Downlink

The Downlink socket found on every single DUELink module is used to connect to the next Uplink socket on the next module. The DUELink software magically handles the data going across the entire Daisylink chain of connected modules.

There will be no signal degradation along the wires as data is repeated on every Downlink socket. In cases power is dropping after several modules, a Power Inject module can be used.

Wireless hook

This is not necessary in most modules as they are very low power. However, some modules, like large displays and motor drivers, do require a decent amount of power.
