5Installation Checklist
NoWire installation requires the following items:
5.1 Required items included
•NoWire 1100 with internal receiver.
•Power supply: 12VDC, 500mA Class II.
•mall flat head screw driver for NoWire terminal blocks and transmitter terminal block
connections.
5.2 Items sold separately
•EN1501 pulse transmitters or EN1210 universal transmitters for wireless points.
•Outdoor enclosures to house the transmitters.
•Meters with digital pulsers.
5.3 Hardware you must provide
•Low voltage wiring (telephone, cat5 or thermostat wire) for connection from your meters to the
transmitters, from the meters to the wired pulse inputs of NoWire, and from the pulse outputs
to your input equipment.
•R 485/R 232 compatible cabling for connection to Com2 Modbus serial port or terminal block
connection.
•Mounting screws for attaching NoWire enclosure to a flat surface.
•½” conduit and conduit fittings connecting into NoWire.
•Any additional tools required for the installation.
6Installation Instructions
6.1 Mount the NoWire enclosure
•Here are some items to consider when deciding where to permanently locate the NoWire
enclosure.
oPlace where it will be easy to view the NoWire LCD display.
oNoWire is outdoor rated if proper watertight conduit connections are used.
oLocate out of direct sunlight to avoid exceeding the maximum temperature rating.

NoWire Model 2100 Installation and Operation Manual
NoWire Model 2100 Submeter Solutions, Inc., 888-64METER Page 10
oLocate near a 120V outlet where the NoWire power supply will be plugged in.
oAllow room for conduit bends and runs that connect to the bottom of the NoWire
enclosure. (if required for application)
oLocate away from other equipment per your local electrical codes.
oLocate in an area that allows for optimal wireless communications from the meter
transmitters. Though the wireless communications was designed for use inside of
buildings with obstacles and such it is best to avoid mounting NoWire in enclosed rooms
that have metal or thick rebar reinforced concrete walls or deep down in sub-basements
far away from the transmitters that need to be seen by it. If this is unavoidable then
you may need an external receiver (NoWire 1100-2) that can be mounted in an optimal
location connected to NoWire up to 50 feet away. Repeaters may also be used in this
situation. ee the Wireless Theory of Operation section.
•Remove the NoWire cover by unscrewing the 4 corner screws on the cover.
•Note the deep channels in the corners of the enclosure that have a 1/8” hole at the bottom.
This is where mounting screws are inserted. These do not need to be water tight since they are
outside the front cover gasket.
•Using the appropriate mounting screws for your location, attach the NoWire enclosure to your
flat surface.
•If you wish to use conduit for routing your NoWire wiring, you may remove the wire fitting on
the bottom of the NoWire enclosure and attach a ½” conduit. Use a water tight fitting if you
need to keep NoWire water tight.
6.2 Attach optional external wiring to NoWire
6.2.1 Wired Pulse Inputs
If you are using wired pulse inputs to directly connect your meters then wire the pulse output wires
from the meters into terminals P1 through P4 utilizing the PG terminals as the common ground
reference point. ee [link] for more details on wired pulse inputs.
6.2.2 Wired Pulse Outputs
If you are using the pulse outputs to connect to external equipment do the following: For pulse output
#1 wire the 1+ terminal to the positive signal of your equipment and the 1- terminal to the negative or
ground reference signal of your equipment. For pulse output 2 through 4 wire to terminals 2+/ 2-, 3+/
3-, and 4+/ 4- respectively.
6.2.3 R 232/R 485 Connections
If you are communicating with NoWire using Modbus connect using R 232 or half duplex multi-drop
R 485. For R 232 connections connect your R 232 cable to NoWire COM2 DB9 female connector. For
R 485 either connect to D+, D-, and GND on the NoWire terminal block or connect to pin 1 (D+), pin 9
(D-) and pin 5 (GND) to NoWire COM2 DB9 female connector.
6.2.4 Apply Power to NoWire
NoWire comes with a 12VDC power supply. Before plugging the power supply into a 120V outlet, route
the power supply wire up thru the NoWire wire entry location on the bottom of the enclosure and
connect the wires to the V+ and V- terminal block on the bottom left side of the NoWire circuit board.
Be sure the positive wire is connected to V+ and the negative wire is connected to V-. The + and –
designations should be shown on the power supply itself or the power supply wires. Once your power

