Multiplexing Solutions

One of the key benefits of ACTIA multiplexing systems is the ability to add functions without adding new hardware or decreasing reliability.

Common sensor and control data, such as vehicle speed, engine temperature, etc. are available on the network, so data can be shared, thus eliminating the need for redundant sensors.


Advantages Of Multiplexing

By reducing the wiring loom and removing the fuse boxes, relays and the associated cabling systems, cable trays, fixing system and other wiring accessories, multiplexing simplifies the vehicle's electronics, whilst at the same time allowing functionality and control that was unheard of by using 'traditional' systems.

A Modular Solution

By designing its Acti-MUX system in modular form, Actia have developed a very powerful system that can be used on a number of different types of vehicle. Modules are programmed for their use within the system and are linked using a CAN network.

The system functionality can be rapidly changed by modifying the software - often without changing or adding new hardware. This modular design makes such modifications easy to perform and reliable in use.

Multiplexing In Action

Acti-MUX is a very versatile system. It can be used on the following types of vehicle:- Buses, Coaches, Fire & Rescue, Refuse Collection, Road Sweepers, Rail Maintenance Vehicles - in fact any application requiring the effective and dynamic control or monitoring of the vehicle electrical system.

Multiplexing can control & monitor a wide range of electrical functions (removing the need for individual electronic controllers) including: External lighting, Instrument cluster, Switch panels, Message centre , Door control, Ferry lift, Internal lighting, Heating / Air con, Retarder, Wipers, Mirrors, Kneeling.


Master Units

The ‘brain’ of the electrical system,  replaces CAMU thereby reducing component requirement. Our Master Units provide continuous monitoring of its inputs and outputs for fault detection and diagnostics.
