Control Yamaha AV amp RX-A3020 via RS232 port

[Nahshon]

OK so I have been looking at this protocol with Post and GET command all over the place (indicating these are IP traffic and LAN port commands)

Please tell me the RS232 port uses another command set I have failed to locate.

Usually devices use the same protocol for IP or 232 connections. However; if you are using a Post & GET command protocol than they must have a different protocol for 232.

Thank you Nathan, I will keep searching,

Tried just reading from Hercules with all the baud rates available, only the highest three give funny characters regardless of HEX or ASCII being enabled.

"Let's try something new" getting me into trouble here :P  (The matching onkyo didn't have integrated air play)

I found a file maybe help you (don't have Yamaha to test it)

[Nahshon Williams]

Thanks man,

I will confirm with Yamaha in the morning and make it all plain as day when I find out.

This one does look scary as well :-)

:-) doesn't scary, I was lazy to edit the file and maintain only the information you need.

all you need is to identify the name of command and its code. 

Example:

Main_Zone_On -> @MAIN:PWR=On\x0D\x0A

Main_Zone_Standby -> @MAIN:PWR=Standby\x0D\x0A

Thanks Tulio,

After your post I changed the cable and switched the amplifier on.

Baud: 9600 No Parity  or Handshake.

Here is what I got. (this Hercules output has been formatted with line breaks and carriage returns)

@MAIN:PWR=On..

@MAIN:AVAIL=Ready..

@MAIN:AUDSEL=Auto..

@MAIN:INP=AV3..

@MAIN:MUTE=Off..

@MAIN:PUREDIRMODE=Off..

@MAIN:SOUNDPRG=Sports..

@MAIN:STRAIGHT=On..

@MAIN:VOL=-62.0..

@SYS:PWR=On..

@SYS:DMCCONTROL=Enable..

@SYS:HDMIOUT1=On..

@SYS:HDMIOUT2=On..

@SYS:PARTY=Off..

@SYS:YNCAPORT=50000

I can take it from here now. 

Normally a fan of starting from hercules and then getting the protocol but the cable threw me  off this time :(

Thanks again

Nahshon

Do you know if or how I can read the Volume out of the rs232?

[Kol]

You can go to http://av.yamahaconnect.com and get the entire control API.  Yes you can read volume, you can also set, increment, and decrement the level.
