isolated power connector and that the contact at the screw terminals is solid. Because these
outputs are electrically isolated from the NI CVS-1459RT device main supply, they require
power in addition to the NI CVS-1459RT main supply.
Runaway Startup Application
If a runaway startup application causes the NI CVS-1459RT to become unresponsive, power off
the NI CVS-1459RT and then restart it in safe mode. Restarting the NI CVS-1459RT in safe
