13. Peripheral Devices
13.1 Activation of a Serial Interface RS 232
Your Cash Register can be equipped with up to 6 interfaces.
Location of interfaces (rear view)
Each of the interfaces can be used after the activation. However, you may choose any in-
terface for a peripheral device once it has been activated. You may program the Identifica-
tion Number of the peripheral devices to be used. Note that the interface RS 485 is re-
served for a Cash Register network. For the Scanner use only the interface named
SCANNER because this connector is equipped with the separate power supply (5 +) for
the Scanner.
13.2 Cables
The pin-layout of the serial ports of the QUORION cash registers is the same as the pin-
layout of a serial port of a computer.
13.2.1 PC-Cable
For the connection between a Cash Register and a PC (QProg) you need a standard 9-
pin cross wired computer cable which has all signals connected.
