Installation
One pair of HD-SDI Baluns is needed to complete one connection via UTP cable. To
install the HD-SDI Balun, perform the following steps:
Caution:
Do not attempt to open the housing. There are no user-serviceable parts
inside the HD-SDI Balun. Opening the unit will void your warranty.
Do not connect the HD-SDI Balun to a telecommunication outlet wired
to unrelated equipment. Making such a connection may damage the
equipment and/or the balun. Please ensure that all wiring is “straight-
through” twisted pair.
1.
Verify that the desired twisted pairs are not being used for other LAN or telephone
equipment.
2.
Connect the Balun (500701) to the HD-SDI video port of the source equipment
(
i.e.
, HD camcorder or HD-CCTV camera).
3.
Connect a dedicated Cat5e/6 cable between the source-side HD-SDI Balun and the
receiver-side HD-SDI Balun.
4.
At the destination point, connect the HD-SDI Balun to the HD-SDI receiver (i.e.
monitor or DVR).
The following diagrams show a couple of typical configurations.
Troubleshooting
The following tables describe some of the symptoms, probable causes and possible solutions regarding
the HD-SDI Balun:
Video Symptom
Probable Cause
Possible Solutions
No video
No continuity in video link
Verify cable continuity between pairs of
baluns.
Power off
Check power supplies of video equipment.
Improper connection and/or
swapped pair
Check that baluns are connected to correct
video inputs and outputs.
Part of picture
missing or
intermittent.
Missing frame or
freezing.
Exceeded distance
Verify cable length and grade. Use higher-
grade cable if necessary.
SDI is in 3G mode (1080p). Change to lower speed (max 1080i).
Unusual link attenuation
Verify cable distance using a cable tester.
EMI interference
Try turning off (or move) nearby wireless
LANs, switching power supplies, radio
transmission to see if problem disappear.
Image not stable,
noise, incorrect color
or sound.
Defective source or
receiving equipment
Try swapping source/monitor equipment or
verify video equipment interface integrity.
SDI is in 3G mode (1080p). Change to lower speed (max 1080i).
