Dear 6826PN,
thank you so much for your post. I forsee no problems in that (please make sure the digital outputs of your daq unit match the specs of what you want to connect to it), you are able to control the 7 segmens directly (so you need 7 digital ouputs per segment), more easier is an encoder in between; you are then able to write with 4 bits to a segment, the boolean number will be converted to the correct decimal number on the 7 segment display.
Best regards,
