1. Introduction
IPEX PH422Ex2™ bidirectional communication terminal server/client is a simple solution for connecting serial
devices to a network which results in having 2 RS-422 (4-Wired RS-485) serial ports 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.
PH422Ex2™ 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.
PH422Ex2™ comes complete with drivers for Microsoft Windows XP/CE/2003/2008/7. Its setup file creates 2
virtual COM Port on your Server, PC or Laptop with configurable baud rate, 8 bits data length and 1 stop bit
fixed setting.

General Indicators:
POWER LED (Green): It is turned ON, when the power supply connects to +VDC and GND correctly.
SERVER LED (Green): It is turned ON if the device is in Server Mode.
CLIENT LED (Green): It is turned ON if the device is in Client Mode.
Port Indicators:
TCP LED (Green): It is turned ON if a TCP connection between the device and a remote Server/Client established.
PE LED (Red): It is blinking if the device detecting a Parity Error in data.
RX LED (Yellow): It is blinking when the device receive data on serial port.
TX LED (Green): It is blinking when data is transmitting from the device serial port.

7. Connection Diagram
7.1 PH422Ex2 as a Terminal Server
The below diagram is a typical connection configuration of PH422Ex2. You can connect two devices with a RS422 serial port to any RS-422 serial port of the PH422Ex2. Then you can connect to the device, behind the
network by any application software you want.
There are two methods in order to be connected to the PH422Ex2 COM Ports via Ethernet. As the first way, it is
possible to connect to the device by opening a normal COM Port (if you have installed PHEx2.exe software on
the PC or Laptop). The second way is connecting to PH422Ex2 by opening a TCP Socket without need of any
auxiliary driver.
To configure network settings of PH422Ex2 such as IP Address or Subnet mask, connect a computer with a
terminal emulator software (like Hyper Terminal) on it, to the COM1 of PH422Ex2 and restart PH422Ex2 by
pressing the Network Config. Button.
