5.1.1  
Initiating Menu Programming  
4.6 Alarm Inputs and Output  
(Accessory Output)  
To start a menu programming session, press the MENU  
button.  
4.6.1  
TC8277 Series andTC8278 Series  
The operator will be prompted to enter a password,  
consisting of a three button sequence of the front panel  
buttons. The password can be programmed by the  
operator.  
The 609 mm (24 in) cable, with 15 pin connectors provided  
with theVidQuad® units, are for use with the mating alarm  
input, output and accessory connectors. These cables can  
be cut to desired length, and the end insulation stripped off  
for connecting external devices.  
The factory setting for the password is SELECT, SELECT,  
SELECT.  
Note that the SELECT button is not normally a valid  
password button and cannot be used in a new password  
when it is set by the operator. The only time that this  
button is used in the password is as a factory default on  
new units. Buttons which are used in normal MENU  
operation - the MENU, SELECT and ARROW buttons - are  
not valid as password buttons. All others are valid.  
4.7 Alarm Inputs  
4.7.1  
TC8277 Series andTC8278 Series  
The alarm inputs are defaulted to be normally open. These  
can be individually changed to normally closed via the Alarm  
menu.  
CAUTION: Do not apply external voltages to  
the alarm inputs.  
Once the correct password has been entered, a main menu  
will be displayed, showing each of the major sections that  
can be programmed by the operator. In general, the on-  
screen prompts will be all that are needed to guide the  
operator through the steps to select and program the  
options.  
Belden 8760 twisted shielded cable (or  
equivalent) should be used for wiring to the  
alarm connector and the total length of  
unshielded cable should not exceed 10 cm  
(3.9 in) on each connector port to maintain  
compliance with Directive 89/336/EEC.  
Each screen prompts the operator on the correct buttons  
to use for various options and functions.  
Use only isolated closures or open collector logic.  
Precautions should be taken, particularly on long runs, to  
prevent pickup of spurious signals from associated wiring  
which may give false inputs or damage the unit. Refer to  
the Alarm/Accessory Connector - Pin-Out under  
ILLUSTRATIONS.  
5.1.2  
Selecting Menu Items  
Move up and down through the menu by using the up and  
down arrow buttons, and choose a menu item by pressing  
the SELECT button. This will bring up a new screen which  
allows the operator to select options or enter data related  
to the menu item which was chosen.  
4.8 Alarm Output  
Option Selection  
In menu screens where items in a list must be turned ON  
or OFF, use the left or right arrow buttons to toggle the  
status of the current entry, then press the down arrow  
button to move on to the next entry. The up or down  
arrow buttons are used to skip over or select entries on  
the screen. When there are more entries than can be  
displayed on one screen, the screen will scroll automatically  
when the down arrow is pressed on the bottom entry. The  
up arrow can be used to scroll up to preceding entries if  
needed. Press SELECT when done to exit the screen.  
4.8.1  
TC8277 Series andTC8278 Series  
The alarm output is a relay which is configured to be  
normally open. The relay contacts can handle up to 1  
ampere at 40 volts AC/DC and will close upon alarm input  
to the unit. The video loss output is a logic low. Refer to  
the Alarm/Accessory Connector - Pin-Out under  
ILLUSTRATIONS.  
5 OPERATION  
5.1.3  
Data Entry  
5.1 Menu Operation  
Some menu screens provide a means for the operator to  
enter numeric or alpha-numeric data. In these menus, a  
current cursor indication is provided by means of the "Up-  
Arrow" character below the position at which data is to be  
entered. The up and down arrow buttons will then cycle  
through the displayable character set, while the left and  
right arrow buttons are used to move to subsequent or  
preceding character locations. Once all characters have  
been set up correctly, the SELECT button will confirm the  
data entry and call up the subsequent camera, if applicable. If  
there is no subsequent camera, then SELECT will return the  
operator to the main menu.  
