Personal488 User's Manual For Windows95 and Windows NT
Configuring the New Hardware
The following text will guide you through the setup of your IEEE 488 controller interface. It includes
instructions on how to verify the resource settings of ports in your system, and how to properly
configure the switches/jumpers on your interface board.
To avoid a configuration conflict, you must first verify which I/O addresses, IRQs, and DMAs are
being used by existing ports in your system, prior to configuring and installing the IEEE 488 controller
interface.
Step 1: Verifying/Recording the Current System Settings
The Windows
Control Panel
enables you to easily determine and configure the I/O addresses, IRQ
setting, and DMA settings in your system for proper operation. Perform the following steps to verify
your system settings.
1. Open the
Control Panel
window from the
Start > Settings
menu, click on the
System
icon, and
select the
Device Manager
tab. Under the line "Ports (COM & LPT)", look for a list of used ports.
For each port, highlight the port and click on the
Properties
button.
2. Properties already being used in the system are displayed under the
Resources
tab. Values NOT
listed are available.
•
For each listed port, record which Input/Output (I/O) address, if any, is being used.
•
For each listed port, record which Interrupt Request (IRQ) value, if any, is being used.
•
For each listed port, record which Direct Memory Access (DMA) value, if any, is being used.
3. Exit Windows and turn the system OFF.
The I/O base address, IRQ, and DMA settings are switch/jumper selectable via the following locations
on the GP488B interface board: One 8-microswitch DIP switch labelled SW1, two 12-pin headers
labelled J3 and J4, and one 3-pin header labelled J5. The DIP switch settings, and the arrangement of
the jumpers on the headers set the hardware configuration.
For the next steps, make sure that the I/O address, IRQ, and DMA, set on the interface board are
different from any existing ports in your system. A conflict results when two I/O addresses, IRQs, or
DMAs are the same. (As the exception, additional GP488B interfaces may share the same IRQ and
DMA values.) If there is a conflict, perform the following steps to select new switch/jumper settings.
