MC33 Android 7.0 Datawedge Escape as a Suffix

I need for a MC33 in Datawedge as a Suffix a Escape (HEX: 1B).

In the basic formatting, i´v entered in Keystroke output in "Suffix to Data" /x1B. When i scan now a Barcode for example 123 i got the result 123/x1B. I´v checked also the "send as HEX" Setting, with the same result.

I can´t find as described in other Discussions the "allow Escapes in Pre/Suffix" Option in the Datawedge 6.6.50
