1. Introduction
Figure 1-1 Wireless Modem
These instructions explain setting up the modem hardware, testing the range of the radio link, some advanced
(but optional) configuration possibilities and some tips for better operation.
Some installations may not be suitable for Wireless Communications. Contact OPW-FMS
technical service for site survey and testing information if you are unsure of your potential
installation site.
1.1 Overview
Your wireless modem can be used in many applications, including:
Sites that cannot be connected by conduit, sites that contain obstructions, roads, railroad tracks,
water, etc.
Property with dig restrictions
Locations with thick, reinforced concrete, such as airports, or trucking and military installations
Up to seven (7) wireless modems can communicate within the same network.
1.2 Wireless Modem Kit
The Wireless Petro-Net Modem®works with the following systems:
K800™ (software 1.09 or higher)
K800™Hybrid®
System2®
C/OPT®
FSC3000™
SiteSentinel®iSite™
The standard kit includes:
Radio modems with 6 in (152.4 m) antennas
Petro-Net connectors
Two (2) directional antennas
Two (2) 20 ft (6.1 m) antenna cables

2. Pre-Installation Considerations
This section provides information about Wireless Petro-Net Modem requirements and restrictions for proper
installation.
2.1 Installation Restrictions and Requirements
IMPORTANT! Please Read....
Some sites may NOT be suitable for Wireless Communication.
Avoid metal buildings; wireless Petro-Net will not communicate through metal buildings.
Locate the modem near a window.
Mount the antenna on the outside of the building.
Keep the path to the receiving modem clear. If vehicle traffic at the island blocks the view of the
receiving modem, you must reposition the antenna to maintain LINE-OF-SIGHT from antenna to
antenna.
Note: Improper operation due to poor installation planning is not covered under warranty; it is
your responsibility to verify the suitability of the wireless application.
2.2 Conducting a Site Survey
Before you decide to install the Wireless Petro-Net Modem, you must first make sure that it will work at the
desired location. Communication systems have several components that should be looked at in each system:
Transmitting element
Receiving device
The environment through which communication is occurring; and
Antennas or other focusing elements
2.2.1 Environment
The space between the transmitter and the receiver is the system’s environment. This will be the main focus of
your site survey. Physical obstructions and noise (interference) can enter into the environment and limit the
system’s ability to get information from one place to another.
Attaining RF Line-of-Sight (LOS) between the sending and receiving antennas is essential in achieving a
reliable signal between the FIT and the FSC. There are two types of LOS that are generally used to describe
an environment:
Visual LOS is the ability to see from one site to the other. It requires only a straight linear path
between two points.
RF LOS requires not only visual LOS, but also a football-shaped path, called a Fresnel Zone, free
of obstacles for data to optimally travel from one point to another.

In order to achieve the greatest range, the Fresnel Zone must be free of obstructions. Buildings, trees or any
other obstacles in the path will decrease the communication range. If the antennas are mounted just barely off
the ground, more than 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 is also important to understand that the environment may change over time due to growing vegetation,
building construction, etc. If obstacles exist between two points, the antennas can be raised on one end or on
both ends to clear the Fresnel Zone of obstructions.
How far above the ground and other obstacles the antennas need to be is determined by the diameter of the
Fresnel Zone. The diameter of the Fresnel Zone depends upon the frequency and distances between the two
radios. Various data points were inserted into Fresnel Zone formulas to provide some points of reference. The
following table provides approximate Fresnel Zone diameters at 1,000 ft (304.8 m) and 1-mile (1.6 km) ranges.
OPW does not recommend a distance greater than 5,000 feet (1524 m).

Table 2-1 Fresnel Zone Diameters
Range Distance

(900 MHz Radios)
Required Fresnel Zone Diameter
(2.4 GHz Radios)
1000 ft. (300 m)
16 ft. (7 m)
11 ft. (5.4 m)
1 mile (1.6 km)
32 ft. (12 m)
21 ft. (8.4 m)
In order to have ground clearance, the combined antenna height should be equal to the diameter of the Fresnel
Zone.
2.2.2 Increasing Antenna Gain
Transmitting and receiving antennas are used to focus and direct radio waves in specific directions. Antennas
are another component that can be adjusted to increase the distance data can travel in a wireless-
communication system. Antenna gain is an important variable that can be adjusted in order to increase range.
Antenna gain describes the amount of focus the antenna is able to apply to the system by directing the energy.
The more focus the antenna can apply, the more range the system will yield. High-gain antennas can achieve
greater range than low-gain antennas, though they cover less area.
Omni-directional antennas focus energy evenly in a doughnut-shape around the antenna.
Gain vs. Vertical Beam Width (VBW)
2.1 dBi (0 dBd) = 75º VBW
5.1 dBi (3 dBd) = 33º VBW
8.1 dBi (6 dBd) = 17º VBW
Directional antennas focus energy more specifically in one direction.
Gain vs. Vertical Beam Width (VBW)
8.1 dBi (6 dBd) = 70º VBW
11.1 dBi (9 dBd) = 55º VBW
15.1 dBi (13 dBd) = 35º VBW
Notice how, like the flashlight, beam width is decreased as gain is increased.

2.2.3 Mounting Considerations
When mounting an antenna, care should be taken to make sure it is as far away from metal objects as
possible. If nearby metal gets too close to an antenna, it has the potential to interfere with the way the antenna
radiates and may cause some undesirable results.
In some cases, a cable must be used to connect an antenna to a transmitter or receiver. All RF cables add
some loss to the system. For any given cable, the longer the cable the more signal will be lost over that cable.
Because of this the length of the cable should be kept as short as possible. Often a longer serial cable can be
used to minimize the length of the antenna cable.
If you have two (2) wireless modems, you do not have to configure the modems and you may
proceed with the installation instructions; the modems are pre-configured for two (2) or less
modems.
If you have three or more wireless modems, please refer to page 26 for setting up multiple
modems.

3. Typical Installations for the Wireless Petro-Net Modem®
This section covers the various mounting and wiring instructions for typical Wireless Petro-Net Modem®
installations.
3.1 Typical Installations
The Wireless Petro-Net Modem®can be set up to work with various installations:
SiteSentinel®iSite™
FIT with Remote Antenna
Multiple FITs
FSC with Modem-Mounted Antenna
FSC with Remote Modem
Check with local authority for suitability of installation.
FSC with Remote Antenna
3.2 FIT-Mounted 6 in antenna
FIT-Mounted 6 in antenna is not suitable for all applications
When setting up the Wireless Petro-Net Modem®, you can install the antenna directly onto the FIT.
1. Connect the power supply to the power terminals in the FIT.
2. Place the modem on the bottom of the FIT.
3. Locate and drill a .375-inch hole for the antenna cable, seal this hole with silicone sealant.
4. Locate a position on the pedestal to install the antenna, drill a .25-inch hole for the connector.
5. Remember to keep line-of-sight with the FSC antenna, (e.g. this cannot be blocked by vehicle traffic at
the island) otherwise proceed to FIT with remote antenna mounting.
Figure 3-1 FIT-Mounted Modem Power Supply
6. Locate the power supply behind the main board.
7. Connect the power cable to the power connector on the system.
8. Connect the Petro-Net cable at this time. (Black wire to Terminal 1; White wire to Terminal 2).
