INSTALLATION and INTERNAL SETUP
AD1476
INSTALLATION
This installation should be made by qualified service personnel
and should conform to all local codes. Safeguards must be
taken to avoid unintentional operation by employees and
maintenance personnel working about the premises, by falling
objects, by customers, by building vibration, and by similar
causes.
Mounting
Tabletop and rack-mount models are available and may be
mounted in a convenient location near associated monitors.
Tabletop models are 1.88" high and 17" wide. Rack-mount
models are denoted with the suffix "R" and are designed for use
in standard EIA 19" racks and are 1.75" high and 19" wide.
Avoid heat sources or poorly ventilated racks. Operating
temperatures must be held within a reasonable range to ensure
proper operation.
CAUTION - Due to the presence of non-insulated
components with hazardous voltages, the
following internal adjustments should be
performed by qualified service personnel only.
INTERNAL SETUP
Before connection and operation of the SuperQuad HR, internal
jumpers (see Figure 2) may need to be reset for specific user
requirements. These jumpers are factory set for most user
needs, as indicated below and in Figure 2.
Color Filters - Jumpers J4, 27
The SuperQuad does not pass color signals to the Quad output.
In order to use signals from color cameras as inputs to the
SuperQuad, it may be necessary to reduce the color sub-carrier
interference. Internal filters are provided and may be activated
by moving internal jumpers. These filters do not affect color
signals on a full-screen Call output. The factory setting of these
jumpers is "OUT", for black and white cameras.
Jumper J4 reduces the color sub-carrier interference from
Video Inputs 1, 5, 3, and 7; J27 reduces the color sub-carrier
interference from Video Inputs 2, 6, 4, and 8.
Vertical Lock - Jumper J3
The video output of the SuperQuad can be vertically locked to
either the AC line or to Video Input 1. As shipped, it is locked
to the AC line. It can be locked to Video Input 1 by moving the
SYNC jumper (J3) located on the PCB.
Expand Sync - J29
When using certain video cassette recorders, it may be
necessary to place the J29 jumper in the "ZOOM" position for
increased picture stability.
