A.2 Barco Digital Cinema Projectors
Configuration:
Series 1 Projector:
Series 1 projectors listen on TCP port 43680 for incoming connections. The Series 1 DP projectors
(DP100, DP90, DP1200, DP1500, DP2000, DP3000), have two IP addresses. One for the main
projector controller and one for the Texas Instruments DLP Cinema® front end. The IP address of the
projector (main controller) should be used.
Series 2 Projector:
Series 2 projectors listen on TCP port 43728 for incoming connections. The Series 2 projectors have a
single IP address.
In addition to user messages, the eCNA has built-in support for acquiring projector status. This
status is available to CAI clients. In order to get status, Device Communications and Poll for Status
must be Enabled. The Poll Interval is the time interval in seconds that the projector is polled for
status. The range is 2 to 60 seconds. 10 seconds is the default. If status is not required for the
application, it is best that Poll for Status remain Disabled.
Command Messages:
This is a list of commonly used control commands. The user only needs to enter the command
bytes(s) and any data bytes if applicable. The eCNA automatically inserts the Start byte, Projector
address, Checksum byte and Stop byte. A default Barco configuration file is available from EPRAD.
