102 Option settings
Address
Switch SW15 or SW16 and logic on the card always address the four
UARTsusing a pair of addresses: 0 and 1, 2 and 3 through 14 and 15. The
configurations for both switches are shown in Table42 "QSDI paddle board
address switch settings" (page 102). To avoid system problems, switches
SW15 and SW16 must not be configured identically.

* To enable ports 1 and 2, set SW15 position 1 to ON. To enable ports 3 and 4, set SW16 position 1
to ON.
+For each X, the setting for this switch makes no difference, because it is not used.
DTE/DCE mode
Each serial port can be configured to connect to a terminal (DTE equipment)
or a modem (DCE equipment). Instructions for configuring the DTE/DCE
switches SW2, SW3, SW4, SW5, SW6, SW7, SW8, and SW9 are shown in
Table43 "QSDI paddle board DTE/DCE mode switch settings" (page 103).
Example: Port 1 is changed from DTE to DCE by reversing every switch
position on SW3 and SW2; that is, switches that were off forDTE are turned
on for DCE, and switches that were on forDTE are tur ned off forDCE.
