In LabVIEW, can I use different input limits for the same
SCXI-1102/B/C channel if I repeat the channel in the SCXI channel
string array?
No. You cannot dynamically change the SCXI-1102/B/C gain settings
during scanning. Therefore, group channels with similar input ranges
together in the channel string array. Make sure that repeated channels in
different indices of the channel string array have the same input limits in
the corresponding input limits array.
In LabVIEW, can I use a VI to change my SCXI-1102/B/C
configuration settings?
Yes. In Traditional NI-DAQ (Legacy) you can use the AI Parameter VI to
change all the SCXI-1102/B/C configuration settings. You also can change
the configuration settings in NI-DAQmx using
NI-DAQmx Tasks
.
Are there any cabling restrictions when using an SCXI-1102/B/C
module with a plug-in E/M Series DAQ device?
Yes. If a chassis contains an SCXI-1520, SCXI-1530/1531, or SCXI-1140
module, at least one of these modules must be the cabled module. A cabled
module is the module connected directly to the E/M Series DAQ device.
This ensures that a timing signal is available for use by all
simultaneous-sampling SCXI modules in the chassis.
Is a register-level programming manual available for the
SCXI-1102/B/C?
NI does not support register-level programming for the SCXI-1102/B/C.
What is the power-on state of the SCXI-1102/B/C multiplexer, analog
bus switches, and configuration settings?
The multiplexer, analog bus switches, and configuration settings are not
in a known state immediately after power on. All hardware settings are
programmed automatically when beginning an acquisition in LabVIEW
or a test panel in MAX.
Which accessories can I use to connect signals to the front of the
SCXI-1102/B/C module?
Refer to Chapter 1,
, for more information.
