Getting Started
The UWT-100 is powered using two “AA” batteries. Many battery chem-
istries can be used, including Alkaline, NiCd, NiMH, Lithium, etc. The
two AA batteries must be installed into the battery holder in the correct
orientation in order to power up the throttle. The required polarity of the
batteries is indicated within the battery holder.
Once two “AA” batteries have been installed, press any button and hold
for 3 seconds to “wake up” the UWT-100. Once the unit is awake, press
button 2 to complete the startup process.
Connecting to WiFi
On startup, the UWT-100 will begin searching for known WiFi networks to
reconnect to. It is safe to assume your network(s) will not be identical to
ours. Since this is the case, the throttle will acknowledge the lost connec-
tion and will display a screen that will look like Fig A. In order to connect
to a new WiFi, select option 2 “Add New WiFi” which will call up a list of
methods for adding a new WiFi connection. Fig B.
It is recommended from this point that you use Option 1 “Scan for WiFi”
to nd your WiFi network - this may be a WiFi router connected to your
JMRI, a LNWI, or other device. A list of available WiFi options will be
displayed. Select your desired WiFi. Digitrax LNWI devices will start with
a prex “Dtx1-LnServer_(...)”.
Pro Tip: Digitrax LNWI devices do not require a password to be entered to
connect. If your WiFi router is password-protected, you will be prompted to
enter your WiFi password.
Pro Tip: Pressing button 7 at this time will startup the throttle in bootloader
mode. Pressing any other button besides button 2 or 7 will cancel the
startup and power the unit down.

Connection Issues
There are two network connections the throttle must make in order to
communicate to your command station: WiFi and Server.
WiFi - The WiFi connection is your router or WiFi device.
Server - The server is the host which communicates and translates be-
tween your command station and throttle.
Please refer to the steps below to troubleshoot your connection.
Troubleshooting the WiFi connection
This section will help you troubleshoot your network connection after a
“No WiFi found” error. If no WiFi is found, there are a few likely causes:
1. Your router or WiFi network is not turned on or otherwise inoperational.
2. You have not yet connected to a WiFi.
3. Your WiFi password was entered incorrectly.
Solutions for WiFi issues:
1. Turn WiFi device or router on, and check power supply for issues.
2. Follow the steps in First-time Setup Process to connect to a WiFi.
3. Double-check and re-enter your password.
Troubleshooting the Server connection
This section will help you troubleshoot your server connection in the
event the “Server Not Found” menu is displayed. One of the following
likely has happened:
1. The JMRI WiThrottle Server is not on/running.
2. Your command station is not turned on/plugged in.
3. The wrong connection mode is selected. JMRI, LNWI, and all other
potential connections communicate via the “WiThrottle” protocol. If
your connection mode is set to “LCC” for the connection to your layout,
change this to the WiThrottle protocol.
4. mDNS failed to nd the WiThrottle Server.
Pro Tip: Digitrax LNWI and MRC WiFi modules function as both the WiFi
and the Server simultaneously.

Solutions for server issues:
1. Reboot the computer running JMRI, turn JMRI and command station
on, and restart the WiThrottle server. Once complete, select menu option
“Try Again.”
2. Use the menu options labeled “Auto-detect LCC/WT” or “Change LCC/
WT Mode” and select “WiThrottle Protocol” - an asterisk (*) will appear
next to the current mode.
3. mDNS is a WiFi protocol which is used to automatically load the IP
address and Port number of a server connection. This protocol is not
bulletproof and can fail. If you use phone apps, you may be familiar with
manually entering the IP and Port Number of your JMRI WiThrottle Serv-
er. The UWT-100 is also capable of doing this. Select “Set IP Address”
from the Server Not Found menu (option 2) and set the IP address and
port number as indicated on your WiThrottle server window in JMRI.
Troubleshooting an LNWI connection
If you are unable to establish a connection with your LNWI device, follow
the steps below:
1. As simple as it sounds, turning the LNWI device off and on again will
often solve connection issues.
2. Ensure that the number of connections to a specic LNWI device
is not greater than four. LNWI devices have a limit of four connected
devices at one time - including phones running apps like WiThrottle and
EngineDriver. Turn off or disconnect one of the devices connected to the
LNWI and see if the problem disappears.
3. Check that your saved LNWI device is turned on. In situations where
there are multiple LNWI devices in use, the throttle may attempt to con-
nect to one that is not powered on and available.

