1. Introduction
The ED-10 TCP is an Industrial Ethernet Adapter acting as a serial server. The type of
serial interface is selectable between RS-232 and RS-422/485. The Ethernet interface is
10BASE-T and TCP/IP Protocols are implemented for network communication.
The ED-10 TCP provides a remote serial interface for a computer connected through a
TCP/IP network.
To complete the connection to the ED-10 TCP additional software need to be used in
the computer. Different solutions are possible, e.g.:
1. Telnet to the ED-10 TCP.
All keystrokes are trans-
ferred to the remote seri-
al interface.
Any characters received at
the remote serial interface
are transferred to the
computer screen.
2. A COM port redirector
software can be used to
create up to 256 virtual
COM ports.
This software will redirect
data, originally sent to a
local COM port, to the remote serial inter-
face of the ED-10 TCP. No change of com-
puter application software is then necessary.
3. Customer written software can be used to
directly access the network interface (socket
compliant) of the ED-10 TCP.
A sample written in C++ can be found on
the CD ”\Software\Sample\sample.zip”
