We are having NI PCI-6220 Card mounted on PCI-Raiser Card in a mini windows PC. We are using 8 Digital Input Channels P1.4-P1.7 and P2.2-P2.5 for taking some inputs from our Input Card.
When the computer is on then everything is working fine and we are getting Digital Inputs in Labview. The problem is that when computer is turned off the Digital Inputs on PCI-6220 Card start drawing current and due to this voltage regulator IC on our input card starts to Heat up.
This problem only occurs when the PC is turned off , in on state everything works fine.
We will be greatful is anyone can suggest a solution to our problem.
