BP200 / BP900 Button Boards

the bp200 and bp900 button boards allow for interactive usb functionality button presses can be registered as events in brightsign author docid\ altwiwesam7 pgdlmu3sp or brightauthor classic docid\ nddvgthfcdsf6o7feyj0l these boards have a usb mini b connector button panel overlays if you intend to cover brightsign button boards with overlays, adhering to the following guidelines will help ensure reliable performance all applications should be thoroughly tested before broad deployment materials plastic, acrylic, polycarbonate (pc), lexan, wood and acrylonitrile butadiene styrene (abs) surfaces have all been verified to work polyester (pet) and tempered glass materials are also acceptable do not use materials that retain a static charge thickness the overlay material must be 1⁄4” or thinner if the material is too thick, the buttons will not trigger air gaps ensure there is no air gap between the overlay material and the button panel board for optimum performance, we recommend utilizing a single sheet of material, and printing or embossing your button graphics to the top surface of the overlay which eliminates the possibility of any air gaps and reduces the risk of material flexure multiple sheets of material with the graphics pressed between two sheets of lexan or abs has been done with success, but air gaps can be introduced, and the overlay thickness overall should still be 1⁄4” or thinner bonding it is strongly recommended that the button panel be permanently bonded to the overlay material to prevent any pcb board flexure/ warping that may occur over time, especially if exposed to extreme temperatures or temperature swings successful integrations have secured the overlay with screws, automotive grade non conductive rtv silicone, or 3m automotive tape adhesive button panel boot up the device self calibrates upon every boot up and is not adjustable in the player hardware or software brightsign button pad units are not “hot pluggable” therefore, they need to be connected to the brightsign player along with any overlay material including button graphics prior to applying power upon boot up, the player checks for any connected brightsign peripherals, verifies the os, and performs a calibration for the capacitive touch any changes to the overlay placement or thickness and disconnecting the button panel and reconnecting the button panel, will nullify the previous calibration
