| 2 | NMEA 2000 / CAN traffic (fuel flow sensor and GPS receiver) | |
| 3 | ------------------------------------------------------------------------------- | |
| 4 | ||
| 5 | This is a set of example captures of the CAN / NMEA 2000 signals via an | |
| 6 | SK Pang CAN bus breakout board (using a Microchip MCP2551 transceiver). | |
| 7 | ||
| 8 | The data contains CAN / NMEA 2000 sample frames at 250kbps, the NMEA 2000 | |
| 9 | bus/network has the following equipment connected: | |
| 10 | ||
| 11 | - Lowrance EP 60R (fuel flow sensor) | |
| 12 | - Garmin GPS 17x NMEA 2000 (GPS receiver / antenna) | |
| 13 | ||
| 14 | The signal grabbed is the (digital) CAN_RX pin of the MCP2551 chip. | |
