4.0 CONNECTING THE HARDWARE
Please study the drawings below and become familiar with the inputs, outputs
and control locations on the AVT-8120.
AVT-8120 Front Panel
The front panel of the AVT-8120 contains the product’s control switches and On
Screen Display (OSD) menu access.
AVT-8120 Rear Panel
On the AVT-8120, the power connector, video in connectors, 75Ωdip switch
selector for video termination, monitor out, power on and off, VCR in and out plus
the alarm connector are located on the rear of the unit.
5.0 OPERATING THE AVT-8120
First, prepare the alarm cable if you intend to utilize this capability of the unit.
(Consult the information on the specification page [page 5] to determine the
wiring diagram and the voltage and current specifications used for the alarm
circuits.) When finished, connect the alarm connector to the AVT-8120 and then
to the external alarm devices.
Next, attach up to four cameras to the unit’s video inputs. If you are not looping
the video inputs to individual video monitors, use the 75Ωvideo termination dip
switch to terminate the inputs. Attach a video cable from the video output jack to
your quad split monitor. Connect the VCR in and out cables. Next, connect the
supplied AC adaptor to the unit and then to the AC power source. Turn on any

8
additional monitors and the cameras. At this time, an image should be present on
your master monitor.
Looking at the front of the unit, you’ll see several control switches. The switches
work in concert with one another in some instances and the table below will help
you understand the functions utilized by the AVT-8120’s controls.
The table below shows the various possible modes in the left most column and
the balance of the columns show what happens when you press the various
buttons when in the selected mode.
At this time, become familiar with the different types of operating modes by
pressing the various keys.
Because there are several modes and adjustments possible, the task appears
daunting at first but once you start exploring the various functions it will become
clear very quickly.
Look at the top row – the Normal Mode row. If you are in the Normal Mode,
pressing the various buttons (Shift, Auto/Quad. The Arrow Keys, VCR/PIP/Enter

and Menu/Zoom) will perform the functions listed in the boxes beneath the
captions. As an example, pressing the VCR/PIP/ENTER key will cause the unit to
enter the PIP screen display mode. Pressing the Auto/Quad button will return the
unit to the Quad Split mode and so on.
Each mode listed at the left hand side of the table has actions associated with
that mode and those actions are listed in the boxes to the right of the mode.
In addition to seeing changes to the video on the monitor as you change modes,
if you select the Menu Mode (by pressing the shift key and the Menu/Zoom key),
you’ll see the On Screen Display (OSD) appear which will guide you through all
the setup functions.
As an example of how this process works, press the shift key and the
Menu/zoom key. As shown above, this will take you to the Menu Function Set Up
screen on the monitor.

6.0 Troubleshooting
Other than checking for faulty cables, the most common problem would be
becoming confused as to the function of the modes and keys. Re-read the
operational tutorial above to make certain you understand what each button does
for each mode. Make sure the AVT-8120 is connected to a known good monitor
and the camera inputs are present. If not using the camera loop through feature,
make sure the terminator DIP switch is switched to ‘On’ for each input source. If
one input image is acceptable but the other is not acceptable, you should
suspect faulty cables. Swap the cables to determine if the problem also swaps.
After trying the above suggestions should the problem still persist, contact your
dealer for additional suggestions before contacting AV Toolbox’s parent
company, TV One. Please contact TV One via our support website:
http://tvone.crmdesk.com. Create a technical support request on the site and
our support team will respond within a short period of time.
