MTH - 50-1039 WTIU Wi-Fi Track Interface Unit

DCS is a system for controlling your entire layout —
multiple sound-equipped engines, switches, and accessories —
from one or more smart devices with the DCS App installed. DCS is
compatible with all M.T.H. Proto-Sound 2.0- or 3.0- equipped
locomotives. In O gauge, it is also compatible with locomotives
equipped with Lionel® TMCC® and Legacy™, as
well as conventional AC-powered engines.

The full DCS Digital Command System is an all-encompasing
network of components that brings true interactive wireless control to
a model railroad. Users utilize their own smart device — iOS
or Android — and an intutive app to run multiple tracks,
hundreds of trains and control switches and accessories. Bi-directional
communication between locomotives and the system’s WTIU WiFi
Track Interface Unit makes adding and programming locomotives simple
and easy. No more ID numbers to remember and no complex icons to
decipher. It’s fast, it’s easy and it’s
fun!

The all-new WTIU combines a wifi module and a track interface
unit into one unit. Featuring four channels, the new WTIU can now
control conventional DC locomotives by varying DC power to the track,
allowing the user to control command and non-command equipped
locomotives on the same track at the same time. The WTIU sets up in
seconds and doesn’t require a home WiFi system to operate. It
can control accessories and switches when connected to the separately
sold AIU Accessory Interface Unit and can receive commands from an
unlimited number of smart devices.
