Multiplexing



Multiplexing Made Easy

What is Multiplexing?

All multiplex systems consist of a Bus network which communicates between components of the network, some form of input device which translates events such as a button press into a serial network message which is then transmitted to the logical controller, in this case a load controller in the system. Digital Switching Systems’ Load Controller combines both the logical features of the system with the actual switching of power. Using solid state technology and electronic messaging enables load control features such as remote resetting of trip circuits; this provides the capability of mounting the load controller close to the power source and output devices.
 

Advantages of Multiplexing

The value of multiplexing comes primarily with the replacement of discrete switching. This requires that each device be connected to the power source through the switch located at the dash. Each device, no matter where it is located must be wired from the battery, to the switch on the panel, and finally to the device. A multiplex system allows connections between the battery, the load controller located near the battery, and the device and the keypad is mounted at the dash without physical connection to the device. The most visible improvement with a multiplex system can be demonstrated by taking a look at the ‘dark side’ of the dash.
