The DerbyLink system was put to the test last weekend - powering the Micro Wizard finish gate, converting RS-232 to RS-422, then RS-422 to USB, and simplifying the wiring down to a single lowly CAT5 cable. A complete success and nothing out of the ordinary to report during the pinewood derby of Cub Scout Pack 45 of Farmington, Michigan. I really like the whole PoE power setup, and I think I'll use it again in any projects that require cabling and power and perhaps not being convenient to an AC outlet.
