EQUIPMENT REQUIREMENTS
The QSP-421SS is designed to be compatible with all EIA and CCIR compatible equipment. Two versions
of the product are available to make best use of these two standards. The EIA version (indicated by serial
numbers 23....) will only be compatible with EIA installations. The CCIR version (indicated by serial
numbers 24.... ) will be compatible with both EIA and CCIR installations. For installations requiring a
mixture of CCIR and EIA cameras, it is recommended that the CCIR version QSP-421SS be used, with a
CCIR camera on input #1. The remaining camera inputs can take either EIA or CCIR cameras.

The QSP-421SS will accept 2:1 interlace cameras in either a “line-locked” or “free running” (internal
reference) modes. ATV does not recommend "Random Interlace" cameras.
To connect and use the new QSP-421SS in the same manner as the previous versions of the QSP-
421SS, please refer to the “Standard Configuration” diagram on page 2. This configuration provides
access to all of the new QSP-421SS features with the exception of the VCR playback “zoom” feature.
To use the VCR playback “zoom” feature, refer to the “Zoom Configuration” diagram on page 2. This
configuration provides access to all the new features of the QSP-421SS as well as the VCR playback
“zoom” feature. The VCR playback “zoom” feature enlarges a single quadrant of the display during
playback to full screen. This allows the viewing of a single camera from a quad display recording.
Because the VCR playback “zoom” is an enlargement of a smaller picture, the resulting full screen display
will be of lower resolution. It is reasonable to expect some loss of detail and picture jitter in VCR playback
“zoom” mode, especially in slow motion and still frame playback (refer to Field/Frame Mode Selection on
page 6).

FRONT PANEL OPERATION
Using the figure above as your guide, you can select different display modes by pressing one or more of
the following four buttons.
QUAD: Returns the unit to QUAD MODE directly from any other mode.
MODE : Switches from QUAD MODE, and with each press, cycles
through FULL SCREEN MANUAL, PICTURE IN PICTURE, FULL SCREEN
SEQUENCING, PIP BACKGROUND SEQUENCING, PIP INSERT
SEQUENCING, and back to FULL SCREEN MANUAL.
CAMERA/ZOOM: Within each mode except QUAD, FULL SCREEN SEQUENCING, OR VCR, this
button will allow you to select particular cameras (e.g. 1, 2, 3 & 4). When in PIP
mode, pressing and holding this button for at least 1 second will cause the PIP to
rotate to the next quadrant. The order is lower right, lower left, upper left, and
upper right.
VCR: Pressing this button will switch the video source input back and forth from the
cameras to the VCR which will be indicated by the right most indicator (an
amber led). If the indicator is on, the video input is from the VCR. When in the
VCR mode, pressing the CAMERA/ZOOM button will cause the display to come
from the upper left quadrant of the VCR playback display. Successive pushes of
the CAMERA/ZOOM button will cause the displayed quadrant to change to the
next quadrant. The order is upper left, upper right, lower left and lower right.
Another press of the CAMERA/ZOOM button will return the display to a full
screen VCR playback display.

BACK PANEL CONNECTIONS
There are eleven BNC connectors on the back of the QSP-421SS. Four of these BNC connectors are for
the camera inputs and corresponding looping outputs (8 total). One BNC connector is provided for a VCR
input, another for an output to the VCR, and another for the output to a monitor. Cameras 1 through 4
connectors are labeled with their display position in the quad mode display.
Each camera input of the QSP-421SS supports loop-though with a second BNC connector. The loop-
through 75 ohm termination resistor within the QSP-421SS is enabled as a factory default (see page 6 for
instructions).

The factory default alarm contact option is
“normally open” (see following section on
alarm contact options). A contact closure on
any alarm input (which “grounds” that input by
connecting it to the alarm connector ground
pin) puts the QSP-421SS in an “alarm” state.
In this state, the unit will switch to a full
screen view of the camera associated with
that alarm input. If more than one alarm input
is activated, then the QSP-421SS will
sequence between each “alarmed” camera at
the normal dwell rate. The alarm output will
be activated when there is an alarm input. An
alarm condition exists until the alarm input is
deactivated.
The alarm output is limited to 30 mA of current
and an external relay should be used to drive
any high powered or high voltage device. An
external resistor pull-up is required for some
systems when the alarm out is deactivated.
The pull up resistor (10K ohm typically) may
be connected to the +5 Volt pin or some other
higher voltage not to exceed +25 Volts
(sometimes used in +12 Volt systems). The
“off” or “open circuit” voltage on the alarm
output should not exceed +25 Volts to avoid
damaging the alarm output.

