EtherPath-X4 User’s Guide
Chapter 6
Operation
This Chapter explains how to use the EtherPath, once it is installed and configured.
Although it may be used with automated equipment such as RTUs, POS, or other
computer-based devices; the example configurations shown in this chapter use terminals
or terminal emulation on a PC for illustrations. It is often useful to set up the EtherPath
using this method before connecting other equipment.
Overview
The EtherPath-X4 operation is similar to the single port EtherPath products. Each serial port on the
EtherPath-X4 is independent of the others with regard to protocol, speed, parity, flow control, and IP port
number. All four ports share the same IP address.
Client/Server Point-to-Point (Nailed-Up) Mode
•
Both EtherPaths must be correctly installed and configured as described in Chapters 3 or 4. One serial
port device is connected to the “Server” EtherPath, and another serial device is connected to the
“Client” EtherPath. One EtherPath has the operational mode set as a "Server", the other has the
operational mode set as a "Client".
•
The communication settings for the serial devices must be the same as the values entered into the
EtherPath device they each attach to.
•
Power up the "server" EtherPath.
•
Power up the "client" EtherPath. It will automatically connect to the remote EtherPath whose IP
address was stored during configuration if hardware dialing is enabled and DCD Input is asserted.
•
You may now proceed as if the remote serial port device was directly connected to the serial port of
your local serial device.
•
If
DCD Input control
is set to
From Interface
, then the serial device must provide a high level signal on
DCD Input before the EtherPath will accept or place an Ethernet connection.
