Isolation between the command logic and the scanner is maintained by powering the inputs
with a different supply voltage (Vext) from that supplied on the Aux. Interface/Input Signal
A and B connectors (VS).
The driving logic of the input signals may be powered, for convenience, with the voltage
supply between pins A2 (VS) and A1 (GND) of the connector. In this case, however, the
device is no longer electrically isolated.
The electrical features of these inputs are:
