RS422
An EIA serial digital interface standard that specifies the electrical characteristics of balanced
(differential) voltage, digital interface circuits. This standard is usable over longer distances than
RS-232. This signal governs the asynchronous transmission of computer data at speeds of up to
920,000 bits per second. It is also used as the serial port standard for Macintosh computers. When
the 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 port
The communication interface is equipped with a master USB port, type “ A ” connector. This USB port will
simplify the service procedures for firmware updates or for downloading the log files without a network
connection.
If the only file on the USB device is the firmware file (a “ *.fw ” file), the projector will automatically start one of
the following processes.
• cornet<version nr>.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.
