• Handles reporting of errors, version info & Barco logs to Communicator
• Controls ICP board
• Controls Dolby 3D color wheel
• Controls and monitors keypad
• Controls and monitors status lights
• Stores Macro, Input, Lens file, 3D file and LSC file.
Prior to replace the Cinema Controller board try to read out the SMNP key. Use for that the Communicator
software. In case it is not possible to read out the SNMP key a new SNMP key has to be requested. See chapter
"Request for new SNMP key" in the user guide of the Communicator software.
When inserting a new Cinema Controller board the SNMP key must be reprogrammed in the new board and the
Dallas key must be re-identified with the new board. See user guide Communicator for precise instructions.
Ethernet network communication
The DP2K-12C/11CX projector can be connected to a LAN (local area network) using one of the 10/100/1000 base T ports on the
communication interface. Once connected to the LAN, users are capable of accessing the projector from any location, inside or
outside (if allowed) their company network using the control software (Communicator touch panel). This toolset locates the projector
on the network in case there is a DHCP server or the user can insert the correct IP-address of the projector to access the projector.
Once accessed, it is possible to check and manipulate all the projector settings. Remote diagnostics, control and monitoring of
the projector can then become a daily and very simple operation. The network connectivity permits to detect potential errors and
consequently improve the time to servicing.
As there is a need to daisy chain projectors when they are in Ethernet network, an Ethernet switch is build 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 avoid.
The switch used is a stand alone 10/100Mbit Ethernet switch. This assures no influence on the network speed. Whenever a slow
(10Mbit) device is connected the speed between the 100Mbit devices remains 100Mbit.
