MS-860 Industrial Raster Reader User’s Manual
Decodes Before Output
Note
:
When setting up, determine if the reader’s scan speed is capable of scanning
your longest symbol the required number of times.
Decodes Before Output Mode
Number Before Output
Usage:
Useful when the highest level of reliability is required.
Definition:
When consecutive is enabled, the number set in
Decodes Before Out-
put must be achieved consecutively before decoded data is sent. For
example, if
Number Before Output is set to 5, then the data will be
output whenever five decodes occur in succession.
When the default non-consecutive is set, whenever a cumulative number
of decodes is achieved, decoded data is sent. For example, if non-consec-
utive is enabled and
Decodes Before Output is set to 10, then data will
be sent when the total number of decodes reaches 10 regardless of the
number of bad reads between decodes.

Default:
Non-consecutive
Options:
0 = Non-consecutive
1 = Consecutive
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.
Definition:
The number of decodes required per symbol before a symbol’s decoded
data is sent. It requires the reader to successfully decode a symbol a des-
ignated number of times before it is sent. If it doesn’t achieve the num-
ber of good reads during the read cycle, then a noread will be sent.
Note: Higher settings will decrease throughput speed.
