PortServer TS P MEI makes it easy to connect RS-232/422/485 serial devices to an IP network. By supporting versatile powering options like power over Ethernet and serial port power, this serial server can adapt to many applications where traditional power options are not available.

Power over Ethernet (802.3af, mid- and end-span support) makes it possible to run just one Ethernet cable to the device server for both power and communications. The serial port power feature enables PortServer TS P MEI to power a device over serial using Ring Indicator (RI) or DTR pins. Power over Ethernet can be used in conjunction with a conventional power supply to provide redundant power capability to the device.

Available in two- and four-port versions, PortServer TS P MEI delivers universal, high performance multiport serial-to- Ethernet connectivity. It is ideal for applications requiring COM ports, serial tunneling, or where TCP/UDP Socket functionality is needed.
