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.
