2.1 Pre-Installation
This section provides information about Wireless Petro-Net Modem requirements and restrictions for proper
installation.
2.1.1 Installation Restrictions and Requirements
NOTE:
l Some sites might NOT be suitable for Wireless Communication.
l Avoid metal buildings; the wireless modem will not communicate through metal
buildings.
l Locate the modem near a window.
l Mount the antenna on the outside of the building.
l 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-OFSIGHT from antenna to antenna.
Page 8 of 43
IMPORTANT: Improper operation due to poor installation planning is not covered under
warranty; it is your responsibility to verify the suitability of the wireless application.
2.1.2 Conduct a Site Survey
Before you decide to install the Wireless 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:
l Transmitting element
l Receiving device
l The environment through which communication is occurring; and
l Antennas or other focusing elements
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:
l Visual LOS is the ability to see from one site to the other. It requires only a straight linear path between
two points.
l 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.
Page 9
Doc. No.: M00-20-7074 Rev.: 6
Figure 2-1 Fresnel Zone
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.
Page 9 of 43
Figure 2-2 Antenna Height O ver Physical 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.
NOTE: OPW does not recommend a distance greater than 5,000 feet (1524 m).

Doc. No.: M00-20-7074 Rev.: 6
Page 10 of 43
In order to have ground clearance, the combined antenna height should be equal to the diameter of the
Fresnel Zone.
Increased 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 wirelesscommunication 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)
l 2.1 dBi (0 dBd) = 75º VBW
l 5.1 dBi (3 dBd) = 33º VBW
l 8.1 dBi (6 dBd) = 17º VBW
Directional antennas focus energy more specifically in one direction.
Gain vs. Vertical Beam Width (VBW)
l 8.1 dBi (6 dBd) = 70º VBW
l 11.1 dBi (9 dBd) = 55º VBW
l 15.1 dBi (13 dBd) = 35º VBW
Page 11
Figure 2-3 Omni-Directionaland DirectionalAntenna SignalPatterns
NOTE: Notice how, like the flashlight, the beam width is decreased as gain is increased.

Antenna Installation 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.
TIP: If you have two (2) wireless modems, you do not have to configure the modems and you
can proceed with the installation instructions. The modems are pre-configured for use with one
(1) or two (2) modems.
NOTE: If you have three or more wireless modems, please refer to "FSC to Multiple FIT
Operation (3 or More Wireless Modems)" on page24 for setting up multiple modems.

Figure 2-4 Remote DirectionalAntenna
2.2.4 Multiple FITs (Networking)
In cases where you have multiple FITs you can set up the antennas to send signals from one FIT to another.
Up to seven (7) sets of modems can operate independently in the same area.
The Networking > HP Command is used to set the modem’s hopping channel number. In order for
modems to communicate with each other, the modems must have the same channel number since each
network uses a different hopping sequence. Different channels can be used to prevent modems in one
network from listening to transmissions of another. For example, you could set system A to HP 1 and system
B to HP 5. You can use the channels between 0 and 6. The wireless modem comes is set at 0 by default.
2.2.5 FSC with Remote Antenna (Recommended by Manufacturer)
In areas where line-of-sight is blocked to the FSC, you can use a remote antenna. For example, the antenna
can be placed on top of the building so that it is in line-of-site with the antenna on the FIT. When determining
where to place the antenna, remember to avoid all current and possible future obstructions.
1. Attach the 20-foot antenna cable to the modem.
2. Route the cable to the remote antenna.
3. Mount the antenna to a pole or suitable surface using the hardware provided.
4. Power the modem by plugging the power supply into a wall outlet.
2.2.6 FSC with Remote Modem
In areas where the FSC does not have a direct line-of-site with the modem and the antenna cable is too short
it is necessary to use a remote modem.
1. Extend the Petro-Net cable to position the modem where desired (1,000 feet maximum).
2. Mount the modem in a secure location (or enclosure) and attach the 20-foot antenna cable to the
modem.
3. Route the cable to the remote antenna.
4. Mount the antenna to a pole or suitable surface using the hardware provided.
5. Power the modem by plugging the power supply into a wall outlet.
2.2.7 FSC with Modem-Mounted Antenna (Not Recommended)
The antenna at the FSC can be mounted directly on the modem. This modem must be in the line-of-site with
the antenna at the FIT (i.e. must be near a window).
2.2.8 Automatic Tank Gauge Console
A wireless modem is connected to the VSmart Module to provide wireless communication option between the
VSmart and the . The wireless modem should ideally be placed in an area where there is line-of-sight to the
Console. Another modem is then wired to the Integra console’s RS-485 port.
NOTE: The Wireless option will not communicate through metal buildings.

