Communication
Chapter 10:
Communication
The QC-300 can communicate with a computer over a standard RS-232 serial port and with printers over
the USB port.
Connecting to 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 serial 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: 9600
• 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.
