2 Network Connection
The AirLink Raven and PinPoint CDMA modems are capable of providing network
connections for 1xRTT, Circuit Switched and SMS data.
2.1 Internet (TCP/IP) Connections via 1xRTT
When using the AirLink CDMA modems, 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.

following:
Reset
A
ir Lin k
Raven
C
o m m u n ic a t io n s
Note that the RSSI light may be flashing or solid, showing the strength of the signal.
Also the Tx (transmit) and Rx (receive) lights will flash as data is transferred to and
from the modem on the network.

If however the Reg light is not lit, your modem may need to be configured with a
phone number and other parameters. Or if you have service ordered and a phone
number for your modem, you may add these parameters yourself for some carrier
accounts by doing the following:
•
•
•
Connect up to configure the modem as in Section 3.1.
If you are unfamiliar with using AT commands, please review Section 5 first.
Use the following command to go into PassThru mode: AT\APASSTHRU
(see section PassThru Mode). Note that this command may take up to 20
•
•
Enter the Lock code from your provider using AT~NAMLCK (as described
below).
Enter the phone number, System ID and Network ID with the AT~NAMVAL
command (described below). The parameters are saved automatically once
entered.
•
•
The modem must be physically power-cycled to exit this mode. (This is also
the only way to exit PassThru mode.) Press the Reset button on the front of
the modem.
It may be necessary to enter the username and password provided by your
service provider in the *NETUID and *NETPW fields. (See Section Error!
Reference source not found..) Use AT&W to save these settings.
(PassThru mode is not needed for those two parameters.)
The modem should now come online registered.
Note that the activation process is unique for each type of service provided
by each carrier. The specific activation process required for your service
and carrier is provided in a separate document available on
3.2.1.1 Syntax for ~NAMLCK and ~NAMVAL
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).
The NAMLCK is the modem’s 6-digit OTSL (One Time Subsidy Lock), MSL
(Master Subsidy Lock), or SPC (Service Provisioning Code). The carrier
provides this number to you 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.
~NAMLCK
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)

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 <nam> parameter followed by a 0 or 1 will set the active account to be
used.
AT~NAMVAL=0 - Sets NAM 0 as the active account
OK {Response}
Reading the current account information
The query form of the command will report the details of the active account:
AT~NAMVAL?0 - Queries the active account NAM0
NAM: 0
NUM: 8135551212
SID: 0
~NAMVAL
(10 digit phone number)
(System ID)
NID: 65535
(Network ID)
OK {Response}
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. Following writing the
values, the modem must be reset.
AT~NAMVAL=<nam>,<num>,<sid>,<nid>
AT~NAMVAL=0,5105551212,0,65535
OK (Response)
3.3 Remote Configuration with Telnet
Once the Raven CDMA modem is online and registered, it can be contacted from a
remote location by a computer with an internet connection. Using a telnet application
(e.g. HyperTerminal), a connection can be made to the modem and then AT

IP addresses. This poses a problem for AirLink customers since they cannot contact
their modems unless their addresses are known. AirLink offers a family of solutions
designed for the different situations existing with our customers. One of the
solutions, an IPManager System that implements a wireless Dynamic Domain Name
Server, DDNS.
IPManager is a system which tracks the current IP address which a modem has been
assigned. The DDNS system consists of three main components. One component is a
task in the modem firmware which issues an update notification to the IPManager
server when the modem is assigned a new IP address. The second component is the
IPManager server which receives IP change notifications from all modems and
updates a DNS server, the third component. It may, optionally, log the latest known
IP address in a database, which may be accessed to see a history of the IP updates.
Customers may then use the wireless Dynamic DNS server to obtain the current IP
of an AirLink modem. The following diagram shows the IPManager system elements.

5.1 IPManager and Dynamic DNS Updates
The IPManager system provides a mechanism to implement a wireless Dynamic DNS
service. If the IPManager settings are configured, the modem will send IP change
notification messages to AirLink IPManager servers. These servers will then
acknowledge the notifications and dynamically update a DNS server, thus allowing
users to access
a
modem by domain name. The *IPMANAGER1 and
*IPMANAGER2 settings can be set to either the domain name or IP address of a
server to notify. The *MODEMNAME setting should be set to the name to prefix to
the domain zone for which the IP Manager server is responsible. For example, if
*MODEMNAME=mymodem and *IPMANAGER1 points to a server responsible
for the eairlink.com domain zone, then the modem’s fully qualified domain name
will be: mymodem.eairlink.com.
To configure your AirLink modem to addressed by name, the modem needs to have 4
elements configured:
1. Modem name
2. Domain
3. IPManager IP Address
4. IPManager update interval
The following illustrates a way to configure an AirLink modem to be addressed by
name:
at*modemname=mymodem
at*domain=eairlink.com
at*ipmanager1=eairlaink.com
at*ipmgrupdate=60 [to update the DNS server at least hourly]
5.2 Using Names in the Modem, Domain Name Resolving
The AirLink modems have an integrated DNS resolver, which uses the DNS entries
specified by the *DNS1, *DNS2, and *DNSUSER settings. This allows the use of
names in the AirLink modems instead of IP addresses.
Both regular and reverse DNS lookups are supported. ATNSLOOKUP command

