8 QC-300 Series User’s Guide
Connecting a printer
The QC-300 supports certain USB printers. Printer models
must be specified by Metronics when the QC-300 is ordered, or
approved by Metronics later.
1 Verify that the QC-300 and printer power are off. Connect the
USB printer to the USB Type A port on the side of the enclosure.
2 Make sure the USB cable plug is fully inserted.
Connecting a computer
1 Verify that the QC-300 and computer power are off.
2 Connect a computer COM port to the QC-300 RS-232 se-
rial port using a standard straight-through serial cable (Metronics
part number 11B12176). Make sure the cable connectors are
tight, but do not overtighten the connector screws.
3 Apply power to the computer, and then the QC-300. The
default QC-300 settings for communication over the
RS-232 serial port are shown here.
• Baud rate: 1200
• Parity: None
• Data bits: 7
• Stop bits: 1
• Flow control: Hardware
4 Launch the computer application that will be used to communicate with the QC-300, and configure the
communication properties of the COM port to match those of the QC-300.
