ComNet (Communication Networks) introduced a serial data to Ethernet terminal server. The purpose of this unit is to take RS232, RS422 and RS485 serial data, convert it to IP, transport it over an Ethernet network and convert it back at its destination. The CNFE3DOE2/M provides control of the remote hardware, as if it were connected directly to a PC COM port. It allows any combination of two serial data circuits to be inserted onto any Ethernet network. CNFE3DOE2 units include two serial data input/output ports, and three Ethernet ports that feature two TX ports and one SFP port.
