9.3.6 Connecting an electromagnetic compass Attention • Ensure that the output of the inboard power supply and rectifier unit and connection to the power cable is correct. Erroneous connection or voltage may cause breakdown. It is possible to input information on bearing to the radar display unit if you use the electromagnetic compass with a NMEA0183 output terminal. (It is impossible to connect if you use the electromagnetic compass without a NMEA0183 output terminal.) (1) Solder the data cable of electromagnetic compass (with NMEA0183 output) to the 8 pin connector. The polarity is as shown below and care should be taken in making this connection. 8 pin connector (pin 3) Electromagnetic compass data (+) 8 pin connector (pin 4) Electromagnetic compass data (-) Type of LTWD-08BFFA-L180 (JRC code: 5JCS00027) should be used as the 8 pin connector. • Unless the connection between the 8 pin connector and data cable is correct, correct data will not be obtained. (2) Connect the 8 pin connector to J4 (EXT1) on the rear panel of the display unit. EXT2 GPS EXT1 Electromagnetic compass F1 POWER SC UNIT F2 E J4 Radar display unit rear panel 1 7 2 6 3 5 4 8 Data - Data + 8P connector (black) This completes the cabling of the electromagnetic compass. 240
9.4 Modifications to be Made to the Inboard Power Supply Attention • Be sure to use the correctly rated fuse. In the event incorrectly rated fuse is used, this may cause breakdown in the equipment. • Make modifications as shown below based on the inboard power supply. (Fuse for 24V is incorporated upon shipment of the equipment) 1. Display unit Fuse rating F1 F2 Inboard power supply Rating JRC Code Rating JRC Code DC12V 6.3A 5ZFAD00336 10A 5ZFAD00539 DC24/32V 3.15A 5ZFAD00227 5A 5ZFAD00364 2. Scanner unit No modifications need to be made with respect to the scanner unit. 241
