D
button. This allows full remote operation of the logger.
Do not connect permanently, or excess current will be
drawn.
Pin 6
Plug Detect
This pin when shorted to the ground pin, will allow the
microprocessor to know that a plug is connected to the
D and hence force the D to
‘listen’ at regular intervals for user commands. This can
be permanently connected to the ground, but the
lowest current consumption and hence longest battery
life is achieved by removing the communication lead
and hence disconnecting this from ground.
