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.
