This unit contains two seven segment led display (E), four normal LEDs (A..D) and an IR receiver (F). The display is used to show
the status of the projector for instance the selected input number, error codes, ….
The four normal leds each have a specific function:
•

•
IR accepted (green) (B): Infrared signal is accepted (own address)
•
Sync detected (yellow) (A): There is a stable sync present on the selected input
•
Power (red/green) (D): red is projector standby, green is projector active
The IR receiver can accept RC5 code. It is positioned next to the display in order to receive the IR signal through the same red glass
as the display.
