SCART / Péritel Balun 500060, 500061 Quick Installation Guide Overview The SCART/Péritel Balun allows a single composite or S-Video signal plus two (1) analog audio signals to be transmitted via an unshielded twisted pair (UTP) cable in the European SCART/Péritelvision/Euroconnector environment. The SCART/Péritel Balun operates as a transmit/receive pair and features two (2) models: The 500060 and 500061. The 500060 is connected to the transmit side (source) and the 500061 is connected to the receive side (screen).
Installation
Troubleshooting
To install the SCART Balun, perform the following steps:
The following tables describe some of the symptoms, probable causes and possible solutions in respect to the installation of the SCART/Péritel Balun:
Caution:
Do not attempt to open the housing. There are no user-serviceable parts inside the SCART Balun. Opening the unit will void your warranty.
1.
Turn off power and disconnect the audio-video source and monitor.
2.
Make certain that modular outlets and cross connects to which you will connect the SCART Balun are configured properly and labeled appropriately to identify the circuit.
Caution:
Do not connect the SCART 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.
Video Symptom Probable Causes No continuity in video link No video
Power off Improper connection and/or swapped pair
Unusual colors
Reversed polarity
Background pattern EMI interference
3.
Verify that the desired twisted pairs are not being used for other LAN or telephone equipment.
Smearing
4.
The SCART Baluns operate as a transmit/receive pair. The 500060 is connected to the SCART source and the 500061 is connected to the SCART monitor.
Weak contrast
5.
Connect the 500060 to the SCART source (i.e., DVD player or satellite receiver).
6.
Connect the 500061 to the SCART receiver (i.e., audio-video monitor, plasma screen or projector).
7.
Connect a 4-pair Cat 5E/6 cable between the two SCART Baluns following the TIA 568 (A or B) wiring standard as shown in the diagram below.
Exceeded distance Exceeded distance Unusual link attenuation
Image not stable
Defective link or equipment
Horizontal bars moving slowly
Substantial crosstalk between multiple video sources
Snowy picture
Distance is near limit
Audio Symptom Probable Cause EMI interference Poor audio quality Split pair
8.
Power on the audio-video equipment at both ends and adjust the monitor image and audio levels to the desired settings.
No audio
Weak Audio
Power-off Open contact Defective Audio Balun Exceeded distance specifications Lower grade UTP cable is introducing high signal losses
Possible Solutions Verify cable continuity between pairs of baluns. Check power supplies of video equipment. Check that baluns are connected to correct video inputs and outputs. Check wiring. Ensure straight-through polarity. Identify possible radiating frequency sources (i.e., wireless LANs, switching power supplies) Try to isolate them from the video connection. Use STP cable grounded at least on one end. Verify cable grade. Use higher grade cable Verify cable grade. Use higher grade cable if necessary. Increase contrast on monitor. Verify cable distance using ohmmeter or cable tester. Verify video equipment interface integrity. Consecutively turn off other video sources to determine which video source is the cause of interference. Verify cable grade. Use higher grade cable if necessary. Reduce color intensity at monitor.
Possible Solutions Check that wiring is not too close to transformers and ballasts. Check if the UTP pairs are split and correct. Each signal pair must be twisted. Check power supply. Check wiring to ensure continuity Change Audio Baluns for another pair. Check DC loop resistance and verify if distance spec is exceeded. Reduce cable length or eliminate high-loss components. Use signal repeater for extended distance. Replace cable by higher grade.
