SV Commands Important for Mode 17
This system is operating in a “mode” rather than fully programmable logic. The port activation parameters
are programmable via the ~PB8 rather than ~PB1, ~PB2, etc. for each individual port. Other commands,
such as mode commands are also available. The commands most useful for this system application are
described below. Please see the SV 2 Series Operator’s Guide for additional command description details.
~LV17
This command sets this mode of operation.
~Lp0
This command turns off all partial decode logic at the decoder level
~Lp1
This command turns on partial decode logic at the decoder level
~LQ1
This command allows partial decodes to activate the output ports
~LQ0
This command disables partial decodes to activate output ports.
~LAxx
This command sets the passing threshold for the Overall ANSI method Symbol Grade. For example:
~LA28 causes an Overall Symbol Grade of 2.7 or lower calculated for the code analyzed to set a failure
condition for this parameter.
~LDxx
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.
~PP801xxx
This command sets the “active” time for the port pulses. The value “xxx” sets the time in .1 second
intervals. Any value greater than 100 (10 seconds) creates a latching output.
~PB816xxx100
This command sets the minimum percent of scans on a code which calculate good quiet zones to determine
an acceptable quiet zone analysis. The field xxx is the minimum passing threshold. Example: if xxx = 030,
a minimum of 30% of all fully decoded scans on a code must calculate a good quiet zone, or a failure
condition is set for this parameter.
~PB806xxx000
This command sets the threshold for the ANSI Defects calculation on a code to set a failure condition. The
field xxx is the passing threshold for the calculation. For example: if xxx = 025, a Defects analysis of 26%
or higher will cause a failure condition for this parameter.
~PB802xxx100
This command sets the threshold for the ANSI Decodability calculation on a code to set a failure condition.
The field xxx is the passing threshold for the calculation. For example: if xxx = 037, a Decodability
analysis of 36% or lower will cause a failure condition for this parameter.
~PB804xxx100
This command sets the threshold for the ANSI Symbol Contrast calculation on a code to set a failure
condition. The field xxx is the passing threshold for the calculation. For example: if xxx = 020, a Symbol
Contrast analysis of 19% or lower will cause a failure condition for this parameter.
