Mode 18 (~Lv18) - Hand Held Products SV Series User Manual

~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. See the
If the value ## = 00 (and ~LZ00 is also set), a sync input is disregarded, therefore
a No Read condition is disabled.
~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.
~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.

5. Port 2 will go active ON (sink current) on an error condition.
6. Port 3 will operate in per analysis pulse mode. Active polarity ON (sink
current), approximately 500 millisecond duration. Port 3 will activate (pulse)
on an error condition.
7. Port 4 will operate in per analysis pulse mode. Active polarity ON (sink
current), approximately 50 millisecond duration. Port 4 will activate (pulse)
on an error condition.
8. Port 5 will pulse active ON for an acceptable condition (absence of error
condition.)
9. Port 5 pulse time programmable (~PP801xxx). Pulses will act like a re-
