3.4 COM Port Configuration

Figure 3.28 COM Port Configuration by Web page

3.4.1 TCP Server for Link Mode

TCP Server mode is the default Link mode of serial settings, and it can wait for connecting requirement from

remote host PC which “serial-to IP” tool installed or counter-pair SE5404D Serial servers in tunneling mode. One

shall configure listening port to allow establishing connection; Default port numbers of Serial Server are 4660 –

4667/4675.

If you wish to setup two SE5404Ds in tunneling mode, one SE5404D should run as a TCP Server and the other

should run as a TCP Client. Server’s Local Port should match Client’s Destination Port. Client’s Destination IP

should match Server’s IP. Detailed steps are described below.

1. Prepare two SE5404Ds (A and B). Note that you can treat each COM port as an independent device.

2. SE5404D A= 10.10.50.100. SE5404D B = 10.10.50.101 (You can use different IPs, but both SE5404Ds need

to be in the same subnet).

3. When connecting SE5404D to the instrument or to the PC over RS-232, please use a cross-over cable.

4. Enable “Virtual COM” on the WebUI for both SE5404Ds (First option in COM settings).

5. Set SE5404D A COM1 to TCP Server mode. Set SE5404D B COM1 to TCP Client mode IP and port equal to

SE5404D A COM1’s settings (Default Destination IP=10.10.50.100, Default Destination Port = 4660).

6. (optional) Repeat for remaining COMs: Set SE5404D A COM2 to TCP Server mode. Set SE5404D B COM2
