You might wonder what ties all of these devices together in an organized fashion. There are two ways this can be accomplished individually or in combination, wired and wireless.
Wired: each device is connected to the controller or sub system through a physical connection to communicate analogue or digital signals. This physical connection communicates the requirements of each device and indicates to the controller what to do next.
Wireless: each device is connected to the controller or sub system wirelessly using wireless transmitters, receivers and repeaters to communicate. This wireless connection communicates the requirements of each device and indicates to the controller what to do next.
Each system requires many different kinds of cable in every situation. These cables have to be terminated at a common location in cabinets, on racks, on equipment, patch panels at the equipment end. Some of the cables have to be terminated on modules and installed in boxes and frames at the peripheral end. With a structured wiring system which is the back bone of your control system is easily modified and professionally done.
