Supplying Power To The Cradle; Using The Usb Interface To Supply Power; Lost Connection To Host - Motorola Symbol DS6878 Product Reference Manual

If applicable, thread the interface cable over the cable support hook and run the host and power cables into
6.
their respective cable grooves.
Mount the cradle, as necessary. (For information on mounting the cradle, refer to the documentation included
7.
with the cradle.)
NOTE Disconnect the power supply before changing host cables, or the cradle may not recognize the new host.
Different cables are required for different hosts. The connectors illustrated in each host chapter are
examples only. The connectors may be different from those illustrated, but the steps to connect the cradle
remain the same.

Supplying Power to the Cradle

The cradle receives power from one of two sources:
•
An external power supply.
•
When connected to the host through a host cable that supplies power.
The cradle detects whether the host or the external supply is supplying power. It always draws power from the
external supply when available, regardless of the presence of power from a host.
IMPORTANT For healthcare environments, use cradle p/n CR0078-SC1009BWR and place the ferrite core
(included in box with cradle) on the power supply (refer to the Power Supply Ferrite Installation
instructions included in the box).

Using the USB Interface to Supply Power

When the cradle is connected to the host via the USB interface, it can be powered by the USB port instead of an
external power supply. Powering from a USB host limits charging. The digital scanner charges at a slower rate than
when charging from an external power supply.
NOTE The radio link functions normally when the cradle draws power from a USB host.

Lost Connection to Host

If scanned data does not transmit to the cradle's host, ensure that all cables are firmly inserted and the power
supply is connected to an appropriate AC outlet. If scanned data still does not transmit to the host, reestablish a
connection with the host:
Disconnect the power supply from the cradle.
1.
Disconnect the host interface cable from the cradle.
2.
Wait three seconds.
3.
Reconnect the host interface cable to the cradle.
4.
Reconnect the power supply to the cradle, if required.
5.
Reestablish pairing with the cradle by scanning the pairing bar code.
6.
NOTE The CR0078-S does not always require a power supply whereas the CR0008-S always requires a power
supply.