address
(e.g.
for
return
a name resolution is performed on a name which is not fully qualified (i.e. contains
no dotted portions), the value from *DOMAIN will be concatenated to the end.
Typically the *DNS1 and *DNS2 values will be automatically filled in when a
connection is negotiated with the carrier. The *DNSUSER value is provided to allow
the user to specify a DNS server to check with before resorting to the carrier provided
servers. If *DNSUSER is set to 0.0.0.0, it will be ignored and only the carrier DNS’s
will be consulted. If it is set, the name server at the provided address will be queried
first. If it doesn’t respond (within the timeout period, 10s) or can’t find the requested
entry, the carrier DNS’s will then be queried.
The special domain name “ppp-peer” will always resolve to the address to use to
communicate with the PPP (or SLIP) host peer connected to the host port. If there is
no PPP (or SLIP) peer (i.e. modem is not in PPP or SLIP mode), then “ppp-peer” will
resolve to 0.0.0.0. If, for example, you wanted to report IP address changes to the

6 Serial Communication Modes
In this section the following terminology is used:
This is the computer or terminal that is attached to the serial port of
the Raven. Also known as the DTE.
Host:
Modem:
The Raven. The DCE to the host.
OEM
Modem:
The embedded communications transceiver module.
Server:
A computer to which a Raven is communicating wirelessly.
An AirLink modem 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 is the default.
PPP:
Modem is using PPP to communicate with the Host.
Direct connection to internal OEM Module.
PassThru:
UDP PAD:
Any data received on the serial port is assembled into UDP packets
and send to the session’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:
SLIP:
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.
Modem is using SLIP to communicate with the Host.
The default mode is AT command. If the modem is in any of the other modes, the AT
command mode can be re-entered by:
•
•
Deactivating DTR (if &D2 or Ignore DTR, S211, is not set)
Issuing the +++ escape sequence (if Disable AT Escape, DAE, is
not set)
•
Resetting or Power cycling the modem.
The PassThru mode can only be exited by resetting the modem
The modem can be programmed to enter one of the other modes automatically on
power up. This is done setting the Startup Mode Default (MD) to the desired mode.
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 command can be used before the 5-
second timeout expires.
The modes are described in more detail in the following sections.

Raven and PinPoint CDMA User Guide Version 1.12
6.1 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 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 from the AT mode by using any of the following commands:
ꢀ AT\APPP<CR>
ꢀ ATDT10.0.0.1<CR>
ꢀ ATDT10001<CR>
ꢀ ATD#19788<CR>
ꢀ CLIENT<CR>
In response to any of the preceding commands, the modem will respond with
CONNECT<CR><lf>
and is ready for the host to begin PPP negotiations.
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 network, depending on
the settings of *USEPRIVATEIP [S300]. If *USEPRIVATEIP =1, the value of the
private IP an be determined beforehand by querying S110. The private IP to be used
can be defined with the command AT*PRIVATEIP=192.168.100.33 substituting the
desired IP address.
AirLink Communications, Inc.

Raven and PinPoint CDMA User Guide Version 1.12
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.
If a public IP address is being used, any changes in the IP (as determined by the
wireless network) will result in the PPP link to the host being disconnected,
requiring the host to reinitiate it. The public IP is passed to the host in the PPP
negotiations, so when the network forces a change, the modem has to force the host
to renegotiate the PPP link to make this happen.
The host can exit PPP mode by deactivating DTR (if S211=0 or &D2) or issuing the
+++ escape sequence.
Note that DTR needs to be asserted (or S211=1 or &D0) by the host before PPP mode
can be entered.
6.3 PassThru Mode
In PassThru mode, all serial traffic is sent directly between the internal OEM
Module and the host. In this mode, the modem does not behave normally. This mode
can be used to configure OEM Module-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 OEM Module is established.
Note that some OEM Modules 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 resetting or power-cycling the modem. This mode
cannot be entered via a telnet session.
6.4 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. Note that DTR needs to be asserted (or S211=1 or &D0) by the
host before a UDP session can be entered.
A UDP session is initiated by one of the following events:
•
•
Using the Dial UDP (DP) AT command (as in ATDP192.168.3.23/3456)
Setting the Startup Mode Default (MD) to 3 (UDP) so that a UDP session is
entered automatically when the modem powers up. Serial data will be sent to the
IP/port specified in S53.
•
An incoming UDP packet is received and
-
-
-
-
UDP auto answer is enabled (S82=2)
The destination IP address matches that in S53
Or allow any IP is set (AIP=1)
The modem is in AT mode [not in a current UDP or TCP session]

