Details
Channel 0 is special — its LED control lines can't be remapped. This is because channel 0 uses standard green and red status LEDs (they are called SG and SR). For channel 0, reading the property always returns (-1), and writing has no effect.
All other channels use regular I/O lines of Tibbo devices. Any I/O line can be selected to be the red control line of the selected channel. By default, all control lines are mapped to the non-existent line PL_IO_NULL. Remap as needed and don't forget to configure the selected I/O line as an output — this won't happen automatically.