Using the UWT-100
Power On/Off
To turn on the UWT-100, press and hold any button on the keypad for 3
seconds, followed by button 2 to power up the throttle. If you would like
to access the bootloader mode for rmware updating, press button 7
instead of 2.
If left idle, the throttle will automatically shutdown on its own after a
user-congurable timeout. The default is 15 minutes. You may choose to
shut down the throttle at any time via the main menu. To do so, enter the
Menu and select option 9 “Power Off”.
Menu Navigation
The Menu button will open the UWT-100 main menu. There are
functions and options in the menu that can customize your user experi-
ence and are helpful for throttle operations. Within the menu structure
of the UWT-100, a color-inversion cursor is used to indicate the position
of the selection within each specic menu. A selected menu item will be
indicated by a black bar surrounding white text.
Navigating the main menu can be performed a variety of ways. Rotating
the scroll wheel will navigate up or down through menu items one at a
time. Use of the Single Chevron keys will also shift the cursor one
item at a time, and use of the Double Chevron keys will move the
page up or down one full screen width at a time.
Each menu option corresponds to a keypad button from 0 - 9. Pressing
the corresponding button will immediately select that numbered menu
option. If you choose to manually browse for a menu option using the
cursor, that option may then be selected by pressing the Enter key.
If you would like to know what a menu option does, rst consult the Help
Text.
The “Help” Button
The Universal WiFi Throttle contains information that explains most
menu options and operations. To access these tips, you may press the
button at any time to access the help text for the currently highlighted
menu option. Help text is also available in menus by using the button
and will be labeled “Help” on-screen.
?

A scroll bar will appear on the right side of the screen if more text is avail-
able. Scroll up or down to see additional text by using the thumbwheel or
the chevron keys. The Single Chevron keys will navigate one line at
a time, and the Double Chevron keys will navigate one page.
The “Help” Button on the Drive Window
Pressing the button on the drive window will bring up the “Function
Help” screen. This screen displays all available function buttons, what
they do, and their status (on/off). Pressing the Shift key will cycle
through the pages of functions from 0-28. Functions highlighted in a
black box with white text are “on.” This feature will only display named
functions for each function number if the throttle is connected to a JMRI
WiThrottle server and has a roster entry whose functions have been de-
ned in the “Labels and Media” section. A LNWI device or other system
that is unaware of function assignments will not use text labels, but will
still indicate whether the function is on or off.
Programmable Buttons
There are eight buttons on the UWT-100 that can be assigned functions
by the user. These buttons can be reprogrammed to activate a function
different than their default assignment. The top four buttons (directly
below the screen) have on-screen descriptions that indicate their assign-
ment. If not assigned a function, they will revert to their defaults or be
blank.
You can access button conguration options via the Settings menu. The
remappable buttons will adjust based on your congured choices, the
command station, and the selected locomotive’s roster entry. If you are
using a command station which does not communication function data
such as a LNWI, the buttons may return to their defaults or not display
names.
When connected to JMRI, the throttle will display function names and op-
erate the functions of your locomotive based on your roster entry regard-
less of decoder manufacturer or the numerical function assignments of
that locomotive. The buttons will intelligently display and operate based
on the function names as established in your JMRI roster entry under
[Your locomotive]>Labels and Media>Function Labels.
?