In setup mode, the user has access to on-screen menus for  
programming system settings and installation data such as:  
Titles  
Alarm Operation  
Sequencing Operation  
Time/Date Setup  
Password Setup  
Remote Configurations  
For an overview of operator programmable menu options,  
refer to Menus Flow Chart under ILLUSTRATIONS.  
Menu operation is password protected to prevent  
unauthorized access, and can be set by the user.  
5.1.4  
Terminating Menu Programming  
Menu programming can be terminated at any point by  
pressing the MENU button again.  
Although the menus include "EXIT" selections, the MENU  
button can be pressed at any time while in the menus to  
immediately exit the setup mode and return to normal  
operation. Any programming made up to the "menu" exit  
time will be saved.  
All changes are automatically saved by the system as they  
are made. Settings are retained even on loss of power.

5.2.5  
ZOOM Button  
5.2 Monitor Operation  
Operates only on the MON-A monitor. Used to switch  
from quad displays to full-screen displays on the Quad  
monitor, and also to zoom the full-screen displays.  
5.2.1  
Monitor Display Outputs  
The front panel buttons can be used to operate either on  
the MON-A monitor display, or on the MON-B monitor  
display. The MON-A monitor displays a digitized image and  
so Zoom and Freeze operations can be performed on the  
MON-A monitor. The MON-B monitor displays analog full-  
screen images only, and so quad compression, Zoom and  
Freeze cannot be performed on the MON-B monitor  
output.  
Full-screen Display Selection  
If an active quadrant is first selected, displays the  
corresponding camera full-screen.  
If no active quadrant is selected, it operates on the last  
active quadrant that was selected for full-screen display.  
Once in full-screen mode, the arrow buttons will switch to  
alternate full-screen views.  
5.2.2  
Mon-A Monitor Display  
The first monitor output, designated as the MON-A  
monitor, is used mainly for quad displays. It will  
simultaneously display four camera images which have been  
digitally compressed to one quarter of normal size, along  
with camera ID, titles and status information.  
5.2.6  
Zoom Mode  
Zooms a full-screen camera display using a digital 2X Zoom.  
Zooms theVCR display on the MON-A monitor.  
If a display is already zoomed, then pressing the ZOOM  
button toggles the display back to full-screen.  
The MON-A monitor can also be used for digital full-screen  
camera display, manually or via alarm inputs, so that if an  
installation is not suited to the use of two display monitors,  
the operator still can have full-screen call-up capability.  
The indicator 'ZOOM' is displayed if an image has been  
zoomed.  
Once a full-screen display has been zoomed, the arrow  
buttons can be used to continuously pan and tilt around the  
zoomed display. Note that frozen full-screen images cannot  
be zoomed. However, zoomed displays are fully interlaced  
and can be frozen at any time.  
5.2.3  
QUAD Button  
Selects the quad display on the MON-A monitor output.  
On the TC8278 Series, subsequent pressing the QUAD  
button will toggle between alternate quad pages (cameras 1  
thru 4, and then cameras 5 thru 8).  
5.2.7  
VCR Button  
Selects for display on MON-A and MON-B the video  
source that is connected to the "VCR" BNC on the rear  
panel.  
5.2.4  
ARROW Buttons  
Used to select an 'active' quadrant on the MON-A monitor.  
Each arrow button is mapped to a quadrant on the screen,  
and will alternately select the two cameras associated with  
that quadrant.  
If the source is playback from a time-lapseVCR,  
playback speed must be in the 2 hour mode for  
proper operation.  
In the MON-A monitor display, the operator can operate  
on either the full screen display, or only on individual  
quadrants of the display. To operate on individual quadrants  
in the quad display, an active quadrant must first be selected  
by the operator from the four displayed images.  
For best performance, when using the "VCR" input  
selection, it is recommended that both record and  
playback of the quad video be in the 2 hour mode.  
InitiatingVCR Playback Mode  
VCR playback is initiated by pressing theVCR button on the  
front panel, which will route theVCR input to both the  
MON-A and the MON-B monitors.  
