Handling Port Conflicts with STU SigCaptX
By default STU SigCaptX uses a service port number of 9000.
This can occasionally cause problems on systems where other applications are also using the same port number or where firewall or anti-virus software is restricting access to it.
If STU SigCaptX cannot gain access to port 9000 then it will not run.
If the access is being prevented by security software (this has been experienced particularly with Kaspersky) then one solution is to change the settings in the security software so that it allows access to that port.
An alternative solution is to change the port number which STU SigCaptX uses - this requires coding and a registry setting change as described below.
1. Registry setting
For more details please see the SigCaptX installation guide
Location: HKEY_LOCAL_MACHINE\SOFTWARE\Wacom\SigCaptXSTU or HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Wacom\SigCaptXSTU
Change the Port number from 9000 to another number which you believe is less likely to cause a conflict.
Location: Please search in your code for anywhere where a reference is made to the service port, e.g. in wgssStuSdk.js as follows:
var defPort = 9000;
Having found this line of code change the value "9000" to be the same as the new value which you have set up in the registry for "Port".
So if you have specified a Port value of 14500 then the code would now read:
var defPort = 14500;
You may also need to change references elsewhere as for example in our sample Web page PortCheck.html where "9000" will need to be changed to "14500":
Service port: <input type="text" id="portText" value="9000">
