Furniture Mounting
2.
Hold the unit with the attached brackets against the
underside of the table or other furniture. Mark the location
of the screw holes of the bracket on the mounting surface.
3.
Drill 3/32" (2 mm) diameter pilot holes, 1/4" (6.3 mm) deep
in the mounting surface at the marked screw locations.
4.
Insert #8 wood screws into the four pilot holes. Tighten
each screw into the mounting surface until just less than
1/4" of the screw head protrudes.
5.
Align the mounting screws with the slots in the brackets
and place the unit against the surface, with the screws
through the bracket slots.
6.
Slide the DA slightly forward or back, then tighten all four
screws to secure the unit in place.

Video Output connectors — Connect up to two (IN3212) or
2
four (IN3214) composite video output devices, such as
projectors, VCRs, or monitors, to these female BNC connectors.
For an IN3214 configured in split mode and distributing
S-video, Outputs 1 and 2 output one video plane (Y or C)
and Outputs 3 and 4 output the other plane (C or Y).
Input 1 connector — Connect a composite video input or
3
(for the IN3214 only) an S-video Y or C input, such as from
a DVD player or a VCR, to this female BNC connector.
Loop-out/Input 2 connector —
4
Default configuration — In the factory default
configuration, this female BNC connector is not used.
Buffered loop-through — To provide a buffered loop-
through signal, the internal jumper settings must be
changed (see the jumper table on page 5).
Split mode (IN3214 only) — When the IN3214 is
configured for split mode, this female BNC connector
provides an input connection for a second signal source,
either composite video or an S-video C or Y input. See
Normal and Split Mode (IN3214 Only) for more details.
Gain control — Use a tweeker to adjust the amount of
5
amplification that is added to the video signal. The
adjustment range, assuming a 1.0V input, is from 0.7V (30%
decrease) to 1.4V (40% increase).
Peak/Sharpness control — Use a tweeker to adjust for the
6
best sharpness.
