Can someone who knows about this please help...
I am trying to control an old JVC FM tuner via its compulink-1
connection.
I have read that the codes sent via compulink are the same as the
remote control codes. I have programmed the remote protocol (well,
the only one I could find) into WinLIRC and am transmitting it as 5v
pulses to the tuner.
It does nothing.
I have measured the output on the compulink connections when the tuner
is operated on a digital scope. It only transmits one code - when any
preset is selected. The pulse timings of these pulses are an order of
10 longer than the remote pulse timings I have found online, which
broadly agree with each other.
So I tried the remote codes with the longer timings, it still does
nothing.
I've tried MSB first, LSB first, positive going, negative going...
What am I doing wrong??
Thanks for any help you can give,
Alex
