Configuring the SDI paddle board

Configuring the SDI paddle board consists of setting these option switches for each serial port:

•Port address

•Baud rate

•DTE/DCE/Fiber mode

The SDI paddle board has seven option switches, SW 2–8. Figure 156 on page 664 identifies the location of option switches on the SDI paddle board. Instructions for setting these switches are in the section that follows.

Once the board has been installed, the system software must be configured to recognize it. Instructions for doing this are found in “Software service changes” on page 665”.
