Use the Increase (
) and Decrease ( ) keys to adjust the display value until it matches the
known heading to which the boat is pointed. Press the Accept ( ) key to accept the value when you
are satisfied. If you do not wish to perform installation offset calibration at this time, press the Abort (
) key and the installation offset will not be altered.
6.23.4 Inverted Installation Entry
Normally, the SSC200 is mounted so that the label on the compass is facing up and the NMEA 2000
®
and NMEA 0183 connectors are facing towards the bow of the vessel. A recent version of SSC200
firmware supports mounting the compass upside-down (for instance, to a ceiling), or backwards (with
connectors facing towards the stern of the vessel, so that the SSC200 can be mounted to the aft side
of a bulkhead). If either of these mounting options is used, the DSM150 can be used to inform the
SSC200 of this fact so that it can adjust heading, rate or turn, pitch, and roll readings to be corrected
accordingly.
