SWITCHES
The first step in setting card addresses is to identify the
correct address for the card in question. When systems
are shipped, each card will be marked on the front edge
with the camera input numbers.
CAUTION:
The Matrix 44 circuit boards contain
A
integrated circuits
that are sensitive to static
electrical discharge. Take all necessary precau-
tions (including use of grounding equipment
such as ground straps and conductive work pads)
to avoid static discharge which can destroy
A.l.l.l
System
In a single-card-cage system, only the
cards require addressing. Looking at the card cage from
the front, the left card is addressed for video inputs l-8,
the second card 9-16, and so on. The sixteenth card
from the left is addressed for inputs 121-128.
A.1.1.2
l&Monitor System
A system with up to 128 camera inputs and from 9 to 16
monitor outputs occupies two card cages. In this con-
figuration, each camera input into a
card
in the the master card cage (the cage with the CPU) is
also looped out and routed to a camera input in a
card in the second card cage. Thus, the
switcher cards in the slave card cage will have the same
address as the corresponding card in the master card
cage. Refer to Figure A-2.
A.1.1.3
System
A
system with 17-24 monitor outputs
requires three card cages, one master and two slaves.
Switcher card addressing of the second slave follows the
procedure described in Section A. 1.1.2 for the primary
slave. Refer to Figure A-2.
The address for each
card is set on DIP
switch
Refer to Figure A-3 for the location of the
DIP switch. Place the
card on a static-free
work surface before beginning work.
The switch has eight positions; only positions one
through five are used to set addresses in VPS1344
systems. Refer to Table A-l for switch settings. A
numeral “1” in the table indicates ON; a
indicates
O F F .
NOTE:
DIP switches found on
cards
may have the numbers oriented right-side-up or up-
side-down as you hold the card in the position shown
in Figure A-3. This does not affect the addressing
procedure. Simply set each switch ON or OFF as
indicated in Table A-l.
