 == Setup ==

+NOTE:  Setup is shown for CM-MMCX modules since that setup is more complicated.  If using the CM-PLL module, attach the CM-PLL cable from the '''OUT''' header from the primary transmitter to the '''IN''' header of the secondary transmitter.

 To run this example, you must set up your experiment as follows:
- 1. Mount the CM-MMCX modules on two WARP v3 nodes. Power must be '''off''' when mounting/unmounting a clock module.
+ 1. Mount the CM-MMCX or CM-PLL modules on each WARP v3 node. Power must be '''off''' when mounting/unmounting a clock module.
  1. Mount the FMC-RF-2X245 modules on the same two WARP v3 nodes. For assistance installing an FMC-RF-2X245, see the [wiki:GettingStarted/WARPv3/Hardware#InstallinganFMCModule FMC Installation How-To].
- 1. Set the CM-MMCX switches on each node (see figures below); one node will be the clock source, the other will be the clock sink.
- 1. Connect MMCX cables from the outputs of the source node to the inputs of the sink node.
- 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).
+ 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.
+ 1. Connect clock modules:
+   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 figure below).
+   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.
  1. Set the DIP switches on the WARP v3 boards to 0000 (clock source node) and 0001 (clock sink node).

  1. Set the DIP switch on the third WARP v3 board to 0010.
  1. Power on the third WARP v3 board and download the 2RF WARPLab reference bitstream. The node should boot and show "03" on the hex displays.
