What does WFD-30 NCE Cab Bus Wi-Fi
Interface do?
The WFD-30 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. It connects to one of the CAB
Bus sockets on your NCE Command Station or to the right-hand “Extra Cab” socket on the Power Cab
Panel, and allows Wi-Fi control of your DCC locos via the WiThrottle Server that it provides.
•You can drive trains using a smart phone or tablet as a hand-held throttle provided it has Wi-
Fi capability and you have installed one of our recommended apps in Table 2
•You can use a special-purpose hand-held throttle designed to control trains using the
Hoffman WiThrottle protocol, such as TCS UWT-100.
•You can use a Windows or Apple computer, such as a laptop or desktop, with a
recommended installed app from Table 2.
•Four throttles at a time can join the WFD-30 Wi-Fi Access Point, but you can avoid this limit
using “Home Net” mode as described later in this manual.
You don’t need to install JMRI to use the WFD-30
If you have been using an app on your phone to drive trains, via a computer running JMRI, you can
now bypass JMRI and connect your phone directly to the WFD-30. You can still use JMRI if you want
to –it just means that the WFD-30 and the JMRI installation will both appear as WiThrottle servers in
your app. Similarly, if you use more than one WFD-30, they will each appear as WiThrottle servers
available to your app.

Figure 1 Connections and switches on the WFD-30.
Figure 1 shows the WFD-30 module with its connectors labelled. There are two NCE CAB Bus connections on
the left of the module. Either of these can be connected to one of the CAB Bus connections on your NCE
Command Station. You should always use NON-REVERSED cables with RJ-12 6P4C Modular Plugs on each end –

WFD-30 NCE Cab Bus Wi-Fi Interface Operating Manual
P a g e | 10 WifiTrax Model Science
www.wifitrax.com
the coiled cable from NCE is, of course ideal. Warning: Some phone cables are reversed. The WDM-30 will not
work with these but it will not be damaged. See the section “More about Cables” if making your own. The
unused Cab Bus socket on the WDM-30 can be used to connect any other NCE Cab such as a Pro cab. If you are
using a Power Cab, do not connect the flat cable to the spare connector on the WFD-30. Only connect the
flat cable to the Power Cab Panel (PCP) as instructed by NCE.
The switches in the middle of the module are used to set the address that the module will respond to on the
NCE Cab bus, the factory default being address 10. Please refer to Table 1 if you need to change the Cab Bus
address to avoid conflict with other NCE Cabs that you might be using on your layout, or if you are using NCE
equipment that has a limited range of Cab Bus addresses.
What is WiThrottle protocol?
WiThrottle protocol is a set of commands and data formats, authored by B. Hoffman and used by JMRI, that
allows devices such as iPhone, Android phones and tablets to control trains and turnouts through a WiThrottle
server. It has become something of a standard and is used by other products. You can find technical
information here:
https://www.jmri.org/help/en/package/jmri/jmrit/withrottle/Protocol.shtml
What is JMRI?
JMRI (Java Model Railroad Interface) is a system of computer programs and support software that can be
installed on a computer to do many things with your model railroad including running trains, controlling
turnouts and programming DCC decoders. JMRI provides a wiThrottle server to allow you to run trains from
phones etc. You can learn about JMRI here:
https://www.jmri.org/

