In this picture you see the interface board that we can use to make changes to the system while out in the field.  This can include manual operation of the stations and we can make other system changes to the clock through this interface.  We do not use this option very often in the field, we tend to make all changes in the central computer.  There are a few key pieces to making sure we maintain a healthy landscape and these clocks are easily one of the most important pieces of equipment we have.

With any system, redundancy is always the safest way to operate a crucial system.  In the case that one part fails, there are ways to continue operating and not have catastrophic failure of the entire system.  One of those benefits is that we can actually use the field interface to create programs and run the irrigation system without the need for the central computer in the case of a computer failure.  Also in the case that we have radio communication problems, the clocks will continue to operate on the last known command for up to 2 weeks without new input.

As the irrigation companies have grown they have continued to help Turfgrass Managers sleep at night! Which I can say is a great thing.
