DC Power Cabling
The control panels and the serial interface are powered by external
transformers. The transformer is either 90-130VAC or 180-260VAC
as stated in your equipment order. Check the label before
plugging the transformer in. (Note that, due to the wide variation
in styles, you must supply the 240VAC plug end.)
