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 and two RS-485 ports. It is the ideal equipment for connecting RS-485 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, 2xRS-485 port
8 kV ESD protection
1.5 kV isolation protection for Ethernet port
3kV isolation protection for RS-485
One-key reset to default factory
Simple configuration via its built-in web interface
DIN-Rail 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 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 transparent 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.
