Connecting the Power
1.
Run a three-conductor 16 AWG cord from the vehicle power, electrical ground, and ignition
source locations to the recorder.
Note:
Adding inline, fast-blow fuses to the main power and ignition inputs is recommended.
2.
With the vehicle power off, connect to the vehicle power and ignition sources.
Contact the vehicle manufacturer for information on connecting to the vehicle power source.
3.
At the recorder, remove the P1/P1A connector.
4.
Terminate power, ignition, and ground wires to the proper terminal of a mating Molex
connector.
5.
Connect the mating Molex connector to the J1 connector on the P1/P1A harness.
6.
Before reattaching the P1/P1A connector to the recorder, turn on the vehicle power and use a
voltmeter to check each Molex terminal for proper voltage and polarity.
Main power and ignition voltages should be nominal 12 or 24 VDC.
Note:
MobileView 7000 Series recorder supports nominal SAE vehicle voltages of 12 and
24 VDC.
7.
After confirming voltages and polarities are correct, remove vehicle power, plug the P1/P1A
connector into the recorder, and tighten the retaining ring.
8.
Check all connections before starting vehicle power.
Battery disconnect systems
Many vehicles incorporate a source disconnect device, also called a battery disconnect or knife
switch. The device removes power to noncritical systems during routine maintenance or to stop long-
term battery drain. When the recorder is connected to a device, it is subject to immediate and
uncontrolled loss of power. Uncontrolled power loss can negatively affect expected system
performance. The recorder avoids this by implementing an internal UPS, designed to keep the system
operational for 3-7 seconds after all power is lost. This allows the device plenty of time to stop any
open processes and close files in preparation for power loss.
P2 harness connections
Harness P2 applies to the 7001 recorder. The P2 harness connects three multi-pin screw-down type
connectors to the circular P2 connector. This delivers dedicated termination points for external
devices. Common and specific usage of each termination point is provided in the following table.
