| 19 | To run this example, you must setup your experiment as follows: |
| 20 | 1. Mount the CM-MMCX modules on each WARP v3 node. Power must be '''off''' when mounting/unmounting a clock module. |
| 21 | 1. Set the CM-MMCX switches on each node (see figure below); one node will be the clock source, the other will be the clock sink. |
| 22 | 1. Connect MMCX cables from the outputs of the source node to the inputs of the sink node. |
| 23 | 1. Connect the twisted pair cable between the debug headers of the WARP v3 boards. Pin 8 of the source node should connect to pin 15 of the sink node. Use the other conductor of the cable to connect ground between nodes (see figure below). |
| 24 | 1. Set the DIP switches on the WARP v3 boards to 0000 (source node) and 0001 (sink node). |
| 25 | 1. Power on the WARP v3 nodes |
| 26 | 1. Download the WARPLab reference bitstream to both nodes (source node first). Both nodes should boot, with the source node showing "01" on the hex displays and the sink showing "02". |
