1. INTRODUCTION
IPEX PH232Ex2 bidirectional communication terminal server/client is a simple solution for
connecting serial devices to a network which results in having 2 RS-232 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.
PH232Ex2 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 insulation
between Ethernet and RS-232 sides. Furthermore, all the RS-232 ports are insulated from each
other too.

8. GENERAL INDICATORS
POWER LED (Green): It is turned ON, when the power supply connects to +VDC and GND correctly.
9. PORT INDICATORS
TCP Server LED (Green): Blinking this LED shows that the TCP Server mode for this port is selected and
device is trying to connect in this mode. If the device connects to a client, then this LED turns on
continuously.
TCP Client LED (Green): Blinking this LED shows that the TCP Client mode for this port is selected and
device is trying to connect in this mode. If the device connects to a server, then this LED turns on
continuously.
UDP LED (Green): Blinking this LED shows that the UDP mode for this port is selected and device is
trying to connect in this mode. If the network works properly, then this LED turns on continuously.
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.
REDIRECT IN (YELLOW): It is turned on if data from other ports are redirected to this port.
REDIRECT OUT (GREEN): It is turned on if data from the port are redirected to any other port.
10.DEVICE POWER SUPPLY
To working properly, you should connect a DC Power Supply to PH232Ex2. The voltage of the Power
Supply should be from +8V to +48V. For example, this device is working with a single +12V, +15V or
+24V DC Adaptor as well.

13.CONNECTION DIAGRAM
-PH232Ex2 as a Terminal Server
The below diagram is a typical connection configuration of PH232Ex2. You can connect a device with a RS-232
serial port to RS-232 serial port of the PH232Ex2, then you can connect to the device behind the network by any
application software you want by opening a TCP or UDP Socket without need of any auxiliary driver.

-Client/Server, Peer to Peer Connection
If you want to connect two devices which have only RS-232 Ports to each other via Ethernet network, you can
use this connecting method. Take two PH232Ex2. Set one PH232Ex2 as Server and another one as Client with
adding Remote Server IP and Port Number on it. These two converters are connecting automatically via network
to each other, so RS-232 PORT of Server, connects to RS-232 PORT of Client via network. Now you can connect
your RS-232 devices to COM Ports as shown in the following diagram.

Default IP Address: 192.168.1.100
Default Subnet Mask: 255.255.255.0
Default User Name: admin
Default Password: admin
IMPORTANT NOTICE:
If you change the device IP and forget it, you can see the new IP Address on the serial port. Whenever you turn
on the device, it sends its IP Address and Subnet Mask to the RS-232 PORT1. The ports settings for watching
device IP are fixed to 9600, 8, n, 1. You can easily see this IP Address and Subnet Mask by using a Terminal
Emulation Software such as Microsoft Hyper Terminal.
You can also Reset the device to its Factory Default Settings in this page if necessary.
