The DM1810-434MR-V is the 433.92 MHz router module in the DM1810 family of RF transceivers.
The DM1810 family is designed for adding wireless mesh connectivity to a wide range of monitor-
ing and control systems. This module is compatible with RFM miniMESHTM network protocol, which
provides “plug-and-play” multicast mesh network routing. Radio communications range in an “open
field” environment is typically 600 meters/hop. The DM1810-434MR-V combines RFM’s very low
current ASH radio technology with low power microcontroller technology to achieve long battery life.
The DM1810-434MR-V is certified for operation under ETSI I-ETS 300 220 regulations.
