1 | Introduction
Overview
Socket’s Cordless Serial Adapter (CSA) with Bluetooth Wireless
Technology eliminates your conventional RS-232 serial cable, providing an
easy-to-use, invisible connection with superior freedom of movement. This
tiny adapter allows any device with a standard 9-pin serial port to
communicate wirelessly. You can communicate with another CSA or other
Bluetooth enabled devices such as a laptop computer, PDA or mobile
phone. Take advantage of Personal Area Networking quickly and easily.
You don't need to install any drivers on the host device — just plug the
CSA into the 9-pin serial port on your industrial equipment and wirelessly
download the information you need to any Bluetooth enabled notebook,
Pocket PC, Palm or Mac OS device. Reduce costs by decreasing cycle
times for equipment maintenance and servicing through easier access to
serial ports in difficult or dangerous-to-access areas. Do you have cabled
connections you would like to replace with a cordless solution? Attach a
CSA on each side, and make bulky cables a thing of the past.
The CSA communicates over the Bluetooth Serial Port Profile. The adapter
can be powered from either the included AC power adapter or from the host
device over Pin 9 on the CSA.
Common Usage Scenarios
Scenario 1: Set up a CSA pair as serial cable replacement.
Example: Replace
your printer cable
with a wireless
Bluetooth
connection between
your laptop and
printer.
Scenario 2: Set up the CSA as a passive serial Bluetooth receiver.
Example: Use the CSA to
Bluetooth enable industrial
equipment, which you can
then control and monitor
from a Bluetooth enabled
Pocket PC.

CSA connects either automatically or with manual initiation.
Depending on how your configured the CSA, it may automatically connect
with the remote device, or you may need to manually initiate a connection.
In the previous scenarios, the following should happen:
SCENARIO 1: Set up a CSA pair for cable replacement.
After you attach the CSA to each device (with each powered on), they
should automatically try to connect.
Example: After you attach the initiator CSA to the laptop and the acceptor
CSA to the printer, the two CSA’s will automatically try to connect.
SCENARIO 2: Set up one CSA as passive serial Bluetooth receiver.
After you attach the CSA, your device will be discoverable and ready to
accept a Bluetooth connection. Perform a device discovery from the
initiator device, then commence the connection.
Example: The industrial equipment with the CSA will be discoverable and
ready to accept a Bluetooth connection. Perform a device discovery from
the Bluetooth enabled Pocket PC, then start the connection.
Important!
Make sure you manually configure your baud rate and other settings in any
third-party applications used with the CSA. Auto-detect and Plug and Play
functions are not reliable with Bluetooth, and the CSA may not work
properly unless you manually enter the correct settings.

Appendix B Safety and Usage Tips
About Bluetooth and Health
Bluetooth wireless technology allows you to use short-range radio signals to
connect a variety of devices, such as mobile phones, Pocket PCs, notebook
computers, printers, LAN access points, and many other devices at home or
work. These radio signals replace the cables that have traditionally
connected these devices. Bluetooth products have small radio transmitters
and receivers. Output power is normally very low, only 1 mW (1/1000 of a
watt). This gives a working range of approximately 10 meters. The
maximum exposure levels from Bluetooth products are far below
recommended safety guidelines. At most, typical Bluetooth devices (1mW)
reach only one percent of the prescribed safety levels.
Product Care
•
Do not expose your product to liquid, moisture or extreme humidity.
There is a risk of electrical shock.
•
•
Do not expose your product to extreme high or low temperatures.
Do not expose your product to lit candles, cigarettes, or cigars, or to
open flames, etc.
•
•
•
Do not drop, throw or try to bend the product, as rough treatment could
damage it.
Do not paint your product, as the paint could obstruct parts and prevent
normal use.
Do not attempt to disassemble your product: a broken warranty seal will void
the warranty. There is danger of fires, electrical shock, damage to the unit,
and injury. The product does not contain consumer serviceable components.
Treat your product with care. Keep in a clean and dust-free place.
Changes or modifications of this product, not expressly approved by
Socket, may void the user’s authority to operate the equipment.
The Cordless Serial Adapter is susceptible to physical damage. Do not
exert excessive force on it, or permanent damage can occur!
If the CSA gives any electromagnetic interference to other devices,
either remove it from the host device or unplug it from its power source.
Do not insert any metal objects such as staples or paper clips into the
unit.
•
•
•
•
•
•
Do not place the unit in direct sunlight, in a closed car, near a heating
device or any other location where the temperature may become high.
Do not expose the unit to high levels of dust.
Do not use the unit near a microwave oven or in areas where there is a
risk of electrical shock, static electricity or electromagnetic interference.
•
•
36

Radio Frequency Exposure
Your Cordless Serial Adapter is a radio transmitter and receiver. When in
operation, it communicates with a Bluetooth enabled computer, printer or
other device by receiving and transmitting radio frequency (RF) magnetic
fields in the frequency range 2400 to 2500 MHz. The output power of the
radio transmitter is 0.001 Watt. The Cordless Serial Adapter is designed to
be in compliance with the RF exposure limits set by national authorities and
antennas or radio transmitters.

Appendix D Troubleshooting
SYMPTOM: The Configuration Utility is not working properly
(e.g., I cannot read the settings from the CSA) and/or I get an
error message that says “Unable to open the COM port.”
POSSIBLE REASONS
The CSA is not attached properly to
your computer.
SOLUTION
Properly insert the CSA, pushing it into
your computer’s serial port as far as it will
go.
The CSA does not have power. The
LED is not blinking.
Use the AC adapter to connect the CSA to
an electrical outlet.
The CSA currently is configured with
automatic connections and DTR
disabled, and the remote device is
within range. Thus, you are currently
connected to the remote device.
ActiveSync has control of the port
where the CSA is attached.
Remove the remote target from range.
In the ActiveSync connection settings,
make sure a serial cable connection is not
allowed at the COM port where you
attached the CSA.
Your computer is already connected to Disable the conflicting connection.
another device using the same COM
port that the CSA is trying to access.
SYMPTOM: The CSA is not communicating properly with my
third party software.
POSSIBLE REASONS
You configured the CSA and/or the
third party software incorrectly.
SOLUTION
Make sure the CSA and third party
software are set for the same baud rate and
other settings.
You are using auto-detect and Plug
and Play functions.
Auto-detect and Plug and Play functions
do not work reliably with Bluetooth. Make
sure you manually enter the baud rate and
other settings to match those of your local
host device’s serial port.
