~LL
Report the Excluded Symbologies and the Included Symbologies Specified for all the Defined Bar
Codes.
1)
Hexadecimal value ‘4’ - identifies the beginning of the datapacket response
2)
The mode for each symbology is reported in a character string, which terminated with either ‘IN’ (for
included) or ‘EX’ (for excluded) followed by a ‘\r’ character (carriage return) and a ‘\n’ character (a
line feed). See the example below. The next two columns indicate statuses of the ~LM and ~LN
commands respectively. (The ~LM command is not used in normal operation.)
3)
Hexadecimal value ‘5’ - identifies the end of the datapacket response
4)
L - the last character of the sent command string
Example return using ScanVision:
1- UPC/EAN- IN
2- C39- IN
3- C128- IN
4- CITF- IN
5- C93- IN
6- CBAR- IN
min chars: 032
number bc: 099
L
~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 is 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## command for other options.
## = 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 calibration 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 “PRINTRONIXLxnn” where x is N or Z and nn is the 2 digit number in the
command. Example: PRINTRONIXLN02 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 Sync Inputs Section for examples of sync input polarities.)
# =
0 (falling edge of signal is active)
1 (rising edge of signal is active)
