We strongly recommend that users install PWM+/- signal to a relay output port
in series (Set it to PWM+/- enable signal.), then access to the laser, which can avoid
laser light leakage in modulation mode. Please refer to “2.5 Laser Connection” for
more details. Furthermore, please adjust PWM signal level. 24 V or 5 V level can be
selected through dip switch.
2.3 Terminal Instructions
2.3.1 External power source
External power source provide direct current 24 V for BCL3766 External IO Board. 24
V and COM of power input terminal are connected to 24 V and 0V of power output
interface, respectively.
2.3.2 Servo control interface
The four servo control interfaces on BCL3766 are DB15 two-row bores, and pin
definition is as below:
8 7 6 5 4 3 2 1
15 14 13 12 11 10 9
