Note: The DTR input is
used to put the radio
into sleep mode. The
radio sleep option must
be enabled first using
the configuration
software. Once
enabled, lowering the
DTR signal will put the
radio in sleep mode
and raising the DTR
signal will put the radio
in idle mode, ready to
receive or transmit
data.
