Serial RS485/RS422 to Ethernet LAN Terminal Server/Client


IP Electronix PH485Ex1 Serial RS485 RS422 to Ethernet bidirectional communication terminal server/client is a simple solution for connecting serial devices to a network which results in having 2 RS485 or RS422 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.

Protection against Surge, ESD and EMI is implemented in its design and it has 3kV isolation between Ethernet and RS485/RS422 sides.

PH485Ex1 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 ….
