Specification for front, side & rear and internal display boards

Front, side & rear and internal display boards are fully electronic without any moving parts. Smd amber LEDs combined with a wide viewing angle, uniform intensity ensure better and optimal visibility. The light intensity is adjusted through a built-in sensor, which reacts to the ambient light conditions thereby ensuring maximum readability. The display information will be taken from console unit via rs485 communication.
