AX10445 Module Series User's Manual
2.2 DIP S witches (Base Address
Selection)
The AX10445 interface module is controlled through the I/O
port. The I/O port base addresses are selected via DIP
switches. To help you locate the DIP switches (on this board
there are two DIP switches for Channel #1 and Channel #2
respectively), refer to the location diagram in Appendix A
and Appendix B.
The valid I/O port base addresses range from hex 200 to hex
3F8. Within this range you may specify your base addresses.
However it is not allowed to have two or more devices with
the same base address. Usually the I/O port base address is
set to the standard serial communication port COM1 (3F8 –
3FF) and COM2 (2F8 – 2FF). The following table illustrates
the base addresses and corresponding switch settings.
