What does WFD-31 NEC Cab Bus Wi-Fi Interface do?
The WFD-31 allows you to drive your DCC trains from a hand-held
untethered controller by providing a Wi-Fi connection to NCE command
stations and boosters. In PCP mode, it replaces the circuit board in an
NCE Power Cab Panel (PCP) or in UTP mode a Universal Throttle Panel
(UTP) and provides Wi-Fi control of your DCC locos as well as the original
functions of the PCB or UTP.
•You can drive trains and control DCC accessories using a smart
phone or tablet as a hand-held controller provided it has Wi-Fi
capability and you have installed one of our recommended apps in
Table 2 such as Engine Driver on Android and WiThrottle on Apple.
•You can use a hand-held throttle designed to control trains using the
WiThrottle protocol such as the TCS UWT-100 Universal Wi-Fi
Throttle.
•You can use a Windows or Apple computer, such as a laptop or
desktop, with a recommended app from Table 2 installed.
•You can connect four throttles at a time but you can increase this
limit using a “Home Net” to six as described in the manual.
•You may have used a computer running JMRI, you can now bypass
JMRI and connect your phone directly to the WFD-31.
•You don’t need to install JMRI to use the WFD-31

(10)When you want to drive a different loco, tap the button at the
top, 115(L) in this example, then on the Select/Release screen,
tap Release before selecting a new loco using a different DCC
Address. You can use the “Recent” checkbox option to avoid
typing the DCC address over and over.
More Tips
Making Wi-Fi Connection Easier: Go back to your Android Setting and
tap the wftrx_WFD31_1_XXXXXXXX_7 Wi-Fi network. Make sure the
Auto Connect option is turned on. On your other Wi-Fi connections
make sure the Auto Connect option is turned off. That way your Android
device will always connect to the module if its powered on.
Auto Connecting in Engine Driver: Tap the “three dots” in the top right
and select Preferences from the menu. Find “Connect Preferences” and
“Auto Connect to First Throttle Server”. Tap the check box to turn it on.
That way Engine Driver will connect to your WFD-31’s WiThrottle Server
whenever it is available.
Avoiding Hang-ups: It’s best to release your loco before powering down
your WFD-31 and NCE system. When you power up again, Engine Driver
should reconnect, but if not, you may have to restart Engine Driver.
Please consult the Engine Driver “About” menu for more information about the
app. It is possible to control more than one locomotive at a time and select
different display appearances and preferences. Consult the website for more
