Error -200320 at DAQmx Start Task with a SCXI System

Primary Software: Driver Software>>NI-DAQmx
Primary Software Version: 8.0.1
Primary Software Fixed Version: N/A
Secondary Software: N/A
Hardware: SCXI>>Chassis

Problem:
When I try and run my DAQmx program with my SCXI system I get the following error -200320:


Why do I get this error and how can I fix it?

Solution:
You are attempting to acquire data from a SCXI module with simultaneous sample and hold but the module cabled to your data acquisition card does not have simultaneous sample and hold capabilities. Some SCXI modules have simultaneous sample and hold capabilities such as the SCXI 1140, SCXI 1520, and SCXI 1530/1531. If you want to acquire data using simultaneous sample and hold, the communicating module must have simultaneous sample and hold capabilities.

If it is not possible to set the system up in this way, you can turn off simultaneous sample and hold. In LabVIEW you do this with a DAQmx Channel Property Mode found in the DAQmx palette. After placing the property node on the block diagram select Analog Input >> General Properties >> Advanced >> Sample and Hold Enable as shown below. Right click on the property and select Change to Write and wire a false constant to it.
