Closed Captioning
The painter deals with CC-decoding. The Painter gets its video signal directly on pin 31
(from the HIP).
The RGB-outputs are available on pins 46/47/48. Fast blanking is realized via pen 52.
I 2 C
In the N8-chassis with Painter-processor there are two I2C-busses used:
• Slow (max. 100 kHz) hardware I2C-bus (called I2C1) used for all IC
communication.
• Separate short bus (called I2C 3) for the Non Volatile Memory (NVM) to avoid
data corruption.
NVM
The Non Volatile Memory contains all set related data that must be kept permanently,
such as:
• Software identification.
• Operational hours.
• Error-codes.
• Option codes.
• All factory alignments.
• Last Status items for the customer + a complete factory recall.
