TCP2RTU is a transparent both directions converter of the MODBUS TCP protocol, running over Ethernet, into the MODBUS RTU/ASCII protocol, running over RS485. TCP2RTU works both directions since version 1.4. Either as a Modbus gateway (Master) or as a Modbus Slave.

Configuration can be made over the internal WEB interface.

• MODBUS RTU/ASCII over RS485
• Two communication sockets on one Modbus Port.
• One port for RAW data communication (Ethernet to RSxxx converter).
• Configuration: Internal web pages or via Telnet.
• Power supply range: 8 - 30 V DC
