®
• Field Node with Host Serial Interface
• Compatible with RFM miniMESH^TM Network Protocol
• 3 V, Very Low Current Operation
• Ready-to-Use OEM Module
The DM1800-916MN is the 916.50 MHz field node module in the DM1800 family of RF transceiv-
ers. The DM1800 family is designed for adding embedded wireless connectivity to a wide range of
monitoring and control systems. The DM1800-916MN 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 out-
put for monitoring and control. Radio communications range in an “open field” environment is typi-
cally 200 meters/hop. The DM1800-916MN combines RFM’s very low current ASH radio tech-
nology with low power microcontroller technology to achieve long battery life. This module is com-
patible with RFM’s miniMESH^TM 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.
