Condensed Bay
The condensed bay (Figure 8) has two separate
video switching buses that have 16 lines each. A
condensed bay:
• Is like two bays in one with two separate back
panels and two sets of four VIMs and four VOMs
• Can support up to 128 camera inputs and 32
monitor outputs.

CAUTION: A VIM or VOM can plug into
any unused slot as long as it is properly
configured. However, to install the system
efficiently and to facilitate troubleshooting,
ALWAYS install:
- VIMs in series beginning from the right-
most slot as viewed from the rear of the
bay.
- VOMs in series beginning from the left-
most slot as viewed from the rear of the
bay.

Control Inputs

Referring back to Figure 4.
AD Data Line
A separate MegaPower CPU (central processing
unit) and keyboard control the matrix switcher via an
AD data line. This line:
• Plugs into the DATA LINE IN BNC on the rear
panel of the bay.
• Sends 64 ADDL switch packets of information to
the switching bays that includes camera and
P/S
monitor selection, titles, and time and date.
• Controls up to 13 camera groups (3200 video
inputs) and up to four monitor levels (64 video
outputs).
IN
IMPORTANT! For dome PTZ control, each
additional four camera groups (1024 video inputs)
requires a separate AD data line (Table 2).
IN
• Can loop from bay-to-bay.

Synchronization Pulse
An external vertical synchronization pulse used to
synchronize cameras connects to the EXT. SYNC IN
BNC on the rear panel of the bay. This pulse can
loop from bay-to-bay.
