Steps
Wire the gateway (e.g. YDWG-02 WiFi, YDNU-02 USB) onto the NMEA 2000/SeaTalkNG/SimNet backbone
Connect to the gateway's built-in admin web server to configure one or more NMEA Data Servers, each independently set to TCP or UDP transport
For widest app compatibility, configure a server with the NMEA 0183 protocol output
For full raw access including manufacturer-proprietary PGNs, configure a server with the RAW protocol and consult the exact wire-format appendix in that specific product's PDF manual
Use the free CAN Log Viewer utility to monitor traffic live or record to a .CAN file, converting recordings with the YDVR Converter tool for GPX/CSV analysis
Apply per-server message filters to control which PGNs/sentences are forwarded to each connected client
Known gotchas
The RAW protocol's exact wire format is documented only inside each device model's PDF manual appendix, and formats can differ subtly between RAW Mode and N2K Mode across models
UDP servers allow unlimited simultaneous clients while TCP is connection-limited, which materially affects how many apps can consume the stream concurrently
The gateway passes through proprietary PGNs from other manufacturers (e.g. CZone) without decoding them; it bridges protocols but does not interpret vendor-proprietary content
