m.I 2 of 5 optional Mod 10 Check Digit data error (if enabled)
n.Data Match Error (~BC).
o.Increment or Decrement data Error (~Br).
LED Operation
1.LED1 will turn on when Port 1 is active due to ISO, Symbol Contrast, X dimension, ratio, mod check or quiet zone error conditions.
2.LED1 will flash when Port 1 is active due to a data increment or decrement error condition.
3.LED2 will turn on when Port 2 is active due to a partial, % decode or no read error conditions.
4.LED2 will flash when Port 1 is active due to a Data Match error condition.
5.Flashing on indication will override a solid indication if both types of error conditions occur.
Note: Both LEDs can be on in cases where multiple bar codes are analyzed in a sync period.
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.
~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 ISO 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.
