JRC GPS124 Instruction Manual page 6

When the GPS124 is connected to directly connectable GPS navigation equipment, 12 V
from the equipment to the GPS124. In this case, connect the 6-pin connector to the plug where the
GPS label is attached on the rear panel of the equipment.
3.4.2 Connection to Navigation equipment that cannot be connected directly
Connect it taking care about the polarity of the power supply.
The faulty wiring might damage the GPS124.
GPS 124 is designed for the power supply of 12/24VDC.
If the power supply of over 40V is fed to the equipment,
It might be damaged.
Normally, the 12/24VDC power is supplied out of the DC power switchboard or main battery.
As the normal current of the equipment is approximately 0.1A, it is recommended using a fuse not
exceeding 2A in the power line.
When the initialization is not provided, leave pin 5 open.
When the DGPS correction data is not applied, pin 6 open.
Fig. 3.3 shows the connection for NMEA 0183 data output with the equipment that cannot be
connected directly.
