Anyone else using an Ipad to control their ADA?
How does the RS232 work?
The harmony remotes are 'ok' but once you get a 'proper' universal remote the difference is quite pronounced, especially in terms of responsiveness and customisation. You do have to put in more work of course.
If you want to use an iPad then go for it, personally the 1100 put me right off touch screen remotes as I like to be able to pick up the remote in one hand, in the dark and operate by feel and not have to a) Light up the room and b) put my wine down and have to use both my hands to alter the volume!
I bought Nevo Q50 which I love but if I was buying now I think Remote4 would be top of my list.
Going back to the iPad, there are many options but for RS232 you will need compatible hardware that can send RS232 codes to the ADA via the ADA Bus or IP. There is a spreadsheet of ADA codes available and I believe they are also in the manual.
All you need to do is program the buttons to send the specific codes. I had a half hour play with iRule and it was easy enough to setup and get going. There is a big thread in this forum on the iRule I believe if you want more info.
If you wish direct RS232 via the ADA bus then you need to get the wiring diagram for the ADA Bus so you can correctly connect the 3 RS232 wires to the correct connectors.
I bought a cheap RS232 cable and cut the plug off one end. To correctly wire it up (on the cable I had) I used the following wiring:
Ada Bus / RS232 Wire
1 / Yellow
2 / brown
3 / Red
4 DO NOT USE (+15V)
I can't remember the actual RS232 pin Numbers for the above wires but will try and dig them out as the above may not work for you.
Do not connect anything to Pin 4 on the ADA bus as it is a 15V power terminal and may cause damage to your RS232 device of the ADA.
Using this method is not supported and is done at owners risk! Don't come crying to me if you house burns down etc.
