VxComm 014

Q1:

Is it possible to change the communication port on the protocol TCP/IP use for the internal network?

Q2:

with I-7188En series the COM1, COM2, COM3,... of the modules are related to IP-Port-Numbers 10001, 10002, 10003,... .
Now some customers would like to use another IP-Port-number on the COM-ports especially when firewall rules block the port numbers.

What do you think about the idea to implement "configurable IP-port number" in I-7188En ?

Change the command Port: "/P"

Edit the autoexec.bat to add a argument as follow, and download it to 7188E using the MiniOS7 utility. (http://www.icpdas.com/download/minios7.htm)

vcom3009 /st300 /p200

/Pxxxxx

Change the command port (default is 10000). If Command Port 10000 is changed to 200, and then TCP/IP mapping port of COM port will be 201~208.

If you develop your Xserver-based program, you can change the

'Port10000' variable to any one port number (0~65535) what you want.

Please download the latest version of the firmware

from ftp://ftp.icpdas.com/pub/cd/8000cd/napdos/7188e/tcp/vxcomm/server(7188e)/

or the library related to Xserver located on

the http://www.icpdas.com/download/7188sdk.htm.

Note: The version of I7188E firmware must be v3.0.09 dated on 2003/11/07 or later.

For example

vcom3009 /st300 /P200 /m1

Connet to I-7188E with IP 10.0.8.228 and Port 200.

The default TCP/IP mapping port of COM port will be changed from 10000 to 200, 10001 to 201, and 10008 to 208.
