7.2.6 ACU Gyro Compass Type
There are multiple types of Gyro compasses, each of which requires a unique selection.
The SAMYUNG ENC antenna supports the following Gyro type.
NOTE: SYNC and STEP gyros require a direction setting which provides two choices:
Normal and Reverse.
NOTE: The SYNC gyro also requires a frequency setting which provides two choices:
50/60Hz and 400/500Hz.
When the Direction setting = NORMAL, a change in voltage is proportional to a change
of heading within a defined ratio (e.g. 1:1, 360:1, etc.). When the Direction setting =
REVERSE, a change of voltage is inversely proportional to a change of heading in a
defined ratio (e.g. 1:1, 360:1, etc.).
