I need to send the code to get the projector powered up. I tried repeating the code, but it does not work. THe IR appears to have a repeat, so I am not sure how to handle it. Here is the code....
0000 006D 0001 0011 0140 00A1 0014 003D 0014 003D 0014 0014 0014 0014 0014 003D 0014 003D 0014 003D 0014 0014 0014 003D 0014 003D 0014 003D 0014 0014 0014 003D 0014 0014 0014 0014 0014 0014 0014 02EB

All I did is "learn" the code from the original remote and press the on button for about 2 seconds ion order to turn the SX21 on or off.

It needs to be in a macro, so my projector goes on with the all on sequence. I have found some posts about how to copy and repeat the code, but I cannot seem to find one that talks about if the code has a repeat in it. Thanks.

See your point. I had the same problem and because I (nor anyone else for that matter) could not find a solution on how to include the "press for more than 2 seconds" in a macro, I just decided to design a seperate button for the on/off function. Not as fancy, but it works. I still have the question outstanding with JVC to provide me with the (extended) discrete code

I have been working with athaler and have finished a program that will take a standard learned code, and repeat the the "repeat burst" string, adjusting the header so that it will be of any time duration you want.

Unfortunately the Philips people also made sure that would not work. There are some maximums associated with how many bytes long an IR pattern can be. My testing indicates about 510 values or 255 burst pairs. For athalers case that was about 0.6 seconds, not very long.

I am very suspicious of the issue with the holding the key down. Has any one ever verified with an oscope that the same pattern just keeps coming out and not something special.

I did not verify anything. Too technical for me. I'll post my IR code this evening, i.e. the code my button uses. And all I do is keep the button pressed for about 2 secs.

as promised, the ir codes I use for on:
0000 006D 0001 0011 0140 00A1 0014 003D 0014 003D 0014 0014 0014 0014 0014 003D 0014 003D 0014 003D 0014 0014 0014 003D 0014 003D 0014 003D 0014 0014 0014 003D 0014 0014 0014 0014 0014 0014 0014 02EB

and the one for off:
0000 006C 0007 0011 0016 003B 0016 0013 0016 003B 0016 0013 0016 0013 0016 0013 0016 02F3 0016 003B 0016 003B 0016 0013 0016 0013 0016 003B 0016 003B 0016 003B 0016 0013 0016 003B 0016 003B 0016 003B 0016 0013 0016 003B 0016 0013 0016 0013 0016 0013 0016 02F3

All I do is press the button for about 2 seconds and it switches on or off

Hi
Discreet On Off codes are available, together with input selection, I think they are on one of the JVCPRO sites.

thx 49thnorth for adding this to the thread. Unfortunately, when I searched their database, I couldn't find the sx21u. Which may make sense because their database was updated somewhere in 2002. Might find some other handy codes in there though. Still hoping that johnsattuck remembers where he saw the codes.

I've never tried this, but can't you put a leaned IR code in the middle of a Macro, as well as button links? I only use aliases, but it looks like you could elarn the code and put it in the macro list just the same as if it was the only item in the list. But, as I say, I haven't tried it myself!

BTW, have you tried the following discretes? They are listed as being for JVC projectors, but no model numbers....

Power Off
0000 006d 0010 0011 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 003c 0014 003c 0014 0014 0014 0014 0014 003c 0014 003c 0014 003c 0014 0014 0014 0014 0014 003c 0014 003c 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 02e6



Power On
0000 006d 0010 0011 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 003c 0014 003c 0014 0014 0014 0014 0014 003c 0014 003c 0014 003c 0014 0014 0014 003c 0014 0014 0014 003c 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 02e6

49th north, I wanted to thank you for telling us about the IR pages on the premise site. It didn't fix my problem, but it did give me more codes to try. It is good info to have. Now saved as a favorite.

Thanks,
Mark

All,

Finally found a discrete code that does work:
0000 006d 0010 0011 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 003c 0014 003c 0014 0014 0014 0014 0014 003c 0014 003c 0014 003c 0014 0014 0014 003c 0014 0014 0014 003c 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 02e6
Now I only need to press it once and the sx21 turns on. Strangely enough I did find this one in the pronto forum. Now I have another problem. According to the thread in the pronto forum, the discrete for off is:
0000 006d 0010 0011 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 003c 0014 003c 0014 0014 0014 0014 0014 003c 0014 003c 0014 003c 0014 0014 0014 0014 0014 003c 0014 003c 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 02e6
This one however doesn't work at all. Is there someone outthere who can help (Barry?) figure out the correct code for off based on the ones mentioned? I also would like to include it in a macro (to accomodate the mrs....) :-}
