About DAC output voltage, AD-FMCDAQ2-EBZ + ZC706 + IIOoscilloscope

Hi I have some questions about using DAC in AD-FMCDAQ2.

first of all I using DAQ2 with ZC706 and IIOoscilloscope. When use IIO the only thing what i do is change The DDS mode one tone mode to DAC buffer output mode  (I made some data set at MATLAB, data are complex double and have -1 to +1 range).

Question:

1. What is the range of output? I think it is -0.6 ~ +0.6V am i right?

2. I will connect the DAC to some LED drive circuit for Transmit the signal via light. Even if i connect some circuit, the range of output still -0.6 ~ +0.6?

If it is not, how can i calculate the range?

Those might be simply questions but hard for me who are undergraduate student.

    ADI High  DACs provide an output current as opposed to an output voltage. This current can drive any resistive load, including a short circuit, as long as the voltage developed at the DAC output pin (when referenced to ground) does not violate the DAC output compliance specification.  For the AD9144, this voltage range is -250mV to +750mV.
