5.1.6 A Star/Chain combination works well in agriculture.
Agricultural eld variation as above can easily be handled by the TD200 controller because
wireless routing is designed to t all shapes. The Star/Chain combination routing shown above can
handle some valves close together and some long distances away. Some TWIGs can be setup to
communicate directly to the controller and others can be setup to work through TWIG-Repeaters.
Each TWIG must be located within line of sight range to each TWIG-Repeater. The signal transmitted
from the TWIGs back to the controller must be checked because it is sent from internal antennas that
are not as strong as the repeater antennas.
Figure 5.4
Example of a TWIG Repeater solution: In this example of an orchard/vineyard it was
observed that the distance between the TD200 and valves 8, 9, 10, 11 and 12 exceeded the range.
The signals were weak. A chain was set up by adding repeater ‘R1’ which was needed to bridge
the distance between the TD200 and valve 8. The other weak valves still had weak signals. So
repeater ‘R2’ was added. As soon as that was done then TWIGs numbered 8 through 12 were linked
automatically into the network chain through the repeaters to get a strong signal from the TD200
controller. Repeaters can be located at any convenient place. Here the repeaters were placed
outside the orchard to be out of the way. The ‘R3’ repeater is just an alternative.
