| 5 | These captures are artifically generated CAN-FD messages and are not capturing | |

| 12 | Logic analyzer setup | |
| 13 | -------------------- | |
| 14 | ||
| 15 | The logic analyzer used was a Dreamsoucelab DSLogic Plus. | |
| 16 | ||
| 17 | Channel 0 was hooked up to a PEAK-PCAN-USB Pro CAN-FD device which has two | |
| 18 | CAN ports. Both ports were connected together using a selfmade circuit board. | |
| 19 | ||
| 20 | The bus was externally terminated by adding a 120 Ohm resistor between CAN_L | |
| 21 | and CAN_H. | |
| 22 | ||
| 23 | The data has been generated using PEAK PCAN-View v4.2.1.533 software running | |
| 24 | under Windows 7. Firmware on PCAN-USB Pro was v3.2.0. Driver version was 4.1.4. | |
| 25 | Both ports were opened by running two instances of the software. One for each | |
| 26 | port. All ACKs were handled by the participants. | |
