QSP-860MPX: Instructions for Basic Operation and Installation
Page 5
4.
Determine the record speed (record hours format) you will use with your VCR and set up
the QSP-860MPX to work with your VCR using the “VCR Set up” and VCR Selection”
menus (see page 8).
5.
Exit the QSP-860MPX menus by pressing the DISPLAY button to exit each menu and
finally the menu system.
6.
If your VCR has internal “on-screen” menus for its set up, use the “VCR Bypass” feature
of the QSP-860MPX (see the VCR button function description on page 6) to view the
VCR’s “on-screen” menus on the display monitor.
7.
At this point, the basic configuration of your QSP-860MPX is complete. You may now
proceed to set more advanced functions as required for your installation (alarms, camera
labels, multiplexing options, etc.). Refer to the “Advanced Function Menus” starting on
page 9 for detailed information for the feature(s) you require.

The eight camera input BNC connectors are labeled “DUAL/LOOP” since they serve two purposes. The
factory default configuration is “DUAL” and each BNC is an independent camera input (75 Ohm
termination is ON). Four DIP switches inside the unit (see section below) determine whether each pair of
inputs are independent (“DUAL”) or used as a loop-through (“LOOP”).
Connect the “VCR IN” BNC to the video output of the VCR and the “VCR OUT” BNC to the video input of
the VCR. The alarm connector is a standard DB-15 which will mate with an alarm wire adapter board or
standard computer-type cable. See page 18 for further alarm connection information.

The video line termination switches for each camera input are located in the rear of the unit and are
accessed by removing the top cover. The switches are in the order shown above when looking toward the
back panel. The above switches are shown in the factory default settings (camera loop-through OFF, 75
Ohm terminations ON). When turned on, camera loop-through connects together the camera inputs on
the same switch (i.e. the left-most loop-through switch connects camera 4 to camera 8). When an input is
in “loop-through”, the QSP-860MPX is unable to recognize that the two loop-through inputs are the same
camera image. For multiplexing to behave as expected, one of the two loop-through inputs should be
disabled using the on-screen QSP-860MPX “Sequencing set up” menu (see pages 10, 11
Dip switch positions 2 and 3 on all four groups of switches (SW1 through SW4) control the application of
the 75 Ohm termination impedances for each of the eight camera inputs. The above switches show the
factory default position where all eight camera inputs are terminated with 75 Ohm impedances. Also note
that there is an additional termination switch for the VCR input which is on position 4 of SW 4.
