Board Number Conflict

This section contains information specific to the Windows product.

Problem:

Keysight 488 calls are received by the wrong GPIB interface, causing unpredictable program behavior.

Probable Causes:

The same board number may be assigned to two different interfaces.

Suggested Steps:

Note that the board number (used in Keysight 488 function calls) is the numeric part of the VISA Interface ID. For example, if the VISA interface ID of your interface is GPIB1, its board number is 1.

Assign a unique board number/VISA interface ID to each GPIB interface in your test system, using Keysight Connection Expert or the configuration utility provided by your hardware vendor.

For example, if the board number 0 is in assigned to an National Instruments GPIB interface, do not use the VISA interface ID GPIB0 for a Keysight interface.

More Information:

Conflicts may occur between board numbers of different vendors' GPIB interfaces, particularly where these board numbers are set using different configuration tools (such as Keysight software for Keysight interfaces and NI-MAX for National Instruments interfaces). Connection Expert scans for conflicts when new interfaces are detected, and renumbers Keysight interfaces if necessary.

To change another vendor's board numbers, you must use that vendor's configuration utilities (for example, NI MAX).
