Configuring The New Hardware - Omega OMB-PER-488/W95 User Manual

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.

Note:
There is only one revision level of the GP488B/MM board which is currently supported by 32-bit
Driver488 software, Revision B. Consequently, only GP488B/MM Revision B is discussed in this
manual.

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.
(1) GP488B/MM is only compatible with the Ampro PC/104. (2) Only GP488B/MM
Revision B is discussed in this manual. (3) Microswitches 6, 7, and 8 on switch SW1 do not
have a function on this board.
