In your Macropump.m1s
you need to change GetOEMled(1140) to GetUserLED(1140), there is NO OEM Leds in that range.
Also in your Brain:
You will need to INVERT your noop, for your UserLED to be ON when your Input1 is ON, you will have to use a INverted op. otherwise when the Brian says your Screen User LED is on, it will be off, and vice versa.
so you brain rung should be:
INPUT1 -> Invert signal -> UserLED
(I recommend reading the "Brains Users Guide" in the member docs section.)
BTW: make sure under Ports and Pins for the INPUT1 signal you have it enabled, AND make sure the Logic (active high, or active low), is correct for what you want the state of that signal doing when active.
