Fig. 14 Switching Inputs
The switching inputs In1 up to In3 can be used for triggering or for connecting an encoder. All switching
inputs are identical. The used circuits have an internal electrical isolation. The inputs are galvanically isolated
from the GND and Laser on/off.
Each switching input has its own ground connection (Gnd-In1 to 3), which has to be connected with the
external ground (synchronization/trigger source or another device).
