Start sequence
When the projector is in standby, the Cyclone (I30) and the processor are powered. During the con fi guration of the Cyclone, a red
LED is on. It turns off when the con fi guration is loaded.
When going from standby state to active state, the rest of the PMP is powered and both FPGA’s (PIP and WARP) are getting
con
fi gured. A red LED is indicating this stage. After the con fi guration is loaded, both red LEDs are turned off.
