Product Description
The MultiConnect BT Serial-to-Bluetooth adapter utilizes Bluetooth technology to provide a secure,
standards-based wireless connection between a host and a peripheral device. Providing wireless data
transfer up to 100 meters, it completely eliminates the need for serial cable connections.
General Safety
The adapter is designed and intended to be used in either fixed or mobile applications. In the “Fixed”
application, the device is physically secured at one location and not easily moved to another location. In
the “Mobile” application, the device may be regularly moved to different locations.
Caution! Maintain a separation distance of at least 20 cm (8 inches) between the transmitter’s antenna
and the body of the user or nearby persons. The adapter is not designed for, nor intended to be, used in
applications within 20 cm (8 inches) of the body of the user. Such uses are strictly prohibited.
Radio Frequency Interference
Avoid possible radio frequency (RF) interference by carefully following the safety guidelines below.
• Switch OFF the Adapter when in an aircraft. The use of cellular telephones in aircraft is illegal. It
may endanger the operation of the aircraft and/or disrupt the cellular network. Failure to observe
this instruction may lead to suspension or denial of cellular telephone services to the offender,
legal action, or both.
• Switch OFF the Adapter in the vicinity of gasoline or diesel-fuel pumps or before filling a vehicle
with fuel.
• Switch OFF the Adapter in hospitals and any other place where medical equipment may be in use.
• Respect restrictions on the use of radio equipment in fuel depots, chemical plants, or where
blasting operations are in progress.
• There may be a hazard associated with the operation of your Adapter in the vicinity of
inadequately protected personal medical devices such as hearing aids and pacemakers. Consult
the manufacturers of the medical device to determine if it is adequately protected.
• Operation of the Adapter in the vicinity of other electronic equipment may cause interference if the
equipment is inadequately protected. Observe any warning signs and manufacturers’
recommendations.
Vehicle Safety
• Do not use your Adapter while driving.
• Respect national regulations on the use of cellular telephones in vehicles. Road safety always
comes first.
• If incorrectly installed in a vehicle, the operation of adapter could interfere with the correct
functioning of vehicle electronics. To avoid such problems, be sure that the installation has been
performed by qualified personnel. Verification of the protection of vehicle electronics should be
part of the installation.
• The use of an alert device to operate a vehicle’s lights or horn on public roads is not permitted.
Handling Precautions
All devices must be handled with certain precautions to avoid damage due to the accumulation of static
charge. Although input protection circuitry has been incorporated into the devices to minimize the effect of
this static buildup, proper precautions should be taken to avoid exposure to electrostatic discharge during
handing and operation.

Chapter 1 – Description and Specifications
Maintenance of the Serial-to-Bluetooth Adapter
Your adapter is the product of advanced engineering, design and craftsmanship and should be treated
with care. The suggestions below will help you to enjoy this product for many years.
• Do not expose the adapter to any extreme environment where the temperature or humidity is high.
• Do not attempt to disassemble the adapter. There are no user serviceable parts inside.
• Do not expose the adapter to water, rain or spilled beverages. It is not waterproof.
• Do not abuse your adapter by dropping, knocking, or violently shaking it. Rough handling can
damage it.
• Do not place the adapter alongside computer discs, credit or travel cards, or other magnetic
media. The information contained on discs or cards may be affected by the phone.
• The use of accessories not authorized by Multi-Tech or not compliant with Multi-Tech’s accessory
specifications may invalidate the warranty of the MultiConnect Adapter.
• In the unlikely event of a fault in the adapter, contact Multi-Tech Technical Support.

Transmit Data. This LED is lit when adapter is transmitting data to another adapter.
Receive Data. This LED is lit when the adapter is receiving data from another adapter.
Carrier Detect. This LED is lit when the adapter detects a valid carrier signal from another
adapter.
It is on when the adapter is communicating with the other adapter and off when the link is
broken.
Terminal Ready. (Also called Data Terminal Ready.) This LED indicates the PC is turned
on and ready to communicate. This LED is lit when a data communications program
initializes the adapter. It goes off when the communications program disconnects the COM
port. When it goes off, a connected adapter will disconnect.
Power. This LED Indicates the presence of DC power when lit.