Active Quadrant Selection  
If any of the arrow buttons are pressed while the MON-A  
monitor is in quad display mode, an active quadrant is  
indicated in the corresponding quadrant of the quad display.  
The active quadrant is indicated by flashing the camera  
number and title of the camera in that quadrant. Adjacent  
quadrants can be selected as the current active quadrant by  
pressing the appropriate arrow buttons. If no further  
buttons are pressed, the active quadrant mode will  
automatically time out. While the active quadrant indication  
is active, buttons like SEQ, FREEZE and ZOOM will affect  
only the active quadrant, as opposed to the whole page of  
the quad display.  
During this mode the text "VCR" is displayed on the  
monitors. The MON-A monitor can be used to display live  
playback images, frozen images or zoomed images of one  
quadrant of the playback.  
Freeze DuringVCR Playback  
To freeze or unfreeze the display at any time duringVCR  
playback, press FREEZE. The text "FRZ" will indicate that  
the image is frozen. Zoomed images can also be frozen.  
The use of theVCR's PAUSE button can also freeze the  
image being displayed. Using the pause feature of theVCR  
will stop video update as the image is frozen, allowing for  
greater control of the playback.  
Active Quadrant De-selection  
The active quadrant display indication stays visible for  
approximately 5 seconds after the last keystroke, after  
which it is automatically reset and the unit reverts to quad  
mode.  
Pressing the QUAD button at any time will exit the active  
quadrant mode.

Zoom DuringVCR Playback  
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 zoom a quadrant in the recordedVCR 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 normalVCR  
playback.  
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.  
The MON-B monitor will continue to display the fullVCR  
signal continuously. The dualVCR input displays give the  
user maximum flexibility to examineVCR playback.  
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.  
To exitVCR mode: PressVCR.  
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.  
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.  
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.  
5.2.9  
FREEZE Button  
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.  
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.  
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 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.  
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.  
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  
If sequencing is in progress on either monitor, it will be  
indicated on-screen on the corresponding monitor(s) by the  
indicator "SEQ".  
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.  
Individual Quadrant Sequencing  
(TC8278 Series Only)  
Freezing Individual Quadrants  
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.  
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.  
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.  
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.  
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.

5.2.10 MON-B Monitor Display  
5.3 Alarm Input Operation  
The secondary monitor output, designated as the MON-B  
monitor, is used for selecting analog full-screen displays of  
any one of the eight camera inputs, or to display a  
sequenced list of full-screen displays. The MON-B monitor  
output is analog and so digital functions such as quad  
compression, zoom and freeze are not available on the  
MON-B monitor.  
The product is equipped with 4 alarm inputs (TC8277  
Series) or 8 alarm inputs (TC8278 Series), each associated  
with its corresponding video input. System action during an  
active alarm includes on-screen indication of the camera in  
alarm (ALM), a front panel LED indicator, an alarm output  
relay and the MON-B monitor switching to the camera in  
alarm. If multiple cameras are in alarm, the MON-B  
monitor automatically sequences between the cameras in  
alarm at a preset dwell rate of 1 second.  
The operator can either select full-screen displays of any  
camera to the MON-B monitor, or the displays can be  
selected automatically to the MON-B monitor screen as a  
result of an external alarm input. Full-screen camera views  
can be sequenced on the MON-B monitor. The MON-B  
monitor can also display the same images that are being  
displayed at any one time on the MON-A monitor.  
The alarm inputs are configured as zero potential relay  
contacts, individually programmable via the menu to be  
normally open (NO) or normally closed (NC). Refer to the  
setup MENU to select the input configuration as NO or  
NC. Any alarm inputs can be enabled or disabled via the  
setup MENU.  
The MON-B monitor sequence list can include any of the  
input cameras, as well as the quad images selected for the  
quad display monitor. The MON-B sequence list can accept  
up to sixteen entries and can include any input several times  
and in random sequence.  
