Hi there, I have a LabJack U12 interface card that has two analogue outputs, AO0 and AO1. What I would like to be able to do is set up LabVIEW V6.1 to eventually control the dimming of some external lights, from say a simple control on LabVIEW's front panel. I will have some external circuitry connected to the interface card to perform the dimming of the lights, so all I will require is a variable voltage on the output of the card. I think the specification of the card is 0 to +5 volts for the two analogue outputs. I have tried looking on the website for LabJack (www.labjack.com) for any ideas, but with no success! Please find my LabVIEW file as an attachment. I would be very grateful for any help on this matter, Neil Sampson."

Attached is a very simple example VI that uses EAnalogOut to update AO0 and AO1 based on two knob controls. See if this helps.

Hi there, Just a small note to thank you for taking the time out to help me. The example vi you gave me is perfect for my application. Thanks again, Neil Sampson (MM1FHS).
