2.
Specify the module scan list, the start channel of each module, and the
number of channels to scan on each module with the function
SCXI_SCAN_Setup
. This function accepts an array of start channels
and an array of the number of channels to scan in each module.
Therefore, it is not possible to repeat channels or use nonsequential
channels using this function.
3.
Use
SCXI_MuxCtr_Setup
to program the E/M Series DAQ device
with the correct number of channels multiplexed per scan. This
number must match the total number of channels programmed in
step 2.
You are now ready to acquire the channel data with the E/M Series DAQ
device. If you are using a multifunction E/M Series DAQ device, you can
use
SCAN_Op
to perform the scanning operation. After scanning, convert
the binary data to voltage data using
SCXI_Scale
. Refer to the
NI-DAQ
User Manual
for additional information on scanning with E/M Series DAQ
devices.
