Which statement best describes device instancing when installing multiple identical devices on a NMEA 2000 network?

• A. 1 Transducer
• B. 3 Transducers
• C. No Transducers
• D. 2 Transducers

Answer: (D)

Device instancing lets you place several identical devices on one NMEA 2000 network by giving each device a unique instance number. When you have more than one of the same device, you assign different instances to each one so they can be addressed separately. In practice, if you install two identical transducers, you configure two distinct instances—one for each transducer—so the network sees two separate devices. This is why the scenario is described as having two transducers on the network, each with its own instance.
