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.
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 ON Slave mode: Switch 4 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.
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.
Basic Configuration 2 Set device mode 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). 3 Plug in Plug in the Bluetooth serial adapter to your serial device. If your device has a male RS232 interface, use the included null modem adapter. 4 Power ON Plug in the power cable to your Bluetooth serial adapter; the blue LED will start blinking after approximately fifteen (15) seconds.
Instructions Basic Configuration 5 Pair and Connect 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.
Basic Configuration Widcomm Bluetooth Software 1.
Basic Configuration 2. When found, pair to the Bluetooth serial adapter. The default PIN code is “1234” 3. Once paired, the unit will display the services available.The service offered by this unit is the Serial Port Profile (SPP).To establish a connection, right-click on it and select “Connect to Bluetooth Serial Port.
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.
Basic Configuration SCENARIO 2: Interconnecting two IOGEAR Bluetooth serial adapters When interconnecting two IOGEAR Bluetooth serial adapters, there are three methods you can use to pair and connect them: 1. Auto-pairing 2. Back-to-Back 3.
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.
Basic Configuration 5 Finished 1 successful connection, the blue LED on both adapters will turn off and remain off Upon 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) Bluetooth Serial Adapters.
Basic Configuration 7 4 Back-to-Back Connect the serial adapters back-to-back, using the included Null Modem adapter 5 Power ON Power ON both Serial adapters 6 Pairing Almost instantly, the Blue LED will light up and stay solid; this indicates successful pairing 7 Power OFF Disconnect both serial adapters and Power them OFF 20
Basic Configuration 8 Plug in You may now connect each adapter to your desired serial device for communication.
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.
Advanced Configuration Configuring Serial Adapter 1 Set baud rate Set the Baud rate on the Serial adapter to 9600 (see table 1 on page 9) 2 Plug in Plug the Bluetooth serial adapter to an available serial port on your computer (Do NOT power on the serial adapter yet). 3 Open Hyper Terminal 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.
Advanced Configuration Note: HyperTerminal may also be found under Start Programs Accessories Communications HyperTerminal 24 18
Advanced Configuration 4 Specify COM port When prompted for the COM port number being used, make sure to select the correct one. If you only have one physical com port in your computer, this will probably be COM 1 However, if you’re unsure, contact your computer/motherboard manufacturer. In the case above, we have several COM ports available, and we are using COM 1.
Advanced Configuration 5 Port Settings Make sure to set your settings as shown on the window below: 26 20
Advanced Configuration 6 Power on Once you have initiated your HyperTerminal session, power ON the Serial adapter. It will display the words “PR” to indicate it is in configuration mode. Within six (6) seconds, enter the words “AT” (without quotes) to invoke the configuration menu Note: If this does not happen, simply power Off the serial adapter and back ON again (with HyperTerminal open), and enter “AT” within six seconds.
Advanced Configuration 7 Make Changes Make your selection from the menu to change any desired settings. 8 Exit and apply changes To apply any changes, you must select option E (Exit configuration) and accept the changes. 9 Power Cycle Finally, power cycle the adapter by turning it off, then back on again. For more details on the HyperTerminal configuration menu, please see the Appendix on page 31.
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.
