Resource Tests
The resource tests are intended to test system capability for the current device
configuration. These tests are pass/fail. Resource test failure may indicate a lack of
availability of the resource or a possible resource conflict.
Base Address Test - Tests 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.
Interrupt Level Test - Tests the ability of the parallel port to generate interrupts.
Failure of this test may indicate that the parallel port may be currently unable to
generate the necessary hardware interrupt.
Note: Other parallel port devices may work fine in this mode. Some parallel port
devices (such as printers) do not require interrupts to work properly. See
relevant operating system and computer manufacturer’s documentation to
correct the problem.

Performance Tests
Performance tests check various DaqBoard functions with the current device
configuration. These tests give quantitative results for each supported functional
group. The results represent maximum rates at which the various operations can be
performed. Note that the rates depend on selected parallel port protocol and will
vary according to port hardware capabilities.
ADC FIFO Input Speed - Tests the maximum rate at which data can be transferred
from the DaqBoard’s internal ADC FIFO to computer memory, through the PC’s
parallel port. Results are given in samples/second, where a sample (2 bytes in
length) represents a single A/D value.
Digital I/O Input Speed - Tests the maximum rate at which DIO input data can be
transferred from DaqBoard’s Digital I/O ports to computer memory, through the
PC’s parallel port. Results are given in bytes/second.
Digital I/O Output Speed – Tests the maximum rate at which DIO output data can be
transferred from the computer’s memory to DaqBoard’s Digital I/O ports, through
the PC’s parallel port. Results are given in bytes/second.
