does not uniquely determine the upper and lower voltage limits.
An input range of 10 V could mean an upper limit of +10 V and
a lower of 0 V or an upper limit of +5 V and a lower limit of
-5 V.
The combination of input range, polarity, and gain determines
the input limits of an analog input channel. For some boards,
jumpers set the input range and polarity, while you can program
them for other boards. Most boards have programmable gains.
When you use SCXI modules, you also need their gains to
determine the input limits.
interrupt A signal indicating that the central processing unit should
suspend its current task to service a designated activity.
I/O Input/output. The transfer of data to or from a computer system
involving communications channels, operator interface devices,
and/or data acquisition and control interfaces.
