RS232 input
The communication interface of the PFWX-51B/PFWU-51B projector supports RS232 serial communication.
You can use the RS232 input to connect a local PC to your PFWX-51B/PFWU-51B projector. By this way you can configure and
control your PFWX-51B/PFWU-51B projector from your local PC.
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 communication 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 component 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.
