3.7.3 Other Magnetic Compass
1) Connection
When receiving azimuth information data from the electronic compass, connect the necessary signal line
to the attached NMEA data connector P5 (for J5) LTWBD8BFFA-LL7001 using the following diagram
as the reference.
Magnet compass side Magnet compass side
(4) NSKRX - Data return
(3) NSKRX + Data output from the magnet compass side
Connector for GPS compass/NSK equipment (J5)
To GPS compass or NSK unit
(1) NSKTX- : Output of receiving signals from NSK+
(2) NSKTX+ : Output of receiving signals from NSK-
(3) NSKRX+ : Input of receiving signals from NSK+
(4) NSKRX- : Input of receiving signals from NSK-
(5) GND : Power GND for NSK
(6) ALM+ : Dry contact output 1
(7) ALM- : Dry contact output 2
(8) +5V : Power for NSK (+5V)
2) Setting Other Electromagnetic Compasses
Set the following information in the electromagnetic compass.
Data output format NMEA V2.0 OR LATER VERSION
Output sentence THS, HDT, HDG, HDM
Data transmission cycle Must be 50ms or less
20ms or less recommended
Baud Rate 38400bps/(4800bps)
The shorter the data transmission cycle the better. If the cycle is too long, image processing, trail
performance, and TT (target tracking) performance are affected.
3) Setting the JMA-5200MK2
