Output Code Sorting
With this function, the user can determine whether the scanner will send the bar code data from one reading gate according to
the spatial position of the bar code labels (“code position”), the chronological appearance of the codes (“time backward” or
“time”), or code length.
Code Length
“Code Length” refers to the ability to scan several bar codes of different lengths and yet provide a constant data string to the
host. The CLV transmits the data string of multiple labels to the host device sorted by code length. The order in which they are
sent is determined by the code length values entered into the code length list. If the scanner scans more codes than entered in
the list, only the codes of the code length list are transmitted. The value for “Max. No. Codes” is no longer relevant. Identical code
lengths may be entered into the code length list and sorting is based on time decoded. If there is no matching code for a code
length value in this list, the appropriate position is replaced with the error string if the error string is activated. If the programmed
error string is longer than code length the defect string is truncated. If the programmed error string is shorter than the code
length, the last character of the error string is repeated (see example):
