Output 1 Parameters
Trend Analysis Mode
Usage: Useful in cases in which the user doesn't want to shut down for one con-
dition but wants to monitor quality and read conditions.
Definition: Sets the trend condition (Mismatch, Noread, or Reads/Trigger) that
will activate the output.
Parameters associated with Trend Analysis Mode are Number To Out-
put On and Trigger Evaluation Period. The Number To Output On
setting allows the user to select the number of times that the selected
trend condition occurs before activating the output. Trigger Evaluation
Period sets the number of triggered events to evaluate for trend condi-
tion.
Example:
Trend analysis mode = Noread
Number to Output On =4
Trigger Evaluation Period=25
In this example, the scanner will activate the output when 4 noreads
occur within a period of 25 trigger events (read cycles).

Default:
Noread
Mismatch
Definition: Output will be activated when the number of Mismatches equals the
value entered for Number to Output On within the trigger window
selected in Trigger Evaluation Period.
Noread
Definition: The output will be activated when the number of noreads equals the
value entered for Number to Output On within the trigger window
selected in Trigger Evaluation Period.
Decodes per Trigger
Definition: Monitors the number of good reads per triggered read cycle. If the num-
ber of decodes per trigger falls below the value entered in Decodes per
Trigger, a trend condition is set. If this trend condition matches the
number set in Number to Output On, the output will be activated.
