1 Introduction
The Gal2Way system, also known as the G2W system, is a radio system which is used to control and
monitor field units which are far away from the Galileo controller, utilizing latch outputs, as well as
analog and discrete inputs.
The Gal2Way system is another great addition to the Galcon Ag line of products.
Technical Overview
The G2W system consists of the following components:
Galileo Controller
Concentrator.
Repeaters.
Field units. The G2W system supports the following types of field units:
Galcon RTU.
G2W4.
G2W8.
Communication between these components is performed by two-way radio communication through
antennas which are connected to each component via RF cables.
G2W operates at  MHz frequency, which is a free frequency (ISM).
For more detailed information, refer to System Components on page 9.

2 System Components
The G2W system consist a number of main components:
Field units Installed in the field next to the valves, the field unit transmits the states of the various
inputs to the controller and gets commands from the controller through the concentrator.
Repeaters Used as intermediate stations between the units and the concentrator in cases of where
direct communication is not possible, such as when the field unit is more than 2 km from the
concentrator, or when communication is blocked by obstacles.

Field Units
The G2W system supports the following types of field unit:
Galcon RTU.
G2W 4.
G2W 8.
Field units are intended for outdoor use, operating at an ambient temperature range of -10o C to +50o C,
and at a maximum relative humidity up to 100%. The Ingress Protection of the field units is IP54.
Galcon RTU Field Unit Features
The Galcon RTU field units have the flowing input and output ports:
4 x 3 wire DC latch output ports.
8 x Discrete input ports.
3 x Analog 4 -20 mA / 0 -10 V input ports.
The analog input ports can operate at a voltage range of 0-10 V, or a current range of 4-20 mA. To define

Field Units Power Supply
The field units are powered by four 1.5V D-size alkaline batteries, which are inserted into the battery
compartment. The field units can alternatively be powered by an external solar panel and charged
batteries or an internal battery. Contact Galcon to request these alternative components.
Note: Galcon RTU field units do not supply power to the connected sensors. When
connecting sensors to the analog inputs or when transmitting data to the digital inputs you
must supply an external source of power for them.
Field Units Connection
The field units can be connected to two antenna types in various combinations in order to achieve
variant communication transmission strengths. Connect each field unit to its antenna(s) with RF cables.
Do not bend the cables below a radius of 30 cm. Always keep a 60 cm distance between any two
antennas.
The various combinations below are listed according to increasing communication transmission strength:
Single 916-CW-HW antenna.
Two 916-CW-HW antennas.
916-CW-HW antenna & FG9023 antenna.
Two FG9023 antennas.
Repeater (Relay)
The repeater unit is used when the communication between a field unit and the concentrator is weak, or
when the field units are installed in locations where obstacles interfere with radio communication
between the field units and the concentrator.
The repeater is designed for installation in the field without the need for an external power source. For
this purpose, it includes both a solar panel and charged batteries.
Repeater Connections
Connect the repeater unit to two FG9023 antennas with RF cables. Do not bend the cables below a
radius of 30 cm. Always keep 60 cm distances between antennas.
Concentrator
The concentrator acts as the system manager. The concentrator transmits, via radio communication, the
commands to all the field units, and returns the various inputs of the field units to the
controller. The concentrator is connected to RF antennas and cables. The concentrator is equipped with
a backup battery which lasts for at least 24 hours.

G2W –Gal 2 Way –Installation and Operation Guide
12
The concentrator can be installed in one of two ways:
Installed close to the controller, at a distance of not more than 10 meters, using direct
communication (RS-232).
Installed at a distance of not more than 30 meters, using an RS-485 adaptor.
The concentrator is intended for outdoor use, operating at an ambient temperature range of -10o C to
+50o C, and at a maximum relative humidity up to 100%. The Ingress Protection of concentrator is IP54.
Concentrator Connections
Connect the concentrator to two FG9023 antennas with RF cables. Do not bend the cables below a radius
of 30 cm. Always keep 60 cm distances between antennas.

Radio INT Adaptor Card (AC0117)
The I/O adaptor card (AC0117), known as the Radio INT card, enables the controller to perform
communication between the controller and the concentrator.
Note: The card does not supply power to the concentrator.

3 Registering System Components
All the field units and repeaters in the system need to be registered in the concentrator. This registration
process is performed on the concentrator; there is no need for any registration process on the controller.
Connecting or disconnecting the controller will not affect the registration process.
Notes:
It is recommended to position all the field units and repeaters near the concentrator
while performing registration. This maximizes the communication strength between the
units and facilitates successful registration.
Upon performing registration, each field unit and repeater unit downloads its default
configuration settings from the default values defined in the concentrator. You may
want to modify these default settings in the concentrator before performing
registration. For more information, refer to Configuring Field Units and Repeaters on
page 31.

4 Installing the G2W System
Pre-Installation Planning
Before installing the components of the Gal2Way system, make sure to examine the installation
environment to determine the best locations for installation.
You must make sure to install components above obstructions which may interfere with the RF
transmissions between components. All components must be installed such that there is line-of-sight
between all component antennas.
Verify that there is a direct line-of-sight between the location of the unit and the location
of the .
Make sure that the distance between the field unit and the concentrator does not exceed 2 km.
Field unit antennas are to be installed on poles which are not less than 2 m high. Verify that there are
no obstructions which are more than 2 m high between the field unit and the concentrator.
If there is a significant obstruction between a field unit and the concentrator and no better location
can be found, you may be able to install a repeater (relay) to serve as an intermediary.
For the repeater, you should find a location which has line-of-sight, without significant obstructions,
and is within 2 km of both the concentrator and the field unit.
Notes:
In order to achieve the maximum results with the fewest repeaters, place the repeaters
in locations which support the maximum number of units. The system can support up to
four repeaters.
The system does not support chains of repeaters.
Installing the Concentrator
The appropriate location for installing the concentrator is determined according to the communication
type used:
When direct communication (RS-232) is used, the installation should be next to the controller, at a
distance of up to 10 m.
When using an RS-485 adaptor, the installation can be further away, at a distance of up to 30 m.
The concentrator should be positioned so that the communications and voltage cable will reach the
controller.
Affix the concentrator to the wall by inserting screws through the holes in the aluminum plate at the
back of the box.

Figure 6: Installing the Concentrator
Connecting the Concentrator to an External Power Supply
The process of connecting the concentrator to a power source depends on whether you are installing a
DC or an AC unit:
DC-operated Concentrator Connect a power supply of 12V DC to the correspondingly labeled
connector.
AC-operated Concentrator Connect the supplied power supply unit.
Note:
power supply of 9V 700mA AC
-The concentrator includes an internal backup battery which lasts for at least 24
hours.
Note:
The concentrator should be located within shelter for direct, initial
Protection from effects of the weather
