REDWINGCDPD Airlink CDPD Cellular Digital Modem


The RedwingCDPD supported telecommunications between a datalogger and a cellular digital packet data (CDPD) network. This CDPD modem was IP based; the cellular provider needed to assign an IP address for the site. The Redwing had many of the same features as its predecessor, the Raven II.

The RedwingCDPD modem was retired 11 March 2004 because of the discontinuation of CDPD services.

Datalogger Considerations

Compatible Contemporary Dataloggers

CR200(X) Series CR800/CR850 CR1000 CR3000 CR5000 CR7X CR9000X

Compatible Retired Dataloggers

CR500 CR510 CR10 CR10X 21X CR23X CR9000

*Although the CR9000X and CR9000 are compatible, the RedwingCDPD does not support their fastest communication rates and therefore is not practical for most of their applications.
