Communication
Chapter 9:
Communication
The QC-300 can communicate with a computer over the RS232 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: 1200
• Parity: None
• Data bits: 7
• Stop bits: 1
• EOC Delay: 0
• EOL Delay: 0
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.
