STU
Convert existing application to work with the 430V or 540 in serial mode
In order to capture signatures from the STU-430V or the STU 540 operating in serial mode your application must know which serial port the STU is connected to.
Please read the FAQ on STU Serial Connection to work out the relevant virtual COM port number.
You then have two options:
-
Specify the COM port and baud rate in the registry
-
Specify the COM port and baud rate in your application. Below is an example using C#:
DynamicCapture dc = new DynamicCaptureClass();
dc.SetProperty("stuPort", "COM3");
dc.SetProperty("stuBaudRate", "128000");
DynamicCaptureResult res = dc.Capture(sigCtl, "Who", "Why", null, null);
If you need technical assistance with the above please raise a support ticket by clicking on "Submit a request" at the top of this web page.
NOTE:
In most cases it is not practical to use the 540 in serial mode unless using its on-board images because the upload of external images to the 540 is too slow. Using monochrome images would improve matters but the best solution with a serially configured 540 is to use its on-board images as explained in the following FAQs:
