Hi,

I am trying to connect Vizard to Polhemus Liberty Latus.

First of all, I set up the receptor and marker according to the user manual of Polhemus Liberty Latus. Then I launch a wireless marker successfully using the PiMgr program supplied by the Liberty Latus. The marker can track accurately when run with PiMgr.

Then with everything open, I input the following codes in Vizard according to the user reference in Polhemus Plug-in:

polhemus = viz.add('polhemus.dle')
libertylatus = polhemus.addLibertyLatus(marker=0,receptor=1)

It has no problem in creating the Polhemus extension. But trying to connect with Liberty Latus gives me the following error:

** ERROR: Failed to connect to a Patriot Wireless/Libert LATUS: Device not found
** ERROR: Failed to create extension sensor with polhemus.dle

Then I also tried to specify the number for marker and receptor. But same error messages come up.

Thanks in advance. Any help is appreciated.

When you say "with everything open", are you referring to PiMgr? I don't think to applications can access the device simultaneously, so you should close down PiMgr before attempting to connect to the device in Vizard.

Hi farshizzo,

Thanks for your reply. I tried again with PiMgr closed (Liberty Latus & marker open). I got a dialog box jumped out, saying: An unhandled win32 exception occured in winviz.exe[3712].
Any idea why?

Thanks in advance!
