Device Server, Hubs and Repeaters
Serial Device Servers
The serial device servers provide RS-232 and RS-422/485 devices with Ethernet connectivity. This removes the cable length limitation of the physical serial port and extends the maximum distance of the host PC to the entire network by means of a "virtual" COM port.Device Server with PoE
Serial Repeater
Isolators and repeaters for the serial interface (RS-232/422/485) help with electrical or signalling interference acting on the cables by dividing the signal path into isolated sub-segments or processing noisy and distorted signals without changing the information content.
