Installation Procedure

Installation
Follow the steps listed below to install the Audio-Video Hub :
1.
The Audio-Video Hub is polarity sensitive and works in conjunction
with MUXLAB’s VideoEase video baluns. If the Audio-Video Hub
is used with baluns which have a signal polarity opposite to that of the
Audio-Video Hub, then the signal polarity of the cabling between the
hub and the video baluns may need to be reversed. Verify that the pin
configuration of the video baluns match the pin configuration of the
hub. The pin configuration of the hub is conveniently located on the
rear panel.
2.
Connect the appropriate MUXLAB video baluns to the audio-video
source and destinations. The Audio-Video Hub supports up to two
video and two audio channels. Therefore, the Audio-Video Hub will
work in conjunction with the CCTV Balun, Stereo Audio/Video
Balun and 2-Way Audio/Video Balun. Prepare the appropriate line
cords to connect the baluns to the twisted pair cabling system in the
building.
3.
Place the Audio-Video Hub in its final location.
Before connecting the cables keep the maximum cable lengths in
mind. The final location for the Audio-Video Hub must be within
maximum distance specs of the controller and of each terminal (see
Specifications section). These distances assume that the cable used
conforms to the cable requirements given in the Technical Specifica-
tion section of this guide. Note that every connection is equivalent to
10' of cable and must be included in the maximum cable length cal-
culation. If you are not sure of your cable length it can be estimated
by performing a DC resistance test with a digital ohm meter. 1000
