Saleem,
1- Mfr. Part Number: DR-5762064 is the part number for wall brackets for use with our new model ActivBoards and are not compatible with the ActivBoards you have listed. We are unable to provide the part number for the wall brackets you require as the part numbers we use for warranty replacements and part numbers used by our vendors generally do not match. Any one of our vendors will be able to assist if they have these brackets in stock. Our vendors are located at www.prometheanworld.com, select Education/ How to Buy.
2- The ActivHub will work with certain model slates. There is an article on our knowledge base that will guide you on which model slate works with the 2.4Ghz ActivHub. Please visit www.prometheankb.com, select your region/language, in the search box type in 10666- the title of the article is: ActivSlate Which ActivHub does my ActivSlate require?
3-Yes, when you select the Support tab/ Download ActivInspire, you will select I have an ActivExpression, Activote, ActivBoard (excluding 100,300 &500) and follow the instructions there to produce an ActivInspire Professional software serial number.
Thanks!
