Input Timer
Timer which is triggered by another source. Typically used to
coordinate multiple Readers scanning the same package.
DeviceNet Input
Up to 7 discrete DeviceNet inputs trigger decoding. Refer to
Configuring DeviceNet Inputs on page 9–15.
[Package]
The same trigger configured for package is also used to trigger
decoding. See page 11–13.
[Message]
The same trigger configured for messages is also used to trigger
decoding. See page 10–5.
[Match Table]
The same trigger configured for match table is also used to trigger
decoding. See page 11–8.
[Decoder]
The same trigger configured for decoding on another Reader is also
used to trigger decoding on the current Reader.
The capture count specifies the number of consecutive identical valid
decodes before a valid read occurs.
If Capture Count is 3 or less, Scan is Valid
If Capture Count is 4 or more Scan is not Valid
Scan 2

Use higher capture counts to reduce misreads. Symbologies that are
not self-checking (do not use start and stop characters or check
characters) are more susceptible to misreads.
Setting the capture count too high may result in excessive no-reads,
particularly when the number of scans crossing the label during a
trigger period is low (5-10). Set the capture count to a value no
greater than half the number of scans crossing the label during a
single trigger period.
