Vizard and PPT - press TALK to communicate

[mspusch]

To get the WorldViz Precision Position Tracker PPT to send data over the serial port to your Vizard rendering computer, you'll need to activate the TALK button. If you don't do this, Vizard will not be able to receive any position data from the PPT device.

I have PPT and Vizard on different PCs. How to set PPT to talk to the other PC?
Thx
