Accessory Auto-Detection; Table 2-5. Adc Conversion Rates - National Instruments SC Express PXIe-4357 User Manual

Use the following equation to determine the ADC conversion rate and timing mode based on a
given sample rate:
ADC Conv Rate
You can determine the ADC timing mode by coercing the ADC conversion rate to the next
largest rate using the values in Table 2-5.
ADC Timing Modes
1 (High Resolution)
9 (High Speed)
*
ADC timing mode 1 is the default setting for the On-Demand timing mode when the ADC Timing
Mode property is not explicitly selected.

Accessory Auto-Detection

NI SC Express modules automatically detect compatible accessories or terminal blocks.
The RSVD pins on the I/O connector provide power to the accessories as well as digital
communication lines. This allows software to detect when accessories are inserted or removed.
In addition, software can automatically identify the specific terminal block as well as access any
calibration or scaling information associated with the terminal block.
Measurement & Automation Explorer (MAX) allows you to see the accessories connected to
your device. In MAX, expand Devices and Interfaces and locate your device. If a terminal block
is connected to your device, it will be displayed beneath the device. Unsupported terminal blocks
appear in MAX with an X next to them.
NI-DAQmx property nodes can be used to programmatically access information about
connected accessories in your application. Refer to the NI-DAQmx Help for documentation on
programmatically accessing accessory status. Select Start»All Programs»National
Instruments»NI-DAQ»NI-DAQmx Help.
