Programmable quad Q4M (Q8M) is a digital
apparatus, which enables displaying of 4
cameras (two pages of four cameras) on one
output (QUAD).
It also enables switching of input video sig-
nals of the cameras and a quad screen. The
switching can be provided manually or with
the help of programmed sequence for the
main output (MAIN). It is possible to set up
cameras, which are at the right time available
for automatic switching. This makes possible
to disconnect temporarily uninteresting or
disconnected cameras. An operator attention
can be focused only on important camera
images.
The unit contains 4 (8) alarm inputs. The
quad itself remembers the last setting of ac-
tive cameras, a programmed sequence and
the time of switching an alarm output, even
after the unit had been switched off.

MONITOR OUTPUTS
Outputs QUAD and MAIN are individual video
outputs for connecting monitor or VCR. For
the correct function of the connected appa-
ratus the signal cables must have the imped-
ance load of 75.
ALARM INPUTS
One alarm input is suitable for one video in-
put. Alarm loops are connected between
alarm input and common conductor - ground
(GND).
ALARM OUTPUT
Quad has its own potentialless alarm output
made of the normally open contacts of the
relay.
ALARM CONNECTOR
Alarm connector is used for connecting alarm
inputs and outputs. The connection of 25
outlet connector CANNON is illustrated on
the pictures 5 and 6 (page 4).
POWER SUPPLY INPUT
Quads Q4M (Q8M) are supplied from a uni-
flow supply of 12 V. Energy input is 4 W
maximum. For connecting supply voltage is
used a concentric connector 5,5 x 2,1 mm.
The positive supply pole is on the inside con-
tact of the concentric connector, the con-
nector jacket is the negative pole.
BASIC MODE
After turning on, the quad cyclically switches
among active cameras according to the se-
quence, which has been set up. The auto-
matic switching is signaled by the SEQ light-
emitting diode (LED), the camera displayed
on the main video output (MAIN) is signaled
by the diode of the buttons 1 –4 or QUAD
(1 –8, QUAD1 AND QUAD2 for Q8M).
MANUAL SWITCHING
Press the corresponding button to display
cameras 1 –8 or quad screens QUAD,
QUAD1 and QUAD2.
AUTOMATIC SWITCHING
The automatic switching starts by pressing
the button SEQ.
If the quad does not start to switch automati-
cally, check the camera settings in the menu
SEQUENCE and TIME (page 6).
CAMERA FREEZE IN QUAD SCREEN
Be sure, there is a quad picture displayed on
the output MAIN.
Press and keep the button 1 –8, the camera
screen will stop (freeze) or run-up if it was
stopped. When the picture is frozen, the
camera LED is shining together with the quad
picture LED QUAD, QUAD1 and QUAD2.
If the LED above the buttons 1 –4 (1 - 8 by
Q8M) is shining, the video signal of corre-
sponding cameras is missing.

Quads Q4M and Q8M contain a graphical
menu, which enables the setting of the fol-
lowing functions.
oCameras activation for automatic
switching
oSwitching period set up
oAlarm functions set up
oInterlace correction
MENU - MAIN MENU
To display the main menu on the screen
press the button MENU. Choose the required
function by pressing the buttons 1, 2 and 3.
SEQUENCE –CAMERAS ACTIVATION
By pressing the button 1 is the menu for
cameras activation and deactivation for au-
tomatic switching displayed.
By pressing the buttons of individual cameras
activate or deactivate automatic switching
cameras. Activated cameras are marked by
sign .
If the cameras are set up, the quad will
switch automatically among cameras 1, 2, 3,
4, Q1, 1, 2, …
In case you make a mistake by sequence
programming (none or only one camera is
active) and you start the switching sequence
by pressing the button SEQ on the front pan-
el, notice „INCORRECT SEQUENCE“ will
appear. In that case is necessary to set up
cameras in the SEQUENCE menu properly.
TIME –SWITCHING PERIOD
By using the buttons 1 and 3 (1 and 5 by
Q8M) is possible to prolong or slow down the
switching time among individual cameras and
quad pictures, at intervals 1 –99 sec.
ALARM –ALARM SET UP
The quad detects an alarm, when the con-
nection is provided between the alarm input
1 –8 on the CANNON connector of the back
panel and the common conductor –ground
(GND). By the help of the buttons 1 and 3 (1
and 5 Q4M) set up quad reaction for an
alarm. The reaction can be:
OFF - alarm is off - quad does not
respond to the alarm.
FOLLOW - quad signalizes an alarm as
long as any alarm input is ac-
tive.
2-255 S -quad signalizes an alarm for
the set up time since the alarm
event had occurred.
If an alarm occurs, the quad makes the fol-
lowing steps:
1. it switches the alarm output (relay) –sig-
naled acoustically (beep).
2. it switches a camera corresponding to the
alarm input for the set up time.
The alarm stops after the end of the set up
time interval, after pressing any button or
after the end of the alarm event in the mode
FOLLOW
.

INTERLACE CORRECTION ON/OFF
By pressing the button 4 switch ON/OFF the
interlace correction. Off interlace correction
of the life screen can cause a gliding effect,
which is evoked by projection of different
half-fields of the same camera. If you choose
the item (INT.ON), always the same half-field
will be shown. With the stability screen im-
provement will be the projection slower.

YOUR TROUBLE
THE CAUSE AND ITS SOLUTION
After connecting the sup-
ply voltage device does
not work.
The power supply is not connected.
Check the supply connector and the polarity of power supply,
switch on the power breaker.

Check if the adapter power output and voltage agree with the quad
requirements.
After connecting the sup-
ply voltage the LEDs are
on, but the device does
not work.

the quad screen.
The supply adapter is not dimensioned sufficiently.
Check if the adapter power output and voltage agree with the quad
requirements.
