Setting the Address
The base address of the PIOC is set using a eight-position DIP switch, SW1. The eight positions correspond to the I/O address lines of A2 through A9 (see Table 2). If you set the a switch OFF the corresponding I/O address line will be a ZERO and if you set it ON the corresponding I/O address line will be a ONE. The factory default address setting is 378h. To set the card to the 378h address you must set A2 and 7 OFF and A3, 4, 5, 6, 8, and 9 ON. Table 3 shows the settings for LPT1 and LPT2.
