Data Buffer Module - American Dynamics MegaPower 3200 Installation Manual

Data Buffer Module

The AD2010DB-01 data buffer (Figure 14) is used
when video must be amplified and sent externally to
a VOM(s) in another bay (see Figure 15).
The data buffer:
• Amplifies video for up to 16 video inputs (but does
not provide a text overlay).
• Always inserts into the slot adjacent to the power
supply.
• Is labeled on its rear panel to reflect its camera
group when it is used to route video to VOMs in
another bay.
• Is not used for video coming internally from VIMs
in the bay the VOM resides. When the data buffer
is not used, a "Test/Expansion" label replaces the
output numbers on the rear panel.
• Filters the data line, if so configured. Filtering
reduces the number of data line switching packets
to improve switching speed in bays having only
VIMs. Filtering is rarely used and is not available
in expanded systems having over 1024 cameras.
Preconfigured systems have filtering set to OFF.
Note: An AD2010DBVL data buffer module with
video loss detection can be used instead in bays
used for the highest monitor level (see Appendix A
for description). When video loss detection is
desired, an RJ-45 jack used for communication with
the CPU replaces one BNC, reducing total video
outputs by one. See Appendix A.
