2.5 VMEbus OPTIONS
The XVME-500/590 is designed to be addressed within the VMEbus Short I/O
Memory Space. Since each module connected to the bus must have its own unique
base address, the base-addressing scheme for XVME input modules has been designed
to be jumper-selectable.
will occupy a lK-byte block of Short I/O Memory Space.
The XYCOM base address decoding scheme for input modules is such that the
starting address for a module will always reside on a 1K boundary.
module base address may be set for any one of 64 possible 1K boundaries within the
Short I/O Address Space.

Selects fixed-gain amplification factor on version 1
ONLY (see Section 2.6.4.2)
Used only for modifying version 1 for resistor
programmable gain (see Section 2.6.4.3)
This jumper configuration controls gain ranges for
programmable gain amplifier (versions 2 & 3) (see
Section 2.6.4.1)
This jumper is installed to provide ground reference
for external trigger; J2 1 must be removed if this
option is used (see Section 2.6.4.5)
These jumpers are used together to determine if the
inputs will be configured as either 8 differential,
16 single-ended or 16 pseudo-differential input
channels (see Section 2.6.2)
Each jumper is used to determine settling times for
the appropriate module amplifier (see Section 3.4.1)
These two jumpers are provided to allow grounding
of an input channel in either the single-ended or the
differential input mode of operation for purposes of
calibration (see Section 2.6.5)
Connects Analog to Digital GND. J32 is jumpered
foil and can be cut if the user desires.
