Factory Settings
When using the Bluetooth serial adapter with your serial devices,
you must make sure that all the settings below match on both
devices; otherwise, you may encounter problems communicating.
Below are the factory default settings of this unit:
Encryption = disabled
Authentication = enabled
PIN key = 1234
Baud rate = selection from dip switch
Stop bits = 1
Parity = none
NOTE: If your serial device requires you to change any of the
default settings, consult the Advanced Configuration section of
the User Manual for more details.
Operation

1
DIP Switches
Switches 1-3
DIP Switches 1, 2, and 3 are used to configure the baud rate.
NOTE: Most computer serial ports only support baud rate up to
115200. For higher baud rates, you may need to install a
high-speed serial card in your computer. In addition, if you need
to set a lower baud rate for your application, see the Advanced
Configuration section in the User manual.
Switch 4
DIP Switch 4 is used to set the serial adapter as master or slave:

Master Mode
If you are interconnecting two IOGEAR Bluetooth adapters,
you must set one of them to master and the other to slave.
Slave Mode
Keep in mind that Bluetooth software applications (like
Widcomm) will only be able to discover and connect to slave
devices.
Therefore, if you are connecting this unit to a serial device to
be accessed by a Bluetooth-enabled PC/PDA at the other
end, make sure to set the IOGEAR Bluetooth serial adapter to
slave mode.

Connecting Bluetooth serial adapter with
Bluetooth-enabled device
The Bluetooth serial adapter has built-in dip switches for fast
and easy configuration.
If you would like to change any of the default settings, consult
the Advanced Configuration section in the User Manual.

Basic Configuration
4
Using table 1, set the baud rate on the Bluetooth serial adapter
by using the on-board DIP switches. Make sure that this baud
rate matches with that used by your serial device.
If you are unsure what baud rate your serial device uses, please
consult the manufacturer of that product.
Plug in the Bluetooth serial adapter to your serial device. If your
device has a male RS232 interface, use the included null
modem adapter.
When using the Bluetooth serial adapter with a Bluetoothenabled device (PC/PDA), you must set the Bluetooth serial
adapter in slave mode (Switch 4 = Off).

Plug in
Step. 4
Power ON
Plug in the power cable to your Bluetooth serial adapter; the blue
LED will start blinking after approximately fifteen (15) seconds.
Once the blue LED is blinking once every 2-3 seconds, this
indicates that the Bluetooth serial adapter is in discovery mode;
in other words, ready to accept a Bluetooth connection.
5
Use your Bluetooth software to search for Bluetooth devices in
range. Once the Bluetooth serial adapter is detected, pair to
it. If prompted for a PIN code, enter “1234” (without the
quotes).
Once paired, establish a connection using the Bluetooth serial
port profile (SPP). If you’re not sure how to do this, please
consult the documentation for your Bluetooth
hardware/software.
Once you have established a Bluetooth serial port connection,
the blue LED will turn off. You’re done!
Step. 5
Pair and Connect

Interconnecting two IOGEAR Bluetooth
serial adapters
When using two IOGEAR Bluetooth serial adapters, there are
two methods you can use to pair and connect them:
1 Auto-pairing
2. Back-to-Back
Pairing Procedure
NOTE: If you have previously paired to the Bluetooth serial
adapter(s), make sure to follow the unpairing procedure
described in the User Manual before attempting to connect to
a new device.

Method 1 Auto-Pairing
The Bluetooth serial adapter (master only) has the capability to
search and automatically connect to another Bluetooth serial
adapter (slave). Follow the steps below:
7
1. Set one serial adapter to Master (Switch 4 = On), and
the other to Slave (Switch 4 = Off).
2. Set matching baud rates as needed
3. Power On both serial adapters and wait approximately
fifteen (15) seconds

every 2-3 seconds)
s%OXH/('RQPDVWHUDGDSWHUZLOOUDSLGO\EOLQN
4. Wait approximately two minutes for the serial adapters
to automatically pair and connect
5. Upon successful connection, the blue LED on both
adapters will turn off and remain off
6. You’re done!
NOTE: Once you have paired both Bluetooth serial
adapters, if you turn them off, please allow approximately
sixty (60) seconds when turning them back on to
re-establish a connection.
Method 2 Back to Back Pairing
Follow this procedure to pair two
(2) IOGEAR Bluetooth Serial Adapters.
8
1. Make sure both Serial adapters are TURNED OFF
2. Set one adapter as Master (Switch 4 = On), and the other
as Slave (Switch 4 = Off)
3. Make sure to set matching Baud rates on both serial
adapters; else they will not be able to communicate.
4. Connect the serial adapters back-to-back, using the
included Null Modem adapter
5. Power ON both Serial adapters
6. Almost instantly, the Blue LED will light up and stay solid;
this indicates successful pairing
7. Disconnect both serial adapters and Power them OFF
8. You may now connect each adapter to your desired serial
device for communication
9. Power ON both serial adapters, the blue LED will blink on
both serial adapters indicating connection is in progress;
which usually takes about sixty (60) seconds
10. After successful connection is made, the blue LED on both
serial adapters will turn off and remain off
NOTE: Once you have paired both Bluetooth serial adapters, if
you turn them off, please allow approximately sixty (60)
seconds when turning them back on to re-establish a
connection.
9
Any time that you want to pair the Bluetooth serial device with
a new Bluetooth adapter/device, you must follow the
unpairing procedure as indicated below.
There are two different methods that you can follow to unpair
the Bluetooth serial adapter
Method 1
1. Power OFF the serial adapter
2. Change the position of Dip Switch 4
3. Power ON the serial adapter. The LED will blink once,
indicating successful unpairing.
4. Power OFF the serial adapter
5. Change dip switch 4 back to its original position
6. You can now pair the Bluetooth serial adapter with
another device
Method 2
If using two (2) IOGEAR Bluetooth serial adapters, follow the
back-to-back pairing procedure indicated earlier; which will
retain the latest pairing information
