5) I/O connection of digital signal: the supply current of input signals are less than 10mA, and
the supply current of output signals are less than 3 mA. The connection circuit of input and
output signals is shown in Figure 6.
Figure 6. Schematic of input and output signals.
6) The control board and laser driver can be powered separately. When there is failure in 24V
control board power supply, the laser will stop emission after 20 ms. When there is failure in
24V laser driver power supply, the laser will stop emission after 4 ms.
