NI 5772 Adapter Module PC Connection

I am new to using FPGAs and new to using the NI 5772 Adapter Module.

I do not own the NI FlexRio FPGA but I do own a  KC705 Xilinx FPGA and wanted to know the best way to connect the Adapter Module to my PC.

In the NI 5772 manual it reads:

"The AUX I/O connector accepts a standard, third-party HDMI cable, but the AUX I/O port is not an HDMI interface. Do not connect the AUX I/O port on the NI 5772 to the HDMI port of another device."

Is it safe to connect this to my PC via an HDMI cable or is there a better/safer way to receive the digitized data?

Any help would be greatly appreciated, thanks for your time.
