Although significant delays or losses of data are rare when wireless devices such as the AirLink Communications modem are used in a normal manner with a well-constructed network, the AirLink modem should not be used in situations...
1 Introduction This manual covers information for first-time setup and configuration of your AirLink CDMA modems, as well as technical details on this modem. The modem may be remotely configured. The AirLink modems are also capable of having their firmware upgraded wirelessly, rendering it unnecessary to physically connect to the modem to upgrade it.
1.2 Raven Product Overview The AirLink Raven 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.
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.
Page 12
If the host establishes a PPP link to the AirLink modem, a second PPP link is created between the modem and the host. IP packets can then be sent to and received from the 1xRTT network. If the host device is to send and receive data via the Raven, then the Raven can be configured to used either one of the UDP or TCP packet assembly/disassembly modes.
3 Modem Configuration Modem configuration of the AirLink CDMA modems can be performed using the Wireless Ace application, or a terminal emulation program like HyperTerminal in Windows, or using a telnet application. 3.1 Local Configuration 1. Attach the antennas, DB-9 cable and power to the back of the modem.

(These are the factory default settings for a Raven CDMA modem. If you get garbled characters when typing AT commands, change these settings and reconnect to the modem. For example, change the baud rate to 57,600 bits per second and connect again, etc.) AirLink Communications, Inc. Page 6 March 24, 2004...
8. Type AT followed by [Enter]. You should receive an "OK" in response. 9. Type ATI1 followed by [Enter]. This displays the modem firmware version and you should also see "AirLink Communications, Inc." in it which ensures you are talking to the Raven CDMA modem. (If not, try changing COM ports.)

5 Dynamic IP Addresses Many modern wireless data technologies use dynamic IP addresses rather than static 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.
*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.

*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. AT\APPP<CR> ATDT10.0.0.1<CR> ATDT10001<CR>...
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.
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 AirLink Communications, Inc. Page 31 March 24, 2004...

*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. AirLink Communications, Inc. for Normal UDP operation Page 35...
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. Page 36 March 24, 2004...

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 AirLink Communications, Inc. Page 38 March 24, 2004...
