RS2ZBEE Serial Device Server & Modbus Gateway


Serial Device Server & Modbus Gateway


3Wire RS2ZBEE is an industrial grade Zigbee Serial Device Server for connecting your Serial and Ethernet devices, such as PLCs, meters, and sensors, over a Zigbee wireless Network.
Your communications software will be able to access the serial devices from anywhere on a LAN/WLAN thru the Zigbee network. Moreover, the ZIGBEE device servers require fewer cables and are ideal for applications that involve difficult wiring situations.
RS2ZBEE can operate as Modbus TCP Master, Modbus TCP Slave, Paired Mode, Bridge Mode with the data connection thru direct IP or Virtual COM.
