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



IP Electronix PH422Ex1™ bidirectional communication terminal server/client is a simple solution for connecting serial devices to a network which results in having 1 RS-422 (4-Wired RS-485) serial port over Ethernet network which is compatible with RS-422 standard devices differential Tx+,Tx- & Rx+,Rx- signals. 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 or TCP Client Full-Duplex converter and supports bidirectional connection.
PH422Ex1™ 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, and DCS Systems ….
Protection against Surge, ESD and EMI is implemented in its design and it has 3kV isolation between Ethernet and RS-422 sides.
PH422Ex1™ comes complete with drivers for Microsoft Windows XP/CE/2003/2008/7. Its setup file creates a virtual COM Port on your Server, PC or Laptop with configurable baud rate, 8 bits data length and 1 stop bit fixed setting.
