SharpZ3 navigation expansion module connections - SharpZ3 | SharpOS 13.4

With the navigation expansion module, the SharpZ3 system can add precise location information to license plate reads and can ensure that the patrol vehicle is accurately displayed on maps in Genetec Patroller™.

VSS connections

Odometry sensor connections

	Component	Description
A	Navigation expansion module	The navigation expansion module adds precise positioning to the SharpZ3 system.
B	Satellite navigation antenna	The GNSS satellite navigation antenna is connected to the base unit and works with the odometry inputs to provide precise georeferencing for the vehicles associated with the plate reads. For more information on which satellite navigation hardware to install, see Satellite navigation hardware options. NOTE: Connecting the satellite navigation antenna to the navigation expansion module provides more accurate location information than connecting an antenna to the in-vehicle computer.
C	Reverse signal	The SharpZ3 system is usually connected to the vehicle’s reverse signal by tapping the reverse lights.
D	VSS or odometry sensor cable connection	Connect the hardware to the base unit as shown in the diagram. NOTE: The wire that connects to the CGND pin is the drain wire from the sensor cable.
E	VSS signal	You can tap the VSS signal from the vehicle's power-train control module (PCM). For more information, see the vehicle's electrical schematics documentation. NOTE: Some newer vehicles and electric vehicles do not include a VSS or OSS.
F	Odometry sensor	If the VSS signal from the vehicle is unavailable, you can install an odometry sensor. In general, a VSS provides more ticks per wheel rotation, resulting in more accurate odometry. For more information on the odometry sensor, see Installing the odometry sensor.
