To System Designers:
•When introducing the Bluetooth®adapter in those systems that could affect human lives (e.g.,
medicines management system), develop applications carefully through redundancy and safety
design which avoids the feasibility of affecting human lives even if a data error occurs.
•When using the RS-232C interface, use the dedicated AC adapter only.
Failure to do so could result in fire.
•If the interface cable or AC adapter cable (if connected) is damaged, e.g., exposed or broken lead
wires, stop using it and contact your nearest dealer.
Failure to do so could result in a fire or electrical shock.
•Never bring any metals into contact with the terminals in connectors.
Doing so could produce a large current through the Bluetooth®adapter, resulting in heat or fire, as
well as damage to the Bluetooth®adapter.
•Never use the Bluetooth®adapter on the line voltage other than the specified level.
Doing so could cause the Bluetooth®adapter to break or burn.
•Do not use the Bluetooth®adapter where any inflammable gases may be emitted.
Doing so could cause fire.
•Keep the AC adapter away from water.
Failure to do so could cause fire or electrical shock.
•Do not scratch, modify, bend, twist, pull, or heat the interface cable or AC adapter cable (if
connected). Do not place heavy material on it or allow it to get pressed under heavy material.
Doing so could break cables, resulting in a fire.
•If smoke, abnormal odors or noises come from the Bluetooth®adapter, immediately switch off the
host PC, unplug the AC adapter (if connected) from the electrical outlet and the interface cable from
the host PC, and contact your nearest dealer.
Failure to do so could cause fire or electrical shock.
•If foreign material or water gets into the Bluetooth®adapter, immediately unplug the AC adapter (if
connected) from the electrical outlet and the interface cable from the host PC, and contact your
nearest dealer.
Failure to do so could cause fire or electrical shock.
•If you drop the Bluetooth®adapter so as to affect the operation or damage its housing, switch off the
host PC, unplug the AC adapter (if connected) and the interface cable, and contact your nearest
dealer.
Failure to do so could cause fire or electrical shock.
iii

Never
disassemble
•Never disassemble or modify the Bluetooth®adapter; doing so could result in an accident such as
break or fire.
Doing so could result in a fire or electrical shock.
•Do not put the Bluetooth®adapter on an unstable or inclined plane.
The Bluetooth®adapter may drop, creating injuries.
•Never put the Bluetooth®adapter in places where there are excessively high temperatures, such as
inside closed-up automobiles, or in places exposed to direct sunlight.
Doing so could affect the housing or parts, resulting in a fire.
•Avoid using the Bluetooth®adapter in extremely humid areas, or where there are drastic
temperature changes.
Moisture will get into the Bluetooth®adapter, resulting in malfunction, fire or electrical shock.
•Do not place the Bluetooth®adapter anyplace where it may be subjected to oily smoke or steam,
e.g., near a cooking range or humidifier.
Doing so could result in a fire or electrical shock.
•Never cover or wrap up the Bluetooth®adapter or AC adapter in a cloth or blanket.
Doing so could cause the unit to heat up inside, deforming its housing, resulting in a fire.
Always use the Bluetooth®adapter and AC adapter in a well-ventilated area.
•Keep the AC adapter cable away from any heating equipment.
Failure to do so could melt the sheathing, resulting in a fire or electrical shock.
•Do not insert or drop foreign materials such as metals or anything inflammable through the openings
or vents into the Bluetooth®adapter.
Doing so could result in a fire or electrical shock.
•Do not scratch or modify the Bluetooth®adapter or its interface cable. Do not bend, twist, pull, or
heat the cable.
Doing so could damage the Bluetooth®adapter or its interface cable, creating a fire hazard.
•Do not use the Bluetooth®adapter if your hands are wet or damp.
Doing so could result in an electrical shock.
•Never use chemicals or organic solvents such as benzene and thinner to clean the housing. Do not
apply insecticide to the Bluetooth®adapter.
Doing so could result in a marred or cracked housing, electrical shock or fire.
•Do not use the Bluetooth®adapter with anti-slip gloves containing plasticizer.
The Bluetooth®adapter housing may be broken, creating injuries, electrical shock, or fire.

Bluetooth®Wireless Communication Link
The Bluetooth®adapter BA20-RU 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 Serial port profile
Communications range (reference value*1) Max. 10 m, with no obstructions
*1 This is a value for the communication between the Bluetooth®adapter and the DENSO WAVE wireless scanner.
Communication range varies depending on the device to communicate with and operating environment.
Wireless networking requires a stable radio environment. Not all operating environments provide this. In particular,
note that
•Using the Bluetooth®adapter 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 Bluetooth®
adapter 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 Bluetooth®adapter 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 Bluetooth
®
adapter, be sure to confirm that the adapter
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.

Chapter 2 Connection to the Host Computer
The Bluetooth®adapter connects to the host computer via any of the following three interfaces.
•USB keyboard interface (default)* (See Section 2.3)
•USB-COM interface (See Section 2.3)
•RS-232C interface (See Section 2.4)
Note: Using a USB keyboard interface requires selecting the keyboard type that matches the one at the host computer
with the configuration software “BA Setting”. Using any other interface requires changing the Bluetooth®adapter
settings also with the configuration software. In any case using the configuration software, it is necessary to use a
USB-COM interface (See Section 2.3) or RS-232C interface (See Section 2.4) to the host.
2.1 Location of the Bluetooth®Adapter
Locate the Bluetooth®adapter, observing the following notes in order to secure the wireless link between the
Bluetooth®adapter and the scanner.
- Do not locate the Bluetooth®adapter on a metallic desk or wall. If it is unavoidable, keep the Bluetooth®adapter
away at least 15 cm (5.9") from the metallic surface.
- Make sure that there is no metallic obstruction in the wireless path between the Bluetooth®adapter and the scanner.
2.2 Connection between Interface Cable and Bluetooth®Adapter
Connect the desired interface cable to the corresponding interface connector provided on the side of the Bluetooth®
adapter.
Note: Hold the Bluetooth®adapter, align the adapter's connector and interface cable connector with each other, and
fully insert the interface cable into the adapter's connector.
