~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## (page 6-17) 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 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#
