#2 RS-485/422 Serial Port to Ethernet, Terminal Server/Client



IPEX PH485Ex2P bidirectional communication terminal server/client is a simple solution for connecting serial devices to a network which results in having 2 RS-485 or RS-422 serial ports over Ethernet network. This converter uses transparent communicate protocol, so it is not required to understand complex Ethernet TCP/IP protocol, and no modification in serial programs is needed. It operates as a Real COM, TCP Server, TCP Client, UDP Server and UDP Client Full-Duplex converter and supports bidirectional connection.

PH485Ex2P is designed for industrial usage and is useful for connecting any device with a serial interface to a computer via Ethernet supported network like LAN, WAN … and can be used in Industrial Automation, Telecommunications, SCADA Systems, DCS Systems ….

Protection against Surge, ESD and EMI is implemented in its design and it has 3kV isolation between Ethernet and RS-485 sides.
