RANCPU Control System Master Card
The
RANCPU
decodes all messages from classroom control panels (
RANCLASS1
or
RANCL201CP
) or remote control units (
RANHHELD
). Unless a
RANEXP
or is used, each
system must include one
RANCPU or RANBROAD
. This control-system master card
mounts in the
RANCC16
Control Card Cage and can handle control-link cable runs with
up to 60,000 pF of capacitance. See Table 3 to determine the requirements for your
system. If the capacitance per foot of the cable that you are using exceeds the maximum
cumulative distance indicated in the chart, you will have to use a
RANEXP
or
RANBROAD
in place of, or in addition to, the
RANCPU
(see “
RANEXP
” or
“
RANBROAD
” for more information).
The
RANCPU
is typically connected directly to the
RANPCSW
computer for programming purposes via the
VW
2302 cable (supplied with the
RANPCSW
).

Parts Required
1 In order to use
RANGER
software V3.30 or later, the
RANCPU
should have a label that
indicates it is an “
AXC-EM ENHANCED MASTER
” and must have 256 kilobytes of
RAM
