verify your IP address and make sure that you recorded the Ethernet
address correctly. If the READY LED is blinking slowly, the
GPIB-ENET has an internal error. In this case, refer to Appendix C,
to determine which error is being reported
and contact National Instruments.
Troubleshooting EDVR Error Conditions
In some cases, calls to NI-488 functions or NI-488.2 routines may
return with the ERR bit set in
ibsta
and the value EDVR in
iberr
. The
value stored in
ibcntl
is useful in troubleshooting the error condition.
EDVR Error Condition with ibcntl Set to 0xE028002C (-534249428)
If a call is made with a board number that is within the range of allowed
board numbers (typically 0 to 3), but which has not been assigned to a
GPIB interface, an EDVR error condition occurs with
ibcntl
set to
0xE028002C. You can assign a board number to a GPIB interface by
configuring the GPIB software and selecting an interface name. For
information on how to configure the GPIB software, refer to
EDVR Error Condition with ibcntl Set to 0xE0140025 (-535560155)
If a call is made with a board number that is not within the range of
allowed board numbers (typically 0 to 3), an EDVR error condition
occurs with
ibcntl
set to 0xE0140025.
EDVR Error Condition with ibcntl Set to 0xE0140035 (-535560139)
If a call is made with a device name that is not listed in the logical
device templates that are part of the GPIB Configuration utility, an
EDVR error condition occurs with
ibcntl
set to 0xE0140035.
EDVR Error Conditions with ibcntl in the Range from 0xE1002710
(-520083696) to 0xE1002EE0 (-520081696)
These errors are returned from the WinSock Interface. The lower
16 bits of
ibcntl
specify the actual WinSock Interface error. For more
information about the specific error, refer to your WinSock Interface
documentation.
