But a word of warning is in order here. Direct writes to the addresses simply by reference to the
base address of the PCI-DAS1602/16 I/O registers is not advised. Since the addressess assigned
by the PCI plug & play software are not under your control, there is no way to guarantee that
your program will run in any other computer.
Not only that, but if you install another PCI board in a computer after the PCI-DAS1602/16
addresses have been assigned, those addresses may be moved by the plug & play software when
the second board is installed. It is best to use a library such as Universal Library or a program
such as HP-VEE to make measurements with your PCI-DAS1602/16.
3.4 Testing The Installation
After you have run the install program and set your address and interrupt with InstaCal, it is time
to test the installation. The following section describes the InstaCal procedure to test that your
board is properly installed. The procedure has you connect one of the outout channels to one of
the A/D channels, it then outputs a simple waveform and shows you the wavefrom monitored on
the selected A/D channel.
1. With InstaCal running, select the PCI-DAS1602/16.
2. Select the "TEST" function from the main menu
3. Follow the instructions provided
If you do not receive the expected results:
a. make certain you have connected the correct pins according to the connector diagram.
b. go back through the installation procedure and make sure you have installed the
board acording to the instructions.
If this does not get you to the desired display, please call us (or contact your local distributer) for
additional assistance.
3.5 Calibration
Selecting CALIBRATE from the InstaCal main menu runs a fully automated PCI-DAS1602/16
calibration program. The software controlled calibration of the PCI-DAS1602/16 is explained
extensively in the section on calibration.
