~LN##

This command sets the minimum number of codes to be read during a sync period. ## = the number of codes. For example: ~LN02 causes a No Read condition to be set if less than 2 bar codes are fully decoded during a sync interval. See the ~LZ## (page 6-17) command below for priority.

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 18 (~LV18)

I/O operation

1.System will operate Envelope or Edge sync mode (~LX#)

2.Sync polarity – programmable (~LP#)

3.Use ~PR0210 for proper port initialization.

4.Port 1 will go active OFF (no current) on an error condition.

5.Port 2 will go active ON (sink current) on an error condition.

6.Port 3 will operate in per analysis pulse mode. Active polarity ON (sink current), approximately 500 millisecond duration. Port 3 will activate (pulse) on an error condition.

7.Port 4 will operate in per analysis pulse mode. Active polarity ON (sink current), approximately 50 millisecond duration. Port 4 will activate (pulse) on an error condition.

8.Port 5 will pulse active ON for an acceptable condition (absence of error condition.)

9.Port 5 pulse time programmable (~PP801xxx). Pulses will act like a re- triggerable 1-shot.

10.Pushing the reset button or power re-cycle will place Ports 1- 5 in their inactive states.
