Overview
The ALIARO Powering Switching Chassis (AL-1020U) provides the power and bus network
switching used in a vehicle while also providing the ability to individually enable or bypass bus
signals to each ECU.
The AL-1020U is made to fit National Instruments (NI) Switch Load Signal Conditioning (SLSC)
system together with corresponding computer interface boards. Software control is achieved
through a Python library, pre-delivered by Aliaro.
