Digital outputs on connector X4
Optocoupler output:
The transistor connections, collector and emitter, of the optocoupler output are galvanically isolated
from the Reader electronics and are carried to the outside without any internal ancillary circuitry on
Terminal X4. The output must therefore be powered by an external power supply.
