© MuxLab Inc.Connections:1. At the camera side, connect the balun’s coaxial cable lead into the BNC-Fconnector of the CCTV camera.2. At the camera side, connect the balun’s red and black wires to the power inputof the camera.3. If the 500024 is being used, connect a 4-pair unshielded twisted pair cable tothe balun. The cable must be terminated with an RJ45 modular plug. Cross-connection hardware such as wall outlets and patch panels may be used asrequired. The 500024 supports TIA 568A and 568B wiring standards.4. If the 500029 is being used, connect one (1) twisted pair to the “R/T” terminalsfor video. Connect three (3) twisted pairs to the “+/-“ terminals for remotepower , by connecting one wire from each twisted pair to each terminal. Seediagram below.5. Note: The CCTV Power-Thru Balun is reverse polarity sensitive. Whenconnecting the baluns, ensure that “Ring [R]” is connected to “Ring [R]”and “Tip [T]” is connected to “Tip [T]”. Verify that there are no splitpairs or crossed wires.6. At the receiver side (i.e.; DVR side), repeat steps 1 to 4 for the second balun.7. Power-on the CCTV equipment and remote power supply.
