Operating Modes
23
Stop Priority
It defines the parameter defining the end of the reading phase:
Selections:
Input/Serial Stop
the Stop Input or Serial Stop String define the end of the reading phase.
Timeout has a lower priority.
Always Timeout
the reading phase always stops when the selected timeout expires.
Start Input From Fieldbus
This parameter is available only when using a Fieldbus interface through the TCNM-ACBB5 connection box.
If checked, it allows the Fieldbus Master to remotely start/stop the reading phase via bit 7 (MSb) in Byte 0 (LSB) of
the Output Area.
Quality Counters
When checked, the Quality Counters parameter activates a counter handled event, which counts the good decodes
during the reading phase. If no stop reading phase event occurs, the reading phase is stopped at 100 good decodes.
This parameter is independent from the Decoding Safety parameter.
The value reached by the counter is transmitted in a fixed 3-digit format in the Info Field.
For Multilabel Code Combinations the counter increments for each good decode on each label in the reading phase.
Quality counters are not valid for code Reconstruction Reading Mode or for readers in a Synchronized network (Master
or Slaves).
Automatic
The device does not require connections with external presence sensors in this operating mode.
In this mode the scanner is continuously scanning. The reading phase is enabled when a barcode enters the reading
zone of the scanner and is terminated after an N number of scans without a code, where N is set using the Automatic
Threshold selection. The next reading phase will begin when a code enters the reading zone of the scanner again.
The N number of scans without a code must be selected to assure code identification in the reading zone.
Code transmission is identical to the other operating modes except that there is no transmission on the serial port in
the case of a No Read condition.
For details about the conditions to use this operating mode see the Operating Mode Reference Table.
Automatic Threshold
The Automatic Threshold sets an N number of scans without a code in order to assure code identification in the reading
zone.
Selection: a value from
10
to
32765
Code Filter Depth
In Automatic mode, Code Filter Depth is used to avoid multiple reads of the same code. The selected value (other than
zero) defines the number of codes to memorize in a FIFO list.
When a code is read, it is compared to the list. The application program inherently compares codes based on content
and code length. If the list contains a code identical to the current code being read, the current code is discarded. If
not, the current code is accepted and added to the list in the first position; the remaining codes in the list are shifted.
If the list is full the oldest code in the list will be flushed.
When = 0, there is no FIFO list and there is no filtering.
Selection: a value from
0
to
127
