    v10 v11  
    77This example uses 3 nodes:
    88 * A node that acts as a primary transmitter. This node uses its own on-board clocks for sampling and RF clocking.
    9  * A node that acts as a secondary transmitter. This node the primary transmitter's clocks as the sources for sampling and RF. Furthermore, the [wiki:.../Reference/TriggerManager Trigger Manager]
     9 * A node that acts as a secondary transmitter. This node the primary transmitter's clocks as the sources for sampling and RF. Furthermore, the [wiki:../../Reference/TriggerManager Trigger Manager] core is used such that the secondary transmitter is triggered by an external twisted pair cable assembly.
     10 * A node to act as a receiver.

    1923To 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.
     24 1. Mount the CM-MMCX modules on two WARP v3 nodes. Power must be '''off''' when mounting/unmounting a clock module.
     25 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].
     26 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.
    2227 1. Connect MMCX cables from the outputs of the source node to the inputs of the sink node.
    2328 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).
    2429 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
     30 1. Power on the two WARP v3 nodes
    2631 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".
     32 1. Power
