2.4.2 Connection to PC
The QMP 5000 can be connected to a PC for programming, reporting and back-office. QUORiON
offers a small software tool, called QProg, for this purpose. The connection can be established via
RS232, USB or LAN.
Connection via RS232
By default RS232 port 1 is prepared for PC communication with 57600 baud. Please note that you
will probably need an adapter cable from the RJ45 connector of the QMP 5000 to DSUB-9 on PC
(see chapter 2.4.4). If your PC does not have an RS232 port, you may use a Serial-to-USB
converter.
For the RS232 connection you need a standard 9-pin cross wired cable with female DSUB
connectors which have all signals connected.

Connection via USB
If you want to use USB, you need to install a driver on your PC first. This driver will create a virtual
COM port in your Windows system. Please follow these steps to install:
• Switch on the QMP 5000
• Connect the cash register to the PC using a standard USB device cable
• Wait for the Windows message “New hardware found”
• Select the driver files “stmcdc.inf” and “usbser.sys” from your local drive
• The installation will now run automatically
Please note, that system parameter 1 in the cash register (PC port) has to be re-programmed to 16
for USB communication. This will activate the USB communication, but de-activate RS232 for PC.
The communication between PC and QMP 5000 will run with 12 MBit/s (USB full speed).
