5.2.2 DDC Sentence
The P-8300 MkII display unit listens for all display dimming control (DDC) sentences. Sentences may come from other units on
the network by default from the MISC channel.
When a DDC sentence is received, the display unit will adjust the brightness to the new level.
Two variants of the DDC messages are supported: one with and one without the sentence status parameter at the end of
the sentence.
NOTE:
Refer to IEC 61162-1 standard for more information regarding the two variants and the DDC sentence.
NOTE:
The two dashes before the DDC message represents the sender and can be any two upper case characters from A-Z.
