MAINTENANCE, TROUBLESHOOTING & TECHNICAL SPECIFICATIONS
Possible Causes
RS-232 receive error.
The linear imager scanner is
buffering Code 39 data.
Or
Keyboard parameter selected.
Bluetooth disconnection event.
Code 39 buffer is full.
Low battery.
A transmission error was
detected in a scanned symbol.
The data is ignored.
The linear imager scanner is
either:
- Out of range
- Not paired to the cradle
- Not connected to a remote
Bluetooth device.
Acknowledgment that transmitted
data was not received by the
cradle.
Conversion or format error.
Communication with the bus was
not established.
Possible Solutions
Normal during host reset. Otherwise,
set the linear imager scanner's RS-232
parity to match the host setting.
Normal.
Or
Enter value using bar code keypad.
Move the linear imager scanner back
into range of the remote device.
In Master (SPP) mode, re-pair the
linear imager scanner and cradle by
scanning the PAIR bar code on the
cradle; check cradle power.
In Slave (SPP/HID) mode, reestablish
connection between the linear imager
scanner and remote device from the
remote device side.
Scan the Code 39 bar code without a
leading space or scan Do Not Buffer
Code 39 on Code 39 Buffering - Scan
& Store on page 11-32 to transmit
stored Code 29 data.
Place linear imager scanner in cradle
to charge the battery.
This occurs if a unit is not properly
configured. Check option setting.
Move the linear imager scanner back
into range of the remote device.
Or
Scan the PAIR bar code on the cradle.
Data may have been received by the
host. Check the host system for receipt
of transmitted data. If data was not
received by the host, re-scan the bar
code.
Check ADF rules for the host.
Communication with the bus must be
established before the linear imager
scanner can operate at the highest
power level.