NOTE: It is recommended to fill out an Integra Site Survey (M00-2027) before doing a
wireless Petro-Net installation. This can help identify possible interference problems.
2.2.9 Communication
After determining the range of the modems, you can permanently install and wire the remote station modem.
Polarity is critical with all RS-485 communications. Petro-Net Terminal 1 goes to pin 8 on the modem, and
Terminal 2 goes to pin 2 on the 9-pin modem connector. Both modems are wired the same. Use the supplied
Petro-Net connector; connect the black wire to #1 on the Petro-Net Terminal and the white to the #2
Terminal.
IMPORTANT: RS-485 (Petro-Net) polarity is critical!
Pre-wired Petro-Net Connector

Page 17 of 43
2.2.10 FIT Wiring
The FIT must be powered by a dedicated circuit. The FIT cannot be powered by the pump circuit or reset, as
communication problems will occur. The system warranty is void if this is not followed.
FIT Installation Location Wiring
NOTE: See "Terminal Connections to Console" on the next page.
1. Place the modem inside the FIT.
2. Connect the modem power pack to line voltage using the pigtail supplied.
3. Petro-Net: Use the supplied Petro-Net Connector and connect the black wire to #1 Terminal and white
to the #2 Terminal.
4. Drill a .375-inch hole for the antenna cable in the bottom of the FIT cabinet.
REMINDER: When drilling through the pedestal, make sure to clean up all metal chips.
5. Route the 1-foot cable from the modem to the antenna location. (Seal this hole with silicone sealant).
Be sure to maintain line-of-sight to the FSC.
6. Drill a .250-inch hole in the pedestal and attach the cable to the pedestal of the FIT and secure with the
supplied nut.
7. Attach the antenna cable.
For remote antenna mounting, attach the directional antenna to a pole or other surface using the supplied
mounting brackets. Antenna cables are available in 20-foot lengths. When mounting the antenna remotely be
sure to protect the antenna cable with conduit.
IMPORTANT: Always keep in mind where the fuel island (remote) modem is! You must
maintain a line-of- sight with the remote modem for best results.
2.2.11 FSC Installation Location Wiring
1. Place the modem on a table or shelf near the fuel site controller.
2. Plug the power pack into a wall outlet. Connect the cable from the power pack to the modem.
The indoor modem comes with a 6-inch antenna, for some applications this will work fine. When choosing a
location, keep the REMOTE modem (at the fuel island) in mind. The modems communicate better when they
are "in sight" of each other. If you experience problems, move the modem until reception is better.
3. Use the junction box cover to make the connections at the FSC. Petro-Net wire can be used to remote
either modem for best performance. Limit the wire length to 1,000 feet.
In some cases, the directional remote antenna and 20-foot cable should be used to improve communications
to the FSC when installed in metal buildings or other areas which may have poor signal strength.

4.4 Troubleshooting
Performing a range test will give an initial indication of the expected performance. If the loopback test
indicates that additional range may be required, ask the following questions about the installation:
Do I have clear RF line-of-sight?
If the Fresnel Zone is not clear of the ground or other obstructions, often the best way to improve range is to
raise the antennas higher off the ground to help transmit over vegetation or other obstacles.

What frequency am I using?
The Wireless Modem comes in two varieties: 900 MHz and 2.4 GHz. The 900 MHz waves penetrate objects
and travel better than their 2.4 GHz counterparts. If you are in the U.S., Canada, Australia or Israel, you are
using the 900-MHz radios. The 2.4-GHz radios must be used in European countries and where the ETSI
standard is required.
Can I use a directional antenna?
Directional antennas will have better gain than the omni-directional antennas. While the omni-directionalgain antennas can improve performance in line-of-sight applications, the performance in non-line-of-sight
situations is very similar to a dipole. If you need to maximize range, using a gain antenna may be the best
solution.
Is the antenna mounted properly?
Using long antenna cables or having the antenna right next to metal can reduce performance. Antenna
cables add loss to a system. Using a shorter antenna cable can help keep the losses to a minimum. Often, a
longer serial data cable can be used in conjunction with a shorter coaxial cable to keep antennas in a
desired location. The radiating portion of the antenna should not touch other metal objects or be mounted
right next to them.

This can cause the antenna to operate inefficiently. It is best to allow at least several inches of separation
between the antenna and other metal structures or objects.
