Overlay 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 Bootup
The device self-calibrates upon every bootup and is not adjustable in the player hardware or software.
BrightSign button pad units are not “hotplug-able” 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 firmware, 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.
