Long Range Sub-GHz Modbus RS485 Bridge with Pulse Input and Discrete Output
The main role of the DM-108 is to act as wireless bridge inside traditional wired RS485 Modbus RTU installations, providing the limited point-to-point RS485 networks with the versatility and ease of installation of wireless networks. Setting up mesh nets with multihops support, each device could transmit up to +27dBm to reach up to 5 kilometers around.
Once properly configured, the DM-108 becomes transparent inside the RS485 network, not only maintaining the electric requirements of the bus, but also the integrity of Modbus RTU packet frames transmitted.
