1. Introduction

IPEX PH485Ex1™ bidirectional communication terminal server/client is a simple solution for connecting serial
devices to a network which results in having 1 RS-485 serial port over Ethernet network and is compatible with
RS-485 standard devices differential Data+ & Data- 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.

PH485Ex1™ 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-485 sides.

PH485Ex1™ 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.

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.

Device Power Supply +VDC (IMPORTANT!)

To working properly, you should connect a DC Power Supply to PH485Ex1. The voltage of the Power Supply
should be from +10V to +30V. For example, this device is working with a single +12V, +15V or +24V DC Adaptor.

7. Connection Diagram

7.1 PH485Ex1 as a Terminal Server

The below diagram is a typical connection configuration of PH485Ex1. You can connect one device with a RS-485
serial port to COM1 RS-485 serial port of the PH485Ex1. 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 PH485Ex1 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 PH485Ex1 by opening a TCP Socket without need of any
auxiliary driver.

To configure network settings of PH485Ex1 such as IP Address or Subnet mask, connect a computer with a
terminal emulator software (like Hyper Terminal) on it, to the COM1 of PH485Ex1 and restart PH485Ex1 by
pressing the Network Config. Button.
