Fig. 17 Options to switch off the laser
Use a serial key switch inside the control circuit to switch off the laser.
If the voltages between pin 3 and pin 1 are < 0.8 V, the laser is off. No external resistor is necessary to the current limitation. Connect
pin 1 with 2 and pin 3 with 9 for permanent laser on.
The external laser switching-off is implemented as a hardware solution and is a top priority. The laser can be switched off, in addition,
also by software.
