You must use shield wiring with the AC42, particularly for the card reader:
● Connect the drain wire (bare metal) from the reader cable bundle to the drain wire in the shielded
cabling. Then, connect the drain wire at the other end of the shielded cabling to Earth ground.
● Improper grounding and shielding may result in unintended product behavior.
It is recommend to connect one of the chassis grounding screws to the building ground at the
installation site.
