Running ADAINST
After the jumpers and switch are set and the 1200 board is installed in ttre computer, you are ready to configure
SIGNAL*MATH so that it is compatible with your board's settings. This is done by running the ADAINST driver
installation program. After running the program, open ADA1200.EXE from the Open aFile menu. You will see a
screen similar to the screen shown in Figure D4 below. The factory default settings are shown in the illusration.
Your settings may or may not match the default settings, depending on whether you have made changes to these
settings before.
Base Address. The board's base address setting is entered in the upper right block, as shown in the diagram.
The factory setting for all Real Time Devices boards is 300 hex (768 decimal). The base address can be entered as a
decimal or hexadecimal value (hex values must be preceded by a dollar sign (for example, $300)). Refer to your
board's manual if you need help in determining the correct value to enter.
EOC IT (End-of-Convert Interrupt). In this block, enter the IRQ channel number which corresponds to your
jumper setting on P8.
Timer IT (Timer/Counter Interrupt). This block is not used on the 1200, and should be left blank.
LabTech Sw IT (LABTECH NOTEBOOK Software Interrupt). This sets the software intemrpt address
where LABTECH NOTEBOOK's labLINX driver is installed. The factory setting is $60. This setting can be
ignored when running SIGNAL*MATH.
