TCP Server Quick Start

Before you start

• Connect the physical RS232/RS485/USB serial device.
• Confirm the real COM port number in Windows.
• Choose a TCP listen port that is not already in use.
• Allow the TCP port through Windows Firewall if remote machines will connect.

Steps

1. Open ComLinker.
2. Go to TCP Serial Bindings and select the TCP Server tab.
3. Click Add.
4. Select the real serial port.
5. Enter the listen IP address and TCP port.
6. Set baud rate, data bits, parity, stop bits, and flow control to match the device.
7. Save and click Start.
8. Connect from the remote TCP client.

Expected status

Listening means the TCP server is waiting for a client. Connected means a remote TCP client is attached and data can pass between TCP and the serial port.
