NTRODUCTION
Thank you for purchasing Advanced Technology Video’s QSP-860MPX eight camera Duplex Multiplexer.
This instruction manual describes the powerful features of this product for basic and advanced operation.
It also covers the installation steps that will allow quick and easy integration into your security system.
Throughout this manual we will refer to a 3x3 display format for simultaneous display of all eight cameras.
The QSP-860MPX utilizes eight of the nine possible display areas of the 3x3 display format for display of
the eight cameras. The ninth area (middle space) is used to display time and date information during the
live camera display mode, or the message “VCR Playback” during playback mode.
The following section provides an overview of the operational features of the QSP-860MPX. If you are
familiar with the QSP-860MPX, you should proceed to the “Getting Started” section on the following page
for step by step installation instructions.

Live Camera Displays
The QSP-860MPX will initially be in the live camera display mode whenever power is applied to the unit.
Live cameras can be displayed in 3x3, quad (dual page), PIP, dual PIP, split screen, squish screen, or full
frame formats. In addition, any display may be frozen using a front panel button, the IR remote control, or
an external signal input. In any of these display modes, the unit can be programmed to sequence one or
more cameras with a programmable dwell time.
Multiplexer Recording/Playback
The QSP-860MPX records each camera individually onto a single video frame of the VCR tape at a rate
compatible with the VCR recording speed (record hours mode). Proper VCR playback operation requires
that the QSP-860MPX be set up to multiplex at the rate which is compatible with your VCR recording
speed (see page 8). During multiplexing, a single frame from each camera is alternately output to the
VCR with the factory default set so that each live camera is given an equal number of frames on the tape.
Dead or unconnected camera inputs will not be recorded. In order to optimize recording for your security
situation, the frequency with which individual camera inputs are sampled for multiplexing may be optionally
configured using the Customplexing
camera priority function. The Camera priority set up menu allows
you to set four levels of priority (giving more frames to high priority and less frames to low priority). While
multiplex recording is active, the live display mode can be set to any mode (3x3, quad, PIP, Dual PIP or
full screen, etc.) without affecting the multiplex recording function.
In VCR playback mode, cameras can be displayed in 3x3, quad (dual page), PIP, dual PIP, split screen,
squish screen, or full frame formats. In addition, any display may be frozen. VCR playback incorporates
digital decoding of the camera number from the tape so that monitor screen images may be updated at
the rate that images appear on the tape. The default refresh rate of the playback monitor is the playback
rate divided by the number of cameras being multiplexed. This will change when alarmed cameras or
dead cameras are present or camera priorities have been changed.
DigiLock
and Playback
In VCR playback mode, digital information is used to compensate for the poor vertical synchronization
signals frequently encountered with time lapse VCRs.
The QSP-860MPX DigiLock
decoding reconstructs the timing such that successfully decoded frames
are read into monitor display memory consistently without any “jumping”, “tearing” or other side-effects of
poor synchronization.
VCR Bypass
Many VCRs have on-screen programming menus which require a monitor for programming the VCR. The
QSP-860MPX includes a “VCR Bypass” feature which facilitates VCR programming by allowing the
QSP-860MPX VCR input (VCR’s video output) to be routed directly to the display monitor. The “VCR
Bypass” mode can also be used to directly view the VCR’s output for adjusting tracking or verifying proper
VCR connections to the QSP-860MPX.
