Scanner Cradle
The scanner cradle serves as a stand, charger, and host interface for the scanner. The cradle sits on a desktop or mounts on a vertical
surface (such as a wall). For more information about mounting options and procedures, refer to the documentation included with the
cradle.
There are two versions of the cradle:
• Charging cradle with radio: When the cordless scanner is paired to the cradle, all communication between the scanner
and the host computer is accomplished through the cradle. Each bar code contains programming instructions or other data
unique to the bar code pattern. The scanner is paired to the cradle and transmits bar code data to the cradle via Bluetooth
Technology Profile Support. The cradle then sends that information via an interface cable to the host computer for
interpretation.
• Charge-only cradle: This cradle serves as a stand and battery charger. It does not contain a radio and has no
communication capability.
For more information about communication between the scanner, cradle and host, see Chapter 4, Radio
Communications.
Connecting the Cradle
Important: Connect the interface cable and power supply (if necessary) in the following order to ensure proper operation of the
scanner and cradle:
1. If a power supply is connected to the cradle, disconnect it. See Figure 1-5.
2. If using an interface cable, insert the cable into the cradle’s host port.
3. If using a power supply that connects to the interface cable, insert this power supply into the power connector on the
interface cable, and the other end to an AC supply.
4. Insert the other end of the interface cable into the appropriate port on the host computer (see the specific host chapter for
information on host connections).
5. If using an external power supply (if required by the interface, or to allow fast charging of the scanner), insert the power
cable into the power port on the back of the cradle, and connect the power supply to an approved AC supply (see the
STB4208/4278 Cradle Quick Reference Guide for more information).
