Multiple Domes means that more than one fast dome is linked in the system. Each dome connects to
next dome forming a serial linking. Each dome has an individual ID dip switch, which allows the keyboard
to identify each fast dome and make command. Sometimes it is more convenient to wire a telemetry
system in star configuration rather than daisy chain. To do this a PIH III data distributor is necessary. It
takes an output from a keyboard or a matrix and splits the single data line into 4 separate data lines. One
keyboard can control up to 64 cameras.
