Parameter Broadcast (Cradle Host Only)
When in multipoint-to-point mode, enable Parameter Broadcast to broadcast all parameter bar codes scanned to all other scanners
in the piconet. If disabled, parameter bar codes are processed by the individual scanner only, and the scanner ignores parameters
broadcast from other scanners or from the cradle.
Pairing
Pairing is the process by which a scanner initiates communication with a cradle. If the Multipoint-to-Point is scanned, multi scanner
to cradle operation is activated and up to three scanners can be paired to one cradle. The cradle includes a pairing bar code.
To pair the scanner with the cradle, scan the pairing bar code on the cradle. A high/low/high/low beep sequence indicates that the
pairing bar code was decoded. When a connection between the cradle and scanner is established, a low/high beep sounds.
1. The pairing bar code that connects the scanner to a cradle is unique to each cradle.
2. Do not scan data or parameters until pairing completes.
3. When the scanner is paired to the cradle in SPP Master, HID Master or Cradle Host mode, the scanner
automatically tries to reconnect to a remote device when a disconnection occurs that is due to the radio losing
communication. For more information see Auto-reconnect Feature on page 4-14.
Pairing Modes
When operating with the cradle, two modes of pairing are supported:
• Locked Pairing Mode - When a cradle is paired (connected) to the scanner any attempt to connect a different scanner, by
either scanning the PAIR bar code on the cradle or by inserting it into the cradle with the pairing on contacts feature enabled,
is rejected. The currently connected scanner maintains its connection. In this mode, connection maintenance interval must
be set.
• Unlocked Pairing Mode (Point-to-Point only) - A new scanner can be paired (connected) to a cradle at any time by either
scanning the PAIR bar code on the cradle or by inserting it into the cradle with the pairing on contacts feature enabled. The
original scanner is disconnected from the cradle in favor of the new one.
• Lock Override (Point-to-Point only) - Overrides a locked scanner base pairing to connect a new scanner (see page 4-19).
In Multipoint-to-Point mode, when the piconet is full (three scanners connected to the cradle), one of the
connected scanners must be disconnected by scanning Unpair (page 4-20), before a new scanner can join
the piconet.
