Note:
1. Trigger mode:
Single read: When a bar code has been decoded, the reader will be turned off. The
reader must be triggered again to read another label. It can be triggered via button,
serial port or auto trigger.
Continuous read: The reader will produce as much data as it can decode
regardless whether it is the same or not. This mode is mainly used for demonstration
and diagnosis.
2. Read mode:
Disable repeat read: Disable continue to read the same barcode.
Enable repeat read: Enable continue to read the same barcode.
Multiple read: The same label can only be decoded again after the label has not
been detected for a number of scans. This mode can only be programmed in
Continuous read trigger mode.
