(PIU) and Piccolo–XR units. The Distributed I/O System
includes PIUs and Piccolo–XRs. Each PIU can be linked to up

General Description
The Distributed I/O System (DIOS) is a self-sustained system
designed to function within the IRRInet irrigation control
product line.
The DIOS consists of the following components:

Piccolo Interface Unit (PIU)

Piccolo–XR Units
The PIU functions as an interface between the host application
(irrigation SW and HW) and the Piccolo–XR units. The PIU
and Piccolo-XR are portable devices, which are used in fixed
installations. The PIU uses one of its communication ports to
link to the host application and radio communication to link to
the Piccolo–XR units. Figure 1 provides a general view of the
DIOS System.
