Parse VISA reference name

[Viper]

I have a multi channel test setup that uses a serial port for each channel. So I have named the VISA aliases for the channels to DUT-1 through DUT-8. I have a coaxial switch that routes an signal from the current DUT to a freq counter so that I can measure the frequency. The switch has eight positions that use an enum POS0, POS1, .... POS8. I need to translate the Serial port selected to the correct pole on the switch so I made the attached VI. The problem is that it works great when its open but doesn't when it is closed. What can I do to performe this function with a closed vi?

Try using "Type Cast" to convert the VISA refnum into a string, instead of the Text.Text property.

That did it. Thanks
