Wake up projo
You choose offset. This is added to the
rest of the bytes so that none of them equal
2 which would make the projector think its
being told to wake up again. Normally
this is 0. It is set to 4 in this working example
to show how it affects the value of the rest
of the bytes.
Address of
projector plus
offset.
Command plus offset.
(14+4)
Optional data bytes plus
offset. No data needs to be
sent to turn on projector
therefore these are equal to
zero and offset is then
added.
Add bytes from ADR to DAT4, keep 2
right most digits, then add offset.
