3. Installation
To complete this project, you will need to connect a 12 to 16 Volt (AC or DC)
transformer to the terminal J1 (see Figure 2 for the location of J1). If you intend
to power 1WIO relay units from the 12V output of 1WSwitch, the transformer
needs to supply at least 350mA (250mA for 1WIO and 100mA for 1WSwitch) per
1WIO relay unit, up to a maximum of 800mA, or 2 1WIO relay units. Beyond
that, supplemental powering will need to be provided for the off-board units.
Otherwise, any 12 to 16 Volt adapter capable of at least 100mA will do.
If you are using a sensor network of 1-Wire devices, connect them now to either
connector J3 or J5.
