What does WFD-44 Wi-Fi/DCC Trackside
Command Station/Booster do?
The WFD-44 Wi-Fi/DCC Booster is a 5 Amp/3 Amp DCC Booster that
receives a DCC signal from a DCC Command Station and delivers DCC
Track Power to a Power District consisting of a section of track isolated
by a gap in both rails. Here is a summary of its features:
•5 Amp continuous capability
•Fixed DCC Output Voltage determined by power adapter voltage
•3 Amp or 5 Amp Overcurrent Protection
•Input from Track DCC or DCC Control Bus
•Auto-reversing for return loops, wye etc.
•Wi-Fi Monitoring of Status and approximate current load
LED Indicators
Red LED: Lights as soon as power is applied to the module.
Blue LED: Lights when the module receives a valid DCC input and is
supplying DCC to its track outputs. Flashes quickly when an over-current
or short condition is detected.
Amber LED: Lights instead of the blue when the Track Output is
reversed.
Green LED: Flashes when Wi-Fi traffic occurs. Lights continuously when
module is connected to a home network router.
Getting Started
If this is your first purchase of a WFD-44, you have various options to
connect it to your layout:
•Connect the control bus of your existing DCC Command Station to
the WFD-44 as in Figure 2, or
(4) Once your device has connected to the WFD-44 Wi-Fi, open a
browser such as Google Chrome and type the IP Address of the
module:
192.168.7.1
(5) The main menu is displayed as below.
Click on any of the menu items to make changes to the configuration of
the WFD-44 module. The details of the Settings and other pages are
described in the WFD-44 Manual.
As an example, the DCC Status page is shown below:

Using The Wi-Fi Features of WFD-44
The WFD-44 displays a web page containing a menu of features. This
web site is internally generated and does not need a connection to the
internet.
To connect to the WFD-44 web page using Android follow these steps:
(1) Press the Home button and tap the settings icon on your Android
phone or tablet:
(2) Find the Wi-Fi option. On Android 7, you tap Connections on the left,
then Wi-Fi on the right.
(3) You see a list of available Wi-Fi Connections on the right. Look for
one like wftrx_WFD44_1_XXXXXXXX_7, where XXXXXXXX is the serial
number of your unit that appears on its label. Tap on that –no
password is required –and wait for it to connect.
•Use the track DCC (bipolar DCC) output from your existing command
station/booster to your WFD-44 as in Figure 3. You then connect its
track outputs to a new DCC Power District.

Installation Instructions
(1) Connect your WFD-44 according to either Figure 2 or Figure 3. You
can use Wifitrax or any manufacturer’s compatible product to
provide DCC as you wish. The Wifitrax WFD-26, 27 or 28 are ideal.
Just remember to distinguish between Control Bus inputs and
Bipolar Track DCC inputs.
(2) Set the DIP switches on your WFD-44 according to your requirements
as in Table 1.
•Choose a suitable Power Adapter. A 15V DC output is ideal as the
track voltage will then be around 14V.
•Set the Over-Current Shutdown to 3 Amp or 6 Amp.
•Select the DCC Input Source to Control Bus or Bipolar Track DCC
according to whether you are wired as in Figure 2 or Figure 3.
•Select either Auto-Reverse Enable or Disable. If you disable
Auto-Reverse you need to make sure any existing Power Districts are
wired with the same polarity as the WFD-44. Do not enable Auto-
Reverse in two adjacent Power Districts supplied by WFD-44 or they
will both try to reverse and defeat each other.
(3) Connect a suitable Power Adapter to your WFD-44. A 15V DC output
is ideal as the track voltage will then be around 14V. Remember that
the Power Adapter voltage determines the track voltage. The track
voltage is usually about 1V less than the Power Adapter voltage. Do
not exceed the maximum DCC voltage for the decoders on your
layout.
(4) Turn on your command station and WFD-44 Booster. The Red LED
should light immediately followed by either the blue or amber. The
green will only light when you use the Wi-Fi features of your
booster.
