18.2.4 How to Connect a Barcode Reader
Since a barcode reader requires an additional 5 VDC, this voltage can be supplied either by an Interface
Expander (order number 75-5735-0003) or by an external power supply unit. The supply of power from an
external power supply unit requires a cable (order number 90-10040) into which the power supply can be
directly fed. If the voltage is to be supplied by an Interface Expander, then the barcode reader is connected
by the customer as follows:
Note the following pin assignment when connecting the cable:
