RS232/RS422 input
The communication interface of the HDX projector supports RS232 and RS422 serial communication on two different types of input
connectors. The left one a Sub-D connector, the right one an USBB connector acting as RS input when connected to an USB input
of a PC.
You can use the RS232/RS422 input to connect a local PC to your HDX projector. By this way you can configure and control your
HDX projector from your local PC.
Do not forget to set the projector's baud rate to match that of the computer.
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
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 and +3V is the transition zone.