Figure 3 Connecting the WFD-30 Module to a Power Cab Panel
(1) CAB Bus Address: All Cabs connected on the NCE Cab Bus must have a unique address. Use
Table 1 to set the Address Switches to select an unused CAB address. The factory default is
CAB Address 10. NCE Power Cab earlier than version 1.65 and some early NCE command
stations do not scan beyond 4, so in that case, you must use address 3 or 4.
The last entry in Table 1 causes factory reset. If you wish to completely reset the unit, power down, set the
switches to this position, power up and wait 10 seconds, power down and return them to select the Cab address
you want. Do not leave the switches in the factory reset position.
Important note for Power Cab users: If you are using a Power Cab in “Master” mode so that
it acts as the DCC command station, it will work best with version 1.65B. WFD-30 will work
with versions of Power Cab with version 1.28 and later. Version 1.28 only supports Cab
Addresses 3 and 4, so you must set your WFD-30 to one of these using the DIP switches as in
Table 1. With version 1.65B, you can leave it in the default Cab Address 10 but if something
else uses Cab Address 10 you will need to change it.
If you are using Power Cab in Pro-Cab mode, as a cab on another NCE system, this does not
apply, but you must make sure the WFD-30 is given a different address to the Power Cab.
(2) Mounting: Mount your WFD-30 Module in a convenient location where nothing metal will
touch it, either in a plastic box or at a convenient location on your baseboard or fascia.
Please see the “Mounting Suggestions” section. As a minimum, make sure it will not be
dragged around by pulling on a connected cable and touch on some metal object. Do not let
the unit touch powered track or it may be damaged beyond repair!
(3) Connect: Use an NCE Cab Bus cable to connect to your NCE Command Station as in Figure 2.
Make sure your NCE Command Station is connected to power and track or booster according
to its instructions. Turn on power to your NCE Command Station. The WFD-30 module gets
its power from the command station via the CAB Bus.
If you are using an NCE Power Cab in “Master” mode, you must connect the flat cable
supplied with the Power Cab to the left-hand socket of the Power Cab Panel (PCP) use the
coiled cable to connect your WFD-30 to the right-hand socket of the Power Cab Panel.

LEDs on the WFD-30
The WFD-30 has three LEDs.
Red LED. This will light as soon as power is applied to the module through the NCE Cab Bus
connection. It will stay alight continuously. Any flashing indicates a power fault.
Blue LED. This will light as soon as the NCE command station begins polling the module on its Cab
Bus. The blue LED will also flash briefly off when the module responds to a poll on the Cab Bus. If the
blue LED does not come on at all it may indicate that the command station is not working properly
or is not polling the address to which the WFD-30 is set.
Green LED. This has two modes. In direct mode, the green LED will normally be unlit but will flash
when the module receives Wi-Fi Network traffic, for example, when it receives a command from
your hand-held device. In Home-net mode, the green LED will light continuously when it has
successfully connected to your home network Wi-Fi router. It will also flash briefly off, when the
module receives Wi-Fi traffic such as a command from your hand-held device. Hand-held devices
need to provide a “heartbeat” to the WFD-30 WiThrottle server, so the green LED will flash regularly
even when no commands are being sent.
Driving your First Trains
You can drive trains using any of the throttles described in Table 2.
Some throttles use an installed app on a smart phone or tablet. WiThrottle and Engine Driver are
examples that use the WiThrottle protocol and provide driving of trains, and control of accessories
and routes.
Wifitrax Web Throttle is an app that runs as a web page in a browser such as Safari, Chrome or Edge.
It is automatically installed from the WFD-30 itself.
TCS UWT-100 is a dedicated Wi-Fi throttles.
The WFD-30 does not support Layout Power or JMRI panels. You can configure the WFD-30 using its
Web Pages which are accessible using WiThrottle (Full Version) or Engine Driver or indeed any web
browser via the device’s default URL http://192.168.7.1

Table 2 Recommended Apps that work with the WFD-30
Getting Started with Wifitrax Web Throttle
Wifitrax Web Throttle is a Throttle app that is contained within the WFD-30 and runs in most
browsers on most devices using a language called HTML and JavaScript. To use the app on your
device, you must first connect your phone or computer to the Wi-Fi network provided by the WFD-
30.
Make sure power to your NCE Command Station and booster is on, the WFD-30 is connected and
there is a locomotive on the track with a DCC address that you know.
Connect your Phone, Tablet or Computer to the WFD-30 Wi-Fi Network. The WFD-30 provides its
own Wi-Fi network with the name (SSID) of wftrx_WFD30_1_XXXXXXXX_7 where XXXXXXXX is your
module’s serial number. You must connect to this network to use WFD-30. Connecting to the
network is a bit different for Apple, Android and Windows.
Connecting from Apple IOS
(1) Tap the Settings icon on your iPhone or iPad, etc.
(2) Tap Wi-Fi on the left-hand menu. Under CHOOSE A NETWORK on the right, the list should
include one like wftrx_WFD30_1_XXXXXXXX_7, where XXXXXXXX is the serial number of your
unit that appears on its label. Tap that Wi-Fi Network. You must always connect to this Network
otherwise your device will not see the WFD-30.
(3) No password is required and after a few moments you should see that it has connected.
