Sets up a multiplexed module for a single channel analog input operation to be performed by 
the given DAQ device. Sets the module channel, enables the module output, and routes the 
module output on the SCXIbus if necessary. Resolves any contention on the SCXIbus by 
disabling the output of any module that was previously driving the SCXIbus. You also can use 
this function to set up to read the temperature sensor on a terminal block connected to the front 
connector of the module.

moduleChan is the channel number of the input channel on the module that is to be read.

Range:

0 to n–1, where n is the number of input channels on the module.

–1:

Set up to read the temperature sensor on the terminal block connected to the 
module if the temperature sensor is in the MTEMP configuration.

DAQdeviceNumber is the device number of the DAQ device that will perform the analog 
input. If you will use the SCXI-1200 to perform the analog input, you should specify the 
module logical device number.
