The DM1800-434MB is the 433.92 MHz base station 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 DM1800-434MB 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 typi-

cally 200 meters/hop. The DM1800-434MB 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 miniMESH

TM

network protocol, which provides add-on “plug- and-play” multicast mesh

network routing. The DM1800-434MB is designed for operation under ETSI I-ETS 300 220 regula-

tions.