Raven and PinPoint CDMA User Guide Version 1.12
UDP packet assembly is affected by the values of S50 (PAD Forwarding Timeout)
and S51 (PAD Forwarding Character). Data received in the serial buffer will be
transmitted when the idle inter-character timeout specified in S50 (in tenths of
seconds) occurs or when a character is received that matches S51 (if non-zero).
The host can exit UDP mode by deactivating DTR (if S211=0 or &D2) or by issuing
the +++ escape sequence.
6.4.1 UDP Auto Answer
UDP auto answer (previously called UDP half-open) is set with S82=2. When set,
the modem will automatically establish a UDP session to the source IP address and
port of the UDP packet received. The modem will remain “locked” to this one remote
IP/port until no data is sent or received for the time interval defined in the UDP auto
answer timeout (S83). During this session, packets from other IP/port addresses will
be rejected, unless *UALL is set. Whether or not an incoming packet will cause the
modem to enter a UDP session is always dependent on the S53 and AIP settings.
When idle, after the timeout has occurred, the modem is in AT command mode on the
serial port, and any valid AT command may be entered during this time.
The Normal UDP Mode (MD3) can be combined with UDP auto answer to cause
the incoming serial data to be sent in UDP packets (instead of being treated as AT
commands), while allowing sessions to be established from different UDP sources. A
UDP session will be initiated either by incoming serial data or by an incoming UDP
packet. The session, started by either method, will be terminated when no data has
been sent or received for the S82 period. Once the session terminates, another may
be initiated by either means.
When the session is initiated by serial data, the new session will be established using
the destination address specified in S53. The S53 setting can be changed if the
connect to last UDP setting (*UDPLAST=1) is set. The address in S53 will be
updated to reflect the address of the last session initiated by an incoming UDP
packet. So that when new data is received over the host serial port while in the idle
state, a session will be re-established with the last address. (This behavior is the
same as the previous Hybrid2 (MD6) mode).
Note that TCP auto answer (S0=[1|2]) may also be set simultaneously with UDP
auto answer. Then, when in the idle state, the modem will accept either a TCP or
UDP incoming packet, and enter a TCP or UDP session as appropriate.
6.4.2 Reliable UDP
Reliable UDP adds a simple protocol on top of UDP to provide reliable deliver of data.
When data is received from the host serial port, a 2 byte header is added to the data,
containing a message type and a sequence number. The modem will continue to send
this data (buffering any received data in the meantime) until it receives an
acknowledgement with this sequence number. If an acknowledgement is not received
within the timeout period (specified in S7), the data will be retransmitted. This will
continue until an acknowledgement is received or the modem is reset. Likewise any
UDP packets received by the modem are expected to have this simple header. The
modem will issue an acknowledgement for any valid packets which are received.
Configure the modem as for a normal UDP session. Set the Startup Mode Default
to 3, and the UDP Mode Default to 7 [ATMD73]. If using two modems, configure
the Destination IP and Port in each to point to each other. Serial data will then be
sent reliably between the two

Raven and PinPoint CDMA User Guide Version 1.12
Although it adds reliability, the simple implementation of the Reliable UDP mode in
the modem does not check for duplicate packets.
6.4.3 Multicast UDP [Raven Only Feature]
Multicast UDP results in any data received from the host serial port being sent to all
the clients in the Modbus list. The remote port number is taken from S53. To avoid
flooding the network, the packets are sent to each client with a 20ms pause in
between. The receipt of UDP packets works as in normal UDP mode (i.e. bound by
the value S53 and/or AIP). Since it may take a while to transmit the data to all hosts
(especially if all 20 Modbus entries are used and name resolutions are required), new
data received from the host port is buffered until current transmissions to all hosts
are finished.
Enter the list of target IPs in the Modbus IP list. The index numbers in the IP list
aren't used. Configure the Raven as for a normal UDP session. Set the Startup
Mode Default to 3, and the UDP Mode Default to 8 [ATMD83]. Configure the
Destination port to match the device port of the remote modems.
6.5 TCP PAD Mode
When the modem is in a TCP session, all characters received on the serial port are
assembled into TCP packets and sent to the mode’s remote IP address/port, and any
packets received from the remote end of the TCP connection are disassembled and
dumped onto the serial line. Note that DTR needs to be asserted (or S211=1 or &D0)
by the host before a TCP session can be entered.
A TCP connection is established by one of the following methods:
•
•
Using the Dial TCP (DT) AT command (as in, ATDT192.168.3.23/3456)
TCP auto answer is enabled (S0=1|2), a TCP connection request is received, and
the modem is not in a data session.
•
Data is received on the serial port and
-
-
The Startup Mode Default (MD) is 4 (auto TCP)
The remote TCP destination, as defined in S53, successfully responds to the
TCP connection request.
The value of S7 (TCP Connection Timeout) specifies the number of seconds to wait,
after initiating a TCP connection attempt, for a successful connection to be
established. If the connection has not been successfully established before the
timeout occurs, ERROR/BUSYis returned.
TCP packet assembly is affected by the values of S50 (PAD Forwarding Timeout) and
S51 (PAD Forwarding Character). Data received in the serial buffer will be
transmitted when the idle inter-character timeout specified in S50 (in tenths of
seconds) occurs or when a character is received that matches S51 (if non-zero).

