2.1 Understanding the Advantech EDG Series

The EDG series is an advanced data gateway unit. It extends
traditional COM ports of a PC with access over a TCP/IP net-
work. Through networking, you can control and monitor re-
mote serial devices either over a LAN or over the WAN.
Since the EDG series is connected through a TCP/IP network,
you will need to know some basic facts about networking in
order to get the server hooked up correctly.

2.1.1 Network Architecture

Traditional serial port communication uses a COM port board
that slides into one of the slots at the back of your PC. In this
case, only the computer containing the board can access the
serial port. With the EDG series, you are now able to access the
COM port from a distance through local area network. The EDG
series can be integrated within the network architecture of any
protocol. Note, all serial devices which are connected to the
port must have the same protocol running and the same trans-
mission speed. Connect devices running different protocols to
different ports of the EDG series.
