ISSUE
- Cannot read barcode
- Scanned data does not come
APPLIES TO
PM5
RESOLUTION
If the scanner is activated but no data comes to the host device, check the PM5's status indication (LED and beep sequence) when you tried to read the barcode.
| Symptom | Cause | Solution | |
|---|---|---|---|
| Beep Sequence | LED Sequence | ||
| Twice (Short medium → High) | Red flash | Decoding failed | When the scanner failed to read the barcode, the beep rings twice (Short medium → High) and LED flashes red. Aim the barcode referring to the below instruction and try again. |
| Three times (3x Short low) | Red | Decoding success, but Bluetooth is not connected | This indicates the scanner succeeds in reading the barcode but is connected nowhere with Bluetooth. Find how to confirm whether the PM5 is connected. Bluetooth Disconnection
The connection may be lost if the host device and PM5 are about 10m or more apart.
If the host device is turned off or PM5 reboots accidentally (Battery discharges, etc.), the device and scanner will be disconnected.
Turning off the Bluetooth feature will disconnect the connection between the host device and scanner. |
| Once (Short high) | Green flash | Decoding success | You didn’t get the scan data even though reading the barcode is successful, perform reset the PM5 and try again. Refer to PM5 Reset (링크걸 FAQ 작성하기!) for more detail. |
