Raven II Digital Cellular Modem
1. Introduction
The Raven II is a full-duplex modem, manufactured by AirLink. It supports
telecommunications via a cellular digital packet data (CDPD) network. CDPD
modems are IP based, requiring an internet address assigned by your service
provider.
A PC with Internet access runs LoggerNet or PC208W software to retrieve
data. There must be a CDPD network with coverage at the datalogger site. A
coverage map is provided at
