The safety interlock signal prevents the Master Controller from releasing the safety interlocks on all attached daughter boards. The safety interlock is only applicable to daughter boards that have laser controllers. Without the safety interlocks released, daughter boards are prevented from powering on lasers. The safety interlock signal floats high to 3.3V and must be pulled down to ground to release the interlocks. It must be pulled to ground with less than 1kΩ of impedance. This pin can be permanently shorted directly to ground if safety interlock functionality is not required. | The safety interlock signal prevents the Master Controller from releasing the safety interlocks on all attached daughter boards.
