USB Connection
USB is default interface for the Configuration Utility. Since no setup is required with USB, the
Setup button is grayed out.
COM (RS-232) Connection
When COM is selected, click the Setup button to open the dialog box as shown in Figure 9
(page 61). The following parameters configure how the computer running the Configuration Utility
communicates with the printer:
COM Port Select COM1 to COM30. The default is COM1.
Baud Rate Sets the baud rate of the serial interface. Baud rate is the speed at which
serial data is transferred between the host computer and the printer.
Choices are 1200, 2400, 4800, 9600 (default), 19200, 38400, 57600, or
115200.
Data Bits Select the serial data word length, 7 or 8 (default).
Parity Select None (default), Odd, or Even.
Stop Bit(s) The number of stop bits in the serial data word. Select 1 (default) or 2.
Flow Control Select None, Hardware (default), or Xon/Xoff.
When Xon/Xoff is selected, the printer controls the communication flow from
the host by turning the transmission on and off. In some situations, such as
when the buffer is full or the timing of signals is too slow or too fast, the printer
will tell the host to stop transmission by sending an XOFF character. The data
does not have any End of Text codes; Xon/Xoff is not a blocking protocol.
Note: The default settings for COM within Setup should match the printer factory default for
RS-232. Before modifying these settings, test the connection with the printer using the default
settings.
Ethernet Connection
When Ethernet is selected, no setup is required from the Tool Interface section. However,
Ethernet setup within the Interface Tab must be configured before communication can begin. See
Ethernet Connection for instructions on how connect to the network (page 80).
