5. If using an external power supply, insert the power cable into the power port on the back of the digital scanner
cradle, and connect the power supply to an approved AC supply (see the cradle’s Quick Reference Guide for
more information).
Figure 1-4 Connecting the Cables to the Cradle
Supplying Power to the Cradle
The cradle receives power from one of two sources:
• An external power supply.
• When connected to a powered host through a host cable that supplies power.
The cradle detects whether the host or an external supply is supplying power. It always draws power from the
external supply when available, regardless of the presence of power from a host.
Using the Host to Supply Power
When connecting the cradle to a powered host, the host can sometimes power the cradle rather than an external
power supply. Consider the following when powering from a host:
• The digital scanner charges at a slower rate than when charging from an external power supply.
• The cradle can charge a digital scanner only in single point mode. An external power supply is required to
charge a digital scanner in multipoint mode.
• A powered USB port provides enough power to the cradle for charging.
• Not all hosts provide enough power to the cradle for charging. For these hosts, connect an external power
supply.
For more information on single and multipoint operation, see Pairing on page 1-9 .
Host Port Power Port
NOTE Disconnect the power supply before changing host cables, or the digital scanner may not recognize the
new host.
Different hosts require different cables. The connectors illustrated in each host chapter are examples only.
The connectors may be different from those illustrated, but the steps to connect the digital scanner are the
same.
NOTE The radio link functions normally when the cradle draws power from a host.
