Description

The Data Connect cellular based Cellular Data Link series
modem is the latest innovative wireless communication device,
offering a cost effective twoway connection between a central
host computer and remote RTU such as SCADA equipment and
meters over CDMA/1xRTT and GSM/GPRS networks. The
Cellular Data Link device supports RTUs and meters with
RS-232 or RS-485 serial ports at speeds from 1200 to 19200
bps.
The Cellular Data Link modems provides reliability and ease of
installation, making it an ideal low cost alternative to wired
devices for connecting remote devices to host data acquisition
equipment. The embedded TCP/IP protocol stacks support
operation over CDMA/1xRTT and GSM/GPRS data networks.
Operation over circuit switched data (CSD), dynamic IP, and
mobile IP (static IP) modes are all supported.
The Cellular Data Link cellular modems includes a dual-band
CDMA/1xRTT or GSM/GPRS transceiver. Power to the modem
can be a DC voltages source, or when connecting the modem to
an AC power source, a wide range AC to DC power converter
module is included. Standard dual band antenna or external high
gain antenna is supported by a panel-mounted SMA RF
Features:
Dual band 800/1900 Mhz CDMA or GSM/GPRS cellular or PCS frequency band support
Selectable data rates
Support for DTE at 1200, 2400, 9600 and 19200 bps
Selectable EIA RS-232/V.24 (DB-9F & RJ-11C) and RS-485 (RJ-11C) DTE serial port interface supports CSD, dynamic IP, and Mobile IP(static IP) protocols.
