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.

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

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 Bluetooth-
enabled device (PC/PDA), you must set the Bluetooth serial
adapter in slave mode (Switch 4 = Off).

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!

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:

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
s%OXH/('RQVODYHDGDSWHUZLOOVORZO\EOLQNRQFHevery 2-3 seconds)
s%OXH/('RQPDVWHUDGDSWHUZLOOUDSLGO\EOLQN4. 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.
