~H#nn
Sets the number of signal transitions to search for finding a bar code symbol
nn= values of 10 through 99. This indicates the number of high to low transitions of the optical signal to search before ending a search for a bar code. High values of nn are useful when complex graphic fields or small fonts are closely adjacent to a bar code and therefore in the scan path. The higher the number, however, the greater chance the analysis rate will be lowered. For normal situations with minimum graphics in the same path as the bar code, a value of 10 is recommended (~H#10.)
Label Setup Commands – L
A ‘~’ followed by an ‘L’ specifies a command from the Label Setup category. The next character identifies the particular Label Setup Command. In general, the commands in this category terminate with one or more numeric digits. The Label Setup Commands are listed below.
~LA##
Overall passing grade.
##is the numeric grade value – 00 through 40. Example ~LA32 causes an ISO Overall Symbol Grade of 3.1 or lower to set a failure condition.
~LC##
Minimum number of symbol characters to decode in an Interleaved 2 of 5 symbol.
This command sets the minimum number of symbol characters to be expected (## in the command,
Note: Each I 2 of 5 symbol character contains two data digits, therefore the symbol in the example must contain a minimum of six data digits to be decoded.
~LD##
Passing percent decode.
This command sets the % decode threshold for a passing condition. If analyzing poorly printed symbols, it is recommended that partial decodes be enabled at the decoder level when this command is enabled.
xx= failure threshold. Example ~LD75: if 74 % or less of scans on a code were not fully decoded, this sets a failure for this parameter.
