> ***Note:*** This tutorial follow a configuration with two [SPEC+FMCDIO] boards connected in the two **PCIe x16** interfaces of the same computer. However, you can also use two different computers (if you do not have two **PCIe x4**) and follow this tutorial; you just need to replace all the commands with `wr1` or `0x0300` by the `wr0` and its corresponding bus_id on the second PC. The configuration with two separated PCs is more *"natural"* to understand how to communicate two different nodes using the starting kit,
but it requires more physical space to implement it.
