6. Input & Communication
The connectors used for all Ethernet ports are of the type RJ45, which is compatible with standard RJ45 cable
connector. Straight (most common) as well as cross linked network cables can be used. The 2 ports are
functionally identical. Both ports are connected via the projector switch (Auto sensing enabled).
Virtual comport (RS232 serial communication)
The USB-IN port of the communication interface supports RS232 serial communication. You can use the RS232 input port to connect
a local PC to the projector. This way you can configure and control the projector from your local PC.
Do not forget to set the projector's baud rate (default = 115200) to match that of the computer.
Advantages of using RS232 serial communication:
• easy adjustment of the projector via PC (or MAC).
• 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 and +3V is the transition zone.