Alarms may be cancelled (acknowledged) via a contact to  
ground on a rear panel input, or by pressing the SELECT  
button.  
5.3.1  
Alarm Input Handling  
The sequence dwell times for the MON-A and MON-B  
monitors can be set separately by the operator via the  
menus.  
There are three ways of handling alarms, which may be  
selected by the operator in the setup MENU.  
5.2.11 MON-B Button  
Used to toggle the front panel control from MON-A  
control to MON B control and visa versa.  
5.3.2  
Latched Alarms  
Alarms are latched as they become active. An alarm is  
cleared when the operator acknowledges it. There is no  
time out period.  
Fixed full-screen displays can be selected on the MON-B  
monitor by pressing MON-B followed by the appropriate  
arrow button. Each arrow button is mapped to a quadrant  
on the screen, and will alternately select the two cameras  
associated with that quadrant.  
Note: When the operator acknowledges (cancels) the  
alarm, it will be cleared whether the alarm input is still  
active or not.  
Alarms that have been acknowledged by the operator will  
not be reactivated until the alarm input has ceased and then  
restarts.  
The MON-B monitor output is analog. Digital functions  
such as zoom and freeze have no effect on the MON-B  
monitor output.A flashing "MON-B" indication on the  
monitors advises the user that the front panel is controlling  
the MON-B monitor.  
5.3.3  
Timed-out (Captured) Alarms  
Timed-out alarms are latched for a minimum time out  
period from the start of the alarm becoming active. The  
time out period is menu programmable. After expiration of  
the time out period, the alarm is automatically cleared.  
5.2.12 ARROW Buttons (MON-B)  
Used to select a camera for display on the MON-B monitor,  
provided that the MON-B button is pressed before the  
arrow button.  
Alarm inputs that are still active after the time out, become  
manual type alarms. Alarms that cease and restart before  
the time out is complete, will restart the time out period.  
Timed out alarms can be cleared by the operator before  
they time out. Alarms that are cleared before their inputs  
have ceased, will not be reactivated until the alarm input  
ceases and restarts.  
Each arrow button is mapped to a quadrant on the screen,  
and will alternately select the two cameras associated with  
that quadrant.  
5.2.13 SEQ Button (MON-B)  
Sequencing on the MON-B monitor output may be toggled  
on and off by using the SEQ button.  
5.3.4  
Manual Alarms (No Capture)  
Alarms are active only while the alarm input is active. As  
soon as the alarm input ceases, the alarm is cleared.  
To start sequencing while in the MON-B mode, press the  
SEQ key. Sequencing will commence at the MON-B  
sequence dwell time.  
5.3.5  
Clearing Alarms  
The MON-B monitor dwell time is programmable between  
1 and 99 seconds.  
Alarms are cleared by pressing SELECT/ALARM CLR, or by  
pulling a rear panel contact (pin 4) to ground. Refer to the  
rear panel drawing for the location of the contact.  
The MON-B sequence list can contain up to 16 entries  
which are operator programmable via the menu. The  
sequence list can include any camera or the MON-A display  
in the list several times, and in random order.  
To start/stop sequencing on the MON-B output, select  
MON-B followed by SEQ.

5.3.6  
Video Loss Action  
page. When that camera quadrant is next sequenced it will  
display a blank image with the video loss warning message.  
Sequence lists are not automatically changed as a result of  
video loss. Cameras with video loss can still be selected for  
display on the MON-B monitor screen, which will be blanked  
while that video loss input is selected, but will still display  
the camera title, time/date and other status text.  
Upon video loss to any input, the corresponding camera  
image on the MON-A display is automatically frozen, and a  
video loss warning message, "VDL" is displayed on the  
corresponding quadrant as well as on the associated MON-B  
monitor display. If the MON-A monitor is sequencing at the  
time that the video loss occurs, the frozen image will be  
discarded when the monitor switches to a new sequence
