Speed Inter­face

The ADIF (=“ADvanced InterFace“) is a CAN bus interface that reads signals from the CAN bus of vehicles and outputs them in analog form.

The ADIFs are vehicle-specific adapters. In contrast to universal adapters, these products are particularly accurate in the output of values.

Fields of application of the ADIFs:
The standard version has a wide range of possible applications, such as retrofitting radio and sound systems, telematics solutions and radios.
With KA versions, the speed is generated loss-free from the information of the wheel sensor. This interface is therefore mainly used for taximeters or odometers.
The ZI version provides information about the engine running and can therefore be used to connect additional instruments (driving school or driver training), additional batteries or comparable devices.
