1 Introduction
This manual describes how to install, test and service a Gateway. The Gateway is
part of the Level Monitoring System, which includes the Gateway, up to 40 Level
Monitors (hereafter referred to as Monitors), and a Data Center that provides the
user interface.
This manual does not include how to install, test, maintain, or troubleshoot the
Monitors. Refer to the individual Monitor Instruction Manuals for this information.
The Outdoor Gateway is to be installed as fixed, permanently connected
equipment. This means that the Gateway should be fastened to a support and
electrically connected to its supply by a permanent connection.
2 Product Overview
2.1 Description
The Gateway consists of a transceiver that collects Monitor information and either a
cellular modem or Ethernet port that relays this information to a centralized data
collector.
2.2 Operation
The Gateway can receive Radio Frequency (RF) signals from up to forty Monitors.
The Gateway communicates with the Data Center using a cellular or Ethernet
connection. The Gateway sends data and can receive commands, setup
information, and firmware upgrades from the Data Center.
The Level Monitoring System utilizes 2.4 GHz ISM band communications in
accordance with the Federal Communications Commission (FCC) rules.
The Gateway is powered by a DC supply, depending on the model ordered. A
terminal block or spade terminal (depending on model) inside the Cellular Gateway
housing is provided for connecting to the power source.
2.3 Environmental Specifications
The following environmental specifications should be observed when installing the
Gateway:
Ambient Temperature Range:
oOutdoor Models: -30C to +60°C
oIndoor Models: 0C to +60°C
CGW-0 Models designed for outdoor use (Raintight) provided that the
conduit connections are made in a way that maintains this level of
protection.
CGW-1 Models designed for indoor use only.

2.4 Certifications
This equipment contains a radio module and a cellular modem that comply with
Part 15 of the FCC Rules.
3 Installation
3.1 Gateway-Monitor RF Site Guidelines
The Gateway should be mounted in accordance with Section 3.2 and the location
should be selected in accordance with the following guidelines:
Direct line of sight between the Monitor and the Gateway will provide
optimum radio reception. Optimal orientation would have the Gateway
antenna oriented towards as many of the installed Monitors as possible.
The Monitors would ideally be oriented so that the label with the serial
number faces the Gateway.
The Monitor and the Gateway can communicate at distances up to one
mile under optimum line-of-sight conditions.
When obstructions such as walls, buildings, chain link fences, and vehicles
exist between the Monitor and the Gateway the distance between these
units should be limited to less than 500 feet.
Multiple obstructions (such as two or more walls or a tank and a wall)
should be avoided, if possible.
Electrically conductive objects, such as metal buildings, concrete
reinforcing rods, tanks, silos, and vehicles reflect radio signals. This
reflection can be either an advantage or a disadvantage to good radio
reception at a particular installation site:
1 Metal objects between the Monitor and the Gateway may reflect and
scatter RF energy and reduce radio signal strength at the Gateway.
2 Metal objects behind the Monitor or Gateway may increase the radio
signal strength at the Gateway by reflecting radio signals toward the
Gateway.
Even small objects such as tank vents or toolboxes between the Monitor
and the Gateway can significantly reduce radio signal strength if they are
within a few feet of the Monitor or Gateway. These objects can reflect
radio signals and cause an RF “shadow” which may prevent radio signals
from reaching the Gateway.
Objects which are not electrically conductive such as wooden or fiberglass
buildings, non-reinforced masonry, trees, plastic, and glass have less
effect on radio signals than metal objects.
Windows and wooden doors can provide radio signals access to otherwise
closed metal buildings. However, “low-E” window glass may have a thin
metallic coating that can reflect radio signals.
Gateway Instruction Manual
Page 6
Strong electromagnetic fields such as those found in close proximity to
power lines, large electric motors, generators, electric fences and
transmitter antennas may interfere with the radio signal received by the
Gateway.
The Gateway should be mounted as high as is reasonably possible to
improve its ability to receive radio signals. For example, placing the
Gateway high on a wall would be preferable to mounting at a low level.
Installing the Gateway in an underground basement should be avoided.
Mounting the Gateway so that it has an unobstructed view of the horizon
will improve cellular communication.
3.2 Gateway Site Guidelines
Outdoor models of the Gateway are housed in a polymer enclosure designed for
mounting on a vertical surface. The enclosure is provided with four (4) small
mounting brackets. It is intended that the Gateway be mounted with the wire
entrance on the bottom.
Indoor models of the Gateway can be mounted either on a horizontal or vertical
surface.
Reference Installation Drawing at the end of this manual.
3.3 Antenna Mounting
The Gateway is supplied with an external mount antenna. Mounting the antenna in
the vertical position provides the best RF performance.
With the antenna in the “L” position and already in the vertical position shown
below, hand tighten the SMA connector of the antenna onto the gold connector
protruding from the enclosure until snug. Do not use a wrench or pliers on the
antenna connector or the interior hex head.

