Both Ethernet ports are equipped with a yellow and a green LED. The yellow LED lights up in case the port is connected with a
100Mbit network. The green LED blinks in case there is network activity.
The connectors used for both 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 hub (Auto sensing enabled).
RS232 serial communication
The communication interface of the DP2K-12C/11CX supports RS232 serial communication. You can use the RS232 input port to
connect a local PC to your DP2K-12C/11CX projector. This way you can con
fi gure and control your DP2K-12C/11CX 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.
• 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 speci
fi es 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.
GENERAL PURPOSE IN/OUT (GPIO)
This female 37 pins D-SUB connector can be used to send or receive trigger signals from other devices. These input/output pins
can be programmed by macros created via the Communicator touch panel. See user’s guide of the Touch panel, section Macro
editor, for more information about this functionality.
