On Line Operating Mode
Figure 69 - On Line Mode Selection
This operating mode requires the reader to be connected to an external Presence Sensor
using EXT TRIG/PS A and EXT TRIG/PS B inputs.
During the active phase of the presence sensor, the DS6400 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 70 - 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, while the reading phase is
activated each time a barcode enters the reader 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.
