Zusammenfassung:An apparatus and module for use with a vending machine (10) using an optical communication data exchange standard. An optical transceiver (32, 34), such as an IrDA TM compatible transceiver, is mounted on a printed circuit board (50) adjacent to a customer display (28). An isolator (52) is mounted between the IR transceiver (32, 34) and the customer display (28) such that the IR transceiver's (32, 34) performance is not degraded as a result of noise emissions originating from the customer display (28).
