Before testing WaveBook, make sure the device has been properly installed and powered-on. Make sure
the parallel port cable is firmly in place on both the WaveBook and the proper LPT port in the computer.
When testing WaveBook, if the unit does not respond within 30 seconds perform the
following steps:
1) reboot the system
2) upon power-up, re-open the Daq Configuration applet
3) select another configuration setting
4) reinitiate the test
To test the currently stored configuration for the WaveBook device, click the Test button. Results should be
displayed in a few seconds. The test results have two components: Resource Tests and Performance Tests.
Resource Tests. The resource tests are intended to test system capability for the current device
configuration. Resource tests are pass/fail. Test failure may indicate a lack of availability of the resource,
or a possible resource conflict.
Base Address Test. This resource test checks the base address for the selected parallel port. Failure of
this test may indicate that the parallel port is not properly configured within the system. See relevant
operating system and computer manufacturer’s documentation to correct the problem.
