Q: How do I turn the LEDs on my Graphics Master of Graphics Client Plus on and off?

Setting the state of the LEDs high (on) or low (off) is a fairly simple task by going directly to the LED driver. Open the LED with an API call to CreateFile and the led port name (LED1: through LED3:) and the use WriteFile to set the port high or low.

We have wrapper code and a sample application available for using the LEDs here:
