Introduction
• The Wireless solution cannot extend communications between Gasboy devices [such as Island
Card Readers (ICR), 9800 series pumps, Gasboy Pump Control Units (PCU)], and other
manufacturer electronic pumps. Also, it is not intended to be used for credit card network
communications.
• The Wireless solution is only intended for point-to-point communication between one PC and
one Gasboy Fuel Management System (FMS) at a time. Multiple Gasboy FMS systems will
require one Base Station kit and one Fueling Position kit for each point-to-point wireless
communication link. An RS-232 A/B has to be locally supplied to switch between the multiple
base stations and Gasboy FMS systems.

This is a 15-foot CAT-5 Cable with gender menders at each
end to interface the PC to the Modem Interface Board.
• The distributor is responsible for supplying, and properly installing the towers,
masts, or mast mounting brackets.
• The manufacturer's installation manual MUST be followed.
• Up to a 28-foot tower can be installed at the Gasboy system end without the use of
guy wires. This can consist of a 10-foot tower and a 10-foot mast for a total of 18
feet, or a 20-foot tower and a 10-foot mast for a total of 28 feet.
• The height of the tower is to be determined by the line of sight requirements of the
antenna located on the top of this tower or mast, to the PC wireless modem and its
antenna at the top of its mast or tower.
• An appropriate base plate/mounting bracket to support the tower may be sourced
from one of the following:

Site Installation Review and Considerations
Parts Explanation
Mast or tower at the PC end • Usually, a building mast bracket will be used at the PC end for the wireless modem
antenna. This bracket must be mounted such that the antenna is above the roof
line of the building it is attached to.
• Usually, you can install a 10-foot mast which gives an 8-foot height increase from
the point of mounting. Masts taller than 10 feet generally require the use of guy
wires for support.
• If an appropriate mounting to the side or top of the building cannot be located, a
tower may be used.
Coaxial cable and
connectors used between
wireless modem enclosure
and antenna
Conduit If the Gasboy system is not a pedestal mounted TopKAT, conduit from the system
Ground Rods and Ground
Wires
• Gasboy requires the use of RG8 or RG8U coaxial cable. Belden 7810 or its
equivalent meets the Gasboy cable loss requirement. If you are using Belden
7810 or its equivalent, it is recommended that cable lengths do not exceed 150
feet (45.72 meters).
Note: Ensure that the drip loops are provided on all the coaxial cable runs. These
should be provided in such a manner that all connectors, antennas, wireless
modem enclosures and the accesses to the building have a drip loop
installed.
to the wireless modem must be supplied.
• Each tower requires a dedicated ground rod located as close as possible to the
tower or mast.
• The tower and the wireless modem enclosures ground lug for that particular end of
the wireless communication loop MUST be connected to that particular ground rod
only.
• The installed ground rod is connected to the tower or mast and to the wireless
modem enclosure ground lug with a ground wire not less than AWG #4.
Site Installation Review and Considerations
At the PC End or the Building End of the Wireless Communications Loop
Ensure the following for wireless modem placement and coaxial cable runs:
• PC power and wireless modem power MUST come from the same AC circuit. The
wireless modem operates in the 900 MHz range, which is in the same range as some
cordless phones and cell phones. It is recommended not to have a 900 MHz spread
spectrum phone base in the vicinity of the wireless modem enclosure.
• Gasboy provides a 15-foot RS-232 communications cable from the PC to the Wireless
modem. This RS-232 cable can be extended to 50 feet only (15.24 meters) and ONLY in
the metal conduit. Cable shield integrity must be maintained if the cable is extended.
• From the wireless modem enclosure to the antenna, you can run RG8/U coaxial cable to
the antenna. During the length of this cable run, it MUST not be run along with or bundled
to AC conduits, CAT-5, or phone line wires. It may cross over these wires at 90 degrees.
• The antenna must be above the roof line and cl ear of obstructions. This antenna must have
a line of sight view of the antenna mounted at the Gasboy system end of the wireless
communication loop.
• A standard building wall mount mast bracket will only give an 8-foot rise without the use
of guy wires. Gasboy recommends the use of the wall mount at the building so as to not
penetrate the building roof. In Northern climates, ensure that the antenna is placed well
above the roof line so that it does not get buried by snow accumulation.
• Currently, you must have one modem at the polling PC for each modem attached to a
Gasboy system (except TopKAT Online). For example, if you have two Series 1000
systems that can be polled from the same PC, you will need two wireless modems at the
polling PC and two antennas.

At the Gasboy System End
Note: The fueling position assembly must be mounted no lower than 18 inches above the
ground and no closer than 18 inches to any fuel dispenser.
Antenna Mast or Tower
• The height of the mast or tower will be determined by the line of sight requirement
between this antenna and the PC wireless antenna.
• You are allowed to use a 10-foot mast, or a 10-foot tower and 10-foot mast (11 feet to 18
feet total height), or a 20-foot 1 or 2 section tower and 10-foot mast (21 feet to 28 feet total
height) without the use of guy wires.
• If a tower base section is used, the manufacturers’ requirements for the installation of that
tower must be followed for the height of the tower installed.
Note: A tower and mast section is preferred as it encloses the wireless modem insi de the
tower and protects it from being damaged.

Connections between the Wireless Modem and a TopKAT Unit
For an installation with a TopKAT unit mounted on a dispenser, connect five of the wires from
the dispenser DC conduit directly to the port (green connector) and connect two others to the
red and black wires on the M06543A001 cable (
M06543A001 cable should be cut short enough so that excess cable is not left in the TopKAT
unit.
If the T opKAT unit is mounted on a 9850 dispenser (that has only six wires in the DC conduit),
connect the black wire from the power supply connector together with the wire connected to
pin 5 of the port connector (green connector). At the modem end, connect that wire to position
5 of the modem terminal block and jumper positions 5 and 7 together.
