6.5 Serial interface COM (RS232)

The serial interface is used for digital data transmission. The RS232 interface can be connected by
using a commercially available 9-pin SUB-D cable.

Information:

Pin 9 of the serial interface connector can be used for additional connection
of a 5V power supply, e.g. for operating a serial barcode scanner. The COM
+5V switch in the service slot of the device must be put in the ON position in
order to use this function. A subsequent restart of the computer may be
required in order to properly activate this function.
