Compass - External Compass Input & Magnetic Variation Table - Leica MX400 Operating Instructions Manual

Configuration
Compass - External Compass Input & Magnetic Variation Table
The receiver will accept a magnetic compass input using the NMEA
0183 data record of xxHDT, xxHDG, xxHDM, xxHCC, xxHCD,
xxVHW, or any of the above. "xx" refers to the Talker Identifier as
specified in the NMEA 0183 standard. The receiver will accept
these data records from any talker ID, and from any version (1.5 to
2.1) of the NMEA 0183 standard.
To implement this feature, change Transducer Connected to Yes.
Identify the appropriate input port that the compass connects to the
receiver using the Change softkey or cursor.
Select whether or not the receiver should give an alarm if data is not
received on the input port.
Select the compass type, either Magnetic or Gyro. Only the NMEA
0183 records identified above are accepted for the gyro input. To
connect a stepper/synchro output to the receiver, these signals must
be converted to a standard NMEA 0183 record of HDT, HDG,
HDM, HCC, HCD, or VHW.
Magnetic:
Select the magnetic deviation method: either In Compass - the
deviation is corrected before being sent to the receiver; or In
Navigator - the deviation is corrected by editing a deviation
table (Edit Table softkey) in the receiver.
