4. Input & Communication
Advantages of using RS232 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.
•
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 specifies 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 an d +3V is the transition zone.
3. 12V TRIGGER
12 V output, maximum 200mA, available when projector is not in stand by.
4. IR EXT.
Receives input signal from compatible Niles or Xantech IR repeater systems.
5. YUV1
Standard and high definition (480i/480p/576i/576p/720p/1080i/1080p) component input, connects to DVD/HD-DVD/BD
player, HD set-top-box or other SD/HD input source.Also connects to RGB input from RGBS input source.
6. HDMI
HDCP compatible digital image input; connects to sources using HDMI or DVI.
7. VGA
Standard 15-pin VGA connection socket to connect to RGB, high-definition component input or PC.The projector will
automatically detect the resolution of the input signal.
