Make
sure
to
bring
the
lasers
to
correct
operating
mode
via
control
software
to
enable
external
digital
or
analogue
modulation.
If
LuxX
lasers
are
built
‐
in
the
LightHUB®
ULTRA
system,
the
digital
modulation
input
is
routed
to
the
laser
enable
input
of
the
LuxX
laser.
As
the
digital
modulation
input
is
pulled
to
ground
level,
the
LuxX
lasers
do
not
emit
laser
light,
even
when
switched
to
CW
operation.
Therefore,
a
digital
overwrite
is
available.
Use
the
digital
input
button
on
the
controller
level
to
deactivate
the
digital
input
globally
for
all
lasers.
Alternatively,
if
the
LightHUB®
ULTRA
housing
is
open,
push
the
button
on
the
Main
PCB
to
toggle
between
digital
input
active
and
not
active.
3.4 Description of CDRH-mode
It
is
possible
to
operate
the
LightHUB®
ULTRA
in
a
CDRH
compliant
mode.
The
main
controller
manages
CDRH
functionality.
No
external
CDRH
‐
kit
is
necessary,
as
the
LightHUB®
ULTRA
is
equipped
with
a
key
‐
switch
on
the
front
panel.
If
CDRH
‐
mode
is
needed,
activation
is
possible
via
“?CDRH”
command.
Refer
to
command
list
or
programmers
guide
for
further
assistance.
CDRH
features
If
the
key
switch
is
turned
into
OFF
position,
laser
emission
is
not
allowed.
Thus,
the
main
controller
of
the
LightHUB®
ULTRA
system
sets
all
lasers
into
interlock
state,
so
that
internal
laser
diode
energy
source
is
turned
OFF.
Laser
ON
commands
from
the
PC
to
the
lasers
directly
are
ignored
in
this
case.
The
laser
cannot
be
turned
ON
while
the
key
switch
is
in
OFF
position.
If
the
key
switch
is
turned
ON,
the
main
controller
starts
all
available
laser
systems
step
by
step.
Emission
from
the
first
started
laser
is
delayed
3
seconds
for
CDRH
compliance.
At
start
‐
up
or
reset,
CDRH
requires
a
key
switch
toggle
to
confirm
laser
operation.
The
key
switch
toggle
request
is
indicated
by
a
blinking
laser
emission
LED,
if
the
key
switch
was
in
ON
position
during
start
‐
up
or
reset
of
the
laser
system.
