The B-104 push button interface provides a convenient way of connecting remote push buttons to any of the BrightSign players which have a GPIO 15 pin connector. In this way heavy duty push buttons, such as the Museum Technology X-6000 series, are all that is seen by the public. Instead of push buttons, other activators such as the bb-200 motion sensor or the KD-1 or KD-3 proximity switches may be employed. For convenience in programming and installation testing, four illuminated push buttons are provided on the B-104. These buttons duplicate the function of the remotely mounted buttons, thus allowing the exhibit to be fully tested prior to actual installation.
