installing BioExplorer



Install PN Windows DriverFound_new_hardware_b


First step in getting your new product working is to install a Windows driver to allow BioExlorer to talk to the Wiz over the PC’s COM port.

If you have previously installed a PN product on this computer then the driver install may proceed silently. Since each new device is treated by Windows as a unique device, a separate COM port is assigned for each separate device. The following discussion assumes this is a first time installation.

If your computer is connected to the internet, then it is recommended that you allow Windows to automatically install the driver from the Microsoft on-line repository. When the PN wireless dongle or a PN Wiz series device is first plugged in, Windows ‘New Found Hardware’ wizard will give you the option to allow Windows to install the driver automatically. Allow this and be prepared to wait a few minutes for the search to execute. You will be asked to allow Windows to search a _second_ time. You must also allow this.

If your computer is not connected to the internet or if the installation of the driver had previously failed. In this case, run this auto-install executable. Double click this file to start a silent install of the driver and COM port.

The single piece of information arising out of this driver install that needs to be manually advised to BioExplorer is the COM port number (eg “COM3”) assigned by Windows to the driver. Windows will flash this momentarily as part of the install procedure, otherwise you can access the information via the Windows Device Manager (see Windows Control Panel) under “COM ports”. Once this install is completed, you will be ready to use your hardware.




Install BioExplorer software and security dongle

BioExplorer software is free to download. However to run the software a hardware security dongle or “HASP”, which plugs into a USB port, is required to be purchased. Download and run the latest BioExplorer version here. At the conclusion of the installation, you will also be prompted to install a driver for the security dongle.

BioExplorer is a platform. It needs “designs” to tell it what to do. So next step is to copy the sample designs here into the “Designs” sub-directory in the BioExplorer folder normally found at C:\Program Files\BioExplorer\.


Designs often need video files and audio files as feedback media. So final step is to copy across the video files found here to the “media” sub-directory in the BioExplorer folder.

Designs which use DVDs as the feedback media need a decoder. This is a potential source of problems since PCs will often have installed multiple decoders. A free decoder, DScaler,  has been found to work with most machines. It can be downloaded and installed here.

Configure BioExplorer for the Wiz

With the Wiz plugged into the USB port, run BioExplorer. In the BioExplorer Drop Down Menu bar, click “BioExplorer”, and in the drop down menu select “Devices..”


Choose “Add..”, then in the drop down list select “PN-Wiz” as the New Device. A new Window will appear labelled “Wiz”. This window contains commands to configure the Wiz. This is discussed in more detail later.

Tick the box to make it the active driver, then click on it to highlight it, then select “Properties…”

In the Properties window, set the Port to the COM port assigned by Windows to the PN driver (eg “COM3”). It will be possibly be the last COM port on the drop down list. Other parameters (Baud Rate etc) should not be changed.

In the BioExplorer Status Bar there should now be an entry: “PN Wiz on COMx” and with the Wiz plugged in,the Status Bar should also indicate “connected”.

Next we need to choose a design to run. In the BioExplorer Drop Down Menu bar choose “Design” and “Open..”. Navigate to the BioExplorer folder and the “Designs” sub-directory. Choose one of the designes that you copied earlier:   wiz_test_Mode2_Mode4.bxd

Press the green triangle between the Drop Down bar and the Status bar to “Play”. In the Wiz Window, toggle the “Power” function to see that BioExplorer is indeed commanding the Wiz. When Power is applied, the Wiz will initiate a test tone for a few seconds (4, 8, 16 and 32Hz each for one second), then it will start to read eeg signals. In the Wiz Window, select Mode “ExG”, then select Helper Function “Test Tone”. The startup sequence of tones in now repeated continuously. You have verified that your system is performing OK.



Modify existing BioExplorer designs to operate with the Wiznew_found_hardware_complete_b

Having added “PN_Wiz” to the list of drivers in the BioExplorer Device Manager, and checked the box to enable it, existing BioExplorer designs intended for the Pendant series of products can be used with the Wiz by simply right clicking on the Source object in the Signal Diagram view, choosing Properties and choosing a PN Wiz channel from the drop down list. The Wiz itself should be set to Mode 2 for EEG and Mode 1 for HEG.

Features such as electronic linking of electrodes, DC/AC coupling, and HEG calibration are available to these older designs because these functions don’t rely on the BioExplorer design to work.

On the other hand, to take advantage of new features like electrode impedance measurement, this does rely on the design and modifications to the design are necessary to incorporate it.
