The INP PCA obtains its operating power directly
from
the
com-
puter
system
power
supply.
All HP 3000 HP-IB Version Computer
Systems have an adequate power supply
to
accommodate
the
add-
ition
of
an INP or multiple INPs without the need for any power
supply modification.
2-4. PCA Jumpers and Switches
The jumpers used on the INP PCA board have all been preset during
board calibration at the factory,
and no field
alterations
are
required.
There is, however, the HP-IB address switch (a single
rotary switch), which must be manually set to configure the INP
for your specific system and application.
Figure 2-1 shows the location of this switch.
Set the HP-IB address switch as follows before installing the
PCA board in the computer card cage.
The
HP-IB
address switch is a thumbwheel switch with
eight
numbered positions (0 through 7).
The setting of this switch
identifies the device number assigned to this INP and is read
by the processor.
Rotate the switch to display
the
appro-
priate number,
as described below.
