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.
