Hi, I am working with a NI usb-6210 and so I don't have any analog ouptut channels that I can utilize. I'm hoping I can use the digital output for my application since I'm trying to create a switch with which I can syncronize my experiment setup. I need to output 5V in order for my device to run and currently I am only able to get 1V.

The 6210 can put out 16mA on a single digital output. So if you are only seeing 1V, then whatever you are connected to has a load impedance of around 60 Ohms. Taking that up the 5V would need over 80mA of drive. So you will need a logic buffer that can supply at least that. I would aim for something more like 100mA current capability. Do a search on Digikey and I'm sure you'll find something that works for you.

Yeah, shortly after I posted the question I found another post about the same issue. it took a google search for the problem instead of the NI forum search. I figured it out. Thanks for your help!
