Chapter 1 Introduction
This chapter provides an overview of the PMC-1302 ESG and summarizes many of its key features.
1.1 Overview
The PMC-1302 ESG is an Industrial Ethernet Serial Gateway which provides one 10/100BaseT Ethernet
port, one RS-485 port and one RS-485/RS-422 port. It is the ideal equipment for connecting RS-485
or RS-422 enabled serial devices to an IP-based Ethernet LAN, making it possible to access serial
devices over your Ethernet network for any SCADA or Automation applications. The PMC-1302 ESG
has been specifically designed with industrial automation in mind and therefore provides
un-surpassed performance and reliability under the harshest industrial or commercial environments.
1.2 Features
1x10/100BaseT, 1xRS-485 port and 1xRS-485/RS-422 port
8 kV ESD protection
1.5 kV isolation protection for Ethernet port
3kV isolation protection for RS-485 and RS-422
Simple configuration via its built-in web interface
DIN-Rail or Wall Mount
Extended operating temperature
1.3 Applications
The PMC-1302 ESG supports the efficient transfer of serial packets between the upstream
network-based applications and the downstream RS-485 / RS-422 serial devices via a TCP/IP
connection. Instead of using a Windows based "Virtual COM" driver with a port-mapping utility,
which is often plagued with driver incompatibility among the many different Windows versions, the
PMC-1302 ESG allows applications to directly connect to it via a TCP/IP connection for the transfer of
serial packets inside TCP/IP frames to and from downstream serial devices. Perfectly suited for
communicating with industrial devices that have timing sensitive protocols, the PMC-1302 ESG
provides a reliable interface which allows SCADA or similar applications that already support direct
connection with Ethernet Gateway to communicate with serial devices independent of the serial
protocols used.

2.3 Mounting
The PMC-1302 ESG should be installed in a dry environment with no dust and kept away from heat,
radiation and electrical noise sources.
Installation steps:
Wall Mounting
Pre-drill four mounting holes on the back plate according to the diagram below.
Remove the two mounting plates (top and bottom) from the back of the PMC-1302 ESG by first
removing the screws that fix the mounting plates in place.
Re-position the mounting plates by sliding the top plate upward and the bottom plate downward
such that the area with the mounting holes protrude from the device's body and re-install the
screws that hold the mounting plates in place.
The PMC-1302 ESG package comes with four additional mounting screws in a little plastic bag.
Use these screws to mount the PMC-1302 ESG on to the back plate.
A Philips screw driver with a long shaft will ease the mounting process.
Figure 2-3-1 Wall Mounting
DIN-Rail Mounting
Before installation, make sure that the DIN rail is already in place
Align the top of the mounting clip at the back of the PMC-1302 ESG at an angle against the top of
the DIN rail as shown in the figure below
Rotate the bottom of the PMC-1302 ESG towards the back while applying a slight pressure to
make sure that the mounting clip is completely and securely fixed on to the DIN rail

2.4 RS-485 Wiring
The PMC-1302 ESG provides one RS-485 port (P2) and one RS-485 / RS-422 port (P3). Up to 32
devices can be connected on a RS-485 bus. The overall length of the RS-485 cable connecting all
devices should not exceed 1200m.
The following figure illustrates the RS-485 communications connections on the PMC-1302 ESG:

Chapter 4 Configuring the PMC-1302 ESG via Web Interface
4.1 Web Console Login
1) Open your Internet Explorer with the scripting function enabled. To enable scripting for your
browser, right click on your Internet Explorer icon and then select Properties from the pop-up
dialog box. The Internet Options window appears. Select the Security tab and then click on
the Custom Level button near the bottom of the window. The Security Settings window
appears. Enable the three options as shown below and then click OK.
2) The default IP Addresses of the PMC-1302 ESG’s two Ethernet Ports are 192.168.0.127.
Configure the IP Address and the Subnet Mask of the PC as 192.168.0.100 and 255.255.255.0 as
shown below.
3) Enter the IP Address of the PMC-1302 ESG in the Address input box of the Internet Explorer and
then press <Enter>. The default IP address is 192.168.0.127.

