~LN##
Set Minimum Number of Bar Codes Per Label (i.e., per sync period)
This command instructs the verifier on how many bar codes it is expected to read
and analyze during a sync period. If the programmed number of codes are not
read, a (robust) NO READ condition is internally flagged for communications or
output port activation. Except for mode ~LV03, this command sets the minimum
bar codes expected. Mode ~LV03 uses this value for the EXACT number of
codes read during the sync interval.
Note: See ~LZ##
## = 01 through 99
Default = 01.
~LN and ~LZ commands can be entered via bar codes to eliminate the need for a
PC to program No Read conditions
a. Bar codes embedded with a ~LN or ~LZ command can be entered by
placing the bar code in the beam at any distance or angle where the
READ led is on, then going through the same procedure as the calibra-
tion procedure.
b. The settings are stored in temporary memory, therefore a power up will
revert back to original settings in permanent memory.
c. Unlike the calibration procedure, the laser beam will not turn off after the
command is scanned, but, like the calibration procedure, the CAL LED
will turn off.
d. The format for the bar code command is;
1. Code 39
2. Data "RJSLxnn" where x is N or Z and nn is the 2 digit number in the
command. Example: RJSLN02 sets the ~LN02 command in
temporary memory.
3. Ratio and X dimension can be any value that can be scanned by the
SV unit.
~LP#
Set Sync Polarity (See
ities.)
# =
0 Falling edge of signal is active
1 Rising edge of signal is active
