DM1800-916MB

Preliminary ® Base Station with Host Serial Interface Compatible with RFM miniMESHTM Network Protocol 3 V, Very Low Current Operation Ready-to-Use OEM Module The DM1800-916MB is the 916.50 MHz base station module in the DM1800 family of RF transceivers. The DM1800 family is designed for adding embedded wireless connectivity to a wide range of monitoring and control systems. The DM1800-916MB is equipped with a serial I/O port to interface to a host microcontroller. The module also includes an analog input, a logic input, and a logic output for local monitoring and control. Radio communications range in an “open field” environment is typiwww.DataSheet4U.com cally 200 meters/hop. The DM1800-916MB combines RFM’s very low current ASH radio technology with low power microcontroller technology to achieve long battery life. This module is compatible with RFM’s miniMESHTM network protocol, which provides add-on “plug-and-play” multicast mesh network routing. The DM1800-916MB is certified for operation under FCC 15.249 regulations.
