89 North LDI-6 Operating Manual page 26

Light will not emit from the system until Run mode is selected. If 'External Digital' mode is selected for
shutter control, verify that the shutters indicated as Open correspond to the desired channels.
Click the ON button in the upper right corner of the GUI to put the system in Run mode. When the system
is in Run mode, laser light will emit from channels with Open shutters and intensities greater than 0%.
NOTE:
If 'Host USB' mode is selected for shutter control, to turn a channel off, click the corresponding shutter
button to turn it to "Shutter Closed". If 'External Digital' mode is selected for shutter control, to turn a
channel off, set the corresponding TTL input voltage to the Shutter Closed TTL level.
To turn all channels off, click the OFF button in the upper right corner of the GUI to put the system in Idle
mode.
At any point, depressing and releasing the soft power button on the LDI front panel will remove power
from all lasers. Alternatively, selecting 'System Reset' from the 'System Info' tab of the 'System Info &
Settings' window will also remove power from all lasers and restart the system, as if the soft power button
was toggled (Figure 21).

Attempting to operate more than 4 channels simultaneously could lead to
performance degradation and/or over-temperature conditions. Operation of more
than 4 laser lines simultaneously is not a supported operating mode.
The LDI will not produce light until commanded into the Run mode. The System
Indicator icon in the upper right corner of the GUI will display the IEC laser radiation
warning symbol when the system is in Run mode.
