This module is similar to our popular WFD-30 but is designed to conveniently replace the circuit board in your existing Power Cab Panel or Universal Throttle Panel. Simply undo the screws fixing the circuit board in your existing Power Cab Panel or Universal Throttle Panel to the plasic fascia panel, drill out the LED hole to 5mm (#10) and screw in your new WFD-31.
Replace all the cables the same as you had them, follow the instructions and you have Wi-Fi control!

This module provides Wi-Fi control of DCC locomotives and accessories using your NCE Command Station from a hand-held such as a phone, tablet or dedicated throttle that uses the WiThrottle protocol authored by Brett Hoffman. WifiTrax has thoroughly tested operation using the popular and excellent apps Engine Driver for Android and WiThrottle for Apple and guarantees operation for all the scenarios described in our Recommended App Test Report.

If you want a more tactile driving experience, use the popular TCS UWT-100 Universal Wi-Fi Throttle. Again we have carefully evaluated its compatibility.
Please contact WifiTrax support for any questions or issues relating to operation with 3rd-party apps rather than the authors these apps. It is is unlikely that authors of apps will be able to answer questions relating to our products.

Of course you can also operate locomotives using WifiTrax Loco Operator version 3.5 on Windows or Android, in which case you can operate other WifiTrax products such as Switch Machine controllers etc.

The WFD-31 has been developed by WifiTrax with the assistance of NCE representatives in Australia who have tested it with excellent results.

Don't be fooled by the simple appearance of this module. The value is in the firmware!

WifiTrax has developed Complex Real-Time C language code to run in the Silicon Valley Tensilica L106 32-bit micro controller processor licensed by Espressif and built into their Wi-Fi module to do many things:

It provides a WiThrottle Server, just like JMRI except that YOU DON'T NEED A COMPUTER - it's all in this little module.
It provides an NCE CAB Bus interface - the NCE standard to connect Cabs to Command Stations.
It translates all the WiThrottle commands to NCE Cab Bus commands.
It provides an on-board loco roster and turnout list and allows you to maintain it using web pages on your browser.
You can provide meaningful names for the function keys for each loco in your roster and set them to latch or not as required.
You can set WPA2-PSK Security on the device's direct Wi-Fi Access Point with your own password. You can connect more than one WFD-30/31 to an NCE command station so you can take your unit along to your club with your own roster - only those your authorize can access it and drive your locos.
It supports 4 connected throttles out of the box, BUT you can connect it to your home network so that the number of throttles is increased to 8.
Last but certainly not least, you get a complete and detailed on-line manual on all aspects of operation, with clear instructions on using third-party apps with the WFD-31.

To get started with this device, all you need to do is connect it to the CAB Bus socket on your NCE command station, connect your smart phone, tablet or Universal Wi-Fi Throttle to the device's Wi-Fi Access Point and start one of the recommended Apps such as WiThrottle, Engine Driver or Loco Operator.

Select the broadcast WiThrottle server, and drive trains by selecting a locomotive using its DCC address. But there's a great deal more:

You can create a locomotive roster similar to JMRI, specify a name and DCC address for each entry, and customize the function keys for the decoder in each loco. When you select from the roster, displayed by your smart-phone app, all the function keys will be labelled for that loco and decoder. Maybe you have diesel locos, where F2 should show "Horn" and steam locos where F2 should show "Whistle". Similarly, some locos might have various lights that others do not.

You can define a list of DCC accessory turnouts that will be loaded into WiThrottle or Engine Driver when you connect.

With direct connection to the WFD-31 module, you can have up to 4 hand-held throttles, BUT you can connect the module to your home network which allows up to 8 throttles connected at any one time. So when there are many operators, you can have up to eight throttles without needing to install multiple WFD-30/31 modules and remember which one you should connect to. Also all your hand-helds are connected to your home net, so you can access the internet and use other apps at the same time as driving your trains and you don't have to connect to the unit's Wi-Fi each time.
