Mounting the GPS-500 antenna
¼ Note: The GPS-500 antenna is only optional for NRS-1 but mandatory for NRS-2.
• It is not recommended that the GPS antenna is mounted up a mast where the motion of the vessel will
cause the antenna to swing and potentially reduce the accuracy of the GPS position.
• Do not mount the GPS antenna within 1 m of a transmitting device.
Mount the GPS-500 externally to either a (A) pole or (B) hard surface then run the cable to the Blackbox. In
all cases, ensure the selected location enables the antenna to have a clear, unobstructed view of the sky.
( A ) Pole ( B ) Hard surface
¼ Note: To pole mount the external GPS-500 antenna, you will require a 1-inch 14 TPI thread pole:
• Screw the pole adapter onto the threaded portion of the pole.
• Feed the cable attached to the GPS antenna through the adapter and pole.
• Mount the pole into position.
• Fit the GPS antenna to the pole adapter using the 2 small screws.
To surface mount the external GPS-500 antenna, select a flat clean surface area that has a clear view of the
sky. Mount the antenna using the supplied gasket and the 2 small screws:
• Mark and drill the 2 mounting holes and a further hole if necessary for the GPS cable.
• Install the gasket by firstly threading the attached cable through the center of the gasket.
• Screw the GPS antenna to the mounting surface.
• Run the GPS cable to the Blackbox:
• Route the cable to the Blackbox, adding any necessary extension cables.
• Connect the cable from the GPS antenna to the GPS connector (SMA) on the Blackbox as shown
below.
Wiring guidelines
Don’ts:
• Do not make sharp bends in the cables.
• Do not run cables in a way that allows water to flow down into the connectors.
• Do not run the data cables adjacent to radar, transmitter, or large/high current carrying cables or high
frequency signal cables.
• Do not run cables so they interfere with mechanical systems.
• Do not run cables over sharp edges or burrs.
