When viewing NMEA 2000 data you must use the following:

• A. Gateway
• B. Battery monitor
• C. GPS receiver
• D. AIS transceiver

Answer: (A)

Viewing NMEA 2000 data hinges on bridging the CAN-based network to a display or computer. A gateway serves as this bridge by translating NMEA 2000 PGNs into a format that viewing software or devices can understand (such as NMEA 0183, Ethernet, or USB). Without a gateway, the raw CAN traffic on the NMEA 2000 backbone is not readable by standard displays or PC software. The other items—battery monitor, GPS receiver, AIS transceiver—are devices on the network that can generate or use data, but they do not by themselves provide the viewing/translation capability. A gateway is what enables you to actually view and log the NMEA 2000 data on a screen or computer.
