NOTE:
Both
the
input
and
the
output
are
electrically
isolated
from
the
rest
of
the
camera’s
electrical
circuitry
via
general
‐
purpose
photo
couplers.
The
input
is
additionally
protected
with
a
serial
250
Ohm
resistor
and
a
debouncing
circuit.
Duration
of
any
input
signal
should
be
at
least
5ms
to
comply
with
the
requirements
of
the
debouncing
circuit.
