fastrak

[Steve_HT]

Hello,

I'm trying to use the Polhemus fastrak unit. I have the unit connected on COM1 and a cyberglove on COM2. 'Cyberglove.dls' seems to work fine, but 'fastrak.dls' is unable to connect to the device, even though it's clearly available and running in the Immersion software.

What am I missing here?

I've also tried "Patriot_HeadHand" with both the patriot plug-in and the fastrak plug-in with no luck.

Did you specify the port before adding the fastrak.dls sensor? Your code should look something like this:

PORT_FASTRAK = 1
fastrak = viz.add('fastrak.dls')

That doesn't seem to help

[farshizzo]

Are you getting an error message? If so, can you please post it.

The code:

viz.go()

glove = viz.add('cyberglove.dls')

PORT_FASTRAK=1
polhemus = viz.add('fastrak.dls')

The Error:

Is the unit set to communicate over serial at a baud rate of 115200? You can check by making sure switches 1, 2, 3, 5, and 8 are UP.

[Steve_HT]

Yep, they are set. As I said, it communicates just fine with the Immersion Technologies software. Is there perhaps a Polhemus driver that I'm missing, or something like that?

[farshizzo]

If you are connecting the Fastrak over USB, then you do need to install a driver. But, as far as I remember, you don't need any additional drivers when connecting over serial.

You mentioned that the Fastrak communicates fine with the Immersion software. Did you mean that it communicates fine with the Polhemus software? The CyberGlove is an Immersion product, not the Fastrak.

[Steve_HT]

Yeah, I uploaded new Polhemus firmware onto the Fastrak, but otherwise have not been using any Polhemus at all. My communications are through the standard serial port.
