© MuxLab Inc.InstallationOne (1) pair of baluns support four (4) composite video signals or one (1) componentvideo (YPbPr) and one (1) composite video signal via a Cat 5E/6 twisted pair. To installthe baluns, perform the following steps:1. Identify the pin configuration of the baluns. Four (4) twisted pairs are required ifall four (4) signals are transmitted. The pin configuration follows the EIA/TIA568A/B standard. The Quad Video Balun is reverse polarity sensitive. Pleaseensure that wiring is straight-through (Ring to Ring, Tip to Tip).2. At the video source end, connect a Quad Video Balun to the video output using theappropriate number of RCA or BNC cables.3. At the video display end, connect a Quad Video Balun to the video input using theappropriate number of RCA or BNC cables.4. Complete the connection between the two baluns, using standard Cat 5E/6 twistedpair cable and connecting hardware, terminated on RJ45 plugs at both ends. Ensurethat there are no split pairs or taps.5. Power-on the video equipment. Check the image quality and refer to thetroubleshooting table below if the image quality is unsatisfactory. The followingdiagram shows a typical installation.TroubleshootingThe following table describes some of the symptoms, probable causes and possiblesolutions in respect to the installation of the Quad Video Balun:Symptom Probable Cause Possible SolutionsNo continuity in video link Verify cable continuity between pairs ofbaluns.Power off Check power supplies of video equipment.No videoImproper connection and/orswapped pairCheck that baluns are connected to correctvideo inputs and outputs.Unusual colors Reversed polarity Check wiring and ensure straight-throughpolarityBackground pattern EMI interferenceIdentify possible radiating frequency sources(i.e., wireless LANs, switching powersupplies). Try to isolate them from the videoconnection.Use shielded twisted pair grounded at bothends.Smearing Exceeded distance Verify cable grade.Use higher grade cable if necessary.Exceeded distanceVerify cable grade.Use higher grade cable if necessary.Increase contrast on monitor.Weak contrastUnusual link attenuation Verify cable distance using ohmmeter orcable tester.Image not stable Defective link or equipment Verify video equipment interface integrity.Horizontal barsmoving slowlySubstantial crosstalkbetween multiple videosourcesConsecutively turn off other video sources todetermine which video source is the cause ofinterference.Snowy picture Distance is near limitVerify cable grade.Use higher grade cable if necessary.Reduce color intensity at monitor.If you still cannot diagnose the problem, please call MuxLab Customer TechnicalSupport at 877-689-5228 (toll-free in North America) or (+1) 514-905-0588(International).
