The HD-SDI Balun (500701) allows one SDI signal to be transmitted up to 150 ft (45m)
via CAT cable at HD resolution (720p, 1080i) in a point-to-point configuration. The
HD-SDI Balun supports transmission of uncompressed, un-encrypted digital video
(optionally including embedded Audio and/or Time Code) within television facilities
and between professional video equipment. Two identical balun are required.

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 higher­grade 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).

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 “straight­through” 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.
