Failed to connect to intersense

[Karma]

Hello,

I am trying to set up a 2 camera PPT-X system and for some reason the cameras are not picking up the calibration rig.

I tried running this code

import viz
viz.go()

PORT_INTERSENSE = 3
isense = viz.add('intersense.dls')

but I get this output

******************************************************************************
** Loading Test.py
******************************************************************************
intersense.dls           	Intersense Driver v4.0.4
** ERROR: Failed to connect to intersense on port 3.
** Load Time: 3.11 seconds

(the next part pops up when I close the test window)

InterSense Library ver. 4.04 32-bit

Looking for InterSense tracking device number 1. 
Please wait ...
InterSense tracker not present

I saw a previous thread that said to check the port, but I think port 3 is the correct one to listen from.


At one point one of the camera was detecting the calibration rig but now it just looks like this.


Thanks for the help!
