1.1.1.2 Power Supply Module
The VDR-1
00G2 has the option of being powered by either AC or DC supply (must be chosen at time of
order as it is not field configurable):
 The AC input range is 85-264V, 47-63Hz.
 The DC input range is 19-28V.
 The output of both supplies is 27.6VDC, which is the normal operating voltage of the VDR.
The power supply also acts as a battery charger for re-charging low batteries or maintaining a full charge.
The battery input is reverse polarity protected by a crossbar diode and a replaceable fuse.
1.1.1.3 Power Control Module
The Power Control Mo
dule monitors the power system and communicates the power system status
information to the DMM. It also controls the switching circuitry to transfer the load from the power supply
to the batteries.
1.1.2 Data Acquisition Unit (DAU)
The Data Acquisition Unit (DAU) is an optional component that can house up to four (4) main data
acquisition modules:
 Audio Module
 Video Module
 (2) NMEA Modules
These modules are used to capture ship information and output this acquired data through an Ethernet
port, transmitting it to the DPU for processing and storage.
