2.1 THE TWIG ADVANTAGES AND FEATURES:

TD200 CONTROLLER FEATURES:

The following discussion refers to the basic wireless network in this gure.

The TD200 uses simple programming steps to create a coordinated irrigation schedule for up to 100

TWIGs. It is the backbone of the wireless network. Programs are loaded into the TD200 controller

through the simple press of buttons.

The programming menus in the TD200 are used to set up the irrigation schedule for each valve. The

program is based within the controller. The TWIG valve modules do not have the irrigation schedule

but simply operate the valves as instructed by the controller. The TD200 also has a USB port so a

USB stick can retain programs and log irrigation events.

The TD200 programming easily create groups of one or more TWIG valves. The groups can operate

one time or multiple times or even continuously repeating. A schedule can be set to wait for a future

time to start a program.

TWIG FEATURES:

There are three models of TWIGs for the various eld irrigation applications:

 TWIG-1 is to control a single valve to open and close in a sequence such as

frequent irrigation of a solid set sprinkler or drip system.

 TWIG-2 controls two valves to open and close in a sequence. It is useful for

dual irrigation systems in the same orchard such as sprinkler over-tree and

under-tree or a sprinkler and drip system combination.

 TWIG-4 controls up to four valves to open and close in a sequence. One benet

is the number of TWIGs in the eld are reduced.

In addition to these standard models, external TWIGs can be special ordered for some special

applications where an external antenna is needed. They require Omni antennas.

The TWIG is powered by 2 D-cell batteries located inside the weatherproof enclosure. The batteries

power the radio and the latching solenoids. The solenoids provide the on/off control of valves.
