TRANSMITTER ANTENNA

Section 6 – Optional Wireless Transmitter Operation

6.1 Introduction

Compared to a wired connection, a wireless meter provides much simpler
installation. Based on the physical principle of the propagation of radio waves,
certain basic conditions should be observed. The following simple
recommendations are provided to ensure proper installation and correct
operation of your wireless meter.

6.2 RF Communication Basics

Your wireless transmitter sends wireless transmissions to a receiver. The receiver
checks the incoming data for accuracy and processes this data for use by the
measurement software on your PC. Radio signals are electromagnetic waves,
hence the signal becomes weaker the further it travels. While radio waves can
penetrate some solid materials like a wall, they are dampened more than when a
direct line-of-sight between the transmitting and receiving antenna exists.

6.3 Basic System Overview

6

A basic wireless system is comprised of only two main components; a signal
conditioner with a built-in battery powered 2.4GHz radio transmitter, and a USB
powered 2.4GHz radio receiver.

Installation

When installing your meter it is important to position the unit 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 meter and your
receiver.

Figure 6-1. 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 meter and receiver.

6-1

6

Optional Wireless Transmitter Operation

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.

NOTE:

It is important to understand that the environment may
change over time due to new equipment or machinery being
installed, building construction, etc. If new obstacles exist
between your meter and receiver, the devices can be raised
on one end or on both ends to clear the Fresnel Zone of
obstructions.

CAUTION:

Installing your meter in an application were the unit will be
exposed to ambient temperatures above or below the
operating limits specified in this manual will damage your
unit and cause the unit to malfunction and produce incorrect
operation.

NOTE:

Your meter has been shipped to you with a standard
approved antenna. Use of any other antenna than what’s
supplied with your meter will void all FCC, IC and CE
regulatory compliance.

Environment

Omega’s wireless end devices and receiver units have been designed to be fixed
mounted and operated in a clean and dry indoor environment. Care should be
taken to prevent the components of your wireless system from being exposed to
moisture, toxic chemicals and extreme cold or hot temperature that are outside
the specifications listed in this manual.

6-2

The following is a list of basic good practice you should apply when operating
your wireless system.

• Never operate your wireless device or receiver outside the recommended
environmental limits specified in this manual.

• Never operate your wireless end device or receiver in flammable or explosive
environments.

• Never use your wireless end device or receiver in medical, nuclear or other
dangerous applications where an interruption of readings can cause
damage or harm.

• Never operate your end device or receiver with any other battery or power
source than what’s specified in this manual or on the battery compartment
label.

• No co-location with other radio transmitters is allowed. By definition, co­location is when another radio device or it’s antenna is located within 20 cm
of your end device and can transmit simultaneously with your end device.

• Never install end devices within 20 cm or less from each other.

• Never use your end device as a portable device. Your unit has been designed
to be operated in a permanent installation.

• Never install and/or operate your end device closer than 20 cm to nearby
persons.

• Never operate your end device with any other antenna than what is supplied
or listed here in this manual for approved use.

6.4 Transmit Rate vs. Battery Life

Optional Wireless Transmitter Operation

6

Many factors such as ambient temperature conditions and transmitting rate can
have a big effect on the life of the battery used in your DPG409 Digital Pressure
Gauge. Transmitting data places a big demand of the battery in your unit. The
transmit rate is the single most contributing factor in the life of the battery. The
slower the transmit rate you set, the longer the battery in your device will last.
The tables below give some estimates on how long the battery should last vs.
some sample transmit rates you can select when you set up your meter and
operate under normal conditions.

For the DPG409-W wireless digital pressure gauge, the battery life of the device
is controlled by three variables – the battery capacity, the analog output rate, and
the wireless transmission rate. The battery capacity is 9600 mA hours (using 2 of
the 4.8Ah capacity batteries). Below is a table showing the battery life estimates
in both scenarios, at various analog output rates.

6.5 Wireless Transmitter Setup

After connecting the USB cable and running the configuration software as
outlined in Section 3, you will complete the following steps to configure your
wireless transmitter before placing the unit into operation. You will be using the
configuration software utility that you installed onto your PC in Section 3. 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.

RF Channel

This setting determines the operating channel on which RF connections are
made between the transmitter and receiver. The transmitter must be set to the
same channel as the receiver in order for them to communicate.

Network ID

This sets the ID of the Network that the transmitter will be joining. It must
match the setting of the receiver in order for them to communicate.

Receiver Address

Optional Wireless Transmitter Operation

6

This sets a unique address number for your receiver. Later, when you set up
your receiver you will again set the same number to receive readings from the
corresponding transmitter unit(s). Each receiver must be set for a different
number for your system to operate correctly.

NOTE:

If you will be using more than one receiver unit in your area it
is important to set the transmitter address numbers to be a
corresponding number in your TC-Central software. See
Examples below.

For the First Receiver:

Set the address on your transmitters to 101, 102, 103, 104, etc. Then set the
address in your TC-Central software to match.

For the Second Receiver:

Set the channels on your transmitters to 201, 202, 203, 204, etc. Then set the
address in your TC-Central software to match.

This numbering scheme can be expanded to match the number of receivers you
are using.

6-5

6

Optional Wireless Transmitter Operation

Gauge Address

This sets a unique address number into your transmitter. Later, when you set up
