The term multiplexer was given to an electronic device that time-multiplexes video pictures from numerous cameras onto one VCR. This means
that one field or frame from one camera was switched to the VCR, then immediately following that picture was another field or frame from another camera and so on from each camera, then it started over again. This technique
maintains full resolution as does normal video switchers but reduces the time
between recorded images so the 2-3 second dead time between normal camera switching was reduce to 17ms (milliseconds) times the number of cameras. The multiplexer electronically marks each picture with a camera number so it can be identified upon playback.
When the recorded tape is played back through the multiplex the multiplexer electronically identifies the desired picture to be viewed. When the
picture is identified the multiplexer updates the viewable image on the monitor so you only see the requested image or images if in the quad mode.
There exits three types of multiplexers in Black & White or Color; Simplex, Duplex or Full Duplex. The Simplex models are for unattended operation since they can only view switched images when the multiplexer is in the
recording mode. Duplex models allow simultaneously recording on the VCR,
while the operator can view the total number of cameras viewed at once on
the multi-screen display. Full Duplex allows the playback of a second VCR
while viewing the multi-screen display while the first VCR remains recording.
The AVE QM line of multiplexers are Black & White Simplex. They do
however have features above the standard Simplex design. The high resolution give the QM line the most advanced performance & features of any Black
& White simplex multiplexeres. The name QM stands for Quad or Multiplexer since the QM series has the ability to be a real time 60 Hz quad or
sequencing Duoquad (QM8) or a high performance simplex multiplexer. W ith
2 monitor outputs the user can be viewing the call monitor with live images
while watching the playback on an additional monitor.
For additional information on multiplexers visit the AVE website at
www.americanvideoequipment.com and click “Education”. A more detailed
white paper on multiplexer technology is available here.

4. FRONT PANEL
There are 16 push buttons on the QM8, and 12 push buttons in QM4 as shown in Figure 1.
They are described as follows:
MENU:
Press this button to bring out the menu-driven setup feature. Press it again while in
the programming mode will exit the menu immediately .
ZOOM/SET :
In record or play mode, press this button to zoom in the picture. It is a 2x zoom with 9
centering positions. In programming mode, use to set or change the value or enter
into a sub menu.
FULL/<:
In record mode, press to get into multiplex recording; In the play mode, press to switch
to full screen display; in ZOOM mode, press to move the zoomed picture to the left
position; in programming mode, press to move cursor left whenever necessary .
QUAD/>:
In the record mode, press the switch to view the real time quad output; for the QM8
press again to view the alternate quad; In the playback mode, press to switch the
display to Quad; In the QM8 press to switch to the alternate quad;in ZOOM mode,
press to move the zoomed picture to the right position; in programming mode, press
to move the cursor right whenever necessary .
SEQ/UP:
In the record mode, press to switch the cameras sequentially . If the MON LED is ON,
the Call Monitor output will be switched sequentially . If MON LED is off then the record
output to the VCR will be a sequencing image rather than the multiplexed record signal. In ZOOM mode, press to move the zoomed picture up; in programming mode,
press to move cursor up or change the value if the cursor is flashing..
MON/DOWN:
In the record or play mode, press to switch the front panel push buttons to control the
call monitor output. When selected the MON LED will be ON, SEQ, CAM1-8 are
used to switch the call monitor output; in ZOOM mode, press to move the zoomed
picture down; in programming mode, press to move cursor down or change the
value if the cursor is flashing.
PLA Y :
Puts the QM in in Quad play mode, also switches the call MON OUT to playback
mode.
RECORD:
Puts the QM in the record mode, also switches the call MON OUT to sequence
through all cameras live.
CAM1-CAM8:
If the MON LED is OFF , switches the VCR OUT to selected camera input. If the
MON LED is ON, switches the call MON output to selected camera input.
Warning: The QM series has the ability to change the multiplex recording output to
either a single camera or sequencing through all cameras with a digitized image.
When the MON LED is off you are programming this record output.

Combination Buttons
Playback:
While in the playback mode both monitors will show the playback image
the same. If you want to view the live multiplexed output of the VCR or to program the
VCR via its on-screen programming, press the PLA Y and MON buttons simultaneously.
Pressing the Play button again will return to the normal play mode.

5. BACK PANEL
POWER:
The QM takes 12VDC @ 400 ma via a DC adapter that plugs in the back of the
QM.
VCR OUT:
The VCR OUT should be connected to the input of the VCR.
VCR:
VCR is the playback / record monitor output. In the record mode it displays the
multiplexed picture output to the VCR, in the playback mode it displays the quad or
full screen playback or the live multiplexed output of the VCR.
VCR IN:
VCR IN should be connected to the output of the VCR and is programmable terminated or unterminated.
MON:
MON can be connected to the input of the call monitor.
VIDEO IN:
Cameras can be connected to QM VIDEO IN connectors and are programmable
terminated or unterminated as a global setting.
LOOP OUT:
Video output of the corresponding camera. Must be programmed for Hi-Z or
unterminated when this option is used to guarantee quality recorded video.
REMOTE CONTROL:
The DB-25 female connector is used for RS-232 communication, alarm input/output and trigger pulse input/output connections. The pin out of Remote Control is
shown in figure 4.

6. Connections
1. Before connecting make sure all the equipment is powered down.
2. Connect the QM with Cameras, VCRs, Monitors and power as shown in
Figure 3.
3. Power up the system. The QM will go into the multiplexer record mode
by default, the call monitor will be sequencing through the live cameras,
and the VCR playback monitor will have the multiplexed image that goes
to the VCR.
