Cellular Digital Packet Data (CDPD) network. It is a 3-watt, half-duplex
device operating on a regulated 12 volts @ 2.5 amps, and contains flash

The modem is lightweight (only 12 ounces), with a small form factor
(6.3” x 3.4” x 1.0”). Its rugged construction makes it well suited for
industrial and commercial applications of all kinds.

The present version of the modem comes pre-selected for CDPD V1.1.
This selection can be altered by modifying an Status (S)-Register. Refer
