Mode 12 LED Operation
1. LED1 will turn on if Ports 1-4 go active due to ISO, contrast, or quiet zone
failure
2. LED2 will turn on if Ports 1-4 go active due to a partial or no read condition
Note: Both LEDs can be on in cases where multiple bar codes are analyzed in
a sync period.
SV Commands Important to Mode 12
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.
~LV12
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.
