Note that on some models, internal links have been factory set in order to allow power input via
the serial D25. In these instances power will either be on:
pins 8, 9: GND
pins 12,13: power in
in either case a grommet must be present in the normal power jack input to prevent a short in the
supply and protect against static discharge. Such models are supplied with the grommet fitted
and it should never be removed.
