I have an obsolete KVH Tracphone antenna AU900A that has an integral
gyrocompass and inclinometer. The servos and gearing would make a great
land-based positioning device. I would also like to experiment with the
internal gyrocompass and inclinometer. KVH tech support will only tell me
that the interface for the units is "proprietary".

Does anyone have any experience with the KVH gyrocompass (020692 33 - 8
wire) and inclinometer (02 0693 21 - 6 wire) used in earlier tracphone
antennas? I have tried interfacing the serial RS422 port on the antenna PCU
controller board -- no joy. The antenna always parks North and responds to
changes in position, so I believe the gyrocompass and inclinometer are
functioning.

Anyone have any knowledge about these units that they would be willing to
share?
