Using the RAVEN II CDPD Modem
Application Note #12

Overview

This Application Note provides information to setup and configure your AirLink CDPD Raven II Modem,
as well as configuration information to setup and configure MultiLogger to communicate with your data
acquisition system using this modem.
CDPD is a technology used to transmit packet data over cellular voice networks. It is ideal for wireless
applications. It is also more cost effective than circuit-switched cellular data for small amounts of data. It
provides instantaneous response for data communications because there are no dialing delays. Built-in
encryption maintains the security of the application data over the air.
The structure of the CDPD network is shown below. The "Application Terminal" would be the data
acquisition unit to which the Raven Modem is connected.
The CDPD Network shown above is accessed via the Internet. The PC running MultiLogger which will be
used to communicate with the data acquisition unit connected to the Raven II must have Internet
access to function. Due to the bandwidth limitations of the Raven II network a dial-up networking
connection is usually adequate for this purpose.
More detailed information on the Raven II Modem can be found in the Airlink Raven CDPD Modem
User's Manual. More detailed information on MultiLogger can be found in the MultiLogger User's
Guide. This documentation is available from the support directory of the Canary Systems website.
Prior to setup of the Modem you will need to obtain a service agreement, the key piece of information
provided by the service agreement is the IP, or the address of the Modem. It is the form of a 4 octet
sequence, in the form nnn.nnn.nnn.nnn, i.e. 166.147.127.200
Contact Airlink at

to obtain information on obtaining a service agreement.
