DCS is a system for controlling your entire layout — multiple sound-equipped engines, switches, and accessories — from one or more wireless handheld controllers. 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 Track Interface Unit or TIU has an assortment of input features allowing the operator to link up to two AC or DC transformers, add additional AC transformers, program new software features, serial interface (RS-232), USB Port (Rev. L Versions Only) AUX power, Proto-Cast audio, AIU input, and Proto-Dispatch. The TIU also comes equipped with 4 output channels, one set for constant-voltage DCS command power, and one for conventional DCS command power. Together, the wireless handheld remote and the track interface unit, offer operators simply the best way to run their model railroad.
