HandHeld Entertainment SV Series manual Mode 02 ~LV02, Mode 02 I/O operation

~PB802xxx100

This command sets the threshold for the ISO 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 ISO 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.

~LN##

This command sets the minimum number of codes to be read during a sync period. ## = the number of codes. For example: ~LN02 causes a No Read condition to be set if less than 2 bar codes are fully decoded during a sync interval.

~LZ##

This command sets the exact number of codes to be read during a sync period.

##= the number of codes. For example: ~LZ02 causes a No Read condition to be set if exactly 2 bar codes are not fully decoded during a sync interval.

This command overrides the ~LN## command if the number of codes set does not = 00. If ~LZ## is set to ~LZ00, the ~LN## command takes precedence.

~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.

~Hx

This command stores all parameters into non-volatile memory. This command should be the last command sent after parameters are programmed via the above commands.

Mode 02 (~LV02)

Mode 02 I/O operation

1.Envelope type sync input on pin 4

2.Port 3: per sync type. The state of this output must be stable within 12.5 milliseconds after the sync input goes low (trailing edge.) Typical time for stability will be less than 7.5 milliseconds if the sync is received when a bar code or complex graphic is not in the beam. The port shall go active (sink current) for the following conditions;

a.ISO Defects grade programmable (~PB806xxx000)

b.ISO Decodability grade programmable (~PB802xxx100)
