Mode 20 (~Lv20) - Hand Held Products SV Series User Manual

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.

Mode 20 (~LV20)

This mode is identical to Mode 19 with the exception the sync polarity is
reversed. The leading edge is low going.
