Positive and negative pin voltage values with LJTickDAC and U3-HV.

I have a device here, an amplifier, that I'm trying to send voltage input to using my LabJack U3-HV and LJTickDac. No problem sending voltages I just have more of electrical engineering type question. This is a very basic level question as I'm a programmer and not an electronics guy. Based on this pinout page picture, can anyone tell me if I need to send a positive voltage to the positive pin via DACA and equivalent negative voltage to the negative pin via DACB? The way I tried it was sending the same voltage to each DAC port but that did not seem to have any effect. Is it necessary to use that 5v pin on the Dac?