13

4) The PMC-1302 ESG’s Web Console Login page appears. Enter the User Name and Password.
The default user name is “user”, and the default password is “123456”.
5) Once the log-in credentials are confirmed, the following page appears.
4.2 Basic Settings
The Basic Settings page is divided into 3 areas: Network Settings, P2 Settings and P3 Settings.
1) Network Settings (P1)
The Network Settings for the Ethernet port can be modified here based on the actual situation. Click
Apply to save your changes. Please be reminded that the IP addresses for the Ethernet port and
Default Gateway should be in the same subnet.

14
Ceiec Electric Technology
2) P2 and P3 Settings
P2 is a standard RS485 port, and P3 is a RS485/RS422 port. All setup parameters such as Baud rate,
Data bits, Parity, Stop bits, IP Port and Timeout can be modified here. Please be reminded that the IP
Port number for P2 (default = 20000) and P3 (default = 20001) should be different. Click Apply to
save your changes. The following table shows the setup parameters for P2 and P3. Most setup
parameters are basic and self-explanatory. Please note that the Timeout parameter refers to the
timeout setting for the IP connection instead of the serial connection, meaning that the IP connection
will be closed if there are no activities between the application software and the PMC-1302 ESG for
the specified amount of time. This is to prevent a potential lock up of the IP connection at the
PMC-1302 ESG if the application software fails to close the IP connection for some unknown reasons.
It is recommended that the default Timeout of 300 seconds be used.

Chapter 5 Communications through the PMC-1302 ESG
This section provides details on how to communicate with a PMC-660V1.2 meter (Unit ID = 100) via
the PMC-1302 ESG.
5.1 Topological Graph
In this example, P2 on the PMC-1302 ESG is used. The default IP address for P1 is 192.168.0.127.
5.2 Configuring the PMC-1302 ESG
To configure the PMC-1302 ESG, the user can log on to its Web Console page via the Internet Explorer
by entering the IP address of the PMC-1302 ESG’s Ethernet port in the browser’s address bar. For
example, type http://192.168.0.127/ at the address bar and then press <Enter>.
Enter the default user name “user”, the default password “123456” and then click on the Login button
to open the PMC-1302 ESG’s Web Console.

17
Ceiec Electric Technology
In this example, P2 of the PMC-1302 ESG is used. The PMC-660’s serial port has been configured
with the following parameters:
1. Type = RS-485
2. Baud rate = 9600
3. Data Bits = 8
4. Parity = Even
5. Stop Bits = 1
It is important for the communications parameters of the PMC-1302 ESG’s P2 to be programmed to
match those of the PMC-660V1.2. The IP Port Number for P2 is 20000.
After the P2 settings of the PMC-1302 ESG has been correctly configured, click Restart menu item on
the left-hand pane to open the page and then click on the Restart button to complete the PMC-1302
ESG programming. The PMC-1302 ESG will perform a reboot operation with the new configuration.
When the Log-In page returns, the PMC-1302 ESG is now ready.
5.3 Configuring PecStar
In PecStar’s Systemconfig interface, select Site 1 on the left-hand pane and then click on the

18
Ceiec Electric Technology
Properties icon to bring up the Site Properties dialog box.
In this example, P1 of the PMC-1302 ESG is used, and Site 1 has been configured with the following
parameters:
1. Drive Type = MODBUS - RTU Protocol Master Site Driver,
2. Polling Mode = Serial
3. Port Type = Ethernet
4. IP = 192.168.0.127
5. Port = 20000 (for P2 of PMC-1302ESG)
Select PMC-660 on the right-hand pane under the Device Name column and then click on the
Properties icon on the Tool Bar to bring up the Device Node Properties dialog box. Change Type to
PMC660, Comm ID to 100 and then click OK to save and exit the dialog box.

19
Ceiec Electric Technology
Right click on Device 1 on the left-hand pane, click Import SNF file, and then select the appropriate
SNF file from the pop-up dialog box.
Click on the Save icon on the Tool Bar to save the current configuration into PecStar’s database. The
PecStar software is now ready to communicate with the PMC-660 via P2 of the PMC-1302 ESG.
