NI MAX VISA Alias Question...

[ChristopherPovey]

Got an issue:

I have hooked up two USB I2C boards to a PXI rig. The two items have appeared in NI MAX with their serial numbers. I rename their VISA aliases to "I2C" and "IC2_ST".

Sometime later one of them stops working.

I replace the broken one for a new one.

NI MAX shows the new device.

I try to rename the new I2C VISA alias to "I2C", but NI MAX errors because the "I2C" is already allocated.

I cannot remove "I2C" without plugging in the old board (which is broken in this scenario). so how do I remove the "I2C" alias without plug in the board?

I am await of the "Reset Configuration Data", but this will reset all the aliases. There must be a better way?

NI MAX version 5.3.1

Thanks.

I have MAX 14.5 so it might be a little different.

In MAX:

Tools -> NI-VISA -> VISA Options
In general settings select Aliases
Select the Alias you want to clear
right click -> Clear Alias

You can then give this alias to the new board.
