3-22 Setup and Installation
4. Insert the BNC connector side first, pushing the BNCs through the
slot at the back of the computer. Bring the opposite side down into
the card edge guide. The lower left side of the board has a slight
bevel to facilitate insertion.
5. Push the board's connector strip into the expansion slot. Make sure
that the board is firmly placed into the bus.
6. Secure the board to the computer at the board's back bracket with the
cover plate screw. Some computer chassis and motherboards are
made with very loose dimension tolerances. Make sure when you
tighten the screw, the left side of the gold edge connector on the
DAS-4301/8K does not pull up and out of the expansion slot.
7. Once the board is firmly in place, attach the signal and trigger
connections to the BNC connectors at the back of the board.
Initializing the Board
To initialize the DAS-4301/8K board, locate the AUTO4300.EXE file on
the disk. AUTO4300 should be included in the AUTOEXEC.BAT file of
the root directory if the board is plugged into the bus.
AUTO4300.EXE initializes the DAS-4301/8K during power-up since the
board's setup parameters are random when the computer is powered on.
In some cases, the random analog offset and gain values could cause an
undesirable current drain in the analog section. AUTO4300.EXE prevents
this drain from occurring.
If you are using the default base I/O address setting of 250h, no
parameters are required. Include the following command line in the
AUTOEXEC.BAT file:
AUTO4300
If you are using some other base I/O address, include the base I/O address
(in hexadecimal notation) on the command line. For example, if you are
using a base I/O address of 258h, include the following command in the
AUTOEXEC.BAT file:
AUTO4300 258
If you are using multiple boards, you must initialize each board separately
because each board must use a different base I/O address.
