~PB815xxx000
This command sets the threshold for the ratio calculation on a code to set a failure condition. The field xxx
is the passing threshold for the calculation. For example: if xxx = 025, a ratio analysis of 2.4 or lower will
cause a failure condition for this parameter.
~PB811xxxyyy
This command sets the threshold for acceptable X dimension ranges. The value for xxx is the narrowest
acceptable X dimension. The value yyy is the widest acceptable X dimension. Units are in .001 inch (mils).
For example: ~PB811010020 will cause a failure for an X dimension less than 10 mils or greater than 20
mils.
~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## 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)
A.
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.
11.
Error conditions available are:
a.
Partial Read (Programmable,
( ~Lp#, LQ#)
b.
% decode (Programmable,
~LD##)
c.
Bad Quiet Zone: < 10X
(~PB816xxx100)
d.
ANSI Defects grade (Programmable,
~PB806xxx000)
e.
ANSI Decodability grade (Programmable,
~PB802xxx100)
