Local Area Network (LAN: 10/100/1000 base-T)
Local Area Network (LAN: 10/100/1000 base-T) with built-in Ethernet switch (port I and port II, reference 7 image 7-4). Use
for projector control and automation. E.g. Touch Panel, content server, ... (not for content streaming!)
As there is a need to daisy chain projectors when they are on an Ethernet network, an Ethernet switch is built in. the incoming
network is hereby available for the internal PC and for the next device in the chain. In this way a 'star' network interconnection
can be avoided. The switch used is a stand alone 10/100/1000Mbit Ethernet switch. This assures no influence on the
network speed. Furthermore, this Ethernet switch remains operational when the projector is in Standby mode.
The connectors used for these 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).
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).

• Stores Barco IP address and host name
• Handles reporting of errors, version info & Barco logs to Communicator
• Controls ICP board
• Controls Dolby 3D color wheel
• Controls and monitors keypad (Button module)
• Controls and monitors status lights
• Stores Macro files, Input files, Lens files, 3D files and Light Sensor Calibration file (LSC)
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 your DP2K-E series projector projector. This way you can configure and control your DP2K-E series projector 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.
