Operation  
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  
Switfches 1-3  
DIP Switches 1, 2, and 3 are used to configure the baud rate.  
Table 1  
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 on page 22.

Operation  
Switch 4  
DIP Switch 4 is used to set the serial adapter as master or slave:  
Master mode: Switch 4  
Slave mode: Switch 4  
ON  
OFF  
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  
Please note 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  
10  
 
Basic Configuration  
SCENARIO 1:  
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 on page 22.  
Set baud rate  
1
Using table 1 on page 9, 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.

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).  
Plug in  
3
Plug in the Bluetooth serial adapter to your serial device. If your device has a male  
RS232 interface, use the included null modem adapter.  
Power ON  
4
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.

Instructions  
Basic Configuration  
Pair and Connect  
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. Below is an example, using the Widcomm software version 3.0.x

Basic Configuration  
4. Once connected, you will see this  
window indicating the COM port number  
used for connection with the Bluetooth  
serial adapter. In our example below,  
this is COM 4, but most likely it will be  
different in your case.  
IMPORTANT: Make note of this COM port number, as this is the COM port that you  
need to specify for your specific application.  
You’re done!

Basic Configuration  
SCENARIO 2:  
Interconnecting two IOGEAR Bluetooth  
serial adapters  
WheninterconnectingtwoIOGEARBluetooth  
serial adapters, there are three methods you  
can use to pair and connect them:  
1. Auto-pairing  
2. Back-to-Back  
3. Configuration Mode  
17  
 
Basic Configuration  
Note: If you have previously paired to the Bluetooth serial adapter(s), make sure to follow  
the unpairing procedure on page 29 before attempting to connect to a new device.  
Method 1 Auto-paring  
Follow steps below  
Set device mode  
1
Set one serial adapter to Master (switch 4 = ON), and the other to Slave (switch 4 = OFF)  
Set baud rate  
2

After successful connection is made, the blue LED on both serial adapters will turn off and remain  
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 3 HyperTerminal Pairing  
<Please see page31 on Appendix A>

Advanced Configuration  
The Bluetooth serial adapter has an  
embedded configuration menu that  
allows you to change settings for  
your specific application. This menu  
can be accessed via HyperTerminal  
(Windows systems).  
Using this configuration mode, you can  
configure the baud rate, select Peer  
Device (Master only), change PIN  
code, enable/disable authentication,  
and enable/disable encryption.  
NOTE: In order to enter configuration mode, the Bluetooth serial adapter MUST be set  
to 9600 baud rate via the DIP switches.  
22  
 
Advanced Configuration  
Configuring Serial Adapter  
Set baud rate  
1
Set the Baud rate on the Serial adapter to 9600 (see table 1 on page 9)  
Plug in  
2
Plug the Bluetooth serial adapter to an available serial port on your computer (Do NOT  
power on the serial adapter yet).  
Open HyperTerminal  
3
Open HyperTerminal (Go to Start  
Run, and type “hypertrm”) and enter any  
desired name for your hyperterminal session. If the program does not launch, you may  
have to install it from your Windows installation disc.

Unpairing Procedure  
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 three 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 on page 19; which will retain the latest pairing information  
Method3  
Use HyperTerminal configuration menu and select “Clear Pairing Information” option.  
If interconnecting two IOGEAR Bluetooth serial adapters, this must be done on both adapters.  
For details on using the HyperTerminal configuration menu, please see Appendix A on page 31

Option 1: Search for Bluetooth adapter  
Use this option to search for another IOGEAR Bluetooth serial adapter. This option is  
only available if device set as Master. Keep in mind that the other serial adapter must  
be set to slave in order to be discovered.  
Option 2: Change local device name  
Use this option if you wish to change the name displayed by the Bluetooth serial  
adapter  
Option 3: Set authentication mode  
Use this option to enable/disable authentication, based on your preferences. If en-  
abled, any device attempting a connection to the Bluetooth serial adapter will need to  
enter a PIN code; thus, preventing unauthorized users from connecting to the unit.  
33  
 
Appendix A  
Option 4: Set pin key  
The default PIN key for the serial  
adapter is “1234”. If you wish to change  
this to something else, use this option  
Option 5: Set encryption mode  
Use this option to enable/disable  
encryption mode. For example, there  
are some applications that might not  
work properly if encryption is enabled.  
In these cases, you may choose to  
disable this option

Appendix A  
Option 6: Set baud rate  
The dip switches on the serial adapter allow you to set baud rates ranging from 9600 to  
921600. If you need to use a lower baud rate – like 2400bps or 4800bps – use this option.  
The baud rates available for this unit are listed below:  
Baud rate setting
