Notes for Establishing a Connection
z
Scanning a barcode
The scanner cannot read a barcode unless a connection has been established with the
communication unit. (Buzzer will sound.)
z
Using multiple BL-N90 scanners
• Only the connected scanner and communication unit pair can communicate with one
another.
• If multiple BL-N90 scanners read the same communication unit barcode, only the first
scanner to read the communication unit can communicate with it.
To change the pairing, follow the procedure below entitled "Swapping out the BL-N90".
z
Swapping out the BL-N90
When swapping one BL-N90 scanner for another, follow the procedure below.
Procedure
1
Hold down "Trigger" on the paired BL-N90 for about 10 seconds to enable sleep mode.
A beep will sound as sleep mode is enabled ( page 1-6).
During sleep mode, the wireless connection is disabled, causing the blue LED on the
communication unit to flash. This connection must be disabled in order for the communication
unit to pair with another BL-N90.
2
Use the second BL-N90 to scan the barcode of the communication unit.
3
Scan the initialization barcode ( page 2-15).
Note
If multiple BL-N90 units read the BD address barcode for the same communication
unit, you will not be able to determine which BL-N90 the communication unit will
establish a connection with.
Always combine the BL-N90 and the communication unit in a single pair.
