DCS WiFi
Digital Command System
User’s Guide

Welcome to the world of digital command control! M.T.H. Electric Trains® has developed the
most advanced and user-friendly layout control system available in model railroading today.
The Digital Command System (DCS) allows you to achieve realistic operation heretofore
unknown in the hobby. DCS was designed so that even the most advanced operations can be
performed easily, so you can quickly begin to enjoy the hobby at a whole new level.
With DCS you can control every command-capable locomotive on your layout, including
TMCC locomotives, independently. For Proto-Sound® 2.0 locomotives, you can adjust light-
ing, chuff rate or diesel rev level, sound and smoke volume for each locomotive; dial up a
specic scale speed; program multiple-headed locomotives to act as one; record and playback
an operational script; and much, much more.
These operating instructions include Quick-Connect instructions that tell you how to set up a
loop of track quickly and get running right away, so you can gain the benet of DCS command
features as soon as possible. The Quick-Connect section is followed by more advanced con-
nection and operation information.

CAUTION: ELECTRICALLY OPERATED PRODUCT:
Recommended for Ages 14 and up. Not recommended for children under 14 years of age without
adult supervision. As with all electric products, precautions should be observed during handling and
use to prevent electric shock.
WARNING: When using electrical products, basic safety precautions should be observed, including
the following:
- Read this manual thoroughly before using this device.
- M.T.H. recommends that all users and persons supervising use examine the hobby transformer
and other electronic equipment periodically for conditions that may result in the risk of re,
electric shock, or injury to persons, such as damage to the primary cord, plug blades, housing,
output jacks or other parts. In the event such conditions exist, the train set should not be used until
properly repaired.
- Do not operate your layout unattended. Obstructed accessories or stalled trains may overheat,
resulting in damage to your layout.

Introduction To DCS
The Track Interface Unit
Also known as the TIU, the Track Interface Unit is the brains behind the DCS system. Con-
nected between the transformer and the track, the TIU receives signals from the DCSApplica-
tion and relays those signals to each train you are controlling via the rails. The type of signal
relayed to the train depends on the operating mode at the time. If operating conventionally, the
TIU will raise and lower track voltage to control engine speed. If operating in command mode,
the TIU will send a digital signal to each train you are controlling via the track rails.
This digital signal is very powerful and contains a lot of information much like the digital sig-
nals used in today’s high tech products. These digital signals are what allow DCS to perform
the hundreds of functions designed into the system.
ATTENTION
TIU contains internal fuses.
If there is no output,
open the case (6 screws)
and check the fuse.

Introduction To DCS
The Accessory Interface Unit
The Accessory Interface Unit, also known as the AIU, plugs into the TIU and controls any
accessory or switch wired to it. Each AIU can control up to 10 switches and 10 accessories and
features the ability to turn the accessory on or off, or activate it momentarily.
The AIU essentially acts as a large relay and simply replaces the manual switches that are
normally used to turn on and off model railroading accessories. Connection to the TIU is done
through a special cable (included with the AIU) and up to ve AIUs can be daisy-chained to
one TIU.
ATTENTION: Connecting the TIU to theAIU output may cause damage to earlier
model AIU’s

Introduction To DCS
Recommended Wiring Method
It is important for good operation to make the most efcient use of the power and digital sig-
nal available on your track. Poor wiring and bad connections offer resistance and can interfere
with receipt of the DCS signal and limit the number of engines and cars you can run on your
track. Be sure to use proper wire (we recommend 16-gauge or larger paired wire, like speaker
wire) and good connections (good connections mean crimp or solder).
Because center rail blackening is not conductive, you may nd that the blackening on your
track creates resistance that drains power and signal. If so, use Scotch-Brite®, ne-grit sand-
paper, or an LGB® track cleaning block to clean the blackening off the top of your center rail.
Advanced wiring information and diagrams, including wiring for layouts using blocks for
conventional operation, are located in the “Universal Locomotive and Accessory Operation”
section of this manual.
Optimal Performance Wiring Principles:
- Use 16-gauge or larger paired wire (such as speaker wire)
- Use a star pattern (home run wiring) to wire directly from the TIU to each lock-on
- Use a terminal block to carry power and signal from one TIU channel to multiple lock-
ons
- Avoid common bus wiring
- Solder for tight connections (not required)
- Clean the blackening off the top of the center rail (if necessary)
- Power accessories and turnouts via auxiliary, not track, power
- Place a lock-on (or wire directly to track) approximately every 25 linear feet, both
center and one outside rail

NOTE: This very quick wiring scheme (through the Fixed In 1 and Fixed Out 1 inputs) al-
lows for operation of the connected loop of track in DCS command mode only. Please see the
“Advanced Connection” section of this manual in the “Universal Operation” chapter for all the
wiring options if you have more complex wiring and operational needs, including conven-
tional mode and TMCC operation.
