FPGA I/O Node

Use an FPGA I/O Node configured for reading with this device.

Terminals in Software

Use the FPGA I/O Node to access the following terminals for this device.

Table 277. Terminals in Software
Terminal Description
AIx Analog input channel x, where x is the number of the channel. The NI 9252 has channels 0 to 7.
Onboard Clock Gives access to the onboard clock in the LabVIEW block diagram. The Onboard Clock frequency is 12.8 MHz.

Use the FPGA I/O Node in a single-cycle Timed Loop to access this channel. Export the Onboard Clock of the NI 9252 to access this channel.

Start Channel that controls when the NI 9252 starts acquiring data.

If TRUE is written to the Start channel, the NI 9252 starts acquiring data. When the NI 9252 is acquiring data, write TRUE to the Stop channel before you can access properties information for the module.

If FALSE is written to the Start channel, no operation is performed.
Stop Channel that controls when the NI 9252 stops acquiring data.

If TRUE is written to the Stop channel, the NI 9252 stops acquiring data. When the NI 9252 is acquiring data, write TRUE to the Stop channel before you can access properties for the module.

If FALSE is written to the Stop channel, no operation is performed.

Arbitration

This device supports only the Arbitrate if Multiple Requestors Only option for arbitration. You cannot configure arbitration settings for this device.

Module Properties

Use the FPGA I/O Property Node to access the following module properties for this device.

Table 278. Module Properties
Property Description
Data Rate Sets the rate at which the NI 9252 acquires data.
Module ID Returns the module ID.
Serial Number Returns the unique serial number of the module.
Vendor ID Returns the NI vendor ID, 0x1093.
Filter Response Sets the AI filter types supported by the device. The filters supported by this module are the Comb (default) and Butterworth filter.
Filter Order Sets the Filter Order for the Butterworth filter. This setting would only take effect if the module is currently configured to the Butterworth filter.
Filter Frequency Sets the AI filter's cutoff frequency.

Single-Cycle Timed Loop

This device does not support the single-cycle Timed Loop.
