Features:
Flexibility: PXI-8431/8 users can choose the appropriate number of serial protocols and channels according to their needs.
Compatibility: NI serial interface is compatible with standard COM ports for easy integration with existing programs.
Isolation function: Some models provide isolation function to improve system stability and security.
Application scenario:
Electronic testing: The PXI-8431/8 is used to test and verify serial communication interfaces in electronic products.
Data acquisition: Acquisition of external device data through serial interface.
Control system: PXI-8431/8 communicates and controls with external devices to achieve automation and intelligence.
Precautions for use:
Before use, ensure that the PXI chassis, controller, and serial instrument control module are properly installed and configured.
Depending on the serial protocol and number of channels used, choose the appropriate test program or write a custom test program.
When performing high-speed data transfers, be aware of data integrity and stability issues.
