NI cDAQ-918x/919x User Manual

• Panel Mounting without a Panel Mount Kit—Threaded holes are located in the cDAQ

chassis for mounting it to a panel. Use two standard #6-32 UNC-2B machine screws with

a maximum threaded engagement length of 4.83 mm (0.190 in.) to go through the panel and

into the back of the chassis, as shown in Figure 1-10. National Instruments does not provide

these screws with the chassis. Refer to the specifications document for your cDAQ chassis

for mounting dimensions.
