Black Box ToolKit version 2 hardware specifications
The new ARM based BBTK v2 is now shipping.
It has its own CPU (like those found in iPads and Android tablets) and onboard RAM for storing samples and uses a range of easy to use external sensors to check timing. It records stimulus events and generates responses with sub-millisecond accuracy and is controlled from a host PC, laptop or netbook via USB. Once running, timing data is independently collected from a second PC, Mac or Linux box running your experiment along with any other equipment you are monitoring or triggering, e.g. MRI, EEG/ERP, eye trackers etc. Once the BBTK has automatically stepped through your whole experiment it uploads captured timing data for analysis. An API/SDK is also available should you wish to control the BBTK from your own software, e.g. Matlab, PsychoPy etc. The API supports the serial protocol over USB for PC, Mac OS X, Linux etc. and is accessed via a standard COM port.

Digital Stimulus Capture And Response (DSCAR) module timing characteristics
Various validation timing tests have been carried out at all stages of development. Initially these have focused on the Digital Stimulus Capture And Response (DSCAR) module of the BBTK and associated ARM firmware. Timing measures presented are round trip times. That is, the time taken to detect a stimulus and generate a response to it. It should be noted that timings are affected by how appropriately sensor activation thresholds are set and the quality of the equipment presenting the stimulus.

Black Box ToolKit version 1
Please note the Black Box ToolKit version 1 is now no longer for sale and has been replaced by the new ARM based version 2. The version 1 is now considered end of life and the information below is provided for legacy reasons.
All version 1 BBTK purchased within the last 12 months remain in warranty and are fully supported.

Updated version of the Black Box ToolKit version 1 software suite
An update to the current version 1 CD is available for download. You should download and install this if the date of your "menu.exe" is older than 05-10-2004 (dd-mm-yyyy). Check this by selecting "Help | About" from the toolkit main menu.
Note: You will need to email us (email@example.com) and ask for a password before you will be able to install. You are advised to uninstall any existing versions and backup your data files before installing this update. This download requires that you are an existing customer.
Black Box ToolKit version 1 hardware requirements
The Black Box Toolkit gives you the option of two installation types. The first is "Test & Analyse" and the second "Analyse Only". Test & Analyse allows you to test your own paradigms and has higher hardware requirements. Whereas analyse only allows you to analyse data already collected. In this case the minimum hardware requirements are lower.
Before you are able to test paradigms the Black Box Toolkit will run tests to calibrate itself to ensure that your host PC is capable of real time measurement. Most PCs will enable a sampling rate of 48 kHz or higher (48 samples per millisecond).
Test & analyse hardware requirements
- 1 GHz CPU or higher
- Windows 2000 or XP
- 256 MB RAM
- 100 MB Hard Drive Space (plus additional space to store real time logs - approximately 1 MB per second of run-time)
- EPP 1.7 or 1.9 or Bi-directional parallel port
- When using the opto-detectors you are advised to work in a room illuminated by natural lighting. Artificial fluorescent lighting for example can inadvertently activate the sensitive opto-detectors. Typically this will appear as mains frequency hum when you analyse your data (regular spaced peaks at 50/60 Hz). Indirect artificial lighting is generally suitable or as an alternative mask out the back of the polycarbonate opto-detector with opaque tape.
General specifications of the Black Box Toolkit version 1
- 8 channel - 4 digital input/4 digital output
- 2 opto-detector leads for detecting screen events on a second PC, Mac or Linux system
- 2 switch closure channels for simulating button presses on equipment running your paradigm
- 2 powered digital-in channels for BBTK microphones etc.
- 2 powered digital-out channels for BBTK tone generators etc.
- Fully modular so that additional custom sensors can be added
- Opto-isolated switch closure lines
- Sampling rates of over 48 kHz using a standard PC
- EPP 1.7 or 1.9 or Bi-directional parallel port interface to host PC
- Powered by external 5 V supply
- 12 month warranty
Sensor and generation modules timing specifications
The timing tests were carried out using a digital oscilloscope and our own specialized microphones and tone generators together with the standard software suite. Testing was carried out using a 1.3 GHz AMD Athlon based computer with EPP 1.9 port.

Individual line specifications
Lines 1 & 2, powered digital in & passive switch closure
TTL input. A TTL signal (0-5 V) can be connected to these lines, with ground connected to the 3.5 mm jack plug sleeve (0 V) and the signal to the jack plug ring (input signal). Device switch connections (eg. Joystick, mice etc.), can also be connected across these points as long as the polarity of any voltage across the switch is noted and this voltage doesn't exceed 5 V. Power can be taken from the 5 V on the tip of the jack plug as long as the consumption is limited to 50 mA.
3.5mm stereo jack socket. Connection as detailed below:
- Tip: 5V (< 50 mA)
- Ring: TTL signal
- Screen: 0V
The audio detection module (microphone) can be connected to these lines.
Lines 3 & 4, Opto-detector
These 2 lines are intended only for the opto-detectors provided with this kit and provide a connection from the amplifier within the Black Box Toolkit to their photo diodes.
Lines 5 & 6, powered digital out
TTL output. The signal between the ring and sleeve of the 3.5 mm stereo jack socket is TTL (0-5 V) and can be used to connect to any peripheral with an input expecting a TTL signal. Power can be taken from the 5 V on the tip of the jack plug as long as the consumption is limited to 50 mA.
Lines 7 & 8, Active Switch Closure
The 2.5mm mono sockets connect to the switch contacts of a solid-state relay. The maximum ratings for which are:
- Load voltage (peak AC): 50 V
- Continuous load current: 0.13 A
- Peak load current: 0.4 A (100 ms, 1 shot, DC)
- On resistance: 18 Ω
The connections from the active switch closure lines can be connected in parallel with device buttons (eg. Joysticks, mice, etc.) to emulate the pressing of the button. The unit is supplied with 2 flying leads with 2.5 mm connectors for this purpose.
NOTE: Be careful when connecting the flying leads from the 'Active Switch Closure' not to connect the two leads across the power supply to the device you're measuring!
- 2.5 mm mono jack socket
- Tip:Solid-state relay contacts
- Screen:Solid-state relay contacts
The power adaptor for the unit needs to be regulated and supply 9 V with a power rating of at least 250 mA. The connector for the supply is a 2.1 mm low power connector where the centre pin is 9 V and the outer being ground (0 V).
The UK version is supplied with a suitable power adaptor with a multi plug connector. The larger (2.1mm) connector is the one to use.
Response box (optional)
The response box comes supplied with an 8 way cable with flying leads. These can be connected to external peripherals as described in the 'Active Switch Closure' section. The flying leads are connected in pairs to solid-state relays within the response box, the wiring is described in the table below:
|Green – Yellow
|Orange – Red
|Brown – Blue
|Purple – Grey
