Polhemus woes

[tobin]

The device can be reliable but you have to do a few things:

1. In PiMGR, set the hemisphere tracking on.
2. After power cycling the unit, the hemisphere gets locked the first time Vizard connects to the Polhemus device. When connecting for the first time since powe cycling, hold your sensor/s all in the +X Polhemus hemisphere (side opposite the cord).
3. From that point on (at least until you power cycle again), you should have no more switching.
