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.

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. (3+14+0+0+0+0)+4=CHKSe

Command plus offset. (14+4)

Address of projector plus offset.
