fastrak

We have never gotten the software delivered by Polhemus to work. All of our communications with the Fastrak have been through either Hyperterminal or Immersion Technologies' Device Control Unit.

I believe our fastrak plugin uses the same library to access the data as the FASTRAK GUI. Have you contacted Polhemus about this problem? I'm afraid there is not much more I can do. One option might be to use the VRPN plugin to access the Fastrak. I've never tried it myself, but VRPN claims it supports the Fastrak.

Okay, thanks

Okay, I have the Fastrak GUI up and running and talking to the box, and still getting the same response when I try to load the fastrak.dls:

cyberglove.dls CyberGlove Driver v1.0
fastrak.dls Polhemus Fastrak v1.0
** ERROR: Failed to connect to Polhemus Fastrak
Loading File: hand.cfg
** Load Time: 2.03 seconds

That's good you got it working with the GUI. What was the solution to that? I've made some small modifications to our fastrak sensor so it prints out a more useful error message. Email me at lashkari@worldviz.com and I will send you this new version. Hopefully this will help us track down the root of the problem.

[Steve_HT]

i'm not sure. Perhaps a new computer. I installed the software and it started running right away.

I've sent you an email.

What advice would you give to someone who is trying to use the the fastrak dls over a USB connection? FTgui works just fine, but with the following code:

polhemus = viz.add('fastrak.dls')
polhemus.reset()
viz.tracker()

one of two things happen. Either the boring error message:
fastrak.dls Polhemus Fastrak v1.0
** ERROR: Failed to connect to Polhemus Fastrak over USB or COM1

Or the program simply exits instantly after opening a new window and giving the following output:
fastrak.dls Polhemus Fastrak v1.0
** NOTIFY: Connected to Fastrak over USB Connection
2 station(s) detected

Which to me seems like its working? This also happens on the testPolhemus script. I get the same results whether or not I include the "PORT_FASTRAK = 1" option or any variation thereof. How should I go about making this work?
