Does anyone have the RS-232 codes for the Sony STR-DA5500ES?

I have an RTI T3-V that I'm working on and I cannot find the rs-232 protocol documentation for this receiver.

Thanks in advance,
Chuck

They are in the files section, if this does not have what you seek let me know and i will see what else i can find.

I found this file before, but I suppose I was looking too hard. I was looking for the rs232 codes by name strda5500es versus sony receivers, etc... I'll give this a try.

Thanks for clearing it for me,

Chuck

...and sorry for the late response, I expected RC to send an e-mail notice... ahh well,

Thanks again,
Chuck

Hi, I am also looking for serial codes for a Sony receiver (STR-DA5300ES). I have looked at the files that describe the protocol, but unless I am reading it wrong, it seems that I need to manually create the required strings and calculate the checksum values using the checksum calculator for each function.

I can only assume someone has done this already, and there is a spreadsheet somewhere with all of the required codes and their functions neatly listed.

Alternatively, if some nice soul happens to have the appropriate serial codes for an MSC400, that would be even better.

Saving either of those, can I post said spreadsheet once I have created it myself?

Thanks all

I have the same problem, no matter what I do, I cannot get any commands to execute on my STRDA5500ES. The receiver is in "Installer Mode - RS232"; I have tried with and without null-modem. I have copied a simple command from the file listed above (one of the examples) and nothing works - so frustrating.....

Any help would greatly appreciate,

Chuck

The unit does indeed require a null modem when controlling it from an RTI processor. The settings are Baud 9600, Data bits 8, Stop bits 1, Parity None. Also make sure you have the proper port selected as well. When entering the string onto the button make sure you press the Hex button first before putting in a string. An example command for Main Zone off would be 02 04 A0 60 00 00 FC. Hopes this helps.

Null modem adapters should be in everybody's bag of tricks.

Thank you, this has been most helpful in getting started.

The hex command (02 04 A0 60 00 00 FC) turned off my main room - successful!

In reviewing the Sony control protocol specification (listed on this site), I am have a difficult time understanding how you derived the hex code. I understand that 00 is the main room and 00 is off. If you could spare some time to explain, I would greatly appreciate it.

Thank you,
Chuck

Before I try to do all of that, what codes are you needing just to start off and make your system functional. If you tell me I might be able to post them as there are quite a few for this piece.

Thank you,

It's operating now and I am controlling it easily with IR - however, I want to do away with IR and use RS232 only.

You have given me "main room off" which works well. I need the following to get functional with RS232.

Main room on
Main room input
Main room mute
Zone 2 input
Zone 3 input

Explaining how you take the info from the Sony Amp/Rec RS232 Protocol document and end up with the hex command would be most helpful.

Thanks,
Chuck

I just did this very same thing. It does seem difficult at first.

Here's an example:

Main Zone Power On
0xA0 0X60 0x00 0x01 0xFB

0xA0 is the product code, I believe.

0x60 is the command (power)

0x00 is the zone (main zone)

0x01 is the function (on)

0xFB is the checksum which is calculated from the previous 4 bytes.

Likewise, to turn the Main Zone Off:
0xA0 0X60 0x00 0x00 0xFC

Notice the 4th but changes. That is is Off command. The checksum bit also changes (0xFC).

Some of the commands have more or less bytes. For example:
Main zone volume up: 0xa0 0x52 0x00 0x02 0x00 0x01 0x05

Cinema Studio EX. A:0xa3 0x42 0x04 0x14

Again, the last byte (0x14) is the calculated checksum. The sony serial code spreadsheet available at various places on the internet has the checksum calculator on the first sheet I think.

As far as the room input selection, I've gotten all of them to work, except the HDMI inputs. The codes that I've found don't include them, and my experimenting didn't produce a working result.

The device will return either ACK or NACK depending on whether or not the command was accepted.

I've uploaded a new XLS spreadsheet that shows more of the commands assembled from the Sony spec sheet, although it is not all inclusive. Perhaps it will help you out. It may take a little while to be available in the Files section however. In any case, once you see a bunch of the commands already built, the Sony list won't look so mysterious.

Here you go. I hope it helps.


HDMI1=02 04 A0 42 00 21 F9
HDMI2=02 04 A0 42 00 22 F8
HDMI3=02 04 A0 42 00 23 F7
HDMI4=02 04 A0 42 00 24 F6
HDMI5=02 04 A0 42 00 25 F5
HDMI6=02 04 A0 42 00 26 F4

Thanks, I will update the spreadsheet. I was certain that I tried these, as they are simply a continuation of the existing codeset (5.1 input is the last one shown ...0x20, 0xFA), but perhaps there was something else at play with the unit I was experimenting with.

Thanks again.

@ Mr. Mod
I have all codes (RS_232) for the Sony DA5300 which work perfectly!  except "Tuner" {02,04,A0,42,00,00} and a Checksum was not necessary in the MSC-400 on any codes issued...Have any insight or corrections?
