Description

The DM1800-434MN is the 433.92 MHz field node 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 DM1800-434MN 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 monitoring and control. Radio communications range in an "open field" environment is typically 200 meters/hop. The DM1800-434MN combines RFM's very low current ASH radio technology with low power microcontroller technology to achieve long battery life. DM1800-434MN is compatible with RFM's miniMESHTM network protocol, which provides add-on "plug- and-play" multicast mesh network routing. The DM1800-434MN is designed for operation under ETSI I-ETS 300 220 regulations.
