The DM1800-434MR is the 433.92 MHz router module in the DM1800 family of RF transceivers.
The DM1800 family is designed for adding embedded wireless connectivity to a wide range of mon-
itoring and control systems. This module is compatible with RFM’s miniMESH
TM
network protocol,
which provides add-on “plug- and-play” multicast mesh network routing. Radio communications
range in an “open field” environment is typically 200 meters/hop. The DM1800-434MR combines
RFM’s very low current ASH radio technology with low power microcontroller technology to achieve
long battery life. The DM1800-434MR is designed for operation under ETSI I-ETS 300 220 regula-
tions.
