I'm sure the Ecos is a great piece of kit. However when ever I look for information on their sites I find there is a lack of information - in English. This has been constant for the last 8 years or so. ESU simply don't translate every document, or only partly publish documentation in English. A simple look though the documentation for loksound decoders will confirm this. Great kit rubbish documentation, and in my view poor support. I find this surprising when their largest export market is the USA.
