GPIB-410 User Manual
Base I/O Address Configuration
The GPIB-410 is addressed as an I/O port and decodes the lower ten
address lines of the PC I/O channel.
The base I/O address for the GPIB-410 is determined by the switches at
position U65 on the interface board. The switches are set at the factory
for the I/O port address 300 hex. This is used as the default base I/O
address value by the GPIB-410 software. The GPIB-410 occupies 32
contiguous bytes of I/O space. The base address of this 32-byte block of
addresses can be any multiple of 20 hex ranging from 000 hex to 3E0
hex (for example, a base address of 300 hex would occupy the addresses
300 to 31F hex on the interface board).
Note:
Check to see that this address is not already used by equipment
installed in the IBM Personal Computer. This address does not
conflict with any of the addresses listed as used or reserved in
the IBM Personal Computer Technical Reference Manual;
however, interfaces manufactured by companies other than IBM
may use this address.