Raven and PinPoint CDMA User Guide Version 1.12
The TCP session will be terminated if no data is transmitted or received for the time
interval specified in TCPT and TCPS. TCPT is the number of minutes [TCPS=0] or
seconds [TCPS=1] used for this idle timeout.
TCPT should never be 0 when using the TCP mode. A broken TCP session can
result in the modem being left with a TCP half-open connection that can only be
terminated with a reset.
The host can also terminate a TCP session by deactivating DTR (if S211=0 or &D2)
or issuing the +++ escape sequence.
Note that DTR needs to be asserted (or S211=1 or &D0) by the host before a TCP
session can be started.
6.6 TCP Auto Answer
TCP auto answer (S0=1|2) also allows a TCP connection request to be “answered”
when the modem is idle, not in a data session. Note that DTR needs to be asserted (or
S211=1 or &D0) by the host before a TCP session can be entered. The TCP
connection request’s destination port has to match the modem’s device port.
Note that UDP auto answer may also be set simultaneously with TCP auto
answer. Then, when in the idle state, the modem will accept either a TCP
connection request or UDP incoming packet, and enter a TCP or UDP session as
appropriate.
6.7 Hybrid Modes
Some previous hybrid modes (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.

6.8 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 &D2) or issuing the
+++ AT escape sequence.
Note that DTR needs to be asserted (or S211=1 or &D0) by the host before SLIP
mode can be entered.
6.9 Modbus/BSAP Configuration [Raven Only Feature]
Modbus, BSAP, and Modbus variations are communications protocols that are widely
used in telemetry. They were designed to be used in a radio environment where
packets are broadcast to a group of remote units. Each Modbus packet contains an ID
so that only the one remote unit, whose ID matches the ID in the packet, will respond
to the host. The ID is used to address a specific remote.
When Ravens are used in place of radios, there is a Raven connected to the host
computer and a Raven connected to each remote unit. Packets transmitted from the
host need to contain the IP address of the specific remote unit whose ID matches the
ID in the packet from the host computer.
The Modbus/BSAP feature adds the capability for a list of IP addresses or names,
and matching remote IDs to be entered into the host Raven. When the host computer
sends a poll request, the ID is matched to the corresponding IP address and a UDP
packet is assembled using this IP address. The complete packet from the host is then
encapsulated in this UDP packet and transmitted to the remote unit. The remote
units operate in normal UDP mode and their data is sent to the host.
6.10 Configuring the Polling Host Application Raven
Set the S53 Port to match whatever port number is being used on all the remote
modems. For example, if the remote Ravens’ S110 port number being used is
"12345", then the Modbus host Raven’s S53 port should be set to “12345”.
ATMD13
ATMD23
ATMD33

Variable Modbus [where you set up the individual parameters]
Enter the list of ID/Local addresses and their associated remote IP addresses or
names as follows:
The ID/Local address and IP or name is entered using the ATMLIST or ATMLISTX
commands. ATMLIST allows the ID to be entered in decimal, while ATMLISTX
allows the ID to be entered in hex.
For example, if a remote's IP address is 123.456.133.45 or name is remote1, and its
ID/Local address is 27, you can enter:
ATMLIST27=123.456.133.45
If you want to enter the ID is hex:

