1. Introduction
IPEX 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.

7. Connection Diagram
7.1 PH422Ex1 as a Terminal Server
The below diagram is a typical connection configuration of PH422Ex1. You can connect one device with a RS-422
serial port to COM1 RS-422 serial port of the PH422Ex1. 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 PH422Ex1 COM Port 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 PH422Ex1 by opening a TCP Socket without need of any
auxiliary driver.
To configure network settings of PH422Ex1 such as IP Address or Subnet mask, connect a computer with a
terminal emulator software (like Hyper Terminal) on it, to the COM1 of PH422Ex1 and restart PH422Ex1 by
pressing the Network Config. Button.

7.2 Client/Server, Peer to Peer Connection
If you want to connect two devices which have only RS-422 Ports to each other via Ethernet network, you can
use this connecting method. Take two PH422Ex1. Set one PH422Ex1 as Server and another one as Client with
adding Remote Server IP on it. These two converters are connecting automatically via network to each other, so
COM1 of Server connects to COM1 of Client via network. Now you can connect your RS-422 devices to COM
Ports as shown in the following diagram.

8. Device Network and Serial Port Settings
As shown in the connection diagram, you can connect a PC or laptop with a RS-422 serial COM port directly to
the Port 1 of PH422Ex1.
Now run a terminal emulator on your computer. You can find some terminal emulators in the Utility folder in
the installation CD. For example, we use Microsoft Hyper Terminal. Run Hyperterm.exe and then from the
properties toolbar, set the serial settings to the 19200, 8, n, 1 like this:
Remember to set Flow Control to None. Now in the Properties dialog box, select settings tab and click on the
ASCII Setup. Select the “Echo typed characters locally” and press OK.

Turn on the PH422Ex1 by connecting +6V DC adaptor. If all the connections are OK, you should see the default
settings on the Hyper Terminal.
Entering Device Network and Serial Ports Setting Menu (IMPORTANT!)
Now to enter device network and serial ports settings menu, follow the below procedure step by step:
1- Push the CONFIG button on the right side of the front panel (Do not release it).
2- Press (and release) RESET button on the left side of the front panel.
3- Release the CONFIG button.
You should be able to see the network settings menu like this picture:

: User’s Manual
You can see network default settings in this page. It is possible to change the entire network and serial ports
settings from this menu, For example, if you want to change the IP Address of the device, first press “1”, enter
new IP Address and then press “Enter”. At last press “S” to save changes and quit. The device will be restarted
automatically and booted with new settings.

9. Network Connection Testing
Connect PH422Ex1 to the Ethernet based network by connecting RJ45 LAN socket to network via a switch or
Hub by an ordinary CAT5 or CAT6 cable. If everything is set properly, the green and yellow LEDs on the
PH422Ex1’s RJ45 socket will blink.
Now it is important to check the network wiring topology, and testing all the cables, routers, switches … in the
route from PH422Ex1 to the computer. This test is done simply by using PING command from computer.
Go to Windows command prompt, (press WINDOWS KEY + R to going to run dialog and then type CMD and
press enter):
Type ping with the device IP address, for example “ping 192.168.0.2”and press Enter.
Now you should see the ping response from the device.

If there are any problems in the network, you could not see response from the device:
If you see this timeout window, you can’t continue installation and first you should solve network problem by
consulting your network administrator.

10. Connecting to Device via TCP Socket
It is possible to directly connect to PH422Ex1 RS-422 Serial Port from any node of the network by using socket
programming. This is simply done if you know only PH422Ex1 IP Address and socket port number for each Port.
The port numbers is as follow:
- Port 1 : 9761
- Port 2 : 9762 (Only in PH422Ex2 Model)
For example we connect to Port 1 by means of Hyper Terminal. Run Hyperterm.exe and from properties dialog
box, select “TCP/IP (Winsock)”:
Enter device IP Address in the “Host address:” section, for example 192.168.0.2 and the port number in the
“Port Number:” section (port number for Port 1 is 9761 and for Port 2 is 9762), then click on OK.
Now if you type some characters, you can see that port 1 TX Blue LED is blinking that means the data is sent to
PH422Ex1 port 1.
NOTICE: Don’t forget to set PH422Ex1 in SERVER Mode for this method of connection.

11. Installing the Driver Software
The second method for connecting to PH422Ex1 serial ports is to install virtual COM port driver on your
computer and open ports as a normal Windows COM port.
Run PHEx2_32bit.exe if your Windows is 32 bit or PHEx2_64bit.exe if it is 64 bit from the installation CD.
NOTICE: In the Windows 64 bit systems, run apply.bat and restart your computer before setup.

12. Set Windows COM Ports for PORT 1 & PORT2
After installation is finished, stop any running application on your system and then from Windows
Start/Programs/IPEX/ run PHEX2.exe:
Simply Enter PH422Ex1 IP Address and serial port number for Port 1 and Port 2 and then press apply. For
example type 4 for Port 1 and 5 for Port 2, after applying is finished, restart your computer and then you can use
Port 1 as COM4 and Port 2 as COM5 like an ordinary Windows COM port by your application software.
