3WIRE - RS2ZBEE IoT Gateway 3WIRE Serial Device Server 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.


  • Links Serial and Ethernet devices to an Zigbee network; simultaneous access over Ethernet & Serial
  • Optical isolation of 1500V on RS485 / RS422 data lines; 2kV surge protection on Ethernet Port
  • Supports baud rate of 1200bps ~ 115200bps, 5 ~ 9 bits and parity can be “None”, “Odd”, “Even”, “Mark” & “Space”
  • Serial port interface for RS232 / 485 / 422; terminal block for RS485 & RS422 and DB9 for RS232
  • Supports 10/100 Mbps Ethernet
  • Operates in Multi-Serial, STAR, MESH, & TREE Mode
  • Power / Link / Active LED indicator
  • Secure data access with 16encrypted channels
  • Upto 256 slaves connected on RS485 / 422 bus
  • Each Zigbee Master can connect upto 32 Zigbee Slave
  • Multi-mode operation; TCP Server, TCP Client, UDP Mode, UDP Multicast
  • Modbus TCP Gateway function (converts Modbus RTU to Modbus TCP)
  • Supports 30 TCP clients at TCP Server and 7 destination IP as TCP Client
  • Heartbeat & Keep Alive function ensures a reliable connection
  • Virtual Port operation using 3Wire ComPort Emulator software
  • Automatic discovery and configuration using provided 3Wire Device Management software or Web Browser configuration
  • Wide voltage 9VDC ~24VDC with dual voltage input; Screw Terminal or DC-Jack
  • Plug-in screw terminal wiring; accepts AWG12 ~AWG30 wires.
