Stage 1 - Running a Train

Throttle options 

There are a lot of different throttle options available to control your trains and layout, including software applications available for your smart phone or computer and physical hardware options, both wired and wireless.

Going in to any detail on the myriad of options available is well outside the scope of this exercise, so on this page we will be focusing on the four options most commonly used with EX‑CommandStation: EX‑WebThrottle, Engine Driver, wiThrottle, and JMRI.

For other throttle options, refer to the Choosing a Throttle (Controller) - Advanced page for further information on choosing a throttle, and you can also refer to the Throttles (Controllers) section for more information on the various throttle options available.

What to expect to learn from stage 1 

At the end of this stage, we expect you will have learnt the following:

How to run a train on your direct connected EX‑CommandStation with EX‑WebThrottle
How to run a train on your WiFi enabled EX‑CommandStation
How to run a train on your JMRI connected EX‑CommandStation
How to run more than one train (Individual or Consist/Multiple Units)
How to program a decoder using JMRI

Run a train using EX-WebThrottle 

If you’re just starting out with EX‑CommandStation, or have a minimal system with no WiFi or Ethernet connection options, then a great way to start simply is by using EX‑WebThrottle via your direct USB connection.

This is by far the simplest option to verify your EX‑CommandStation is set up and working correctly, as you don’t need to install any software or worry about any network connections to get your first train running on your layout.

While there is a lot more detail on the EX-WebThrottle page, we will give you a very quick start guide here to get a single train running with your EX‑CommandStation.

Firstly, launch EX-WebThrottle in your Chromium based web browser (Google Chrome, Microsoft Edge, or Opera).

Try It Now

Once you have EX‑WebThrottle opened in your browser, follow these steps to get your train running:

Ensure your EX‑CommandStation is connected to your computer via the USB cable
In the top right corner, ensure “Serial” is selected from the pull down menu, then click the Connect DCC++ EX button
A pop up window should appear, prompting you to choose your COM port
Select the COM port then click the Connect button, and the button in the top right corner should change to Disconnect DCC++ EX with a green circle to the left
Turn track power on with the Power button
Type the DCC address of your loco into the “Locomotive ID” text box, then click the > button to set it
You can now use the throttle slider or + and - buttons to set the speed, and the slider in the centre of the screen to set forward, reverse, stop, or EStop
The function buttons to the right can also be used to set the various functions supported by your decoder

Enjoy running your train!

Run a train on your WiFi enabled EX-CommandStation 

If when you assembled your EX‑CommandStation with one of the common configuration options, then you will have a WiFi enabled Command Station, which will allow to run your trains with a smart phone. We are only going to cover two common options here:

Engine Driver - For Android phones
WiThrottle - for Apple iOS phones

Engine Driver (Android)

If you have set up your EX‑CommandStation in Access Point (AP) Mode (The Recommended approach)
- Open the network settings on you phone
- Change to the network of the EX‑CommandStation
  - SSID (Network name) : ‘DCCEX_xxxxxx’
    where the x’s are the last 6 digits of your device’ MAC address (unique to each device)
  - Password: ‘PASS_xxxxxx’
    where the x’s are the last 6 digits of your device’ MAC address (same as above)
If you have set up your EX‑CommandStation in Station (STA) Mode (The alternate approach)
- open the network settings on you phone
- change to your home network
  - use your normal home id and password
Start the Engine Driver App
Go through the initial startup pages to set some basic configuration items
On the ‘Connection screen’
- You should see ‘DCCEX_xxxxxx’ (as above) in the discovered servers list
- Click on this.
  (As long as you did not change the IP address of the EX‑CommandStation when you ran EX‑Installer then this should connect
You should now be on the the ‘Throttle screen’
Turn on the power to the track via the menu
- (The three dots or bars) then ‘Power’. Then click the power button till it goes green. (May require more than one click)
- The two red LEDs, for the main track, on the Motor board will turn on
- Click Back
back on the ‘Throttle screen’
- Click one of the Select buttons
This will have taken you to the ‘Select Loco screen’
- Enter the DCC Address of the loco you put on the track
- Select Short or Long (normally if the address is less than 127, it will automatically assume it is short)
- Click Aquire
Back on the ‘Throttle screen’ you can now use the sliders to move your train.

See Engine Driver Page for details on how to install and run Engine Driver.

wiThrottle (iOS)

Note

The free version of WiThrottle (‘WiThrottle Lite’) only controls one loco at a time and does not offer turnout control or DCC track power control. (Note: EX-CommandStation can be configured to automatically turn the track power on. See the EX-RAIL examples.)

The paid version WiThrottle can control multiple locos, can create and control consists, can control turnouts and routes, and can control DCC track power.

If you have set up your EX‑CommandStation in Access Point (AP) Mode (The Recommended approach)
- Open the network settings on you phone

Run more than one train (Individual or Consist/Multiple Units)

Engine Driver (Multiple Trains)

Engine Driver can optionally show throttle screen layouts that can provide for between 1 and 6 separate throttles. Each throttle can control and unlimited number of loco as a Consist / Multiple Unit train.

Multiple Throttles

To have more than one throttle you need to select a Throttle Screen Layout that has more than one throttle on it.

Use the Throttle Screen Layout preference to select a layout that supports more than one throttle (menu ‣ Preferences ‣ Throttle Screen Appearance Preferences ‣ Throttle Screen Layout). The numbers in brackets after the Layout name are the number of throttles that the layout supports.

Where a layout supports a range of throttles, select the number that you want to show with the Number of Throttles preference (menu ‣ Preferences ‣ Throttle Screen Appearance Preferences ‣ Number of Throttles).

See the Throttle Screen Appearance Preferences page on the main Engine Driver help sites for detailed information on the options that each Throttle Screen Layout offers.

