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’s antenna and the location
of the concentrator’s antenna.
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.
