Installation
Jumper’s setting on PDIUSBD12 ISA bridging board
The PDIUSBD12 ISA bridging board is plugged inside the device PC. It will occupy I/O, IRQ and DMA
resources of the device PC. To avoid possible conflicts in settings, we suggest removal of all the
unnecessary cards from the device PC. Sound card and network card may cause conflict in IRQ and
DMA setting.
Switch S1 sets the base I/O address for the D12 evaluation board. Default base address is 0x368.
The D12 evaluation board occupies 8 I/O locations. A0 to A2 are decoded on the D12 evaluation
board. Switch S1 sets the address decoding of A3 to A9. Please notice that a switch ‘ON’ is logic ‘0’.