Consist / Multiple Unit train

Adding additional locos to the Consist / Multiple Unit train is identical to the process of selecting a single loco. Simply click on the Select button, which will be showing the name or address of any locos already selected.

After selecting each additional loco, the Consist Edit screen will be shown. This allows you to:

Change the facing of each loco (except the front loco)
Change the order of the locos in the Consist / Multiple Unit
Remove locos from the Consist / Multiple Unit

wiThrottle (Multiple Trains)

Note

The free version of wiThrottle (WiThrottle Lite) does not provide any options for running multiple trains or Consisted / Multiple Unit trains. You need to purchase the paid/full version.

LOW - Stage 1 - WiThrottle - Multiple Trains

Program a decoder’s DCC address 

DCC-EX provides an Android app EX‑Toolbox with a basic interface for programming DCC decoders, but it requires that you connect to the EX‑CommandStation over WiFi or Ethernet. (USB is not supported.)

There are three Android apps that can program decoders:

EX-Toolbox can program decoders over WiFi or Ethernet.
Engine Driver can program decoders over WiFi or Ethernet.
RtDrive Dcc++ can program decoders but it is not particularly user friendly to do so.

We also recommend using JMRI DecoderPro for programming decoders. It works for USB connected a EX‑CommandStation and it provides plain English descriptions of all the CVs of a huge number of different decoders, is very well supported, runs on the major PC operating systems, and is free and open source.

Programming options 

There are two basic methods for programming decoders

Using the Programming Track (Service Mode programming)
Programming on Main (POM or Ops Mode programming)

Programming on the programming track, or service mode programming, allows for receiving acknowledgement that programming changes have successfully been applied, and also allows JMRI DecoderPro to interrogate a decoder to make a best guess at the type of decoder that’s installed, what the address is, and so forth.

Programming on main, also known as POM or ops mode programming, doesn’t allow for acknowledgement or reading of CVs, but is handy when simple changes need to be made while a loco is in operation.

We will outline how to use each option below to update a locomotive DCC decoder’s address, as well as identify a loco that is currently on the programming track.

Service mode programming is the preferred method for making wholesale changes to decoder settings as you will receive positive feedback that changes have been made and, if you make a mistake with a DCC address, you can quickly read what has been programmed to correct the issue, or reset them to factory default settings and start again.

To program any other features, refer to the DecoderPro user guide .

JMRI (Programming Decoders)

JMRI is a PC based app that runs on Windows, Apple macOS, and Linux (including Raspberry Pi’s Raspbian (RasPi)).

It relies on the EX‑CommandStation being connected to the PC running JMRI, normally by the USB cable. (It can be done over WiFi, but is not recommended). This means that, even if you setup your EX‑CommandStation for WiFi you will need to connect it to the PC. Don’t worry, this will work without having to load the software on the EX‑CommandStation again.

Installing JMRI

To install JMRI, refer to the installation instructions on the JMRI website.

Once JMRI is installed, launch DecoderPro. If you haven’t previously used DecoderPro or any JMRI applications, you will need to setup your EX‑CommandStation connection. Refer to the JMRi help page for instructions on how to accomplish this.

Using the programming track (service mode)

At this point, DecoderPro will be open at the “Getting Started” screen, assuming you have not used it before, and have no roster entries defined. The loco to be programmed also must be placed on your programming track.

This is the process to create your first roster entry and set the desired DCC decoder address:

Click the New Loco button on the menu bar at the top of the screen
Click the Read type from decoder button at the bottom of the screen
The most appropriate decoder should automatically be detected and selected automatically (multiple matches may be made, so select the most appropriate)
Once only one decoder is selected, the “Create Basic Roster Entry” pane should appear to the right of the decoder list
Enter the desired name in “Roster ID”, enter the desired DCC address in the “Active Address” box, then click the Write button to write the new address to the decoder
An “OK” should appear in the bottom left corner to indicate the write was successful
Click Save to save your roster entry, and then either close the window or repeat the process for other locos

Once your roster entries are populated, if you forget which loco was programmed with what, place your loco on the programming track and click the Identify button on the top menu. DecoderPro will detect the decoder settings and, if they match an existing roster entry, this will be displayed.

To make further programming changes to your decoders, simply select the roster entry, make sure “Programming Track” is selected in the bottom right corner, then click the Program button which will open the full programming dialogue window.

For further information on programming in service mode, see Service Mode Programmer on the JMRI website.

Programming on main (POM or ops mode)

If you wish to set up a new roster entry for a loco that is already on your main track, or you don’t have a programming track available, to a limited extent you can still do this through DecoderPro. You will, however, receive no acknowledgement that the changes have been written successfully.

This is the process to add a roster entry and set the desired DCC address:

Using POM only changes the loco you have selected, not all locos on the track. Which is why you must select a loco first. (Unlike the programming track where it changes everything on it)

Warning

You can theoretically change the DCC address using POM, but only short addresses (below 127) and some decoders don’t even allow that.

Use the Power button at the top of the window to turn track power on
Click the New Loco button on the menu bar at the top of the screen
Unlike the service mode process above, you will need to manually select which decoder is installed in the loco
Once the decoder is selected, the “Create Basic Roster Entry” pane should appear to the right of the decoder list
Enter the desired name in “Roster ID”, enter the current DCC address in the “Active Address” box, then click the Save to save your roster entry, then close the “New Loco” window
To set the desired DCC address, select the correct roster entry (See Warning)
Select “Programming on Main”, then click the Program button
Click the “Basic” tab, set the desired DCC address in the “Active Address” text box, then click the Write changes on sheet button (See Warning)
Close the “Program” window and when prompted, click the Save and close button

For further information on programming on the main track, see Ops Mode Programming on the JMRI website.
