DM2100

The DM2100 is a 916.5 MHz transceiver module designed for wireless industrial sensor applica

tions. The DM2100 is equipped with seven I/O ports. Each port can be configured as an analog

input, a digital input, or a digital output. The DM2100 is also equipped with a serial data port. The

communication range of the DM2100 in an “open field” environment is typically 200 meters/hop.

The DM2100 combines RFM’s low-current ASH radio technology with low-power microprocessor

technology to achieve very long battery life. The DM2100 employs NOKOTA’s SOS-OEA V1.5

multi-mode mesh network protocol, which provides robust and flexible wireless network routing, a

rich application command set, and a powerful and easy-to-use network management utility. The

DM2100 is certified under FCC 15.249 regulations.
