VOMs: A VOM, as directed by the keyboard, acts as
a secondary switch by selecting which of its four
video outputs (A, B, C, or D) connects to the video
input selected by the VIM of a camera group. A
VOM:
• Is installed in the bay for the highest camera
group.
• Comes in three types: VOM-1 supports four
camera groups, VOM-3 supports eight camera
groups, and VOM-4 supports 13 camera groups.
IMPORTANT! The highest camera group is
always received internally from the bay the VOM
resides. All other camera groups are received
externally from other bays via VOM cables. The
video path of a video input is shown in Figure 7.
• Provides text overlay to the video signal.
• Comes factory configured for the monitor levels it
will support. However, the installer must configure
the VOM (using jumpers) if they are replacing a
defective one or adding one to an existing system.
Standard vs. Condensed Bays
A switching bay can be an AD2010 standard bay or
AD2020 condensed bay.
Standard Bay
The standard bay (Figure 5) contains a video
switching bus along an internal backplane that has
16 lines.
Note: A standard bay is considered "mixed" when it
contains both VIMs and VOMs, or "dedicated" when
it contains only VIMs or VOMs. VOMs are installed in
only in the bay for the highest numbered camera
group.
