5. Input & Communication
• easy adjustment of the projector via PC (or MAC).
• allow storage of multiple projector con fi gurations and set ups.
• wide range of control possibilities.
• address range from 0 to 255.
• sending data to the projector (update).
• copying data from the projector (backup).

RS232
An Electronic Industries Association (EIA) serial digital interface standard specifying the characteristics of the commu-
nication path between two devices using either D-SUB 9 pins or D-SUB 25 pins connectors. This standard is used for
relatively short-range communications and does not specify balanced control lines. RS-232 is a serial control standard
with a set number of conductors, data rate, word length and type of connector to be used. The standard speci
fi es com-
ponent connection standards with regard to computer interface. It is also called RS-232-C, which is the third version
of the RS-232 standard, and is functionally identical to the CCITT V.24 standard. Logical ’0’ is > + 3V, Logical ’1’ is < -
3V. The range between -3V and +3V is the transition zone.
RS422
An EIA serial digital interface standard that speci fi es the electrical characteristics of balanced (differential) voltage,
digital interface circuits. This standard is usable over longer distances than RS-232. This signal governs the asyn-
chronous 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 pro-
cedures for software updates or for taking backup
fi les from the projector without network connection. An USB-stick is plugged into
the USB port and fi les can be transferred from or to the projector using the local or remote control unit. Note that the USB-stick has
to be Linux FAT16 compatible.
