Figure 5: Heavy Vehicle Expansion Unit (PROD0161)
The Heavy Vehicle Expansion Unit provides the ability to easily expand the number of
cameras and RF Units from the standard 2 channels supported by the Display Unit up to a
maximum of 6 channels.
Features:
IP 54 rated enclosure
Provides Camera Unit & RF Unit expansion up to 6 units maximum with the Display
Unit
4 local camera inputs (in addition to 2 camera inputs on Display Unit) – can connect RF
Units to Camera inputs for upgrade to RF tagging capability (CAS-CAM/RF
®
)
4 auxiliary inputs (opto isolated) (e.g. reverse & forward signals)
2 switched contact outputs (voltage free) (e.g. reverse alarm circuit)
RS-232, RS-485 & CAN interfaces
Wide operating power supply range (10–30 VDC, 50W max) also powers Display
Unit
(Note: The Display Unit, Expansion Unit, Camera Units and RF Units can be
permanently powered from the Heavy Vehicle battery with the Display Unit screen
powering down after a preset timeout period when the vehicle is not in forward or
reverse gear (if enabled). This function conserves battery life and enables the RF
tagging to still be active when the vehicle is unattended for the benefit of other vehicles.
Camera only installations (CAS-CAM
®
) are powered from the vehicle auxiliary / ignition
circuit.
Input power provided from vehicle electrical distribution board (10–30 VDC, 50W max)
Rugged aluminum construction
Typically located within 10 metres of Display Unit
