RS 232 control, need some help!

RS232c control?

total noob here, I have been successful at getting my Sharp TV(both IP and IR), Scientific Atlanta 8300hd dvr(IR only) and Sony STR-DA5300es receiver to work(IR only) I would like to get the receiver to work with RS232 to incorporate feedback if possible. Or should I just stick to IR? I really want to avoid things getting "out of sync".

1. Any one know what type of serial cable or have a diagram for a Sony STR-DA5300es receiver? I have a pre-made null cable as well as some cat6 and DB9/RJ45 adapters(http://www.cablestogo.com/product/02941).

2. Any help with the codes and how to input them?

Thank You.

  • Ok, well I hooked up my serial null cable and have been able to get a few functions going like (HDMI 1) which i have used to simultaneously power on the receiver and select the input, but volume up and down does not respond, however mute "on"does. I need to figure out how to toggle the mute button between on and off while assigning the functions to a single button.

    So a little progress but not a lot. I wish I were better suited to these types of things.

    Any help or suggestions is greatly appreciated.

    Shane,

    Which Device code are you using? We have a device for Sony Receiver RS232 which needs to use a Straight Thru cable. Also make sure that your baud rate settings are correct (they are listed in description field of that device).

    For your mute toggle issue.
    1. Create a macro by dragging and dropping both Mute On and Mute Off onto the same button.
    2. Click on the button
    3. In the properties window (bottom left hand side of the screen) you will see a field Toggle Commands
    4. Change that field from No to Yes.

    Now this buttons commands will be executed in a toggle order.

    Hope this helps.
    Thanks,
    Tim

  • I’m frustrated
    ok, well. I tried a straight through cable with no success. So far I have been able to get the power on and HDMI input 1 to work as well as the mute toggle(thank you for that). I still can not get volume up or down to work. All of this buy the way is with a null cable and device code: Sony Receiver RS232(cable straight through device). I get nothing using the device that says use port 33335.

    ugh. so frustrating.

  • Hi Shane,
    What device are you using for your gateway? I know there is an issue with the GC-100 devices with RS232. If you send commands too quickly, it overflows the buffer and then nothing works for a while. I've gone back from using RS232 to control to just using it to grab feedback.

    I have no idea what the iTach's are like with RS232.

    I believe I am using a straight through cable from the GC100 to my Blu ray player (not using with a receiver), but that was so long ago now, details are fuzzy.

    I don't think you should need to worry about ports, I don't think iRule allowed you to change them on a GC-100/iTach, they are just built in with default ports.

    My only other suggestion is to give Docklight a try. Depending on your device, it may help to check the actual commands you are sending.

  • You need to change to the older Sony RS232 codes for volume up and down. If you search for a Sony RS232 AVR manual, you can find the full codes...

    Volume Up: \x02\x06\xA0\x52\x00\x02\x00\x01\x05

    Volume Down: \x02\x06\xA0\x52\x00\x02\xff\xff\x08
