# Generate Pairing Barcode for Datalogic Bluetooth scanners

## If a hand scanner has lost the connection to the base station or a new hand scanner should be paired with the base station, the pairing can be done by following these instructions:

1. Identify the COM-port of the scanner (either with rusty configuration or device manager)
2. Stop MetriX Rusty Devices to free COM port of the scanner
3. Use HTERM to connect to scanners COM port and obtain the scanners bluetooth address 
     1. In HTERMs input control, choose “CR-LF” for “Send on Enter”
     2. Send *$!* -\> The base station should respond with an identification and serial number.
     3. Send *$S* to enter service mode
     4. Send *$EU092* -\> The base station should answer with its 12-digit bluetooth address
     5. Send *$s* to exit service mode
4. In some cases the approach with HTERM can return a BT address that is obviously incorrect. In these cases, you need to install the software Datalogic Aladdin. 
     1. Connect to the base station (make sure to deactivate the MetriX devices service, otherwise Aladdin won’t find the base station)
     2. Open Terminal (lower right)
     3. Send *$EU092* (do not send $S / $s, that’s not needed in Aladdin)
5. Restart MetriX Rusty Devices
6. Use [https://barcode.tec-it.com/en/?data=%5C%3CFNC3%3ELnkCxxxxxxxxxxxx](https://barcode.tec-it.com/en/?data=%5C%3CFNC3%3ELnkCxxxxxxxxxxxx)to create a pairing barcode 
     1. The code has the format Code-128 and the syntax is \\\<FNC3\>LnkC{12-digit BT address} 
            1. *FNC3* is a Code-128 specific control sign
            2. *LnkC* is a string literal
     2. Replace the xxxxxxxxxxx in the link above with the bluetooth address
     3. Download the barcode
7. Send the pairing code to the customer
8. When the code is scanned, the handheld device should be automatically paired with the base station
