~LS##
Set minimum number of scans for valid read
## = 02 – 99 (See ~SBn command for ##=01; single scan mode)
This command sets the minimum number of times a full decode must be achieved on a symbol in order to
be a valid read. The system acts slightly differently, depending on what operation mode is set – ~HO1 or
~HO2.
With ~HO1 enabled, if the minimum number of full decodes is not accomplished, a No Read condition is
set, even though the bar code is read, analyzed and reported. The report includes a No read status
indication. With ~HO2 enabled, if the minimum number of full decodes is not accomplished, the code is
not recognized nor reported. This essentially creates a No Read condition when a sync input is being
received.
When used in conjunction with the ~LDxx command, the ~LS## command can create a powerful area
check of a symbol.

~LV##
Output Interface Mode
## =
00 - 99:
This command sets the output interface mode of the unit. Modes have fixed port activation logic defined by
specific applications. Some activation parameters are programmable. Custom modes are available – contact
PRINTRONIX technical Support. Modes included in standard SV 2 Series are described in the Output
Interface Modes Descriptions Section. Example: ~LV01 sets mode 01.
~LX#
Sync Type
0 - Envelope sync
1 - Edge sync
2 - Envelope sync w/beam control – leading edge turns on laser, trailing edge turns off laser
Note: ~LP# sets polarity for Modes 2, 19 and 20 when ~LX2 is set
3 – Edge sync w/beam control – edge turns on beam, bar code exiting beam turns beam off
Note: Use ~LS02 setting for sync type ~LX3
~LZ##
Set Exact Number of Codes per Label (i.e., per sync period)
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 can also be entered by scanning a bar code. See details in the ~LN
command description.
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.
~Lp#
Turn partials on and off at the decoder level for all symbologies.
