Description and Behavior
Ports used by the EtherPath
The EtherPath uses 3 ports, as follows:
Port
Description
Data Port
‘Server Mode’ EtherPath listens at the port and
offers a raw TCP connection. This port number
is configurable. Default is 3000.
From
Port
The ‘Client Mode’ EtherPath uses a sending
port between 1025 and 4999 to connect to its
Remote Host. The port number starts at 1025,
and increments as needed. Note that EtherPath
version 5.2 and earlier always used port 5000 as
the sending port.
8000
Provides a telnet configuration service for all
modes. Do not use port 8000 in user-written
programs.
For user-written client application, avoid port number 8000. The
"Server" will respond to any configured port number other than that.
Server Mode
In Server mode, the EtherPath runs under the TCP/IP network
protocol. It will listen on a configured port number. The server will
wait for connection after initialization.
After a connection is established, the server always keeps checking
for data on both Ethernet and Serial Ports.
