Base Address
Before you install the coprocessor board in your system, its base I/O address must be set. The
base address may be set to any even value in the range 0000 to FFFE (hexadecimal) by means
of option shunts A1 through A15. These option shunts are factory set to locate the board at
address 02B2 and 02B3. To avoid conflicts, you must map the 417 into a two-port address
range that is unoccupied by other devices.
Option Shunt Table
If you require the 417 board to have a base address different from the default address , use the
following table to help to determine the proper shunt settings:
