6 ) The serial port or the Ethernet interface sends a shutter opening
command to output the laser, and sends a shutter closing command to
turn off the laser.
Shutdown the laser, please refer to [4.9 Closing operation sequence].
4.8.3 External control mode (sequentially connected to 4.6)
Modulation: When the duty cycle of the laser's internal frequency is
set to 100%, the laser works in external modulation mode. The on and off
of the laser is controlled by the "modulation" signal provided by the user
from the external MOD interface. For the timing diagram, see [4.8.5
Control timing Figure];
Gate mode ：When the duty cycle of the internal frequency of the
laser is set to less than 100%, the laser works in internal modulation mode.
The laser is turned on and off by the user from the external MOD signal
and internal frequency generator. Stop internal pulse generation, see [4.8.5
Control Timing Diagram] for timing diagram;
The laser works in external modulation mode by default after power
on.
1) Turn on the air switch and the panel "power" indicator light is on;
2) Wait for 20s, internal main control board circuit initialization is
completed;
3) Set laser power (laser power is set by 0- 10V analog when AD mode is
enabled, laser power is set by serial port or Ethernet when AD mode is
off);
4) Send a light enable signal to the laser in one of the following ways
● Interface gives light enabling signal (connect 24V between PIN 18 and
PIN 20)
