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.
