use typecast with the correct type (e.g. U16 or I16). The display setting is just cosmetic and has no influence on the underlying data.

Here's an example:

hey altenbach
thanks for the help
does this convert signed numbers whose ascii's are being generated into decimal??
i mean how are the signed numbers manipulated?
thanks

If you want signed numbers, make the diagram constant into I16 representation (right-click).

Numerics are internally always binary.  "decimal" for numeric indicators is just a cosmetic property. If you have a formatted string, you need to know the format it is supposed to be. If you have a binary string as in your example, you just need to know the correct datatype and you need to ensure that the byte count matches.
