The driving logic of the input signals may be powered, for convenience, with the voltage
supply at the CBX terminal block spring clamps (V+) and (V-). In this case, however, the
device is no longer electrically isolated. The voltage available on pins V+ and V-, is physically
the same as the input power for the scanner (Vdc and GND).
