Storage
When the distance between the scan gun and the receiver is too far or environmental
interference, the transmission will fail, then, wireless scanner automatically stores
scanned bar codes. After communication restored, according to the FIFO principle, the
gun automatically send stored barcodes. When the bar code sending fails, for storage,
the buzzer sounded, "Didi" twice to prompt.
There are two reasons for the failure of bar code sending, one is that the distance
between the wireless scanning gun and the receiver is greater than the effective distance,
the other is subject to interference from other wireless device signals. Solutions:
