| 13 | Logic analyzer setup |
| 14 | -------------------- |
| 15 | |
| 16 | The logic analyzer used was a Dreamsoucelab DSLogic Plus at a sample rate of |
| 17 | 100MHz. |
| 18 | |
| 19 | The hardware used for generating the communication was an Intrepid FlexRay |
| 20 | Evaluation Board. |
| 21 | FlexFray controller: Fujitsu MB88121C (Bosch E-Ray IP) |
| 22 | Bus Transceiver: Elmos E910.54B |
| 23 | |
| 24 | Product info: |
| 25 | https://store.intrepidcs.com/FlexRay-EVB-p/flexray-evb.htm |
| 26 | |
| 27 | The software used was Intrepid Vehicle Spy for FlexRay running under Windows 7. |
| 28 | The data has been generated by using software version is 3.5.0.19, neoVI DLL |
| 29 | version is 3.5.1.29. |
| 30 | |
| 31 | The software and hardware are end of life products and are not available |
| 32 | anymore by the manufacturer. |
| 33 | |
| 34 | The logic analyzer probes were hooked up to the RX pins of the Elmos E910.53B |
| 35 | logic level transceivers. Channel 0 was hooked up to FlexRay channel A and |
| 36 | channel 1 was hooked up to FlexRay channel B. Channel A and B of both FlexRay |
| 37 | controllers are connected together. |
| 38 | |
| 39 | The bus was externally terminated by adding a 100 Ohm resistor between FR_A+ |
| 40 | and FR_A- and another 100 Ohm resistor between FR_B+ and FR_B-. |
