John,
A question came to mind as I read through some of Stan's comments and your response.
Does the RF key fob transmit continuously if you hold the button down?
The jumpers you described in this table might offer different options for use with either the key fob or direct inputs. For example, inputs held high could cause continuous play of a media file. The question there is, would the file repeat; say in the "100" option below (I note that it does NOT say "Play Once"). It also seems as though you could configure "001" to start and stop play of a media file?? Seems interesting.
Or am I totally misinterpreting? Tx.
