R5911443 /02 UDM 43RS422An EIA serial digital interface standard that specifies the electrical characteristics of balanced(differential) voltage, digital interface circuits. This standard is usable over longer distances thanRS-232. This signal governs the asynchronous transmission of computer data at speeds of up to920,000 bits per second. It is also used as the serial port standard for Macintosh computers. Whenthe difference between the 2 lines is < - 0.2V that equals with a logical '0'. When the difference is >+0.2V that equals to a logical '1'..USB portThe communication interface is equipped with a master USB port, type “A” connector. This USB port willsimplify the service procedures for firmware updates or for downloading the log files without a networkconnection.If the only file on the USB device is the firmware file (a “*.fw” file), the projector will automatically start one ofthe following processes.• cornet.fw: The projector will upgrade or downgrade, depending on the version number.• LogExtractor.fw: The log files will be downloaded.Make sure that any used USB-stick is FAT32 compatible and contains no other files or folders.4.4 LED and Button indication chartButton Backlight StatusButton Color status DescriptionStandby button Blinking WHITE (slow) Projector starts up (booting)Blinking WHITE (fast) Firmware upgradeSolid WHITE Projector is in Standby modeBlinking BLUE Projector goes to ON modeSolid BLUE Projector is ONBlinking RED Error conditionShutter button Off (no color) Projector is OFF, starts up, or is inStandby mode.Solid WHITE Projector is ON, shutter is openSolid RED Projector is ON, shutter is closedLED StatusLED Color status DescriptionPWR (power LED) Off Projector powers upRED Projector is in StandbyORANGE Projector is ReadyGREEN Projector is onInput & Communication
