Chapter 2
Installation and Configuration
Caution
When connecting digital voltmeter probes to the rear 9-pin D-SUB (DB-9)
connector, be careful not to short the probe leads together. Doing so could damage the
power supply.
You can use a digital voltmeter to ensure all voltage levels in the
NI PXIe-1062Q chassis are within the allowable limits. Referring to
Table 2-2, connect one lead of the voltmeter to a supply pin on the remote
voltage monitoring connector (9-pin D-SUB) on the rear panel. Refer to
Table 2-1 for a pinout diagram of the remote voltage monitoring connector.
Connect the reference lead of the voltmeter to one of the ground pins.
Compare each voltage reading to the values listed in Table 2-2.
Note
Use the rear-panel 9-pin D-SUB connector to check voltages only. Do not use the
connector to supply power to external devices.
If the voltages fall within the specified ranges, the chassis complies with the
CompactPCI voltage-limit specifications.
