Bob,
is the DCS WiFi companion something you did on your own, or is it sponsored by MTH.
I am the sole author of the book.
MTH is the distributor of The DCS Wifi Companion's eBook version, which is the only version available at present, as well the distributor for my first book, The DCS Companion, now in its 3rd edition.
MTH also provides the services of an outstanding graphic artist who assists me with the book's composition, formatting and appearance. Other contributors are my daughter, Stacey MacMillan, who is an excellent proofreader (and also a published writer herself), and fellow DCS beta testers Marty Fitzhenry and Jim Osborne, who provided a technical review of the book.
The downloaded DCS WiFi manual is incomplete, in my opinion,
The original documentation that MTH provides is adequate for learning and using DCS via the DCS Remote, and the documentation available for the WiFi system's WIU hardware is all that's necessary to install and configure the WIU.
Documentation for the DCS App is pretty much on a par with what's available for most smart phone and tablet apps of a similar price point. If you were to compare the DCS App's documentation to the available documentation for the competition's WiFi app, you would find that this is the case.
and I wonder why we are expected to pay for a complete manual such as yours.
You are under no obligation to purchase any other documentation, authored by myself or anyone else, to use the DCS Application, or for that matter, DCS via the remote. However, consider my books to be a method whereby one can go beyond what's normally documented in order to have the best DCS experience possible.
Further, if you were to add together the cost of the DCS Application's Premium version ($24.95) and the cost of The DCS WiFi Companion eBook ($13.95), the total of $38.90 is less than the cost of the competitor's WiFi app alone, which is $49.95.
The decision regarding whether or not to purchase either of my books is a personal one, not something that one has to do.