ATMLISTX1B=123.456.133.45
Continue until all the remotes are entered. There can be a total of 20 remote ID/Local
addresses entered into a Raven. Note a special build Raven Modbus Host version is
available that allows up to 100 entries in the list.
Remember to save the entries with AT&W.
If Using Dynamic IPs
The host Raven should be configured to report its current IP to a DDNS server so the
remote Ravens can use DDNS to obtain the host Raven’s IP. The remote Ravens can
then send their current IPs to the host Raven which will update the Modbus IP list
by matching the modem names.
Enter names into the IP list as follows:
ATMLIST27=remote1
or ATMLISTX1B=remote1
Continue until all the remotes are entered. There can be a total of 20 remote ID/Local
addresses entered into a Raven. Note a special build Raven Modbus Host version is
available that allows up to 100 entries in the list.
Remember to save the entries with AT&W.
Configuring the Remote Ravens
The remote Ravens connected to the RTUs being polled, need to be set up for normal
UDP operation.
ATMD3
for Normal UDP operation
For Static IPs
Set ATS53= IP address/port number of the Raven connected to the Polling Host. If
the polling host Raven’s IP and port are 123.456.133.11 and 12345, set as follows:
ATS53=123.456.133.11/12345
ATS53=home1/12345
If Using Dynamic IPs
Set ATS53= name/port number of the host Raven. If the polling host Raven’s
*MODEMNAME and Device Port are home1 and 12345, set as follows:
ATS53=home1/12345
The remote Ravens need to be configured to update the host Raven with their current
IPs. Set up *IPMANAGER[1|2] to point to the host Raven:
*IPMANAGER[1|2]=home1
where home1 = *MODEMNAME in the host Raven.
*DOMAIN should match the domain of the host Raven. For example, if the DDNS
being used is eairlink.com, then *DOMAIN=eairlink.com. And the fully qualified
domain name the remote Raven would query is home1.eairlink.com.

A new IP update will be sent anytime the remote Raven detects that its IP has
changed. A periodic update is a redundant process that guarantees the host Raven
will be updated in the event the host Raven loses its IP list for any reason or the
remote Raven’s IP is changed or dropped without notification to the remote Raven.
Configure the frequency the IP update will be occur.
AT*IPMGRUPDATE[1|2]=n
where n = minutes [0-255]
Other parameters may need to be changed, but this is dependent on the RTU type
being used.
Remember to save your configuration with AT&W.
7 PinPoint Notes
7.1 Low-power Mode
A PinPoint 9612 can be configured to enter a low power mode in order to conserve a
vehicle’s battery life. 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). For now see the PinPoint 9612 CDPD User Manual.
Important: the external DB9’s RTS and DTR pins can be configured through ATS to
be used as digital inputs. If one or both pins have been configured to be used as
inputs, then low power mode cannot be keyed off of DTR.
7.1.1 Effect on Modem State
Once the transition from powered on to low-power mode starts, the modem will
change state to AT mode. This results in the current mode (e.g. PPP, TCP, etc.) being
gracefully terminated. For the brief period when the modem is preparing for low-
power mode, the modem will remain in AT mode (i.e. won’t auto-answer, ATD will
fail, etc.). Once low-power mode is entered, the modem will then discard any data
received on the host port.
When the modem is woken from low-power mode, the same behavior occurs as upon
power on. The modem starts in AT mode, and then after 5 seconds will enter the
default mode (MD).
7.2 Real-Time Clock Sync
Every hour, the modem will re-sync the internal RTC with the UTC time received
from the GPS satellites;
7.3 Different Local and Remote Report types
A different report type can be specified for local reports (*PPLATSR) than that for
remote reports (*PPGPSR). The type of commands (either RAP or TAIP) which the
PinPoint accepts and the port it listens on depends on the value for *PPGPSR. For
example if *PPGPSR is set to send RAP GPS reports w/date (AT*PPGPSR=12) and
*PPLATSR is set to send TAIP reports (AT*PPLATSR=F0), the PinPoint will accept
AirLink Communications, Inc.

