19 | | 1. Mount the CM-MMCX modules on each WARP v3 node. Power must be '''off''' when mounting/unmounting a clock module. |
20 | | 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. |
21 | | 1. Connect MMCX cables from the outputs of the source node to the inputs of the sink node. |
22 | | 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). |
| 23 | 1. Mount the CM-MMCX or CM-PLL modules on each WARP v3 node. Power must be '''off''' when mounting/unmounting a clock module. |
| 24 | 1. Set the CM-MMCX or CM-PLL switches on each node (see [wiki:../../HardwareConfiguration/WARPv3#ClockConfiguration Clock Configuration settings]); one node will be the clock source, the other will be the clock sink. |
| 25 | 1. Connect clock modules: |
| 26 | a. If using the CM-MMCX modules, connect MMCX cables from the outputs of the source node to the inputs of the sink node. Then, 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 [http://warpproject.org/trac/attachment/wiki/WARPLab/Examples/8x2Array/8x2_diagram.png this figure]; note that this example does not require FMC-RF-2X245 modules). |
| 27 | b. If using the CM-PLL modules, connect the cable between the Board-to-board Header Out of the source node and the Board-to-board Header In of the sink node. |
