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 IS­95B, 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).

2 Network Connection

The AirLink PinPoint CDMA will be capable of offering multiple network connection
options. As of January 2003, the PinPoint CDMA will only use 1xRTT. Circuit
switched and SMS will follow later.

2.1 Internet (TCP/IP) Connections via 1xRTT

When using the PinPoint 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.

3.2 Windows 2000 PPP Configuration

This section describes how to setup a Windows 2000 Professional Dial-up connection
using an AirLink PinPoint CDMA Modem. The connection uses PPP to communicate
to the modem and gain access the Internet.

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.

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

PTMR
Powerdown Timer

DTRP
DTR Power Policy

Recommended value:

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.

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:

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.

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.

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

GPS Antenna

(not to scale)

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.

AirLink Communications, Inc. Page 18 February 22, 2003

PinPoint CDMA User Guide Version 1.0

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.

AirLink Communications, Inc. Page 19 February 22, 2003

PinPoint CDMA User Guide Version 1.0

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.

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.

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:

Server: A computer to which a PinPoint 9612 is communicating wirelessly.

The embedded communications module, a Sierra SB555.

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 5­second timeout expires.

The modes are described in more detail in the following sections.

AirLink Communications, Inc. Page 22 February 22, 2003

PinPoint CDMA User Guide Version 1.0

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 (non­routable) 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.

AirLink Communications, Inc. Page 23 February 22, 2003

PinPoint CDMA User Guide Version 1.0

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/port­destined 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 non­zero) 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”

AirLink Communications, Inc. Page 24 February 22, 2003

PinPoint CDMA User Guide Version 1.0

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 re­established 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.

AirLink Communications, Inc. Page 25 February 22, 2003

PinPoint CDMA User Guide Version 1.0

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.

A thermistor inside the modem (monitored by the modem CPU firmware) causes flow
control to be activated should the internal temperature reach 75ºC (167ºF) as
measured at the radio. 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.
