Frequently Asked Questions - Analog Audio Balun MuxLab

What is the maximum distance for 720p video transmission?

The maximum distance for 720p (and 1080i) video is 500 ft (152 m) when using Cat5e/6 UTP/STP cable.

Can I use this balun for analog audio only?

Yes, the balun supports analog audio transmission over one twisted pair. You can use it for audio only, but note that the device also carries video; if you only need audio, you can leave the video pairs unconnected.

What type of cable is required?

A Cat5e or Cat6 UTP/STP cable with 24 AWG solid copper wire, 100 ohms impedance, and maximum capacitance of 20 pF/ft is required.

How do I connect the baluns?

Connect one balun to the video source (e.g., DVD player) and the second balun to the display. Use a RJ45 terminated Cat5e/6 cable between the two baluns. Ensure straight-through wiring (Ring to Ring, Tip to Tip) as the device is reverse polarity sensitive.

What is the pin configuration for the RJ45 connector?

The pin assignment is: Red (Pr) on pins 7(R) & 8(T), Green (Y) on pins 3(R) & 6(T), Blue (Pb) on pins 1(R) & 2(T), and Analog Audio on pins 4(R) & 5(T). Follow the EIA/TIA 568A/B standard.

What should I do if there is no video?

Check cable continuity between baluns, ensure video equipment is powered on, and verify that connections are correct. If using analog audio, ensure the audio pairs are not swapped with video pairs.

What causes unusual colors in the video?

Unusual colors are often caused by reversed polarity. Verify that the wiring is straight-through (Ring to Ring, Tip to Tip) and that the pairs are not swapped.

How do I fix audio phase cancellation?

Audio phase cancellation is usually due to reversed wires on the audio pair. Ensure that the tip and ring connections are consistent (straight-through) between the two baluns.

Is the balun powered?

No, the Component Video/Analog Audio Balun is a passive device that does not require external power. It relies on the signal from the source equipment.

What is included in the box?

Each balun unit is sold separately. A pair is required for operation. The box typically contains one balun (either 500052 or 500053) and a quick installation guide.

Component Video / Analog Audio Balun 500052, 500053

Quick Installation Guide

Overview

The Component Video/Analog Audio Balun (500052, 500053) allows one component video (YPbPr or RGB) signal and one Analog Audio signal to be transmitted via a cost-effective unshielded twisted pair (UTP) cable.

Used in pairs, the Component Video/Analog Audio Balun supports 480i/p, 720p and 1080i/p resolution for hi-definition (HDTV) video applications.

The product allows four coaxial cables to be replaced by one Category 5E/6 twisted pair cable allowing standard structured cabling techniques to be used for more efficient cabling.

Installation

One (1) pair of baluns is needed to complete one component (YPbPr/RGB) connection via Cat 5E/6 twisted pair. To install the baluns, perform the following steps:

1. Identify the pin configuration of the baluns. Three (3) twisted pairs are required for video and one (1) twisted pair is required for optional analog audio. The pin configuration follows the EIA/TIA 568A/B standard. The Component Video/Analog Audio Balun is reverse polarity sensitive. Please ensure that wiring is straight-through (Ring to Ring, Tip to Tip).

1. Plug one (1) balun into the component video coaxial cable output of the video source according to the color code of the RCA cable leads.

1. Plug the second balun into the component video coaxial cable input of the video screen or receiver at the remote end.
2. Complete the connection between the two baluns, using standard Cat 5E/6 twisted pair cable and connecting hardware, terminated on RJ45 plugs at both ends. Ensure that there are no split pairs or taps.
3. If analog audio is to be connected (optional), connect an RCA lead between the balun and the analog audio equipment at both ends.
4. Power-on the component video equipment. Check the image quality and refer to the troubleshooting table below if the image quality is unsatisfactory. The following diagram shows a typical installation.

Troubleshooting

The following tables describe some of the symptoms, probable causes and possible solutions in respect to the installation of the Component Video/Analog Audio Balun:

Video Symptom Probable Cause Possible Solutions
	No continuity in video link	Verify cable continuity between pairs of baluns.
	Power off Check power supplies of video equipment. No video
	Improper connection and/or swapped pairs	Check that baluns are connected to correct video inputs and outputs.
Unusual colors Reversed polarity		Check wiring and ensure straight-through polarity.
Background pattern EMI interference		Identify possible radiating frequency sources (i.e., wireless LANs, switching power supplies). Try to isolate them from the video connection. Use shielded twisted pair grounded at both ends.
Smearing Exceeded distance		Verify cable grade. Use higher grade cable if necessary.
Weak contrast	Exceeded distance	Verify cable grade. Use higher grade cable if necessary. Increase contrast on monitor.
	Unusual link attenuation	Verify cable distance using ohmmeter or cable tester.
Image not stable	Defective link or equipment	Verify video equipment interface integrity.
Horizontal bars moving slowly	Substantial crosstalk between multiple video sources	Consecutively turn off other video sources to determine which video source is the cause of interference.
Snowy picture Distance is near limit		Verify cable grade. Use higher grade cable if necessary. Reduce color intensity at monitor.

Audio Symptom Probable Cause Possible Solutions
Poor audio quality	EMI interference	Check that wiring is not too close to transformers and ballasts.
	Split pair	Ensure that the UTP pairs are not split and that each pair of wires is twisted.
	No power Check your audio system for power.
	Open circuit Check wiring to ensure continuity.No audio
	Defective balun Change baluns for another pair.
Audio phase cancellation	Reversed wires	Check for straight-through wiring.
Audio weak	Distance specifications exceeded	Check DC loop resistance and verify if distance spec is exceeded. Reduce cable length or eliminate high-loss components.
