9 CAM interface
A galvanically-isolated, bi-directional interface is provided for communication with a CAM system�
en
Four commands each can be received from the extraction unit and four status notifications transmitted to
the CAM system via two input signals and two output signals�

9.1.1 Outputs (Out1 / Out2)
The output signals are executed as potential-free switch outputs of
an opto-coupler with a series resistance of 150 Ohm�
For maximum pull-up voltage (U) and maximum permissible
switching current (I), see Chap� 8 Technical data�
The pull-up resistance (R) must be dimensioned in such a way
that the maximum permissible switching current is not exceeded�
9.1.2 Inputs (In1 / In2)
The input signals are transferred to the LEDs of opto-couplers� For the required input voltages of the two
signal levels "low" / "high", see Chap� 8 Technical data�
