2.Check the Cat-5 wire conﬁgurations. Use an RJ-45

cable tester.

"Picture is fuzzy or edgy."

1.Adjust the Cable Compensation control on the BVR-

25. This compensates for the increased capacitance on

longer Cat-5 cable runs and sharpens the video image.

2.Conﬁrm the cable length. It is important to note that

the BVR-25 was designed for cabling no longer than

1000' for standard component video or 300' for a High

Deﬁnition signal. Cat-6 wiring will give the longest,

best picture.

"There is hum in the audio signal."

1.Verify that the Cat-5 cable is properly terminated on

both ends.

2.Make certain that the system is wired with CAT-5

twisted-pair cabling.

3.Make certain there are not any cuts, pinches, or sharp

twists in the wiring, allowing a conductor to short to

ground (i.e. shield, conduit, cold water pipe, plenum).

"No +12 volt output"

1. Measure output with voltmeter.

2.Conﬁrm amperage required for automation system.

Install relay if necessary.

3.The video signal feeding the BVR-25 is too low or un-

calibrated. Re-adjust gain and calibration controls.
