5. GP6 system functional description
5. GP6 SYSTEM FUNCTIONAL DESCRIPTION
About
The F90 projector series is a high brightness single chip laser phosphor projector.
The electronics system is based on the Barco Pulse platform, which offers advanced functionality such as pixel shift and complex
warp and blend adjustments.
5.1
Electronic platform
About
There are two main electronic PCB’s in the unit; PCB Mainboard and PCB Thermal Hub Board.
In addition there is a power supply and a keyboard/display PCB, and some peripheral PCB’s, such as USB interface, IR receiver,
thermal sensors.
Calibrations and settings for the unit are saved in a SD card on the Mainboard. When replacing the mainboard, this SD card must be
transferred to the new mainboard, in order to maintain the settings for the unit. Nevertheless, some calibrations has to be performed
again, such as the Constant Light Output, (especially in multi projector setup), and Lens Shift Motors.
It is crucial that all SD card data is transferred to the replacement PCB in the event of repair. Failure to do
this will compromise system dynamic data and lead to incorrect LFM noti
fi
cations as well as possible network
control con
fl
icts.

I/O’s and processing tasks:
In the matrix below is listed the different PCB’s, and their main tasks. In order to localize a malfunction in the projector, it is an
advantage to know which function that is controlled by which PCB.
Together with the block diagram and the troubleshooting matrix, this can be a helpful tool in diagnostic.
See also the “Block diagram GP6 Platform” for an overview of the system.
