Alan, you lost me with the ... What can happen w these rf processors.
R u referring to the crestron module or the marantz? Gman said the flasher stayed on so the flaw was in the crestron control no?
One problem with RF UIs--TPMC 3,4,8x, MTX3, ML600--is that the processor often receives the press but misses the release. In any system both are required or how else would the processor know when to bring that signal low.
It sounded as if your problem might be the result of the processor seeing the signal going high ( button press ) but not going low ( processor not seeing the release. ). In Real Time this is seen as button press and release. In debugger it is seen by high and low. In logic it's the rising edge and falling edge.
Glad to hear you solved your problem with a simple driver change.
If the processor sees the press the signal goes high and remains high till it sees the release. So for a button press driving an IR driver the flasher will go high and stay high as long till the button release is "seen" by the processor. If it already was generated but missed by the processor due to god knows what in RF transmissions you end up with this sort of situation where the volume just ramps for ever.
