User Manual

As stated before your new Rev L TIU is very much the same in terms of operation as any other TIU, just with some improvements. You will find
operating it is no different than what you are already used to.
1. Connect the TIU to your layout per the instruction manual provided with your TIU.
2. If you need to configure the TIU’s address please do so at this time. It is recommended that you do not have any other TIU powered up while
you adjust the TIU’s address so as not to conflict with another TIU.
3. Run your TIU with your DCS Remote just like you are used to doing. If this is your first DCS system, please read through the manual to
familiarize yourself with the core features and functions of the DCS system. Have fun!!!!
Operational Characteristics
For those experienced users that are familiar with how the TIU’s operate you may notice some signaling differences that you may need to account
for.
1. Connect your TIU to your layout.
2. Run a track signal test. You may notice that certain areas are worse than they were with your previous rev TIU. This is usually because the
light bulbs used to improve track signaling aren’t needed with the new Rev L TIU. Start by removing them one at a time form the suspect
sections of your track.
3. The rev L TIU has shown to provide an improvement in track signaling in most layouts. Many layouts have been altered to accommodate the
older TIU’s. In many cases none of this needs to be changed. However, in some cases the addition of the Rev L TIU may require some tweaks to
certain areas of your layout. The reason is that the new communications processor in the TIU is much more sensitive to what the engine sends
back.
4. In some instances actually adding a little bit of load to the track helps with the new Rev L TIU. For example, if you have a smaller layout and
have a section that has only 10ft of wire to the track, you may find that adding another 10ft of wire makes the signal actually better.
If you are having problems with your TIU please contact an Authorized MTH Service Center or M.T.H. Electric Trains directly.
