I have an unusual situation.
i have about 16 devices and about 6 of them behave strange. not sure how to fix them any one have suggest me a direction please.
when I scan UPC-A bar-code, it transmit only last 11 character leaving very first char out.
but in data wedge profile it show as decoder param for UPC-A is set as Preamble none.
i could change this to Preamble Sys char. and save it.
but when i go back to run Velocity it scan only the 11 character.
when I come back to data wedge profile, it changed back to "preamble none" by itself.
i try several way, to delete the profile and create new profile and it behave same way.
i deleted the profile, and when i start velocity it create the profile with none option.
if I set as with "sys char" then it changes back to none again.
not sure why it doing it.
