Zoom During VCR Playback
To zoom a quadrant in the recorded VCR display on the
MON-A monitor, select that quadrant as the active
quadrant by using the arrow buttons. An asterisk (*) will
indicate the active quadrant. Press ZOOM to zoom that
quadrant to full screen display. Once in Zoom mode, the
arrow buttons will act as Pan and Tilt controls. Press
ZOOM or the QUAD button to return to normal VCR
playback.
The MON-B monitor will continue to display the full VCR
signal continuously. The dual VCR input displays give the
user maximum flexibility to examine VCR playback.
To exit VCR mode: Press VCR.
5.2.8 SEQ Button
Starts or stops sequencing on the MON-A quad displays for
the TC8278 Series only. For full screen sequencing, refer to
Monitor B operation.
Quad Page Sequencing (TC8278 Series Only)
In this mode, the SEQ button may be used to toggle the
sequencing of the two quad pages on and off.
To start sequencing of the two quad pages on the MON-A
output, press SEQ. This will cause a quad display of cameras
1 thru 4 to sequence with a quad display of cameras 5 thru
8, at the quad sequence dwell time.
Note that an active quadrant must not be selected at the
time that quad page sequencing is selected. If there is an
active quadrant displayed on the screen, first press QUAD
and then SEQ to start full quad sequencing.
The quad sequence dwell time is menu programmable
between 1 and 99 seconds.
To stop quad page sequencing, the operator can either press
SEQ or press QUAD. Note that pressing an arrow button
to select an active quadrant during full quad display
sequencing will allow an operator to stop (or re-start) the
sequencing of any one quadrant at a time, as explained
below.
If sequencing is in progress on either monitor, it will be
indicated on-screen on the corresponding monitor(s) by the
indicator "SEQ".
Individual Quadrant Sequencing
(TC8278 Series Only)
The operator can also sequence individual quadrants while
other quadrants remain static. The MON-A monitor must
NOT be in full-screen display mode when starting
sequencing. The full-screen or zoomed displays on the quad
monitor cannot be sequenced.
To start sequencing of an individual quadrant which is not
already sequencing, first press any arrow button once to
initiate the active quadrant mode, then use the arrow
buttons to select the quadrant and press SEQ. This will
immediately start sequencing in the active quadrant, while
the status of the other quadrants will not be affected.
If sequencing is required in other individual quadrants, use
the arrow buttons to select a new active quadrant and
press SEQ. The active quadrant automatically times out in 5
seconds after there is no button activity, so when all
quadrants have been programmed there is no further action
required by the operator to exit the active quadrant mode.
Alternatively, pressing QUAD at any time will end the active
quadrant mode.
Quadrants will sequence between the two input cameras
related to the quadrant, namely 1 and 5, 2 and 6, 3 and 7,
and 4 and 8 respectively.
To stop sequencing of one individual quadrant, use the
arrow buttons to select the appropriate quadrant and press
SEQ.
To stop sequencing of all quadrants, press QUAD.This stops
sequencing and automatically selects the camera 1 thru 4
quad display.
Note that on the TC8278 Series, by starting and stopping
sequencing in individual quadrants, the user can get page
displays different to the standard pages of cameras 1 - 4, and
5 - 8. For example, camera 6 can be displayed along with
cameras 1, 3 and 4. To return to the standard quad pages of
1 - 4 and 5 - 8, press QUAD which selects the first quad
page of cameras 1 - 4, and then select sequencing or the
alternate page as desired.
If the MON-A monitor is in full-screen display mode, the
SEQ button will be ignored. Full screen displays on the
MON-A monitor cannot be sequenced.
5.2.9 FREEZE Button
Freezes or unfreezes all quadrants of the MON-A monitor
display.
Only images displayed on the MON-A monitor output can
be frozen. The FREEZE button has no effect on MON-B
monitor displays.
The FREEZE button is used both to freeze and to unfreeze
displays.
The operator can freeze any image on the MON-A monitor.
Full-screen displays, one quadrant of a quad display, or all
quadrants of a quad display can be frozen via a front panel
FREEZE button for further investigation of the image.
Note: FREEZE always stops any sequencing in the frozen
quadrant(s) of the image. Selecting alternative modes by
pressing SEQ, QUAD or ZOOM also unfreezes the display.
Freezing All Quadrants
When no active quadrant is selected on the MON-A
monitor output, FREEZE will cause all 4 quadrants of the
present quad display to be frozen. If the FREEZE button is
pressed again, it will unfreeze all quadrants.
Freezing Individual Quadrants
If an active quadrant has been selected (refer to Arrow
Buttons), the FREEZE button will cause only the active
quadrant to be frozen or unfrozen.
Freezing a Full-screen or Zoomed Image
If a full-screen or zoomed image has been selected on the
MON-A monitor output, FREEZE will cause the MON-A
monitor display to be frozen. If the FREEZE button is
pressed again, it will unfreeze the display.
Unfreezing a Display
Besides using the FREEZE button as indicated above, any
frozen display will be automatically unfrozen when a mode
change is requested by using the QUAD, SEQ,VCR or
ZOOM buttons.
