Why a strong signal is important: A weak signal will work harder thus taking more battery power.
Precise timing and good signal strength helps a lot so stay within range. Batteries are an essential
part of the TWIG system and great care has been taken for effective power management. Waking
and sleeping each radio when they are not working is a good way to retain the battery charge but
knowing when to sleep and wake up again is the key. The radios will not sleep until the message
return has been completed. Until a reply from the eld TWIG conrms back to the controller, the
“retry” stays working. So the sleep time advantage can be used to extend battery life. Strong signals
result in longer batter life and in a reliable system.
Communication between the TD200 controller and each TWIG:
The simplest route of the radio signal is direct. Keep in mind that radio can project is all directions at
once so very complex signal routes can be developed. It is best to set up the network in the eld so
that each TWIG talks directly back and forth to the controller. Repeaters can be used if necessary.
THE CONTROLLER ANTENNA IS STRONGER THAN THE TWIG ANTENNA. LOCATE
THE TWIGS CAREFULLY!
Determine range between controller and TWIG valves:
It is essential for owners to know the maximum range for the system. The distance presented in the
guide are only achievable under optimum installation conditions. The environment is the variable
which must be considered in all aspects of the radio system.
Basic range factors:
Radio signals have issues penetrating water and soil. These are in abundance in the eld. When
radio waves hit an obstacle like the soil some of the power is reected and some of it is absorbed
into the ground. In either case the signal is weakened. To overcome this issue two antennas have
been designed within the TWIG box. The TWIG has built in a signal logic to immediately switch to
the antenna having the stronger of the two signals. Still it is necessary to adjust the range graphs if
the radios are on the ground.
There typically is a lot of water in crops which will absorb the signal. The graph below is used to
show the limits of spacing between the units in the eld. To build these graphs radios have been
compared at several heights. The height of about 18 inches above the ground was selected for the
TWIG as a typical height. But predicting variables in the crop and environment are impossible.
