| CockpitSquare overview | A 120-ohm, 1/8-watt metal-film resistor with ±1% tolerance. It is intended for current/voltage compensation when powering single LEDs from a 5V source, including certain simulator-panel backlighting applications. | The Backlighting Dimmer is a V4 electronic dimming circuit for controlling and adjusting 12 V DC LED cockpit backlighting. It interfaces with compatible simulator I/O boards and uses a potentiometer for brightness adjustment, with relay-based electronic switch-off. |
