Chapter 2
Installation and Configuration
If the resources match the default settings, proceed to the Install the
GPIB-PCII/IIA section, later in this chapter.
If the resources do not match the default settings, you must reconfigure
the jumpers and switches, as described in the next few sections, to
match the resources assigned to the GPIB-PCII/IIA by Windows.
Configure the Input/Output Range (GPIB-PCII Mode)
An Input/Output Range is a segment of address space reserved for the
input and output of a board. The base I/O address of an Input/Output
Range is the first position in the Input/Output Range used by the plug-in
interface board. By default, the GPIB-PCII/IIA is configured to use
base I/O address 2B8 hex. With this setting, the board uses an
Input/Output Range of 2B8 hex to 2BF hex.
Follow these steps to reconfigure the base I/O address of the
GPIB-PCII/IIA.
1.
Locate the base I/O address switch at U2 on your GPIB-PCII/IIA
board. Refer to Figure 2-5.
2.
Change the switch settings to configure the GPIB-PCII/IIA board
to match the base I/O address of the Input/Output Range assigned
by Windows.
Press down on the side marked 1 to select a binary value of 1 for
the corresponding address bit. Press down on the 0 side of the
switch to select a binary value of 0. Refer to Figure 2-7 for
two examples of the switch settings and corresponding base I/O
addresses.
