Someone please help me to understand how serial protocol work for this unit.

For example for my Jvc DLA projector

Power - Off is 21 89 01 50 57 30 0A

Clear.

I've found an XLS file from Onkyo formatted something like:

Code Means
"00"Set System Standby

etc

in this case Standby control is only 00?

Thanks

Poor Guy. It sounds like you only got the half of the protocol sheet. Onkyo (and Integra) use prefixs for commands, then have an actual function that gets appended (ass-ended?) to the prefix. 00 is the off function command, but the player doesn't know what to do without the prefix.

This should all be documented in the protocol sheet. What did you find?

Here is the full command:

!7PWR00
0101001101111001011100110100100101101110011101000110010101100111011100100110000101110100011010010110111101101110

!7PWR00

Here is a character by character breakdown:

! = start command (lets the RS232 receiving device know what follows is a command. Its a delimiter between any other noise on the line or maybe if it is still listening for a CR/etc, it knows this is new information.

7=Destination Unit (dvd, receiver, etc). As the command structure is essentially the same across all their devices, in case you had a rs232 chain or something, this number lets the dvd player know to listen and not the receiver. {1 is receiver, 2 is DVD, 7 is Bluray}.

PWR = Command (tell the unit which command it is about execute.

00= Parameter (now that it knows to start (!) and that the command is designed for it (7) and which command it should use (PWR) then 00 tell the device what to do with that command. The contrast would be 01 for on and 02 for toggle.

Integra/Onkyo also use a CR as a end of character. My control system sends it automatically. What are you using?


As another example, take the colored buttons for Bluray.

The prefix would begin as:

!7CBC

then the parameters would be:

AB = A
BB = B
CB = C
DB = D

Look at the protocol tab in the excel spread sheet, then go to the command and parameter tab.
0101001101111001011100110100100101101110011101000110010101100111011100100110000101110100011010010110111101101110

!7PWR00 != 2D 1F 00 04
!7PWR00 = 21 37 50 57 52 30 30

Take a look at ASCII, HEX, and binary encoding schema. All three have characters that are equivalent to each other.

21 hex = ! ASCII and so forth.

Once you understand the schema a bit the protocol manual is easier to figure out.
No, it doesn't come preprogrammed.

Now it'c clear (i think), for Playback, as example, i've:

ASCII !7SST01

HEX 21 37 53 53 54 30 31

for command UP:

ASCII !7OSDUP

HEX 21 37 4f 53 44 55 50


Thanks
