AXB-PT10/30 PosiTrack Camera Controllers
This table lists the return/response strings from the PosiTrack units.
Response mask
Data is automatically sent if the PosiTrack units receive a change request. The response mask
should be disabled if the change request data is not used. Bits in the response mask
(the Return/Respond Strings from the PosiTrack Units table) turn data off.