Raven and PinPoint CDMA User Guide Version 1.12
RAP commands on port 17335 and not TAIP commands on port 21000. To accept
TAIP commands, *PPGPSR would have to be set to F0.
7.4 RAP Poll Command
The RAP poll command can be issued by the local client (i.e. PPP/SLIP peer) to force
a new local report to be transmitted in response. If a RAP poll command is not from
the IP of the PPP/SLIP peer (i.e. IP in S110), the poll will be performed normally (i.e.
the response will go to the server at *PPIP).
7.5 TAIP Emulation
The TAIP emulation functionality allows the PinPoint product to operate in a limited
manner with clients which only understand the Trimble ASCII Interface Protocol
(TAIP). TAIP emulation is enabled by setting the GPS report type to F0 (e.g.
AT*PPGPSR=F0 or AT*PPLATSR=F0). Once TAIP emulation is entered, the
PinPoint will listen for TAIP messages on port 21000 and will no longer
handle/generate RAP messages.
The automatic reports will be sent to the server configured with the *PPIP and
*PPPORT AT commands. This behavior is different than standard TAIP since TAIP
will instead simply report to the last client to request automatic reports.
The TAIP emulation will accept the following TAIP message types:
SRM – allows the client to set reporting mode configuration. The report mode
configuration is not stored in non-volatile memory and such should be reset upon a
unit reset. This behavior emulates that specified in TAIP spec.
QRM – reports the reporting mode configuration (returns an RRM message)
SID – allows the client to set the TAIP ID (AT*PPTAIPID can also be used to set
the TAIP ID). The TAIP ID, when set with a SID message, will be written to non-
volatile memory.
QID – reports the TAIP ID (returns an RID message).
DPV – configures automatic reporting of PV (Position/Velocity) reports based on
distance traveled and a maximum time. The delta distance value specified in the
message is converted to hundreds of meters and stored as *PPDIST. The maximum
time interval is stored as *PPTIME and the minimum time is stored as
*PPMINTIME. The epoch value is ignored.
FPV – configures periodic reporting of PV (Position/Velocity) reports. The time
interval from the message is stored at *PPTIME. Currently the epoch value is
ignored.
QPV – responds with a PV (Position/Velocity) report.
The TAIP emulation will generate the following reports corresponding to the
appropriate event (either a query for it, echoed due to a set, or due to an automatic
reporting event):
RRM – reports the reporting mode configuration.
RID – reports the TAIP ID.
RPV – Position/Velocity report.

7.6 NMEA Reports
PinPoints can be configured to output reports containing the NMEA sentences
received from the GPS unit. NMEA reporting is configured by setting the reporting
type (*PPGPSR or *PPLATSR) to E0 or E1. Specifying the report type as E0 will
output the GGA and VTG NMEA sentences, while E1 will output the GGA, RMC,
and VTG NMEA sentences.
If *PPGPSR is set to E0 or E1, the NMEA reports will be sent instead of RAP
reports to the server configured with the *PPIP and *PPPORT AT commands. If
*PPLATSR is set to either E0 or E1, the NMEA reports will be sent to the PPP/SLIP
peer (if one is connected).
If the GPS report type (*PPSGPR) is set other NMEA reports, the PinPoint will still
listen on port 17335 and respond to RAP commands received. This allows the RAP
poll command to be used while in NMEA reporting mode

8 PinPoint Specific AT Commands
These AT commands are specific to the AirLink PinPoint.
Description
Command
DTRP=n [?]
Set or query the DTR power control.
n = 0: Ignore DTR for power control
n = 1: Enter low power mode when DTR is low
n = 2: Enter low power mode when DTR is high
NOTE: Also see PTMR
GPSn
Send NMEA GPS strings out serial link.
ATGPS will cause the NMEA GGA, RMC, and VTG GPS strings to
output to the serial port one time.
ATGPS1 will cause these strings to be sent out the serial link once
per second forever.
ATGPS0 will stop the feed.
PTMR=n [?]
Number of minutes after one of the power down events (VTLG or
DTRP) happens until the PinPoint enters the low power mode.
n = 0-255. If DTRP and VLTG are both 0 (zero), this setting does
nothing.
NOTE 1: There is always a minimum of 1 minute between power
down event and actual shutdown (to give the modem time to
prepare); entering zero will not power down the modem
immediately, but after one minute.
NOTE 2: In the first 5 minutes after modem powers up, power
down events are ignored to give the user time to change
configurations.
VLTG=n [?]
*DTRI=n
Set or query the voltage level at which the PinPoint goes into low
power mode.
n = 0: Ignore voltage for power control
n = low power voltage threshold in tenths of volts.
Example: ATVLTG=130 would power down the modem if the
voltage goes below 13.0V.
Enable monitoring the DTR signal as in input event.
n = 0: Disable DTR input monitoring
n = 1: Enable DTR input monitoring
NOTE: If DTR is used as an input, DTR cannot be used for low-
power control. (See DTRP)