Operations (Drive Window)
The Drive Window provides an overview
of your currently selected locomotive
and other important status indicators.
When no locomotive is selected, an “E”
will be displayed in the top left which
stands for “Empty”. If you had previously acquired a locomotive address
prior to powering down, the throttle will attempt to re-acquire it. In order
to operate a locomotive, use the Select Locomotive button . Button
1 defaults to the quick recall function which will swap between the
two most recently used addresses/names.
Select A Locomotive
Press the button on the keypad to access the locomotive selection
screen. Users are given two options for selecting a locomotive.
1. Enter the cab number manually using the numerical keypad.
2. If the throttle is connected to JMRI, all locomotive IDs (names or
numbers) will be automatically loaded from the JMRI roster list. If you
have a long roster, you can start typing the address to lter your available
options. Use the scroll wheel or chevrons to navigate to the desired loco-
motive, then press the Enter key to select it and return to the drive
window. To assume control of a different locomotive, press the locomo-
tive button on the keypad again.
Using Loco Functions
Pressing the numerical buttons on the keypad will operate the function
assigned to that number on your locomotive. When a function is turned
on, the function number will be displayed on the screen.
To select higher function numbers than 9, press the Shift key .The
new function page selected will “persist,” meaning that you must press
the shift key again in order to continue through function pages. This was
designed to allow for easy repeated operation of higher-number func-
tions. On the left side of the screen, a small 1 or 2 will indicate that you
are controlling higher functions: 1 for functions 10 -19, or 2 for functions
20 - 28. Function 29 is not a valid function on most DCC systems.
Pro Tip: If you would like to relinquish control of your currently selected
address, enter the Menu and select “Release” followed by either the
“Release” or “Dispatch” options. Once a locomotive address has been
released, it will become the rst option available in the recall list.

Reverse Direction
The direction of the locomotive is indicated by the arrow displayed under
the cab number. The upward facing arrow indicates the unit will travel
in it’s forward direction, and the downward facing arrow indicates it will
travel in reverse. Users may change the direction of the unit by using the
Reverse Direction key directly below the thumb wheel.
Change Speed Step
To adjust the speed of the active locomotive, roll the thumb wheel in
the direction of the screen to increase speed, and away decrease the
speed. The keys will increment or decrement the speed by 1 step.
The keys will increase or decrease the speed in larger steps. This
is a congurable option in the “Drive Settings” menu. These buttons are
programmable and can be assigned other functions by the user via the
“Mappable Buttons” menu. Refer to the Programmable Buttons section in
this guide for more information.
Emergency Stop
The UWT-100 has a unique 3-Stage Emergency Stop function.
Some stages will not be supported on certain DCC systems. Stage 1 is
supported under all DCC systems that communicate via the WiThrottle
Protocol.
1. To bring the active locomotive to an immediate stop, press the red
Emergency Stop (E-STOP) button once. A message will appear: “E-
STOP THIS LOCO.” This message will persist until the speed is adjusted
OR the E-stop button is pressed again. A countdown will appear beside
the E-STOP message.
2. If the E-STOP button is pressed a second time before the countdown
nishes, the E-STOP button will stop ALL of the locomotives on the lay-
out/track. The countdown timer will reset also.
3. If the E-STOP button is pressed for a third or more times before the
countdown nishes, the E-STOP button will power off the layout. The
screen will read “E-STOP LAYOUT OFF” and “POWER OFF.” Locomo-
tives will not respond to commands until the E-STOP LAYOUT OFF is
lifted. Press the E-STOP button again while in shutoff mode to restore
operation.
To release any of these stages of E-STOP, wait until the countdown has
nished and press the E-STOP button again.

Resets and Troubleshooting
In the event that your UWT-100 encounters software issues or becomes
unresponsive, please follow the instructions below to reset the throttle.
Option 1: Remove Batteries
99% of crashes can be xed by simply removing the batteries. This will
power down the throttle. Simply replace the batteries and power up nor-
mally.
Option 2: Factory Reset
In the event that things have gone completely sideways and removing
the batteries from the UWT-100 does not solve the problem, a factory
reset may be performed. To perform a Factory Reset, Navigate to Menu
> 8 Throttle Settings > 2 Factory Reset.
Performing a factory reset will erase all network proles, user settings,
and throttle settings. After performing a factory reset, you will need to
re-enter your WiFi connection information as outlined in the section First-
time Setup Process.
Pro Tip: Often, a crash will cause your unit’s LED ashlight to blink in a
short sequence. Power down and reset your throtle to restore operation.
