The Industrial Serial Server SE8502-M12 is 2 Port IP68 gateway for Ethernet (TCP/IP) and serial signal communications. The rugged aluminium case together with the M12 connectors provides waterproof, dust proof and vibration resistance protection. Other features include a high operating temperature from -40 to 75 ºC and 15KV ESD protection for the serial signals

It allows almost any serial device to be connected to a new or existing Ethernet network. By encapsulating serial data and transporting it over Ethernet, SE8502 offers full-duplex and bi-directional data that is transmission transparent between the serial port and the Ethernet network.

SE8502-M12 supports multiple link mode with TCP server/client, UDP and VirtualCOM that can be configured by a free Windows based utility. Configuration can be by built in Web Server or Serial Console or Telnet.

Because of its rugged design it is widely used in moving vehicles such as trains and construction equipment.
