3)
Terminal 13 of the P2 terminal block is the normal operation output. Voltage should be observable
on the meter when the BusSecure is recording normally.
Note:
Voltage may vary from +5 VDC to +12 VDC, depending on the type of status indicator installed.
4)
If voltage is not present, remove any wires that are connected to terminal 13 and repeat steps 1
through 4.
5)
Repeat steps 1 through 5 for terminal 15 of the P2 terminal block. On terminal 15, voltage will only
be present under a fault condition and at startup.
6)
If the vehicle power and the DVR’s output of ground are both present at the light, but the light is not
illuminating, it may be necessary to troubleshoot the vehicle wiring or replace the status light.

ECURE CONNECTION BOX AND THE CAMERA
1)
If there is no video displayed, verify on the two-pin Molex camera power connector that 12 VDC is
present.
2)
Verify that the power connection on the camera is intact.
3)
Verify that the power connection on the P1 terminal strip is correct.
4)
Check the integrity of the coaxial cable and the BNC connectors.
5)
Ensure that the BNC connectors at the DVR and camera have not been damaged or pulled apart.

HECK THE INTEGRITY OF THE COAXIAL CABLE
1)
Disconnect the coaxial cable from the camera and DVR connection box.
2)
Meter the coaxial cable by placing a jumper from the center conductor (video) of the BNC to the
outer part of the BNC (ground).
3)
Use a meter on the other end of the coaxial cable to check for resistance by placing one probe on
the center conductor and the other probe on the outer part of the BNC.
4)
Remove the jumper and meter one end of the disconnected coaxial cable. There should be no
resistance.
