Product Overview
About the MultiConnect Cell Modem
The MultiConnect® Cell 100 Series cellular MTC-EV3 modems are ready-to-deploy, standalone dual-band EV-DO
modems that provide wireless data communication. The modems integrate seamlessly with virtually any
application, and are useful for automated applications, such as remote diagnostics and remote monitoring. They
are available with RS-232 or USB connectors. The MultiConnect Cell cellular modems are based on industrystandard open interfaces.
Note: The power-saving switch—which appears with the NORMAL and LOW POWER labels—is included
only on models that have a serial connector.

*Device has been tested up to +85° C. UL Recognized @ 40° C, limited by AC power supply. UL Recognized @ 65° C
when used with the fused DC power cable, part number FPC-532-DC.
Note: The radio’s performance may be affected at the temperature extremes. This is considered normal. There is
no single cause for this function. Rather, it is the result of an interaction of several factors, such as the ambient
temperature, the operating mode and the transmit power.
