   Would it be ok to use the SX28 and enable the sleep mode and have the alarm event wake up the SX and then enable the transmitter by pulling the power down pin high, then send sync pulse followed by a loop containing the identifier data string that tells the BS2 which transmitter is active so that it can activate the proper alarm input on the sensaphone. Also should there be a reset based on time so that the alarm if triggered it will reset its self and return to sleep mode. I have been trying to find some examples of appropriate sync pulse code for the SX28. Also should the internal clock be used or a external oscillator? Thanks David[/2]
