TTL modulation
In the
modulate mode the output power can be switched between two levels by
applying a
compatible (
0 V
and
5 V
) external control voltage. The lower level is set by
the
PO=
command and the higher level by
P=
. If a level larger than the maximum output
power is specified for
P=
or a level larger than the
P=
value is specified for
PO=
, the value
is decreased to the maximum value.

Status and device information
The query
S?
gets the actual status of the laser system including information about the
Enable Request, the key switch, the interlock, active errors and the temperature control.
The query
R?
returns the operation hours of the laser system. The operation time is
the accumulated time during which the laser was active (red LED on).
