Monitor Outputs

The TC8272 Series provide a single video output which
will display a quad view of the video inputs.

The TC8276 Series provide two monitor outputs. The
VIDEO OUT is a full function output providing Sequence,
Quad, Full View, Freeze, Alarm, and Video Loss
operations. The QUAD VIDEO OUT provides a quad
view, quad view with freeze, and full view with zoom­freeze operations.

The monitor outputs must be terminated into a 75 ohm
load. If the monitor output line is looped through monitors
or other equipment, be sure the monitor terminations are
set to Hi-Z. Only the last unit on the line should have its
termination set to 75 ohm.

Camera Phase/Update Rate

The TC8272 Series and TC8276 Series achieve a real­time update rate (30 frames-per-second) when they are
used with line-locked cameras that have a phase error of
less than 5 degrees. This can be achieved by adjusting
the phase adjustment on the individual cameras. The
phase adjustment should be made before power is
applied to the VidQuad
made after power has been applied to the unit, the unit
should be momentarily disconnected from the power
source then reconnected to the power source to
synchronize the unit with the cameras. The unit-to­camera synchronization will automatically be initiated
when a camera is connected to an unused video input. If
this procedure is not followed, or if the cameras are not
line-locked together with ± 5 degrees phase, the update
rate of the unit will be one-half real-time, or 15 frames­per-second.

CAUTION: The following special setups
should only be done by an authorized service
center or installer.

Quad-Sequence Enable

The quad screen will be sequenced with the four full­screen video inputs with resistor R259 installed. If R259
is removed, the quad screen will not be included in the
sequence. As factory default, the unit is shipped with
R259 installed. The cover must be removed to access
R259. Refer to Cover Removal and Dip Switch and

Resistor Locations - TC8276 Series illustrations.

Video Loss Defeat

Internal DIP switch S201 can be used to defeat the video
loss function of the video inputs. The cover must be
removed to access S201. See Cover Removal and Dip
Switch and Resistor Locations - TC8276 Series
illustrations. This is used if less than four cameras are to
be connected to the unit. The factory default is video loss
enabled for all four video inputs.

When all four cameras are used, all four positions of the
S201 should be open (OFF).

When three cameras are used, they should be
connected to video inputs 1-3, and S201 position 1
should be closed (ON) to defeat the video loss for 1
video input (4).

When two cameras are used, they should be connected
to video inputs 1-2, and S201 position 2 should be closed
(ON) to defeat the video loss for 2 video inputs (3, 4).
