Intelix AVDA-8-F - Manual (Page 2)

2. Connect the appropriate Intelix video Baluns to the audio/video source and destinations.
The AVDA-8 supports up to two video and two audio channels. Therefore, the distributor
will work in conjunction with Intelix V1, V1-ST, V1A2, V2A2, and SVA2 Baluns. 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 AVDA-8 must be within maximum distance specs of the controller and of each
terminal (see Specifications section). Note that every connection is equivalent to 10' of cable
and must be included in the maximum cable length calculation. 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 feet of 24 AWG cable should give a reading of approximately 26 ohms (52 ohms if you
are measuring at one end with the opposite cable ends shorted).

The AVDA-8 must be kept away from sources of radio-frequency or electromagnetic
radiation:
a) 5" from power lines of 2 kVA or less
b) 12" from fluorescent lighting and power lines between 2 and 5 kVA
c) 36" from power lines greater than 5 kVA
d) 40" from transformers and motors
Best performance is achieved using home-run cable. Do not use flat cable (i.e., cable that is
not twisted), even for patching with short runs; flat cable acts as an antenna and will pick up
nearby radio frequency interference.
4. Identify the pin configuration of both the video Balun and the AVDA-8. For example, when
using an Intelix V1A2, the modular cable must use straight through polarity.
