Device Initialization Error Messages
During device initialization, DriverLINX performs a thorough test of all
possible subsystems on PIO-SSR boards 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 Configuration 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.
Problem Isolation
If you encounter a problem with a PIO-SSR Series board, use the
instructions in this section to isolate the cause of the problem before
calling Keithley for technical support.
Identifying Symptoms and Possible Causes
Table 7-1 lists general symptoms and possible solutions for problems with
PIO-SSR Series boards. Use the troubleshooting information in Table 7-1
to try to isolate the problem.
