NI PXIe-1085 Series User Manual
Caution
When connecting digital voltmeter probes to the rear 8-pin connector, be
careful not to short the probe leads together.
You can use a digital voltmeter to ensure all voltage levels in the NI PXIe-1085 Series chassis
are within the allowable limits. Referring to Table 2-5, connect one lead of the voltmeter to a
supply pin on the 8-pin remote voltage monitoring connector on the rear panel. Refer to
Table 2-4 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 2-5.
Note
Use the rear-panel 8-pin connector to check voltages only. Do not use the
connector to supply power to external devices.
Table 2-4.
