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.

1. Chassis Grounding Screw
For EMC compliance, you must connect the NI 9154 to earth ground through the chassis
ground screw. Use wire that is 2.05 mm
of 1.5 m (5 ft). Attach the wire to the earth ground of the electrode system of the facility.
Caution
connector, you must attach the cable shield to the chassis grounding terminal using
1.3 mm diameter (16 AWG) or larger wire. Attach a ring lug to the wire and attach
the wire to the chassis grounding terminal. Solder the other end of the wire to the
cable shield. Use shorter wire for better EMC performance.

Mounting the Device
To obtain the maximum allowable ambient temperature of 55 °C, you must mount the NI 9154
horizontally on a 35-mm DIN rail or a flat, metallic, vertical surface such as a panel or wall.
You can mount the NI 9154 directly to the surface or use the NI Panel Mounting Kit. The
following figure shows the NI 9154 mounted horizontally. Mounting the NI 9154 in other
orientations or on a nonmetallic surface can reduce the maximum allowable ambient
temperature and can affect the typical accuracy of modules in the NI 9154.
