Setting I/O Addresses and DIP Switches (ISA Only)
Setting I/O
Addresses and DIP
Switches (ISA Only) This discussion concerns ISA adapters only. This driver supports only one ISA
adapter. When you install an ISA adapter, you must set the base I/O address in
two places
• In the driver software
• On the adapter itself, using a block of DIP switches.
Software I/O
Address During installation, the software base I/O address is set to default values by the
Add/Remove Hardware Wizard.
After you finish the software installation, you can use the Device Properties
Resources tab to view or change the Input/Output Range resource setting. If the
default values prove incorrect:
1. Select the Input/Output Range from the Resource Type list.
2. Select the Change Setting button.
3. You may need to choose a hardware configuration from the Setting Based On
drop-down list box to activate the Edit Input/Output Range widow.
Note: The I/O range setting is based on your hardware configuration setting. You
can have multiple hardware configuration settings, and this control may be
locked in some configurations.
Hardware I/O
Address The hardware base I/O address is set using a block of DIP switches on the adapter
circuit board. See your
Hardware Installation documentation for instructions on
how to set the DIP switches.
The software and hardware I/O address settings must match each other. For
example, if you set the DIP switches to 180 (hex), you must select 180 (hex) in the
software.
