2.4.7 BGxIN/BGxOUT Daisy chain
The Data Bus Arbitration signals BGxIN and BGxOUT (where " x " can be a number 0-3
to represent the three levels of arbitration)
are
not used by the AIN, and
are hardwired
together on the module to allow the
BGxIN/BGxOUT
Daisy
Chain to pass through the
backplane slot occupied by the
AIN.
In each slot
of the
VMEbus
backplane, there are
four sets of jumpers shorting the signal
BGxIN
to BGxOUT (x=0 thru 3).
Since these
signals are already hardwired on the AIN,
it is not
necessary to insert these VMEbus
jumpers on the slot occupied by the AIN.
2.4.8 Miscellaneous Jumpers
Jumper J12 enables the
output of
the
Instrumentation amplifier for test purposes only
and is left fixed in the " A " position.
