The RedwingCDPD supported telecommunications between a data logger 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.

Note: The following shows notable compatibility information. It is not a comprehensive list of all compatible or incompatible products.
|CR9000 (retired)||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.|
