1. Write down the AT E Series board serial number in the AT E Series
Hardware and Software Configuration Form in Appendix D at the
back of this manual. You will need this serial number when you
install and configure your software.
2. Turn off and unplug your computer.
3. Remove the top cover or access port to the I/O channel.
4. Remove the expansion slot cover on the back panel of the
computer.
5. Insert the AT E Series board into an EISA or 16-bit ISA slot. It
may be a tight fit, but do not force the board into place.
6. Screw the mounting bracket of the AT E Series board to the back
panel rail of the computer.
7. Check the installation.
8. Replace the cover.
9. Plug in and turn on your computer.
The AT E Series board is installed. You are now ready to install and
configure your software.
Board Configuration
Due to the DAQ-PnP features, the AT E Series boards are completely
software configurable. Two types of configuration must be performed
on the AT E Series boards—bus-related configuration and data
acquisition-related configuration. Bus-related configuration includes
setting the base I/O address, DMA channels, and interrupt channels.
Data acquisition-related configuration, explained in the next chapter,
includes such settings as analog input polarity and range, analog output
reference source, and other settings. For more information about data
acquisition-related configuration, refer to your NI-DAQ user manual.
Bus Interface
The AT E Series boards work in either a Plug and Play mode or a
switchless mode. These modes dictate how the base I/O address, DMA
channels, and interrupt channels are determined and assigned to the
board.
