1. INTRODUCTION
IPEX PH485Ex4bidirectional communication terminal server/client is a simple solution for
connecting serial devices to a network which results in having 2 RS-485 or RS-422 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 RS-485/RS-422 sides. Furthermore, all the RS-485/RS-422 ports are insulated from each
other too.
PH485Ex4is 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 ….

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 PH485Ex4. 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.