[Meter Reading] The meter reading value of the input point. The Pulse Value as defined in the setup
menu for this point is added to the Meter Reading for each new pulse received.
[Units] 7 characters as defined in the setup menu for the input point.
You may also see the wireless input point status by viewing the “Xmitter tat” setup screen for any
individual wireless input point in the setup menu.
8.1.2 System Status Screen
At the beginning of each input point display screen rotation the ystem tatus creen is displayed.
The second line shows the individual wireless input point status conditions. If more exist than can be
displayed a “+” is displayed at the end of the line. The above example indicates wireless input point #11
has been reset and wireless input point #9 and #11 have a tamper condition. “ ystem OK” message
indicates no wireless input issues exist.
8.1.3 Status LED codes
The tatus LED located just above the input power terminal block signifies the conditions and status of
the system and all inputs. When a condition exists it “blinks” a code indicating the priority of the status,
one blink, highest priority, 3 blinks, lowest priority. Count the blinks by the number of times the tatus
LED blinks red before pausing.
Solid reen: No input point issues exist.
One Red Blink: One or more wireless inputs haven’t been seen for more than 24 hours. Other conditions
may exist of lower priority. This high priority condition also causes the backlight on the LCD screen to
blink periodically to alert attention.
Two Red Blinks: One or more wireless input has a low battery condition. Other conditions may exist of
lower priority.
Three Red Blinks: One or more wireless input has a tamper or reset condition.
If any of the wireless inputs have the conditions above and are assigned to a pulse output the red LED of
the pulse output will blink the individual input point condition.

8.2 Wireless System
8.2.1 Wireless hardware
NoWire utilizes the Inovonics Echostream wireless equipment for its wireless communication backbone.
ince 1986, Inovonics Wireless has shipped almost two million Radio Frequency (RF) products. Inovonics
has been a pioneer and a leader in the field of wireless signal/control and voice communications.
Inovonics developed the TapWatch® submetering system based upon their field proven wireless security
systems and has been the leading wireless submetering system since it was introduced in early 1998.
8.2.2 How the wireless communication works
The system works in the unlicensed wireless spectrum of 902-928 MHz which is the same as many
cordless telephones, security systems, wireless modems, etc. pecifically it uses a frequency hopping
spread spectrum strategy. An Inovonics Wireless battery operated transmitter is installed on each
meter that provides a dry or electronic contact pulse output. The transmitter sends a data packet about
once an hour broadcasting its unique transmitter number, the current count of pulses gathered from the
meter, and any other special information. The other information is data like a low battery or to inform
that someone has opened the cover of the transmitter (called a tamper). The transmitter is low powered
so the battery will last a long time (up to 8 years).
ince the transmitters have limited range and there can be environmental barriers to radio frequency
transmission, NoWire with its receiver may not be able to hear the transmission of data. To allow for
this, Inovonics wireless repeaters are installed at key locations on the site. The repeaters are higher
powered than transmitters and are connected to AC power. They take valid transmissions and repeat
them at high power so the NoWire receiver can hear the message. Multiple repeaters may be used to
relay the message to the NoWire receiver. NoWire collects the messages, deletes any duplicate ones,
stores, and processes them to display meter readings.
8.2.3 Basics of Radio Frequency (RF)
It is necessary for installers to understand the basics of radio frequency and the types of environmental
factors that can result in the NoWire system not working or performing at peak efficiency.
8.2.3.1 Radio Frequency in eneral
Radio Frequency is electrical energy that is conducted through the air. It requires a transmitter to send
the information, and a receiver with antennas that receive the information. Antennas either radiate
(emit) a signal, or receive a signal, or they can do both. The electricity that is sent through the air has a
frequency. It looks like a wave. As the wave goes further and further from its sending antenna, the signal
propagates and becomes weaker.
8.2.3.2 Frequency Spectrum
NoWire wireless communications use the unlicensed frequency, 902- 928 MHz, the same frequencies as
are used by some cordless telephones, security systems, and other miscellaneous devices. The

