3. Input & CommunicationYou can use the RS232/RS422 input to connect a local PC to your XDL series projector. By this way you can configure and controlyour projector from your local PC.Advantages of using RS232/RS422 serial communication:• easy adjustment of the projector via PC (or MAC).• allow storage of multiple projector configurations 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).RS232/422 input (Sub-D) portPin Description1 DCD : Data Carrier Detect2 RXD- : Receive Data3 TXD- : Transmitted Data4 DTR : Data Terminal Ready [RS232]TXD+ : Transmitted Data [RS422]5 GND : Ground6 DSR : Data Set Ready [RS232]RXD+ : Received Data [RS422]7 — (not connected) —8 CTS : Clear To Send9 RI : Ring IndicatorRS232An 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 forrelatively short-range communications and does not specify balanced control lines. RS-232 is a serial control standardwith a set number of conductors, data rate, word length and type of connector to be used. The standard specifies com-ponent connection standards with regard to computer interface. It is also called RS-232-C, which is the third versionof 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.RS422An 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 asyn-chronous transmission of computer data at speeds of up to 920,000 bits per second. It is also used as the serial portstandard 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 portThe communication interface is equipped with a master USB port, type “A” connector. This USB port will simplify the service proce-dures 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.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.26 R5906151 XDL 17/04/2018