Description
Command
*PPMINTIME=n [?]
Specifies the minimum amount of time between reports generated
due to either the time interval (*PPTIME) or the distance interval
(*PPDIST). This is useful to limit network traffic and make more
efficient use of bandwidth. This can be used in conjunction with
store and forward.
n = number of seconds [0-65535] to wait between sending time or
distance triggered reports. The minimum value which this setting
can take depends on the policies of the carrier. 0 = Disabled.
*PPODOM=0|1[?]
Enable odometer reporting
n = 0 - Odometer reporting is disabled [default]
n = 1 - Odometer reporting is enabled
*PPODOMVAL=n [?]
*PPPORT=n [?]
Set or query the PinPoint’s current odometer value. The value is in
meters. Maximum value is approximately 4.3 billion meters (2.5
million miles).
Port where GPS reports are sent.
Possible value: nnnnn = 1 – 65535
NOTE: Also see ATSIP.
*PPSNF=n [?]
Set or query the GPS report Store and Forward feature.
Store and Forward will cause GPS reports to be stored up if the
PinPoint goes out of network coverage. Once the vehicle is in
coverage the GPS reports will be sent en masse to the server.
n = 0: Disable Store and Forward
n = 1: Enable Store and Forward (default)
*PPSNFB=n [?]
Store and Forward Behavior.
When *PPSNF=1, the type of Store and Forward behavior is
defined by:
n = 0: Normal Store and Forward. Data is stored when the
PinPoint is out of CDPD coverage; when the PinPoint is in
coverage, data is sent to server as soon as possible. This is
the default for PinPoints with RAP version 1.3 or lower.
n = 1: Data sent only when polled. Data is stored until polled using
the Poll command sent by a server.
n = 2: Grouped Reports. Data is stored until the desired minimum
number of reports (see *PPSNFM) has been stored. The
data is then sent to the server in groups with at least the
specified number of reports.
*PPSNFM=n [?]
Store and Forward Minimum Reports.
n = 0 to 255
n specifies the minimum number of reports that must be stored
before they are forwarded to the server. The data is then sent to
the server in packets that contain at least this number of reports.

Description
Command
*PPSNFR=n [?]
Store and Forward Reliability
GPS reports will be retransmitted if not acknowledged by the
server.
n = 0: SnF reliability is disabled
n = 1: SnF reliability is enabled
*PPTAIPID=xxx [?]
*PPTIME=n [?]
Sets/queries the TAIP ID. This ID is returned in TAIP reports if it
has been negotiated with the TAIP client. This value is only used in
conjunction with TAIP emulation mode (*PPGPSR=F0).
xxxx = the 4 character TAIP ID to assign this device.
GPS Report Time Interval
Range n = 1 – 65535 Seconds, 0 = Disabled
NOTE: A report time of less than 30 seconds in a CDMA network,
can possibly keep an RF link up continuously. This will eventually
cause the PinPoint to overheat and shutdown, plus annoy the
CDMA carrier since an RF resource will be tied up to transfer
small amounts of data. The CDMA RF channel will be released and
go dormant in 10-20 seconds of no data sent or received.
NOTE: Some carriers may impose a minimum transmit time.
See *PPMINTIME
NOTE: Also see *PPTSV
NOTE: Also see +CTA [for CDMA}
*PPTSV=n [?]
Timer for Stationary Vehicles.
n = [0--255]: Time interval in minutes that the PinPoint will send
in reports when it is stationary.
For example, if *PPTIME=10, the PinPoint will send in reports at
least every 10 seconds while it is moving; however, once it stops
moving, it will slow the reports down to this *PPTSV value. A zero
value disables the stationary vehicle timing.
*RTSI=n
Enable monitoring the RTS signal as in input event.
n = 0: Disable RTS input monitoring
n = 1: Enable RST input monitoring
NOTE: If RTS is used as an input, hardware flow control cannot be
enabled
*UDPRGPS=n [?]
Set or query GPS stamping of UDP Reliable packets. When set,
data received on the host serial port will be encapsulated with the
GPS date and time.

9 Using AT Commands
Use a terminal emulation program to connect up to the modem either locally (via the
serial port of a computer) or remotely (over an existing internet connection on a PC to
the modem at a remote location). Set up to connect to the modem by either method
described in Section 0.
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 the Enter key.
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:
ATS23=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.
9.1 CDMA Specific AT Commands
These AT commands are specific to the CDMA devices and networks.
Command
Description
Inactivity timer, in seconds. Typical CDMA 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. A good example is a PinPoint that transmits its location reports
periodically. A setting of +CTA=2 will release the link 2 seconds after
transmitting its report.
+CTA=n[?]
Displays the internal temperature of the SB555 module in degrees
Centigrade

