Martin,
If you desire to display all the race information using a computer and monitor, then I highly recommend getting at least one set that comes with the Control Unit. You can still do this with the Black Box but will need to buy the Black Box lap counter. Also, the Control Unit has a lot of cool accessories that you may be interested in such as the Position Tower, Driver Display and Startlight.
Best regards,
Brian