A readily accessible disconnect device shall be incorporated in the supply wiring.
3.4.1 Supply Power
The outdoor models of the Gateway enclosure are supplied with two holes for 3/4”
conduit in the bottom of the enclosure. The installer must use the proper fittings to
maintain the weatherproof integrity of the enclosure. The manufacturer does not
recommend adding additional holes to the enclosure. However, if additional
holes are added, proper Type 4 seals must be used to prevent water from
leaking into the enclosure.
The indoor models of the Gateway are supplied with two bushings installed for the
user to connect DC supply and the Ethernet cable (if used for your model).
The Gateway is a Category II device.
The outdoor models of the Gateway require an external SELV source of 12-24V
DC.
The indoor models of the Gateway require the use of a 12 – 24V DC supply.
The wiring must be in accordance with any national, state and/or local regulations.
This equipment is considered Class 1 which uses a protective earth ground.
Verify that the cables from the cover to the printed circuit board are properly
connected. Close the cover and secure the two latches.
Fuses F1 and F2 are permanently soldered on the PCB. They are installed only for
catastrophic failure and are not considered serviceable by an end user. The
connections for this power are located as follows:
Warning: Remove all power to the board before opening
the enclosure for service. Electric shock or
deathcouldoccur.
Avertissement: Enlevez tout le pouvoir de la planche avant
d'ouvrir la clôture pour le service. Le décharge électrique ou
la mort pourraient se produire.

3.5 Setup
Prior to applying power, the Gateway must be added to the Data Center (including
adding the Gateway and Monitor serial numbers into the database).
3.5.1 Cellular Gateway Setup
There are no extra cables for the Cell Gateway.
If your cellular modem was not factory provisioned or activated on a network then
follow the special instructions located in the appendix under Advanced Setup.
3.5.2 Ethernet Gateway Setup
Using an Ethernet cable, connect the Controller to a port on a network switch or
hub or any standard RJ-45 network jack where a computer could gain access to the
Internet. Longer Ethernet cables may be used, if necessary, but the total cable
length includingpermanent wiring inside the building should not exceed 300 feet.
The Gateway will connect only to the Data Center and no inbound port forwarding
rules should be required on the customer’s network firewall.
If the local network requires a static IP address,then follow the special instructions
located in the appendix under Advanced Setup.
3.6 Activation
Following wiring and setting up the Gateway, the unit can be activated by turning on
the supply power. When power is applied, the Gateway will enter a short test mode
and the two lights on the front of the housing will cycle from off to the color Yellow.
The Gateway will then enter an initialization phase, which may take several
minutes, during which timeData Center light will blink Yellow or Green. Once the
Gateway has communicated with the Data Center, it will enter normal operating
mode and the Data Center light will turn solid Green. The status indicator lights can
be interpreted as follows:
Caution: Risk of Explosion if battery is replaced by
an incorrect type.Dispose of used batteries
according to the instructions.
Prudence: Le Risque d'Explosion si la batterie est
remplacée par un type incorrect. Débarrassez-vous