Current
The +5 Volt and ground pins are connected through an internal 100 ohm resistor for short circuit
protection. This limits the current to about 50 mA if the +5 Volt supply shorted to ground. If the +5 Volt
supply is used with the alarm output to drive an external load (as shown above) the internal resistor and
the load should produce less than 30 mA current to prevent damaging the alarm output.
The “Freeze” input pin will halt all picture input processing which will effectively “freeze” the present image
on the quad output. Activating this pin is similar to an alarm input which merely requires “grounding” to be
active.

QSP-421SS: Instructions for basic operation and installation Page 6
INPUT TERMINATION
The “C” jumpers affect the camera input termination resistor. When
the jumper is installed a 75 Ohm termination is connected to the
respective cameras. Additionally the “V” jumper serves the same
purpose on the VCR input. For proper operation a termination resistor
of 75 ohms should be on the last piece of video equipment which is
connected to a given camera. For a simple system where cameras
are brought directly into the QSP-421SS, the termination resistors are
always enabled (factory default). When connecting a camera to more
than one piece of equipment, or if “loop through” is used, individual
terminating resistor jumpers should be removed and the termination
should be made at the monitor(s).
ALARM CONTACTS
The “A” jumper affects whether the alarm inputs are active when the
contacts are closed (jumper installed - factory default) or open (jumper not installed). In either case the
assumption is that the alarm contacts connect together the ground pin and the alarm input pin associated
with a particular camera. For “normally open” type contacts, the “A” jumper should be installed. For
“normally closed” type contacts, the “A” jumper should not be installed. The QSP-421SS assumes that all
the alarm inputs are of the same type. Selecting an incompatible combination of contact type and option
setting will result in the QSP-421SS being in a continuous “alarm” condition which is indicated by the unit
to seemingly be stuck in full frame sequencing mode, and generating a continuous alarm output state.
Please note that if less than four alarm inputs are used and “A” jumper is not installed, the remaining
alarm inputs must be grounded (Tied to pin 10).
DWELL OPTIONS
The QSP-421SS dwell time is set by SW9 and affects the
amount of time between camera changes. The dwell
setting is set to a factory default of 4 seconds but is
adjustable in 4 sec steps from 4 to 16 seconds.
The dwell time affects:
1. Full frame sequencing dwell time.
2. PIP background sequencing dwell time.
3. PIP insert sequencing dwell time.
4. Alarm full frame sequencing dwell time
(when more than one simultaneous alarm input).
FIELD/FRAME MODE SELECTION
Switch positions #1 and #2 on SW9 control how video field information is handled. We have preset them to
defaults that should work with most systems, but there is a very large variation in the behavior of VCRs and you
may have to experiment with the settings that work best for your installation.

QSP-421SS: Instructions for basic operation and installation Page 7
Some VCRs (in certain modes) and cameras will fail to generate correct field information that can be decoded by
the QSP-421SS. A camera or VCR of this type may cause the Quad picture to jump up and down by one line or
generate intermittent picture refreshing. In VCR recording and playback, the field decoding problem can cause line
reversals and “motion artifacts” when playing back a recording of a 525 line frame (625 for CCIR).
Most time-lapse VCRs on the market are “field recorders” and if frame recording is desired (for better line
resolution), the recommendation is to use “real-time” 24 hour recorders where the tape is always in motion.
Motion artifacts can be eliminated by the use of shuttered cameras with a shutter speed set to 30 frames per
second (25 frames per second for CCIR). Non-real-time VCRs should use field mode recording which is the
factory default setting.
FIELD MODE (SW9:Position #2 = OFF)
This switch option sets the unit to display on its output only one field of video which is repeated twice per frame.
This same field is used during playback for both full screen and quadrant zoom. In a few cases when the VCR is in
playback but “paused”, the picture will jump (vibrate) by one line. Setting SW9:Position #1 to ON usually
compensates for this. For most other cases SW9:Position #1 should be OFF.
FRAME MODE (SW9:POSITION #2 = ON)
In frame mode each independent field which makes up a frame will get displayed for monitoring or recording. In a
system without a VCR, frame is the recommended mode of operation since it has twice the line resolution as field
mode. When used with a VCR, field mode is recommended. During VCR playback, most VCR’s will generate
intermittent field information in non-linear time lapse mode. Some VCRs tend to play back more odd fields than
even and other VCRs tend to playback more even fields than odd. SW9: position 1 should be set to whatever
position works best for that particular VCR.
