Table 3-1. Selecting the Address with DIP Switch S1
Switch Position Serial Port Address (Hexadecimal)
1 238 to 23F*
2 2B8 to 2BF*
3 338 to 33F*
4 3B8 to 3BF*
5 278 to 27F*
6 2F8 to 2FF (COM2:)
7 378 to 37F*
8 3F8 to 3FF (COM1:)
*These addresses are not supported by DOS, but can be
supported by special software. Be very careful if you select
the address 278 to 27F or 378 to 37F: These are normally
parallel-port (LPT2: and LPT1:) addresses, and if a printer
or any other device is plugged into a parallel port on the
same PC, there could be a conflict.
