GPIB-488
EABO—I/O operation aborted
Cause:
I/O operation aborted. (time-out)
Solution:
Check that the device is powered on.
Verify proper cable connections.
ENEB—Non-existent GPIB board
Cause:
GPIB board is not recognized.
Solution:
Make sure that GPIB board settings and configuration setup
parameters agree.
EOIP—Function not allowed while I/O is in progress
Cause:
An illegal call is made during an asynchronous I/O operation.
Solution:
Only
ibstop
,
ibwait
, and
ibonl
calls are allowed during
asynchronous I/O operations. The driver must be resynchronized by
calling one of the following:
•
ibwait
(mask contains
CMPL
)—The driver and
application are synchronized.
•
ibstop
—The asynchronous I/O is canceled, and the
driver and application are synchronized.
•
ibonl
—The asynchronous I/O is canceled, the interface
is reset, and the driver and application are synchronized.
Re-synchronization is successful if a CMPL is returned to
ibsta
.
ECAP—No capability for operation
Cause:
A call attempts to use a capability which is not supported by the
GPIB board.
Solution:
Don't use the call.
