Two types of differential amplifiers are available: fixed gain (version 1 of both
modules) and programmable gain (version 2 & 3 of both modules).
The fixed-gain amp offers jumper-selectable gains of xl, x10, xl00 and x1000. In
addition, the fixed-gain amp may offer resistor-programmable gain (to any number
between 1 and 1000) if a resistor (Rl0) and potentiometer (R13) are added (see
Section 2.6.4.3).
The programmable amplifier provides three ranges of jumper-selectable programmable
gains (see Section 2.6.4.-l).
and x40. Range 3: x10, x20, x50 and x100. A 32-element RAM buffer is provided
with the programmable amps to hold separate gain values for the 32 analog inputs.
Within each range, the four options are software-programmable.

any of the sixty-four 1K boundaries within the Short I/O Address Space. There are
three 8-bit registers which are used for channel status, control-setting interrupt
vector, programmable gains (versions 2 & 3 on both modules) and channel selection.
In addition, there is a 16-bit
