There are various types of connection through which electronic devices transmit and receive data. Such connection is usually facilitated by a particular type of data channel, also referred to as electronic bus. In most electronic devices that are used in industrial facilities and machineries, such electronic bus is called CAN—the abbreviated form of controller area network—bus. CAN bus is designed to allow microcontrollers and electronic devices installed on a vehicle or machinery to communicate with one another. The dual-wire channel of the controller area network allows vehicle’s electronics to use a simplified wire instead of complicated cable loom.
Because CAN bus facilitates communication between electronic devices and microcontrollers, which are in fact small computers, there must be a way to connect a CAN bus to a computer. Because a connection between a computer and any external hardware devices is usually facilitated by the computer’s universal serial bus (USB), there should be a way to establish connection between the computer’s USB and the CAN bus. In order to enable such connection, a USB to CAN adapter is needed. This adapter is now available at most computer’s stores and stores that sell electronic devices for vehicles, machineries and heavy equipment.
There is a very obvious reason why a connection between a computer or laptop and the CAN bus of a vehicle or machinery is necessary. Remember that many components of a car are operated by computer. Components like the car’s ECU and mirror adjustment system are all components that are operated by computerized mechanism. If a mechanic or a car owner wants to diagnose any problems that prevent those components to work properly, a connection with an external computer is necessary. By using this adapter, such connection can be established and those shortcomings can easily be diagnosed and taken care of.
