Installation
You may wish to consult with a qualified custom electronics installer if you are inexperienced with UTP wiring and cable
termination. You should be familiar with Cat 5e/6 cable termination tools, techniques, testing, and wire routing principles.
1. Assembling Expanders. Follow these steps if you are installing Models 1172BK, 1176BK or other expanders with
your AVM-562 or AVX-562. Otherwise, skip to Step 3.
All video, audio, and communication signals between sources, Cat 5 outputs, and audio system outputs travel through
the special ribbon bus cable. The AVAtrix normally ships with a 4-port bus cable, leaving two open ports for expand-
ers. If you need to add more than two expanders, order AVM-562E or call Audio Authority Technical Support.
a. Lay the Model AVM-562 upside down on a protective surface, such as a terry cloth towel.
b. Remove the four feet and the bus access covers (save them and their attaching screws).

c. Gently feed the loose end of the bus cable out of the bus ac-
cess opening.
d. Plug the next connector into the port visible through the ex-
pander case opening—apply enough pressure with fingers or
a plastic tool to assure that the plug is completely seated.
e. Turn the next product to be stacked upside down (e.g. Model
1172BK or 1176BK), thread the bus cable through its bus
access openings, and engage its four threaded studs with the
four threaded holes in the Model AVM-562 formerly occupied
by the feet.
f. Tighten the hex head screws in the bottom of the stacking
product in sequence a few turns each, until they are all snug.
g. Carefully plug the ribbon cable into the bus port. Continue
this stacking procedure until all units have been assembled.
View the bus through the bus port to be sure all plugs are fully
seated.
h. After plugging the last connector of the bus into the bottom
unit, carefully tuck any excess cable into the empty space
inside the last unit. Be certain the back of the connector does
not contact the metal case. To disconnect a bus plug, squeeze
the side latches.
i. Install the bus port cover and feet you removed from Model
AVM-562 onto the bottom unit and turn the stack right side up.
2. Addressing and Initial Testing.
a. Set the Address dial on each Model 1172BK
and/or 1176BK: set the upper-most Model
1176BK address to “B”, the next one to “C”,
and so on. The AVM-562 Cat 5 output row is
permanently addressed “A”. Follow 1172BK
manual for addressing 1172BK.
b. Temporarily plug in the power supplies of
all units to a plug strip so that you can turn
them all on at one time. The opening screen
on the Model AVM-562 display indicates that
the unit is powered and shows the number
of expanders that have been recognized.
If this number is different from the number
actually present, look for the bus not being
fully plugged into a unit or a unit incorrectly
addressed.
Note: If you are installing expanders on Model
1156 or 1166 the address scheme is different.
Refer to the AVX-561 or AVX-661 manual.
