5.1 Setup and Configuration
5.1.1 Connecting your device
Connect the USB cable to your connector/transmitter unit and also to an
available USB port on your computer. See figure below. This cable was provided
in the box with your receiver unit. This same cable is used for programming
your nd Device and for receiver operation later.
Figure 5-1. USB Cable
5.1.2 Configure Your End Device
Now that you have connected your USB cable to your PC and transmitter you
will complete the following steps to configure your nd Device before placing
the unit into operation. You will be using the configuration software utility that
you installed onto your PC in Section 4. If you have not installed the

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). ach unit must be set for a different
channel number for your system to operate correctly.
If you w ll be us ng more than one rece ver un t n your area t
s mportant to set the transm tter address numbers to be a
correspond ng number n your TC-Central software.
Example Rate
For the f rst rece ver: Set the channels on your transm tters to
101, 102, 103, 104, etc. Then set the channels n your TC-
Central user software to match.
For the second rece ver: Set the channels on your transm tters
to 201, 202, 203, 204, etc.
Then set the channels n your TC-Central user software to
match.
Th s number ng scheme can be expanded to match the
number of rece vers you are us ng.
Sample Rate
This will program your nd 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
seconds
The sample rate you set w ll have the most d rect effect on the
l fe of the battery n your End Dev ce. It s recommended that
you set the longest sample t me that your appl cat on can l ve
w th to extend t me between battery replacement. See

5.2 Mounting, Installation and Antenna connection
5.2.1 Mounting
Figure 5-10. 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
lose or possibly even the inability to communicate at all with your receiver.
5.2.2 Installation
When installing your nd Device it is important to position your device in such
a way as to optimize the antenna location within what’s 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 nd Device and
your receiver.

END DEVICE
FRESNEL ZONE
RECEIVER
ANTENNA

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 nd Device and
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.
It s mportant to understand that the env ronment may
change over t me due to new equ pment or mach nery be ng
nstalled, bu ld ng construct on, etc. If new obstacles ex st
between your End Dev ce and rece ver, the dev ces can be
ra sed on one end or on both ends to hopefully clear the
Fresnel Zone of obstruct ons.
No co-locat on w th other rad o transm tters s allowed. By
def n t on, co-locat on s when another rad o dev ce or the
dev ce’s antenna s located w th n 20 cm of your
connector/transm tter and can transm t s multaneously w th
your un t.
Never nstall mult ple End Dev ces w th n 20 cm or less from
each other.
Never use your End Dev ce as a portable dev ce. Your un t
has been des gned to be operated n a permanent nstallat on
only.
5.2.3 Antenna Connection
Your nd Device has been shipped to you with a standard approved antenna.
Use of any other antenna then what’s suppl ed w th your End
Dev ce w ll vo d all FCC, IC and CE regulatory compl ance.
