Communication
Chapter 9:
Communication
The QC-330 communicates with computers over the RS-232 serial port and with printers over the USB
port.
Connecting to a computer
1 Verify that the QC-330 and computer power are off.
2 Connect a computer COM port to the QC-330 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-330.
The default QC-330 settings for communication over the
RS-232 serial port are shown here.
• Baud rate: 2400
• Parity: None
• Data bits: 8
• Stop bits: 1
• EOC Delay: 0
• EOL Delay: 0
Current settings for your QC-330 are shown on the Ports setup screen discussed in detail in Chapter 10:
Setup.
4 Launch the computer application that will be used to communicate with the QC-330, and configure the
communication properties of the COM port to match those of the QC-330.
