Analogue Compass Repeaters 056376/A
Configuration Parameters 6-7
RCS Type
Sets the repeater device type.
Settings: automatic
Recognize heading data from gyrocompasses, THDs and
magnetic compasses. This is the factory default setting.
If data is received in the NMEA 0183/IEC 6116 protocol, the
repeater determines the active heading source according to
the following scheme:
Check the incoming data for $PPLAN or $PPNSD sentences
according to the “Status Selection” setting.
• If valid $PPLAN or $PPNSD sentences are found, check
the incoming data for heading from the selected source
(gyro or magnetic), according to the “GYRO Selection”
and “MAGN Selection” settings.
– If valid heading data is received from the selected
source, indicate heading and source.
– If no valid heading data is received from the selected
source, raise an error.
• If no valid $PPLAN or $PPNSD sentences are found,
check the incoming data for heading from any source
(gyro or magnetic), according to the “GYRO Selection”
and “MAGN Selection” settings.
– If valid heading data is received from one source
only, indicate the heading and source.
– If valid heading data is received from more than one
source, indicate the heading and source from the
highest prioritized source:
– Gyrocompass,
– THD,
– Magnetic Compass.
– If no valid heading data is received from any source,
raise an error.
Magnetic
Recognize magnetic heading data only. This is the required
setting for the magnetic heading repeater, type 5016-CC.
When installing a magnetic heading repeater, updating its
software or exchanging its PCB, make sure that this setting
is selected.
Gyro
Recognize heading data from gyrocompasses or THDs only.
This setting disables automatic fallback to magnetic head-
ing when gyro heading is lost.
