Bluetooth®Wireless Communication Link
The scanner AT27Q-SB uses Bluetooth®wireless networking technology.
Item Specifications
Standard Bluetooth®Specification Ver. 2.1+EDR
Radio output Class 2 (maximum 2.5 mW)
Profile(s) supported SPP (Serial Port Profile), HID (Human Interface Device Profile)
Communications range (reference value*1) Max. 10 m, with no obstructions
*1This value is for wireless networking between the scanner and the BA11/10-RKU communications adapter. The
communications range varies with the equipment used and the operating environment.
Wireless networking requires a stable radio environment. Not all operating environments provide this. In particular,
note that
Using the scanner in close proximity to other wireless LAN equipment operating in the same frequency band (2.4
GHz) risks radio interference that can reduce throughput or even entirely block wireless networking.
Microwave ovens, industrial heating equipment, high-frequency medical equipment, and other equipment using the
2.4 GHz band can sometimes block wireless networking.
Electromagnetic noise from computers, refrigerators, and other home appliances can sometimes block wireless
networking.
The following environments can sometimes block wireless networking.
- Metal objects or particles in the vicinity
- Metal walls around the area
- Excessive vibration
The communications range of 10 m given above is merely a reference value assuming a clear line of sight. Reliable
wireless networking is by no means guaranteed at 10 m for all combinations of equipment used and operating
environments. Some combinations might even work for greater distances, but be sure to confirm that the scanner
link operates properly before introducing the link operation.
NOTE: To System Designers:
Before developing applications, make sure that the intended environment is free of the interference factors
above and thus actually capable of supporting link operation.
When introducing the scanner into an environment where equipment using radio waves in the 2.4 GHz
band operates or when introducing such equipment after the introduction of the scanner, be sure to confir
m
that the scanner radio link operates properly with all equipment being in operation beforehand.
If the environment of the radio communications system is changed after the introduction (e.g., newly
installed household appliances and movement/addition of shelves or objects), then confirm that the radio
link operates properly again before the actual use.

ix
Care and Maintenance
■Proper Care of the reading window
Dust or dirt accumulating on the clear plate of the code reading window will affect reading performance. If you use
the scanner in dusty areas, therefore, periodically check the clear plate and clean it if dusty.
To clean the plate, first blow the dust away with an airbrush. Then wipe the plate with a cotton swab or the similar
soft one gently.
If sand or hard particles have accumulated, never rub the plate; doing so will scratch or damage it. Blow the
particles away with an airbrush or a soft brush.
■Proper Care of the Scanner body
Wipe any dirt from the Scanner body with a dry, soft cloth.
Note
• Never use substances such as benzene or alcohol, as this may cause the housing to be marred or paint to peel off.
• If excessively dirty, wipe a soft cloth that has been soaked in soapy water (always use neutral detergent) and wrung
out thoroughly.

Chapter 2 BluetoothInterface
For terms relating to Bluetoothwireless communication in this manual, refer to Appendix 3 "BluetoothGlossary."
2.1 Enabling BluetoothInterface
Using the scanner for the first time requires scanning the "Start setting" and "Start operation" QR Code symbols given
in Section 12.2 with the procedure in Section 12.1. Using the scanner when the "End operation" is selected requires
scanning the "Start operation" QR Code symbol. Scanning those code symbols enables the Bluetoothinterface.
Note: Always disable this scanner's Bluetoothinterface in hospitals, aircraft, and other environments where the
Bluetoothradio waves (2400 to 2483.5 MHz, maximum 2.5 mW) present a potential safety risk.
This scanner interprets the "End operation" QR Code symbol as a command to disable the Bluetoothinterface.
Note: When the scanner leaves the factory or it has scanned the "End operation" QR Code(in Section 13.2), it no
longer reads codes except the "Start operation" QR code, the " batch-process" QR code, and the barcode on the
reverse side of the Communications adapter (BA11/10-RKU).

