PPT vs. VPRN - Position Tracking not Working

[mspusch]

If your PPT computer was configured to output on COM4, and you did not change the physical port the Nullmodem cable is plugged in,
then most likely you should set it to COM4 again.

In almost all cases when a PPT that has previously worked does not work any more, it's because

A) someone changed some basic setting on the PPT options (like outputting on the wrong port etc.)

B) the file that is selected for a calibration file is not a valid calibration file.
you need to click on the calibrate button and select the option 'load existing calibration file' and point the PPT at the most recent calibration file.

alternatively you can re-calibrate and create a new file. calibration should take you about 2min.

If you have re-calibrated and click tracking and the tracking button stays in, then you should see a solid white line when you move the marker around.

if that is the case, then connect your serial port 4 (COM4) over to the Vizard (rendering) computer with the Nullmodem cable,

then look up on the Rendering computer which COM port it connects to there on the rendering computer, and THEN specify with PORT_PPT = 5 (or whatever COM port on the rendering computer the NULLMODEM cable connects to) in the VIzard script.
