information
The
GPIO
port
allows
encoder
stop
/
start
control
and
TTL
voltage
output
for
monitoring
systems.
TTL
pin
behavior
by
default
is
HI
(3V)
when
encoding
and
LO
(0V)
when
not
encoding.
Logic
of
the
TTL
pin
can
be
configured
based
upon
video
detection,
encode
status,
and
manual
override
with
the
PP9
API
command.
Please
view
API
details
for
further
configuration
information.
The
DVC
Parport
allows
custom
events
to
be
programmed
upon
input
pin
voltage
change.
It
contains
4
available
inputs
for
custom
commands.
Please
contact
technical
support
for
advanced
usage
in
programming
the
parallel
port.
