2 CR2278-PC Presentation Cradle
Introduction
The CR2278-PC (presentation) cordless digital scanner cradle acts as
charger and radio communication interface for the DS2278 cordless digital
scanner. The CR2278-PC can sit on a tabletop or be mounted with an
L-bracket (supplied by a third party vendor).
The cradle receives data from the digital scanner via a Bluetooth radio,
and sends that data to the host through an attached cable. The cradle also
charges the digital scanner’s internal battery when the digital scanner is
inserted. When inserted into the cradle, the digital scanner can be charged
from an external power supply or a USB cable powered by the host.
This document provides basic instructions on setting up and using the
cradle.
Equipment Supplied
The cradle package includes one CR2278-PC cradle.
Accessories
• Power supply, if necessary.

Cradle Connections
1. Connect the appropriate cable to the power supply and an AC power
source, if necessary. This ensures detection of the host and prevents
inadvertently back powering the cradle from improper detection of the
host.

2. Insert the interface cable into the appropriate port on the host side.
3. Insert the interface cable into the host port in the cradle.
4. Pair the digital scanner to the cradle either by inserting it in the cradle
or by scanning the pairing bar code.
5. If necessary, scan the appropriate host bar code (for non-autodetected
interfaces). Refer to the Product Reference Guide.
Changing the Host Interface
To connect to a different host, or to the same host through a different
cable:
1. Unplug the interface cable from the host.
2. Unplug the power supply from the host cable, if required.
3. Connect the interface cable to the new host, or the new interface cable
to the existing host.
4. Reconnect the power supply, if required.
5. If necessary, scan the appropriate host bar code (for non-autodetected
interfaces). Refer to the Product Reference Guide.
Using a DC Power Supply
The cradle can operate from host supplied power, if available. If host
power is limited or not available, an external DC power supply can be
used with certain host interface cables that support a power jack.
CAUTION Always disconnect the DC power supply BEFORE
disconnecting the cable to the host end or the cradle
may not recognize the new host.
Mounting the Cradle
When placing the cradle on a tabletop, the rubber feet on the bottom of the
cradle provide traction and prevent surface damage.
To mount the cradle to a tabletop or on an L-bracket (using a third party
bracket):
1. Attach the interface and power cables to the cradle (see Cradle
Connections on page 3).
2. Attach the cradle securely to the surface using two M4 screws.
3. Insert the digital scanner in the cradle.

Inserting the Digital Scanner in the Cradle.
CAUTION Do not pour, spray, or spill any liquid on the cradle.
Sending Data to the Host Computer
The cradle receives data from the digital scanner via a wireless radio
connection and transmits it to the host computer via the host cable. The
digital scanner and cradle must be paired for successful wireless
communication.
Pairing
NOTE The pairing bar code that connects the digital scanner to a
cradle is unique to each cradle.
Do not scan data or parameters until pairing completes.
Only when the digital scanner is paired to the cradle, it
automatically tries to reconnect to a remote device when a
disconnection occurs that is due to the radio losing
communication. Refer to the Product Reference Guide for
more information.
Pairing is the process by which a digital scanner initiates communication
with a cradle. To pair the digital scanner with the cradle, scan the pairing
bar code. A high/low/high/low beep sequence indicates that the pairing
bar code was decoded. When a connection between the cradle and digital
scanner is established, a low/high beep sounds.
