PIN 7-9 of the DB25 control interface is applied to 24V (enable hardware
emission);
Send the start or stop emitting command (enable hardware emission) to control the
emission by the PC software;
9) The laser is controlled by the user's "modulation" signal provided by the external MOD
interface
See 4.8 to get the process of laser shutting down.
4.7.4 AD mode
When PIN 7-9 of the DB25 control interface is applied to 24V, the laser enters the external
AD mode, and the power of the laser is controlled by the voltage obtained by PIN 22-25 of the
DB25 interface connector (1V-10% power, 10V-100% power).
When PIN 7-9 of the DB25 control interface is applied to 0V or left floating, the power of
the laser is set by serial port or Ethernet.