9.2 Raven and PinPoint AT Command Reference
Command
+++
Description
AT Escape sequence (not preceded by AT).
If modem is in a data mode, this sequence causes the modem to re-
enter AT command mode. There must be 1 second of idle time on
the serial port before and after the sequence. Note that the “+” is
ASCII character 0x2B.
NOTE: The detection of this sequence is disabled if DAE=1
A/
Re-execute last command.
AIP=n [?]
n = 0: Allow only the IP specified in S53 to connect when UDP auto
answer is enabled (S82=2).
n = 1: Allow any incoming IP to connect when UDP auto answer is
enabled (S82=2).
Always subject to any Friends filters that may be defined
D[method][d.d.d.d][/ppppp]
or
Dial a connection to a remote IP and Port using either UDP, TCP,
or Telnet.
method =
D[method][[@]name][/ppppp]
P – Establish a UDP connection
T – Establish a TCP connection
N – Establish a Telnet connection
d.d.d.d = IP address to establish connection to
name = domain name to establish connection to
ppppp = IP port to establish connection to
Examples:
ATD – Dial (establish) default connection per S53
ATDPnnn.nnn.nnn.nnn[/ppppp] - Dial (establish) UDP session to
the specified IP address/port.
If the method, IP address, or port is omitted, the values from S53
are used. If a telnet connection is requested (N) and the port is not
supplied, port 23 will be used instead of the value from S53.
Several special dialing numbers exist to make it easy to establish a
PPP or SLIP connection with the modem. ATD#19788 or
ATDT#19788 will establish a PPP connection (see \APPP) and
ATDT#7547 will establish a SLIP connection (see \ASLIP).
If a domain name is specified, the ‘@’ symbol can be used to
explicitly indicate the start of the name. For example, if
“ATDPHONY” is issued, this will be interpreted as dial a UDP
connection to ”HONY”. To dial using the default method to host
“PHONY”, one would issue “ATD@PHONY”.
To end the connection, issue the +++ escape sequence or drop the
DTR line (if Ignore DTR S211=0 or &D2)
NOTE: The source port of the session is the Device Port (set by
S110 or *DPORT)

Command
Description
*DOMAIN=[name] [?]
(was *DOMAINSUFFIX)
Domain (or domain zone) which the modem is in. This value is used
during name resolutions if a fully qualified name is not provided
and also for DNS updates. This value can be up to 20 characters
long.
If *DOMAIN=eairlink.com, then when ATDT@remote1 is
entered, the fully qualified name remote1.eairlink.com will be
used to perform a DNS query to resolve the name to an IP address.
Note: Only letters, numbers, hyphen ‘-‘, and periods can be used in
a domain name.
*DPORT=n [?]
*DU=n [?]
Sets or queries the modem’s Device Port. Valid values are 1-65535.
[See S110]
Dial UDP Always
The dial command always uses UDP, even when using ATDT
n = 0: dial using the means specified [default]
n = 1: dial UDP always, even when using ATDT
NOTE: When this parameter is set you cannot establish a TCP
PAD connection.
*ENQ=n [?]
Outputs an ENQ [0x05] after the TCP CONNECT delayed by the
Delay Connect Response time [S221].
n = 0: Disabled (Default).
n = 1: Enables ENQ on CONNECT.
*HOSTPRIVMODE =n [?]
(was S300)
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 *HOSTPRIVIP.
The modem will then perform NAT-like address translation, which
shields the Host from network IP changes.
*HOSTPRIVIP =d.d.d.d [?] Set or query the private IP address that is to be negotiated by the
PPP connection if *HOSTPRIVMODE =1.
(was S301)
*HOSTPEERIP =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.
(was S302)
NOTE: This is not normally used nor needed by user applications.
*IPMANAGERn=[name][?] Sets a domain name or IP address to send IP change notifications
to. Up to two independent IP Manager servers can be set, using
either AT*IPMANAGER1 or AT*IPMANAGER2. Updates to a
server can be disabled by setting that entry to nothing (i.e.
“AT*IPMANAGER1=”).

AT*IPMGRKEY1 is used to set the key to use with
AT*IPMANAGER1, while AT*IPMGRKEY2 is used to the key
with AT*IPMANAGER2.
key = 128-bit key in hexadecimal [32 hex characters]
*IPMGRUPDATEn=x [?]
Sets the number of minutes to periodically send an IP update
notification to the corresponding server. This will occur even if the
IP address of the modem doesn’t change. *IPMGRUPDATE1 is
used to set the refresh rate to *IPMANAGER1, while
*IPMGRUPDATE2 is used with *IPMANAGER2.
x = 0, 5-255 minutes. If the value is set to 0, then periodic updates
will not be issued (i.e. IP change notifications will only be sent
when the IP actually changes).

10 Raven Installation
This section details the hardware specs of the Raven and mounting it with other
hardware, the power requirements, mounting bracket, etc.
Mounting the Raven
The Raven should be mounted in a position that allows easy routing and access for
the cables. There should be no binding or sharp corners in the cable routes. The
Raven should be mounted so that the LEDs on the front panel can be easily seen for
ease of operational verification.
The snap-in mounting bracket (part number 100-170-1006) is installed using #8 or
#10 screws. Press the Raven down firmly into the bracket and note that both sides
have locked into the groove on the Raven case.
Figure 1 - Raven Mounted in Mounting Bracket
Note: The tie-wrap is if the modem needs to be really secure, as in a vehicle or in
shipping. In stationary applications, as in a box that sits out in a pasture with a solar
cell, etc., the tie-wrap is not necessary.

11.2 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.

11.3 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.
