INTRODUCTION

Scope of this Manual

This manual provides instructions for the installation and
operation of the Distributed I/O system Piccolo Interface
Unit (PIU) and Piccolo–XR units. The Distributed I/O
System includes PIUs and Piccolo–XRs. Each PIU can be
linked to up to 256 Piccolo–XRs. For more information on
the PIU and Piccolo–XR, see the online help of the DIOS
Service Toolkit.

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 commonly 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.

I/O's

The battery-operated Piccolo–XR unit is available in
various models with different options of Inputs and
Outputs. The Piccolo–XR unit can operate DC latch
solenoids (outputs), read status and calculate flow of dry
contact meters (inputs).

The units are equipped with built-in radio for
communication with the PIU.

The DIOS automatically builds communication network,
using Store and Forward (S&F) technology, enabling the
DIOS to cover areas larger than normally possible when
using a single radio to communicate with the PIU.

Using the DIOS, the IRRInet system opens and closes
stations (manually or automatically by irrigation
programs), reads dry contact input status, calculates flow
rate and accumulates pulses from water meters.

Introduction

PIU - Piccolo Interface Unit

The Piccolo Interface Unit (PIU; see Figure 2) is connected
to the IRRInet Field Unit (FU) via RS232
or RS485 serial ports.

Each PIU supports up to 256 Piccolo–XR units, with any
available I/O combination, limited by the capacity of the
IRRInet software only.

Utilizing the S&F technology and networking capabilities,
the PIU can be linked to Piccolo–XR units positioned in
distances of up to 1500-2000 meters (approx. 1 mile),
depending on topography, antenna type and antenna
installation.

The PIU is an interface between the Piccolo–XR and the
IRRInet FU, which provides communication and
networking operations only. (Monitor and control features
are not included in the PIU.) That is: The control and
monitor functions are provided either locally, by the
Piccolo–XR or by an upper hierarchy unit (i.e. IRRInet
FU).

The PIU is a portable device, which is most commonly
used in the fixed installations enclosed with an indoor
plastic housing.

The PIU must be installed by qualified and authorized
technicians, so as to meet applicable safety standards and
to ensure protection against weather hazards for the unit.

If the PIU will be connected to outdoor lines, an interface
unit, complying with Clause 6 of the UL 60950 standard
must be provided.

Introduction

Figure 2
PIU – General View

Piccolo–XR

The Piccolo–XR is an intelligent, microprocessor based
unit that can be used to monitor and control local units in a
multi unit communication network. Piccolo–XR units
communicate data to a PIU while functioning as intelligent
nodes in Distributed I/O monitor and control systems. The
Piccolo–XR is often used in irrigation and water
distribution systems (i.e. irrigation valves, water meters,
fertilizing meters, various sensors, flushing filters, and
other non-irrigation devices).

The Piccolo–XR is ideal for use in applications where very
low power consumption is essential. The Piccolo–XR is
also available in an outdoor resistant housing (IP66),
designed to resist harsh environment, such as exposure to
sun, dust, and pouring rains.

RF Energy Exposure Booklet for PIU and Piccolo XR
Units, Motorola publication no. 6802974C70, which is
distributed with the devices.

INSTALLATION

General

SAFETY SUMMARY

The PIU and Piccolo–XR must be installed by
qualified and authorized technicians, specifically
qualified to handle high voltage if the installation
involves high-voltage connections/installations.

If the PIU will be installed outdoors, an outdoor
plastic housing complying with UL60950 standard
clause 6 is required.

Note!

Note!

See Piccolo–XR Screw Mounting Options (pg 19)
for mounting details.

This equipment is tested with specified length
cables and in standard enclosure. If longer
cables or a different enclosure are used, the
installer is responsible to ensure that the
installation complies with the requirements of the
applicable standards.

The PIU is enclosed in a plastic housing, allowing 3 mounting
options:

• Wall mount (Screws)

• Bracket mount

• DIN rail mount

Installation

Before installing the PIU, verify that there is sufficient space
around the unit according to the specific installation.

Mounting the PIU On A Wall Using Screws

Secure two screws (not supplied) of maximum 0.37” (9.5 mm)
head size to the wall, 3.256” (82.7 mm) apart. The wall­mounting template in Appendix D can be used to determine the
space between both screws.

The screws must not protrude from the wall surface by more
than 0.23” (6 mm) or by less than 0.16” (4 mm).

Attach the unit to the wall, fitting the two shaped cavities on
the back cover of the unit over the screws and sliding it down.
(See Figure 5.)

Mounting the PIU Using a Bracket

Using four M3x6 or M3x8 screws, attach a bracket (not
supplied) to the back of the PIU. The upper two bracket holes
must be 81 mm (3.19”) apart, and the lower two bracket holes
must be 61 mm (2.40”) apart and 54 mm (2.13”) below the
upper holes, as shown in Figure 6.

Attach the bracket to the mounting surface.

NOTE!

Verify that all power connections are made in
accordance with the applicable local standards.

PIU Ground Connections

Use the FKN8254A cable to connect the grounding cable
directly to the TB connector of the PIU as shown in Figure 9.

The grounding connector is also used as an

NOTE!

ON/OFF switch, and the unit cannot be powered on
without connecting it.

Installation

Power Connection

The PIU can be powered by various types of supply sources:

• Internal (9VDC) battery;

• External 6V or 12V DC battery;

• Motorola power supplies – controllers. For example:

IRRInet XL, IRRInet XM, IRRIcom, MOSCAD;

• 24VAC.

NOTE!

9VDC Internal Battery

The unit DC voltage range is 6 to 16 volts.

Incorrect replacement of the battery can result in
explosion! Replace only with the same or with an
equivalent type of battery recommended by the
manufacturer.

Dispose of used batteries according to the battery
manufacturer instructions.

Place a standard 9VDC alkaline battery (not supplied) into the
PIU battery chamber (see Figure10). Battery operation is
applicable when operating the unit in a non-radio mode, e.g.
when the PIU is used as an adapter.

Installation

Installation of an Internal Battrey

Release the screw at the top of the battery chamber door, and
slide the door out, as shown in Figure 10.

Connect the 9V battery cable (FKN8204A) to the DC power
input connector on the back of the unit.

Connect the 9V DC battery to the cable.

Place the 9V DC alkaline battery in the chamber as shown in
Figure 10.
