Conventional, Command, or Both
If you plan to run trains in conventional and command mode on the track at the same time you
will need to use a Variable channel of the TIU. Using the Variable channel of the TIU, you can
run conventional engines (vary the voltage to the track) and command engines (send digital
commands) on the track at the same time to vary the speed of the engine for example. It is
important to remember that the top speed of the command train will be limited to the voltage
on the track.
NOTE:
The variable channels require 22 volts AC power at the Variable Input to provide the
voltage displayed on the DCS Remote. If less than 22 Volts AC is provided to the Variable
Input the voltage output to the track will be less than that displayed in the DCS Remote. The
TIU Variable Channel will NOT vary DC power.
Using DC Power Supplies
It is important to remember the DCS system was designed for inside layouts. If DCS is used
outdoors on One gauge or (G gauge) layouts, please make sure the system is protected from
the weather (rain and snow for example). In addition, DC power will NOT pass through the
TIU Variable Channels. Therefore, use only the Fixed 1 & 2 Channels with DC power sup-
plies. Also remember the polarity is critical to DCS Command operation. The positive (+) rail
carries the digital signal. You may have to place the engine on the track in the opposite direc-
tion if the engine does not have a polarity switch. It is also very important to keep in mind
the positive output (+) from the DC power supply must be connected to the positive (+) input
terminal on the TIU Fixed channel to carry the DCS signal to the track.
