IO_OUTP_CTRL 1-4
The
outputs
(Output
mode,
Polarity)
are
controlled
via
4
advanced
feature
registers
(see
90).
The
Polarity
field
determines
whether
the
output
is
inverted
or
not.
The
output
mode
can
be
viewed
in
the
table
below.
The
current
status
of
the
output
can
be
queried
and
set
via
the
PinState.
It
is
possible
to
read
back
the
status
of
an
output
pin
regardless
of
the
output
mode.
This
allows
for
example
the
host
computer
to
determine
if
the
camera
is
busy
by
simply
polling
the
BUSY
output.
Note
Outputs
in
Direct
Mode:
For
correct
functionality
the
Polarity
should
always
be
set
to
0
(SmartView:
Trig/IO
tab,
Invert=No).
