To acquire NMEA data such as position information from the GPS equipment of JRC or other maker's GPS
equipment by acquiring azimuth data only from JLR-20/30, connect azimuth data only using the dedicated
CFQ-5469 cable that is shown in the above diagram. For the position information, connect the GPS
equipment as described in Section 3.6 without using the cable from JLR-20/30 labeled with "GPS".
1.2) Procedure for not using a dedicated cable
When receiving azimuth information data from the GPS compass, connect the necessary signal lines to
the attached NMEA data connector P5 (for J5) LTWBD8BFFA-LL7001 using the following diagram as
the reference.
Signal name GPS compass connector side JMA-5300MK2 side
Compass data input + Disconnected Disconnected
Compass data input - Disconnected Disconnected
Compass data output + Sensor throw SD-A (3) NSKRX +
Compass data output - Sensor throw SD-B (4) NSKRX -
GND Disconnected Disconnected
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)
The above-mentioned connections are available only for receiving bearing data from JLR-20/30. About
how to receive position information, refer to section 3.6.
2) Setting GPS Compass (JLR-20/30)
Set the following information with the GPS compass.
Data output format=NSK
Refer to the manual for the GPS compass for the detailed setting method.
