On Line Operating Mode
Figure 85 - On Line Mode Selection
This operating mode causes the reader to be connected to an external Presence Sensor
using I1A and I1B (External Trigger/PS) inputs.
During the active phase of the presence sensor, the DS8100A reader tries to acquire and
correctly decode the code.
In case the decoding phase is successful, the barcode characters are transmitted on the
serial interface. Otherwise, a no read message is sent.
Automatic Operating Mode
Figure 86 - Automatic Mode Selection
This operating mode does not require the connection to an external Presence Sensor.
When working in this mode the reader is continuously scanning. The reading phase is
activated each time a barcode enters the reading zone. The reader stops reading after an N
number of scans without a code. Barcode characters are transmitted on the serial interface.
In case of a failed reading phase no message is sent to the host computer.
