Section 5 — Definition of Extended Maestro Commands
MAESTRO CEXT (0x3F) Common Extension
When using the Common Extension command UPDATE (0x07), Extended Maestro Com-
mands are specified within the UPDATE command by indicating the Extension Command
(0xFF) followed by the desired Extended Maestro Command. For example:
02 STX
08 Byte count
3F Common Message Extension
07 UPDATE
01 RBGN
FF Extension
40 MAESTRO_TRANSITION_TYPE
FF Extension
41 MAESTRO_TRANSITION_RATE
02 REND
CS Checksum
This would activate UPDATE for MAESTRO_TRANSITION_TYPE and
MAESTRO_TRANSITION_RATE. The RBGN/REND is necessary since this example selects
more than one command for updates.
The MUTE command would switch off all responses (Legacy and/or Maestro).