NoWire Model 2100 Installation and Operation Manual

frequencies that are used for RF transmission are regulated by the government. In the United tates, the
FCC (Federal Communications Commission) decides who is able to use which frequencies and for which
purposes, and it issues licenses for specific frequencies for specific functions (like radio stations, TV
stations, cell phones, etc.) In the U. ., there are a few frequencies called the unlicensed spectrum which
anyone is allowed to use within certain limits. No end user license is required to use products using
these frequencies. Devices using these frequencies are restricted in power so they don’t interfere with
other devices using this same part of the spectrum. (For example, these are the frequencies many of us
use for cordless telephones in our homes.)
8.2.3.3 RF Factors That Will Affect NoWire communications
The amount of transmission power is a factor in how far away the signal can be heard. As RF leaves a
transmitting antenna, signal strength decreases as the distance from the transmitter increases.
Radio signals can be affected by atmospheric conditions resulting in phenomena called fades and
multipath. Both fade and multipath can result in a particular frequency not transmitting efficiently at a
given place at a given time. In other works, it could be present one minute and gone the next for one
frequency at one place. Radio signals can bounce or be reflected off objects, or be absorbed by some
objects. ome materials affect RF more than others. Many, but not all, of the materials used in building
construction and landscaping will affect how RF works.
As stated, some materials allow RF to pass through, some materials block or disperse the radio waves,
and yet other materials absorb the radio waves. For example:
•Wood, sheet rock, plain glass, usually let the RF pass.
•Metal, metal studs, stucco with wire mesh, chain link fencing, plaster with wire mesh, concrete
with wire mesh, solar panels, metal satellite dishes, cinder block can interfere with RF. Because
of RF interference, DO NOT IN TALL transmitters or repeaters on metal siding, inside of metal
boxes, on the surface of metal boxes, or in metal lined rooms like walk-in coolers or freezers.
•ome modern windows with built in resistance to solar gain use materials which may interfere
with RF.
•Vegetation can interfere with RF. The transmission environment changes when leaves are on
the trees and when they have fallen off.
•Hills and earthen berms can absorb or deflect a lot of RF. Try to minimize the number of
obstacles between the transmitters and repeaters or the NoWire receiver.
•Auto and truck traffic. If there is a busy road or a truck parking lot between transmitter and
repeater, the signals may at times bounce off the vehicles.
•People usually don’t bother RF from passing.

8.2.3.4 Frequency Hopping
The wireless system has been designed to effectively deal with RF blocking. ince the transmitters are
mandated to be low powered, the transmission environment constantly changes, and barriers come and
go, not all of the transmissions from the transmitters may be received at the NoWire receiver. To
counteract these effects, the NoWire system uses a technique called frequency hopping. This
means that messages are sent more than once on separate frequencies. Frequency hopping is also
known as spread spectrum. In the following illustration, narrowband means that the signal is sent over
one frequency. In spread spectrum, the same message is sent over multiple frequencies.

8.2.4 Wireless System Planning
You must determine if NoWire will need repeaters to get the transmitter signals to be received by the
NoWire receiver. For smaller installations you may not need repeaters if the transmitters are within a
few hundred feet of the NoWire receiver or even further if there are few or no obstacles. For larger
spread out installations you will need to determine where repeaters need to be placed. Here is an
example of a multi-family property with marked repeater locations.
8.2.4.1 Determine if repeaters are necessary
To determine if repeaters are necessary you may utilize NoWire with an EN1501 transmitter in fast
mode. By moving the EN1501 transmitter around to your meter locations while transmitting in fast
mode you may read the transmitter signal level to determine first if it is seen by NoWire and, if so, is the
signal level strong enough.
•Locate NoWire where it will be installed and apply power.
•Using the setup menus assign an EN1501 transmitter to a wireless input point if not already
assigned.
•Open the EN1501 case and press the tamper spring down 3 times within 10 seconds. This will
put it in fast mode and transmit once every minute. The transmitter will stay in fast mode for 3
days, or until the reset button is pressed. NoWire will display a status code of “F” when it
detects the transmitter in fast mode.
•Locate the transmitter in the desired test location.
•Using the setup menus for the assigned wireless input point scroll to the “Xmitter Rcvd” setup
screen. This will indicate the date and time it last received a transmission. This will
automatically update with each reception of a message from the transmitter. tay on this
screen for a few minutes and verify the transmitter message is received every minute.
•Continue to scroll through the setup menus to the “Xmitr Levels” setup screen. If the Level is
greater than 4 then the signal is strong enough. Note: You may wish to stay on this screen for a
while until the Level value settles to its final value. If it was strong when it was first received
then it may take some time before the true level is established.
