quick hex string help

[g_e_m_i_n_i]

I know this should be very easy (or I assume it should be), but here is my question: 

On the block diagram side, how would I convert the string so that it gets into the proper hex format, so when my string is 0907 in hex, my light will turn on. Basically, I cannot seem to format the string to a 0907 from the weird symbol that it is now. I know it has to do with how the string is stored, as a "normal string" vs "hex string", but could someone show me how to switch between the two on the block diagram side easily? (on the VI side its as simple as a right click, but I was having troubles finding it).

Thanks - and have a good weekend all.

Your string is actually two characters \09 which is tab and \07.

Your case structure string should be "\09\07" which will get converted to "\t\07"
