Address
Switch SW15 or SW16 and logic on the card always address the fourUARTsusing a pair of addresses: 0 and 1, 2 and 3 through 14 and 15. Thesettings for both switches are shown in Table323 "NT8D41BA addressswitch settings" (page 827). To avoidsystem problems, switches SW15 andSW16 must not be configured identically. Figure 270 "NT8D41BA QSDIpaddle board" (page 823) displays SW15 and SW16.
