POWER LED

The POWER LED is lit while the NI-9157/9159 is powered on. This LED is a bi-color LED. When the chassis is powered from V1, the POWER LED is lit green. When the chassis is powered from V2, the POWER LED is lit yellow.

USER FPGA LEDs

You can use the bi-color, yellow and green USER FPGA LEDs to help debug your application or easily retrieve application status. Use the LabVIEW FPGA Module and NI-RIO software to define the USER FPGA LEDs to meet the needs of your application. Refer to LabVIEW Help for information about programming these LEDs.

Configuring DIP Switches

All of the DIP switches are in the OFF position when the chassis is shipped from National Instruments.

NO FPGA APP Switch Push the NO FPGA APP switch to the ON position to prevent a LabVIEW FPGA application from loading at startup. The NO FPGA APP switch overrides the chassis powerup options described in Configuring the NI-9157/9159. After startup you can download to the FPGA from software regardless of switch position.
USER FPGA Switches You can define the USER FPGA switches for your application. Use the LabVIEW FPGA Module and NI-RIO software to define the USER FPGA switches to meet the needs of your application. Refer to LabVIEW Fundamentals for information about programming these switches.

NO FPGA APP Switch

Push the NO FPGA APP switch to the ON position to prevent a LabVIEW FPGA application from loading at startup. The NO FPGA APP switch overrides the chassis powerup options described in the section on chassis powerup options. After startup you can download to the FPGA from software regardless of switch position.

USER FPGA Switches

You can define the USER FPGA switches for your application. Use the LabVIEW FPGA Module and NI-RIO software to define the USER FPGA switches to meet the needs of your application. Refer to the LabVIEW Help for information about programming these switches.
