Video Input Module - American Dynamics MegaPower 3200 Installation Manual

Video Input Module

Note: VIMs are installed, configured, and labeled
either in the factory or by a technician in the field.
As directed by the keyboard, an AD2016AVIM
(Figure 10) selects which one of up to 16 video
inputs is used for display (primary switch). The video
path is shown on Figure 11.
• Factory set jumpers on the VIM circuit board
identify the video input and output range for the
VIM.
• A camera symbol identifies the video inputs.
• A label next to the BNCs shows the input number
and a label at the top of the VIM shows the lowest
camera input for that VIM according to its location
within the bay(s).
A VIM can have one of four rear panels:
• AD2016AVIM-1: A VIM-1 has 16 rear panel BNC
connectors that receive video from a camera and
send it to the plug-in circuit board configured for
the video input/output ranges. The video is then
sent to the back plane.

• AD2016AVIM-2 and AD2016AVIM-3: As shown in
Figure 12, VIM-2 and -3s work together to create
16 video inputs. Each has eight rear panel video
input connectors to receive video input. The video
is sent to the plug-in circuit board factory
configured for the video input/output ranges and
then to the back plane.
- The VIM-2 has a 34-pin ribbon coax cable
connector that receives eight video inputs from
the VIM-3 in addition to its own eight inputs (for
a total of 16). The ribbon connector also sends
eight inputs from the VIM-2 to the VIM-3.
- The VIM-3 has two 34-pin ribbon coax cable
connectors: an IN connector to receive eight
video inputs from a VIM-2 and to send its own
eight inputs to the VIM-2 (for a total of 16), and
an OUT connector to expand its own eight
inputs and the eight inputs from the VIM-2 to
more monitor levels via a VIM-4.
• AD2016AVIM-4: Has two 34-pin ribbon cable
connectors (Figure 12):
- An IN connector to receive the 16 video inputs
from a VIM-3.
- An OUT connector to expand the 16 inputs to
more monitor levels.
- The OUT connector is terminated with 75
ohms if the last in a series.
