Iron Planet Hobbies One of the best features of ESU decoders is RailCom! If you are interested in unleashing the power of RailCom we have the products you need. Please see our featured products in our store here: https://www.ebay.com/str/Iron-Planet-Hobbies?_trksid=p2047675.l2563 (Link opens in new window so you won't loose your place) Our SwitchPilot decoders cannot only control point mechanisms but also daylight signals. Most modern signals are equipped with LEDs. Usually the anode connections of multi-aspect signals are combined in order to reduce the number of wires. Some manufacturers (e.g.: Viessmann®) combine the cathodes and for that reason these signals could not be controlled with the SwitchPilot in the past. Our new adapter provides the solution. Simply plug the adapter into the output terminals of the SwitchPilot and you are ready to go. We are an authorized ESU dealer.Thanks For Looking!
