Troubleshooting
If your DAS-8 Series board is not operating properly, use the information
in this chapter to help you isolate the problem. If the problem appears
serious enough to require technical support, refer to Technical Support on
page 6-5 for information on how to contact an applications engineer.
If you encounter a problem with a DAS-8 Series board, use the
instructions in this section to isolate the cause of the problem before
calling Keithley for technical support.
Device initialization error messages
During device initialization, DriverLINX performs a thorough test of all
possible subsystems on the DAS-8 Series board as well as the computer
interface. If DriverLINX detects any problems or unexpected responses, it
reports an error message to help isolate the problem. The device
initialization error messages fall into three basic categories:
•
Device not found
— Board address does not match hardware setting
or conflicts with another board. Verify the board’s address settings.
Also, don’t confuse hexadecimal with decimal addresses in the
DriverLINX Device Configure dialog box.
•
Invalid IRQ level
or
Invalid DMA level
— Selected level does not
match hardware setting, conflicts with another board’s IRQ/DMA
levels, or is dedicated to the computer’s internal functions (COM port,
disk drive controller, network adapter, etc.)
•
Hardware does not match configuration
— Operating mode/range
switch or jumper setting does not match selection(s) made in the
DriverLINX Device Configuration dialog box.
