Note: Both LEDs can be on in cases where multiple bar codes are analyzed in
a sync period.
SV Commands Important to Mode 01
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.
~LV01
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.
Note: In SV firmware versions x238 and lower, ~LQ commands are not
implemented and the command ~HQ1 must be used to disable partial
decodes from activating ports. In this case the standard data
transmission format is modified, and ScanView will not display data
characters correctly.
~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.
~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 ISO 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.
