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-804 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 camera.

Fast Dome, Matrix and Keyboard
Matrix System is designed to process multiple video systems and video switching.
Its central process unit (CPU) can manage multiple video signals simultaneously and control
other linking system, such as PIH-7000/7600/7625 fast dome or PIH-820 telemetry receiver.
All telemetry remote control and signal transmissions are through twisted pair One matrix can
Multiple keyboards can be used for matrix control. 1st keyboard is the master and rests are slaves. Up to 8 keyboards can be used in one system. Each keyboard has a Dip Switch for ID setting. (Please refer to keyboards manual for detail)

Fast Dome, DVR Multiplexer Video Management System and Keyboard
The DVR System is an advanced digital recording product, with long recording time and easy searching features. Telemetry remote control is twisted pair for data transmission to the fast dome. Fast Dome can be controlled directly from the control panel of the DVR, or from keyboard.
Each DVR video management system can manage 16 video signals (fast domes). Through RS-485 connection, 16LILIN stand along DVRs can be linked in one system.
