If you use the LED driver in the link I provided, connection to the RoboRio is very simple.
Because the driver is a constant current source, you can provide power to it directly from the PDB, there is no need to use a VRM to power it.

The connection to the RoboRIo is as simple as connecting the "CTRL" (D+), these are the dimmer inputs, input on the LED Driver to a digital out on the RoboRio. There is no need to connect the "DGND"(D-) as GND is provided by the power GND.
Setting the digital output low turns the LED off, and high turns it on.

EASY PEAZY!