3
2.2 Establishing BluetoothWireless Link
After enabling the Bluetoothinterface, establish a Bluetoothwireless link between the scanner and the
BA11/10-RKU communications adapter (or some other Bluetoothequipment) using the following procedures. Both
devices have slave as their default configuration.
The scanner can configure itself as both a slave (default) and master. To configure it as a slave, use the QR-coded
parameter menu or configuration software (ScannerSetting_2D)*; to configure it as a master, it is necessary to specify
the slave's Bluetoothaddress to the scanner.
Tip: In addition to "As a master" and "As a slave" parameters, the configuration software provides a choice of "No
slave/master configuration change" (see page 68) that prevents the Bluetoothwireless link from getting broken when
you change other parameters with the configuration software or batch-process QR Code symbols (see Chapter 4).
Scanner as Slave (default)
The scanner is a slave by default. This slave can establish a Bluetoothwireless link with the BA11/10-RKU
communications adapter (or some other Bluetoothequipment) as a master without special communication
procedures.
(1) If the scanner is currently a master, use the scanner to read the "Configure as slave" QR Code symbol given in
Section 12.2 using the procedure in Section 12.1 to switch it to slave operation.
(2) Wait for the scanner to beep three times, press the scanner's trigger switch, and wait approximately two minutes
(default) for the master device to connect to this slave.
(3) Configure the communications adapter (or some other Bluetoothequipment) as a master and specify the
scanner's Bluetoothaddress.
For the communications adapter, use the configuration software (BASetting). (For other Bluetoothequipment,
use the procedures set forth in the user's manual.)
(4) Wait for the communications adapter (or some other Bluetoothequipment) to establish a Bluetoothwireless
link with the scanner as a slave.
(5) Wait for the scanner to beep twice and the indicator LED to turn green (for 0.5 second), indicating a successful
connection.
Note: If the master device cannot discover the scanner available in the vicinity, set the longer inquiry time and let
the master device search it again.
Note: In response to the connection request from the master device, the scanner unconditionally connects to it. No
Bluetoothpasskey is required to specify.
* The configuration software (ScannerSetting_2D) is available as free downloads from our website at
http://www.denso-wave.com/.

4
Scanner as Master
To configure the scanner as a master and the communications adapter (or some other Bluetoothequipment) as a slave,
follow the sample procedures given below and specify the slave's Bluetoothaddress to the scanner. The connection
ratio of the scanner and slave device should be 1:1.
Using the communications adapter (example)
(1) Use the scanner to read the bar code (communications adapter's Bluetoothaddress) on the back of the
communications adapter.
(2) Wait for the scanner to configure itself as a master and establish a Bluetoothwireless link with the
communications adapter.
(3) Wait for the scanner to beep twice and the indicator LED to turn green (for 0.5 second).
Using some other Bluetoothdevice (example)
(1) Confirm the device's Bluetoothaddress.
For the instructions on how to confirm, see the user's manual.
(2) With the configuration software (ScannerSetting_2D)*, generate a "Bluetoothaddress" code that specifies the
equipment's Bluetoothaddress to the scanner.
When using a commercially available code generator, generate it in the following format.
Code type Data format
QR Code Model 1, 2 %% ADDRXXXXXXXXXXXX %%
CODE 128 Code Set A ADDRXXXXXXXXXXXX
(Note) XXXXXXXXXXXX should be a Bluetoothaddress in hexadecimal.
Example: Bluetoothaddress 000AF1234567
ADDR000AF1234567
(3) Use the scanner to read the "Bluetoothaddress" code.
(4) Wait for the scanner as a master to establish a Bluetoothwireless link with the specified Bluetoothdevice.
(5) Wait for the scanner to beep twice and the indicator LED to turn green (for 0.5 second), indicating a successful
connection.
Note: The scanner does not check the Bluetoothpasskey when connecting to the slave device. If the slave device is so
set up that it asks for the Bluetoothpasskey, therefore, modify the slave's setting to unconditionally connect to the master
device, using the procedures set forth in the user's manual.

5

2.3 Breaking BluetoothWireless Links
Holding down the trigger switch for 5 seconds or scanning the "Break Bluetoothwireless link" QR Code symbol
forcibly breaks the scanner's Bluetoothwireless link. (The QR Code symbol is given in Section 12.2 and its
procedure in Section 12.1.)
Note: Breaking the Bluetoothwireless link does not disable the Bluetoothinterface. To disable it, scan the "End
operation" QR Code symbol.
2.4 Reestablishing BluetoothWireless Links
When the scanner's Bluetoothwireless link has been broken by any of the following events, pressing the trigger
switch reestablishes the Bluetoothwireless link. The scanner as a slave waits for a connection request from the
master; the scanner as a master connects to a target slave.
- Scanning the "Break Bluetoothwireless link" QR Code symbol (See Sections 12.1 and 12.2.)
- Holding down the trigger switch to break the Bluetoothwireless link
- Modifying the scanner configuration with the configuration software (ScannerSetting_2D)
