Device Configuration
First, connect the provided USB cable to your
connector/transmitter unit and also to an available USB
port on your computer.
Now that you have connected your USB cable to
your PC and transmitter you will complete the
following steps to configure your device before
placing the unit into operation. You will be using the
configuration software utility (TC Central>>End Device
Configuration Wizard) that you installed onto your PC
in the previous section. If you have not installed the
configuration software utility you should do so now.
During this procedure you will be setting the following
parameters in your transmitter.
Button Operation
1. “ON/OFF”
The “ON/OFF” button on the front of your connector/
transmitter is used to turn your unit “ON” or “OFF”.
2. “SETUP”
The “SETUP” button on the front of your connector/
transmitter is only used during the setup and
configuration of your unit.
Indicator Lights
1. Transmit (TX) Green Indicator Light
The green indicator light marked “TX” on the front of
your connector/transmitter will blink every time the
unit sends data to the receiving unit. Example: If you
selected a 5 second sample rate the green TX LED will
blink one time every 5 seconds.
2. Low Battery (Low Bat) Red Indicator Light
The red indicator light marked “Low Bat” on the front
of the connector/transmitter will turn on when the
battery reaches a level at or below the power level
required for normal operation. When this indicator
turns on it’s time to install a fresh battery in your unit.
For procedures on how to change your battery see the
later section Battery Replacement
Channel Number
This sets a unique address number into your
transmitter. Later, when you set up your measurement
software you will again set channel numbers to receive
readings from the corresponding unit(s). Each unit must
be set for a different channel number for your system to
operate correctly.
Sample Rate:
This will program your device to transmit 1 data
reading to your receiver at a specified time interval.
Available settings are 2, 3, 5, 15, 30, 45, 60, 75 or 90.

Using This Quick Start Manual
Use this Quick Start Manual with your
UWTC-2A-NEMA Temperature-to-Wireless Transmitter
for easy installation and basic operation. For detailed
information, refer to the User’s Guide (Manual # M5044).
General Description
The UWTC-2A-NEMA Temperature-to-Wireless
Transmitters features a stand-alone, compact,
battery powered NEMA rated design that
transmits measurements back to a host receiver up
to 120m (400’) away. When activated the wireless
transmitter will transmit readings continuously
at a pre-set time interval that was programmed
by the user during the initial setup. Each unit
measures and transmits: Measured Temperature,
Ambient Temperature, RF Signal Strength and
Battery Condition to the receiver and is displayed
on your PC screen in real time.
Main Transmitter Board/Input Connections
Software Installation
System Minimum Requirements:
• Pentium Class processor
• Hard Drive Space: 210 MB
• RAM: 256 MB
• 1 Available USB Port
• 1 CD-ROM Drive
• Windows 2000, XP, Vista, 7
Insert the TC-Central User CD that was included with
your receiver unit into the CD-ROM drive of your
PC. Your system should begin the installation process
automatically.
The “Welcome to the TC Central Setup Wizard” screen
should be visible on your computer screen. The installer
will guide you through the steps required to install TC
Central on your computer.
STEP 1. Enter the “SETUP” mode.
To place your transmitter into the “SETUP” mode for
programming follow this procedure:
Press and hold the “ON/OFF” button. While the “ON/
OFF” button is being held, press the “SETUP” button
one time and then release the “ON/OFF” button.
The green (TX) indicator on the front of your device
should be blinking at a steady rate. This indicates that
your device is ready to run the configuration utility
software.
(Refer to Main Transmitter Board/Input Connections
diagram for button locations)
STEP 2. Launch Setup Utility Program.
To launch the End Device Configuration Wizard,
begin by accessing the “Programs” list under your
“Start Menu”.
Scroll through the list to find the Omega “TC-Central”
folder, and then select the End Device Configuration
Wizard.
STEP 3. Programming the device settings.
After starting the setup utility program, the ”Welcome
to the Universal Wireless End Device Configuration
Wizard” screen should be visible on your screen. The
software will guide you through the steps required to
program your device settings.
Device Installation
When installing your device it is important to position
your device in such a way as to optimize the antenna
location within what is known as the “Fresnel Zone”.
The Fresnel Zone can be thought of as a football-
shaped invisible tunnel between two locations that
provides a path for RF signals between your device
and your receiver.
Fresnel Zone
In order to achieve maximum range, the football-
shaped path in which radio waves travel must be free
of all obstructions. Obstacles in the path (especially
metal) will decrease the communication range between
your device and your receiver. Also, if the antennas
are mounted just barely off the ground, over half of the
Fresnel zone ends up being obstructed by the earth
resulting in significant reduction in range. To
avoid this problem, the antennas should be
mounted high enough off of the ground so that the
earth does not interfere with the central diameter
of the Fresnel Zone.
No co-location with other radio transmitters
is allowed. By definition co-location is when
another radio device or the device's antenna
is located within 20 cm of your connector/
transmitter and can transmit simultaneously with
your unit.
Mounting
When mounting your end device, care should be
taken to make sure it is as far away from any metal
objects. If nearby metal gets too close to your unit,
it has the potential to interfere with the way the
unit radiates and may cause signal loss or possibly
even the inability to communicate at all with your
receiver.
