A chassis ground is a link between different metallic parts of a machine to ensure an electrical connection between them. [1] Examples include electronic instruments and motor vehicles. Usages
Common Chassis Ground – isolation between circuit common and chassis (chassis grounded). Isolated Circuit Common – isolation between circuit common and chassis (chassis floating). Isolation measurements are made with the assembly or subsystem unpowered and disconnected from any support equipment.
The use of the term ground (or earth) is so common in electrical and electronics applications that circuits in portable electronic devices, such as cell phones and media players, as well as circuits in vehicles, may be spoken of as having a "ground" or chassis ground connection without any actual connection to the Earth, despite "common" being ...
For ALDL connections, pin 9 is the data stream, pins 4 and 5 are ground, and pin 16 is the battery voltage. ... Chassis ground: 12 Manufacturer discretion.
Electrical equipment may be designed with a floating ground for one of several reasons. One is safety. For example, a low-voltage DC power supply, such as a mobile phone charger, is connected to the mains through a transformer of one type or another, and there is no direct electrical connection between the current return path on the low-voltage side and physical ground (earth).

The role “ground” may be ambiguous in systems that isolate different kinds of grounds (typical isolated grounds are analog signal ground, digital signal ground, AC power ground, DC power ground, and chassis ground). If different kinds of ground paths are in separate paths in a connector, the analysis should treat them as separate signals.
