connection, the host will be given the IP address specified in S301. The modem will then perform NAT-like address translation, which shields the Host from network IP changes. S301=d.d.d.d [?] Set or query the private IP address that is to be negotiated by the PPP connection if S300=1. S302=d.d.d.d [?] Set or query the IP address that can be used to directly contact the modem once a PPP connection is established. If this value is not specified, 192.168.13.31 will be used.
