This is a simple Throttle/Controller that can connect to a DCC-EX EX-CommmandStation (EX-CS) directly through the USB port of a computer.
- Chromium-Based Browser version 89 or above (Chrome, Opera, Edge)
You don't need anything to test it out and to run in emulator mode, but to actually run trains you will need:
- An EX-CommandStation (Arduino Mega/Uno or ESP32 Microcontroller + Motor Shield)
- Chromium based browser version 80 or later
NOTE: If you don't have your hardware yet or just want to play with the throttle and see commands being sent to the log window, you can skip to the operation section.
To get started, connect your EX-CommandStation to a computer that has a USB port and have a compatible browser installed. Use a USB serial cable from your computer to the serial connector on the Arduino. Visit our EX-WebThrottle page to start using this program.
Alternatively, you can download the zip file found in the releases section and extract it. Click on the "index.html" file to load the webpage. This method is only recommended if you need a specific version, or will be using it on a computer that does not have internet access. Note: it won't be auto-updated if new versions become available.
To use the program, you can either click on the "serial" dropdown button and select "emulator" to run in emulator mode or after making sure your hardware is properly connected, make sure "serial" is selected and click on the "Connect EX-CS" button.
If the program finds a compatible device, it will popup a window showing you a selection. It may show a line at the top such as "Arduino Mega 2560 (COM3)". Your com port may vary. Click on your board to select it and then click the "connect" button.
You should then be connected to the Command Station (CS) and should see the response from the CS on the web page under the buttons. Make sure your debug console is open. If it isn't, use the slider button in the lower left to open it. You can also open the DevTools window in your browser to see more developer logging.
Now you are ready to run trains! Place your loco on the track and click the power slider button to turn on power to your track. You should see lights on an Arduino Motor Board light and an indication that your loco has power.
Next go to the "locomotive ID" textbox and enter the address of your loco and press the ACQUIRE button. You should now have full control over your loco.
All the function buttons should be working, so you can play with the headlight, horn and bell and any other function assigned to a function button. The commands being sent to the CS and its responses will display in the log window if it is open
In the throttle control area to the left of the function buttons are vertical controls to control direction. The up arrow selects forward, the square button is stop and the down arrow is reverse.
The circular control or vertical slider (chosen by the throttle select slider) can be moved by clicking and holding down the mouse button and dragging, clicking at a spot where you want the throttle to move, or clicking the + and - buttons.
The options button lets you save labels to go on your function buttons for each of your locos. We will be updating this document soon to give you more information on this and other new features.
Note: The emulator doesn't fully replicate the Command station yet. This means that although the software works, not all the responses will be shown in the debug console. We are currently working on this, so it is something that will be fixed.
Once you are connected, you can direct commands o the command station. Thais can be useful if you are having difficulty with the system or a decoder.
For example, enter the <s> command in the "direct command" textbox to get status information from your Command Station, just enter "s" (without the quotes) and press the SEND button. You can send any DCC++ command in this way. You should see <iDCC++...> returned in the log window with your version, type of Arduino, type of motor shield, and some other information.
A complete reference to all the commands is available on our DCC-EX Native Commands Summary Reference page.
If you want to really delve into how this works and help us improve it with your comments or your development skills, please contact us.
To load the Chrome DevTools to look at logging and be able to manually enter "write" commands for testing, click on the Menu (the 3 vertical dots in the upper right hand corner of the Chrome Window), then select "more tools" and then "Developer Tools". Or you can just hit "Ctrl-Shift-I".
