CCTV Power-Thru Balun (500024, 500029)
Quick Installation Guide
Introduction
The VideoEase CCTV Power-Thru Balun allows video and remote power to be
transmitted via one 4-pair Cat 5 cable, thus eliminating the need to install multiple
cables for more efficient cabling. There are two models: 500024; with modular RJ45
connector and 500029; with screw terminal connectivity. The CCTV Power-Thru
Balun may be used in pairs or in conjunction with other MuxLab CCTV baluns such
as the 500000, 500009, 500015, 500022 and 500023.
Installation
Pre-Installation Checklist:
Note: For regulatory reasons, use of a Class II power supply is
recommended and may be required with the use of this product in some
regions.
1.
Ensure the CCTV equipment and remote power supply is turned off.
2.
One (1) twisted pair is required for the camera video signal. Three (3) twisted
pairs are required for remote power.
3.
Verify that the cable length is within MuxLab specifications. The maximum
distance for video and remote power may be determined by consulting the
product specifications or the CCTV Balun Application Guide available on-line
at
www.muxlab.com/support
.
4.
If the 500024 is being used, identify the pin configuration of the balun by
checking the product label or the specification section of this installation guide.
5.
If the 500029 is being used, remove the balun cover with the help of a small
flathead screwdriver. The screw terminals are labeled “R/T” (Ring/Tip) and
“+/-“ for video and remote power respectively.
