Can I get current output from the same point for 2 different applications?

[LABVIEW TECHNICIAN]

I'm using NI DAQ 6024E and CB-68LP as a connector block.One of my program gives output at pins 55(AO Gnd) & 21(DAC 1 OUT) and the other at pins 54(AO Gnd) & 22(DAC 0 OUT).I want to merge both the outputs at pins 55 & 21 so that when I run any of the programs, I get output at the same pins.What configurations do I need to make for the above changes?

You could either revise one of your VIs to use the other output pin, or you could use diodes to combine the two pins. The diodes are for isolation between the two outputs. If output is positive, connect diodes, anode end, to each output. Connect both diode cathodes together. This will combine the two outputs into one line. There will be an approximate voltage drop of 0.7 volts across the diode. So take that into consideration when defining your AO output voltage.

I dont have the original VIs of any of the programs.So the only thing i can do is modify the output connector board properties or DAQ card properties.Isn't there any better solution by which i can just modify the properties and it'd work?

Hello,

The best techniques are the one suggested by TBOB. There are no DAQ properties that would externally change the output of the pins unless you can find the block diagram and use Route Signal.vi.
