Good Decode Reads

Note When setting up, determine if the scanner's scan rate is capable of scanning
:
your longest symbol the required number of times.
Decodes Before Output
Definition: The number of decodes (from 1 to 31) required per symbol before a
symbol's decoded data is sent. It requires the scanner to successfully
decode a symbol a designated number of times before it is sent. If it
doesn't achieve the number of good reads during the read cycle, then a
noread will be sent.
Note: Higher settings will decrease throughput speed.
Usage: This is a very useful feature to increase reliability of reads for symbolo-
gies that do not have internal error checking such as Pharmacode.
Serial Cmd: <K221, decodes before
Default: 1
Options: 1 to 255
Consecutive Status
Definition: When consecutive is enabled, the number set in Decodes Before Out-
put must be achieved consecutively before decoded data is sent.
When the default non-consecutive is set, whenever a cumulative num-
ber of decodes is achieved, decoded data is sent. For example, if non-
consecutive is enabled and Decodes Before Output is set to 10, then
data will be sent when the total number of decodes reaches 10 regard-
less of the number of bad reads between decodes.
Usage: Useful when the highest level of reliability is required.
Serial Cmd: <K221, decodes before
Default: Non-consecutive
Options: 0 = Non-consecutive
1 = Consecutive
