Configuring the QSDI paddle board

Configuring the QSDI paddle board to work in a system consists of setting these option switches for each serial port:

Baud rate

Port address

DTE/DCE mode

The QSDI paddle board has fourteen option switches, SW2–13, SW15-16. Figure 158 on page 671 identifies the location of option switches on the QSDI paddle board. Learn how to set these switches in the following sections.

Once the board has been installed, the system software must be configured to recognize it. Instructions for doing this are found in the section titled “Software service changes” on page 679.

Option switch settings

Baud rate

Switches SW13, SW10, SW11, and SW12 determine the baud rate for ports 1, 2, 3, and 4, respectively. See the settings for these switches in Table 211.
