JVC VCR 008 power not working in macro

[shouyi]

Hi:

I'm working on a 15-1994 remote to get a simple working to turn on and off JVC 770 VCR. I tried to download the several codes online and none work. So I learned some code and created a device with Protocol name as "JVC" and device doe "83". In turn, Protocol ID is "00 34", fixed data is "35". In device code, I made power button discrete power on, and sleep button discrete power off.

Everything seems to worked except when I try to do a simple macro to turn on the power for VCR on the VCR device button. The macro is "M_VCR;C_CVR;T_VCR;P_TV;O_VCR;POWER". I also created an all off macro "O_VCR;SLEEP;AUX1;SLEEP;TV;SLEEP". This one don't work either. Power and sleep button works is I press them normally in VCR device mode. Sleep responds very quickly, but power sometimes fails to respond. I noticed that if I press and hold power button for a second or two, it works better.

I am using extender 5. What can I do to make everything work?

Thanks for any help you can give me. I hope I have provide enough information.

PS: Single info for learned commands all have two protocols, one called "JVC", the other "JVC{2}". All other information are the same.

I'm by no means an extender expert, but I do know that you're supposed to use the pseudo device buttons (ie, the ones that start with things like O_ ) in macros to select the device modes. The original device buttons are meaningless for remotes running extenders, the only reason they continue to select the correct device mode is because you've programmed a macro on them that selects the correct mode.

Therefore, you should re-think your second macro (ie, replace the AUX1 and TV steps) ...

"O_VCR;SLEEP;AUX1;SLEEP;TV;SLEEP".

Thank you Rob for taking the time answering my question. You are right that I should have replaced AUX1 with O_AUX1 and so on. And I did program AUX1 and TV device macros with pseudo device buttons.

But the funny thing is, the parts that was not efficient and potentially none-functional, worked; the part that's correct, didnot work.

I think at one point I did started with the original RDF without extenders and played with only the VCR device code. Still the same result.

It sounds like a similar issue as the one discussed in this thread:
How best to adjust JVC signal duration?

Turn out I have an old JVC device code worked just fine with a device combiner protocol I created. It was a combination of VCR, TV and receiver. Problem is, I changed the receiver; and more importantly, using this device combiner protocol, I needed 100 more bytes of device memory, which I don't have.

Hope the other protocols will allow me to save some of these memory.

Thanks again for the help.
