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:

2.7 Power Supply Wiring
For AC supply, connect the live wire to the L/+ terminal and the neutral wire to the N/- terminal. For
DC supply, connect the positive wire to the L/+ terminal and the negative wire to the
N/- terminal. Connect the GND terminal to ground.
