Applies To:

Versions Affected:

Surface mount style brain boards 9159, 9159A, 9159B

Symptoms:

Surface mount style B6 brain boards may exhibit intermittent operation after a Pamux bus reset command is sent from the computer.

Workaround:

Add a 10 ms delay in software after a Pamux bus reset.

Example:

Using any Pamux toolkit, the following example code shows how to open a handle to the B6 with the PCI-AC51, and where to add a 10 ms delay for the surface mount style B6 to work consistently:

For adapter cards such as an AC28 that does not use a communication handle, simply add a 10 ms delay after any instance of a Pamux bus reset.
