Note Never delete the OMEGA ENGINEERING PowerDAQ
software from you PC directly. Always use Uninstall
program from PowerDAQ folder or Control
Panel/Add-Remove Programs applet.
Note Once the installation is complete, the PC must be
rebooted for the proper operation.
Note Windows NT/2000/XP users must be logged in as
an administrator or have equivalent access.
Base address, DMA, Interrupt settings
The PowerDAQ DIO boards are configured automatically by the PCI bus
on power up. You do not have to set any base address, DMA channels
or interrupt levels.
Although PowerDAQ DIO board may share interrupts
with other devices, for the faster response it is
important to have dedicated interrupt for the
PowerDAQ DIO board or at least share interrupt
between PowerDAQ DIO boards only. Sharing
interrupt with a slow devices such as USB or serial
ports or with mass-storage/network/video
controllers may reduce a performance, especially for
the high-speed IRQ/state change and/or streaming
applications. Usually you can easily change BIOS
interrupt allocation using the BIOS Setup program.
Please refer to your PC motherboard manual for the
details.
