FORMAT MASK
This function conditions the CLV to transmit only specified characters of a read bar code, providing a way to mask the bar code
data transmission to the host device and rearrange the sequence of the data set if required. The user can select up to 35 charac-
ter positions of a bar code to be transmitted to the host device. Each position can contain up to 2 digits with a numeric value of 0
to 90. Special characters include “--”, “ZZ”, and “OO”. The “--” character is the continuation character, meaning from x to x. The
“ZZ” character places a “0” in the output string and the “OO” character in the first position disables the format mask function or
terminates the condition at the character position entered.
For example, if only the last five positions of a 10-digit bar code are to be transmitted in the sequence they appear in the bar
code label, the first five positions of the Format Mask section would contain 6, 7, 8, 9, 10. The CLV would then only transmit the
sixth, seventh, eighth, ninth and tenth positions/characters of the bar code label.
Note: In the “Reading Diagnostics” mode on the terminal interface line, the bar code data is displayed in its original form. In the
“Monitor Host” mode, the data output is displayed as defined by the Format Mask function.
