FAQ

How long can I extend the 1-wire cable to install inside a cabin?

The 1-wire cable from the Syrus to the input/output expander can be extended up to 20 meters.  Make sure you use the same cable gauge or a thicker gauge when extending this cable.  Consider using a twisted cable like UTP CAT5e.
