Radio Communications 5 - 39
Bluetooth Radio, Linking, and Batch Operation
The DS2278 digital scanner has a Bluetooth Class 1 radio which achieves a range of at least 135m / 440ft (open
air, line of sight). The actual range you achieve is influenced by the presence of other radios, shelving and wall
materials as well as which cradle is tested. The environments vary widely and often influence radio ranges.
When the digital scanner goes out of communications range to the base, it can be configured for Batch Mode (see
Batch Mode on page 5-31). The digital scanner has sufficient onboard memory to store 500 bar codes of typical
size (UPC/EAN).
Setting Up an iOS or Android Product To Work With The Digital Scanner
Perform the following steps on each device to establish a link.
HID Keyboard Emulation
1. On the DS2278, scan Human Interface Device (HID) Keyboard Emulation on page 5-5.
2. On an iOS/iPad/iPhone, select Settings > General > Bluetooth and turn Bluetooth On. Choose the DS2278
digital scanner from the list of discovered devices. A link should be established allowing scanning into any
application with keyboard entry.
3. On an Android/ET1/Droid, select Settings > Wireless & networks > Bluetooth (to turn Bluetooth on, if not
already on). Select Bluetooth Settings and choose the DS2278 digital scanner from the list of discovered
devices. (The DS2278 digital scanner normally displays as DS2278 - xxxxxx, where xxxxxx is the serial
number.)
IMPORTANT Android devices, specifically the ET1, may require you to scan a PIN to connect. If so, a PIN
displays on the device. To enter the required PIN, scan the bar code, Variable PIN Code (1) on
page 5-36 then re-attempt connection. When a beep sounds, indicating the digital scanner is
waiting for PIN entry, scan the PIN using the Numeric Bar Codes on page G-1. Incorrect scanned
entries can be deleted by scanning
Cancel on page H-1.
For more information, read the section Variable PIN Code on page 5-36.
