Which type of gauge obtains signals from the ECM and can be linked together?

The type of gauge that obtains signals from the Engine Control Module (ECM) and has the capability to be linked together is known as LAN Gauges. These gauges utilize a Local Area Network (LAN) protocol to communicate with the ECM and other components within the system, enabling them to share data and operate in a synchronized fashion. This networked approach provides enhanced functionality and the ability to display comprehensive information about the performance and status of a vehicle.

By leveraging the connection with the ECM, LAN Gauges can provide real-time diagnostic data and metrics, allowing users to monitor performance more effectively. This interconnectedness enhances overall vehicle management, as multiple gauges can be configured to work collaboratively, offering a cohesive display of important data.

The other types of gauges, although used in various applications, do not share the same capabilities with respect to being networked or acquiring data directly from the ECM in the same manner. Analog Gauges typically use physical indicators to display information and are not designed for networking. Digital Gauges can show electronic readings but may not have the same networking capability as LAN Gauges. Standard Gauges usually refer to simpler, traditional displays that are not connected to an ECM network.
