4. Alternative Product Configuration
4.1. Accessing the configuration menus and commands.
The adapter’s configuration menu is available at any time that there is no Bluetooth radio connection established
with another device (unless of course you have selected the option to disable the menu). As soon as a Bluetooth
connection is made, the data sent to the Adapter will be sent over the radio link to the remote device. A short time
after the Bluetooth connection is broken, the configuration menu’s become available again.
Sending a single “Carriage Return” character to the Adapter whilst no Bluetooth connection exists will activate the
initial main menu, or typing the command required will initiate the appropriate response. Both the menu and
command list are documented further below.
The example given below to connect to the configuration menus is performed in Windows XP using HyperTerminal,
a terminal application that ships with Windows. If you are using a different operating system, you will need a similar
“terminal” or “tty” type application (e.g. minicom), which talks directly to a serial port in that operating system. If you
are using a different version of Windows the specific steps to invoke and use the HyperTerminal application may be
slightly different – please refer to your operating system documentation if you need further help in this respect.
First, connect the adapter, along with the supplied gender changer, to an available serial port on your computer. In
this example, the COM1 port on the PC has been used.
Ensure the power adapter is connected and switched on (the leftmost green LED on the Adapter should light.
Start HyperTerminal by clicking “Start\All Programs\Accessories\Communications\HyperTerminal”.
If you are running HyperTerminal for the first time you will be prompted
for information about your location. This section must be filled in, but is
not used for our purposes, so you are free to add anything here.
The next screen (left) is just to name this instance of the connection.
You are free to name this as anything except an existing device name
(e.g. COM1).
