DESCRIPTION
Product Overview
The IRRInet-M DC RTU is a remotely located unit used for monitoring and control of local
irrigation equipment. The unit can operate in stand-alone mode, or as an intelligent RTU or
node on a distributed control system. This manual describes both basic and expanded I/O
models.
The IRRInet-M DC RTU is enclosed in an indoor plastic case and is intended for indoor or
outdoor use (either wall or DIN rail mounting.) The installer must make sure that the
installation meets the requirements of the standard and protects the unit from weather hazards.
For outdoor installation, a suitable enclosure (such as UL certified NEMA box) must be
provided. The antenna must be physically secured at a permanent outdoor location.
The IRRInet-M DC RTU main power source is 9-30V DC. The IRRInet-M DC has only one
power source.
Configuration of the IRRInet-M DC RTU is performed using the ACE3600 System Tools Suite
(STS).
Figure 1 provides a general view of the IRRInet-M DC RTU.

Controls and Indicators
The push-button is used to activate the LED panel, to toggle the LED panel so that it displays
the status of the CPU or of the I/Os, to initiate software downloading to the CPU, and to erase
User Flash memory and RAM.
LED Control
Display On/Advance
When the display is off, pressing the push-button once, momentarily, activates the display.
Every consecutive momentary depression of the push-button advances the display to the next
page, in the following order: CPU > IO1 (I/O Page 1-DI) > IO2 (I/O Page 2-DO) > IO3
(I/O Page 3-DO) > Page 4 (User Application Controlled). The next depression of the push-
button returns the display to the CPU.
Display Off
The display can be programmed using the STS site configuration to turn off automatically after
a predefined period of time if the push-button has not been pressed.
LED Test
When the push-button is pressed continuously for a few seconds, all LEDs light up
simultaneously. When the push-button is released, the LEDs turn off.
User Flash Erase
After power-up, all LEDs light up. To erase the User Flash, press the push-button while the
LEDs are lit. All the LEDs flash three times. Now, release the push-button.
Alternatively, press the push-button continuously for at least 40 seconds at any time to erase
the User Flash.
System Software Downloading
During power up, press the push-button continuously. This will cause the unit to enter
bootstrap downloading mode, in which the FLASH is programmed from a PC connected to
Port 1 of the IRRInet-M. The CPU LED will begin to blink at 1 Hz, indicating that the CPU
has entered bootstrap downloading mode. If after 120 seconds no bootstrap software is loaded
and executed, the normal power-up procedure is performed.
CPU Reset (Cold Restart)/Power Off
To reset the CPU, turn the power supply to the unit off and on again. When the power supply
is turned off, all data stored in RAM will be erased ("cold restart").
CPU Fail
When a serious failure is found during the initialization of the unit, LED 3, the ERR LED, will
blink (CPU LED OFF) and LEDs in columns 3 and 4 will contain the error code indicating the
CPU error. See the list of errors below and the LEDs which will light.

Application Download
For information on downloading an application to the IRRInet-M unit, see the ACE3600 STS
User Guide.
LED Display Indications
A 5 ×4 matrix of LEDs is used for diagnostics and testing of the unit (see Figure 3). The top
row indicates to which page or toggle (CPU, IO1, IO2, IO3, Page 4, Page 5) the LED panel is
set. To advance from one page to another, press the push-button once quickly. The first
depression of the push-button activates the display. Subsequent short depressions of the push-
button advance the display to the next page: CPU > IO1 (I/O Page 1-DI) > IO2 (I/O Page 2-
DO) > IO3 (I/O Page 3-DO) > Page 4 (User Application Controlled).
Note that Page 5 (Hardware Test Controlled) can only be accessed via the Hardware Test
utility of the STS, and not by pressing the push-button.
In each page, the LEDs have different functions, as described in the charts below.
Not all LEDs are relevant in all IRRInet-M models.

The IRRInet-M DC RTU can control up to 24 DC Solenoids (twelve outputs in the basic model
and another twelve outputs in the expanded model.)
The operating voltage can vary from 4 to 35V DC (as defined in the STS site configuration.)
The IRRInet-M also responds to back indication signals from eight different field input
sensors, four inputs on the basic model and four additional inputs on the expanded model.

BOX-SPECIFIC THEORY
General
The IRRInet-M RTU includes the following main components:
• Logic board - with CPU for processing power and data storage
• I/O connections – to connect to on-site sensors, such as water meters, pressure meters,
general digital input, or outputs such as irrigation valves, pump starters, general relays, etc.
• Communication ports – enabling the RTU communication to/from the ICC, to/from other
PLC’s and to an on-site programming tool (such as the Pocket Terminal).

Box Specific Theory
16
System Architecture
In an irrigation system, the IRRInet-M unit can operate as remote irrigation device, or as
irrigation field unit that connects between the IRRInet Control Center (ICC) and the remote
irrigation devices. The unit can act as a router between the ACE3600 unit and legacy devices
(e.g. Scorpio, Impact, IRRIcom.)
The IRRInet-M is initially configured by an ICC computer. In the field, the IRRInet-M
operates and monitors the irrigation systems and periodically sends data to the ICC. Once in
the field, it can be reprogrammed using a IRRInet Pocket Terminal (e.g. to set the field unit
clock or field unit parameters) with all changes being automatically updated in the ICC.
The IRRInet-M unit can operate local I/Os or remote irrigation devices such as the Scorpio and
IMPACT remote I/O (RIO).
The IRRInet-M units (sites) in the system can communicate among themselves or with the ICC
central computers using a variety of communication, including IP networks, two-way
conventional radio, trunked radio systems, GPRS, wire line or any other communication
network.
<Significant interfaces to the rest of the system. Perspective should be from the box looking out onto the system.>
