1. Introduction
The DREAM 2 irrigation control system is the second generation of the well-known
DREAM family.
Additionally to the outstanding features of the DREAM system, the new generation
now offers internet communication so that users of the DREAM 2 system can access
their controllers from everywhere, anytime.
Users are offered two options for accessing the system: one known as the
CONSOLE which is a software package that has to be installed on a PC, the other is
just an internet site called the SPOT which does not need any loading and is meant
to be used on CELLULAR PHONES and TABLETS.
Both options enable the users to login to the SERVICE which is a sophisticated
software package located somewhere in the cloud acting like a mediator between
users and their controllers.
On the other end there are the controllers that also login to the SERVICE and stay
online. The SERVICE will repeatedly interrogate all the online controllers in order to
keep its DATA BASE up to date, so that users interested in some information about
their controllers, can find it in the DATA BASE.
The aim of the following manual is to describe the features of the DREAM 2
controllers and teach the users how to program it using the local MMI of the
controller.
Prior to start using the controller in any specific facility, a configuration procedure
must be executed in which the image of the controller is defined. In this manual we
assume that the configuration procedure has been fully completed either by using
the “Image Maker” of the CONSOLE or by the local MMI as explained at the
"DREAM installation guide".
For learning how to use the CONSOLE software, see the “DREAM 2 CONSOLE
guide".

1.1 The Key-board description
1.2 How to Switch-Up and Shut-Down the system
Switching up and shutting down the DREAM 2 controller are activities that deserve
some explanations:
Switching up the DREAM 2 from a switched off state is done in 2 steps:
1. Turning ON the Power Switch
2. Pushing the Start button
About the Power Switch and Start Button see the paragraph of the Power
Supply Board below.
Each time the software is restarted there will be some introductory screens
displayed, then the System manager screen (described below) will appear for a
few seconds and eventually the Main menu of the DREAM application will be
displayed. The user should wait patiently until this stage is reached.
Function keys-F1, F2,
F3, F4 (from left to right)
handle position
dependent functions.
The functions are
specified above the keys
at the Function bar of
each screen.

The internal structure of the DREAM 2 is very much like the structure of a desktop
personal computer that has an operating system which handles multiple applications
simultaneously. This kind of activity is naturally involved with opening of multiple
files as required by the active applications. As in PCs, cutting the power before
closing the open files may be a harmful action and therefore should be avoided. For
this reason we are not supposed to turn off the power switch of the controller before
the software was commanded to shut down.
The software Shutdown button is located at the Function Bar of the System
Manager screens, which can be reached from any of the DREAM 2 application
screens, by pushing simultaneously the PgDn (˅) and PgUp (˄) buttons.
Pushing the F3=Shutdown button is the only safe way for shutting down the
DREAM 2 controller. Shutting down takes time, it is necessary to wait until the lights
on the CPU board turn off. Only after the lights on the CPU went off, it is safe to
switch off the Power Switch (see below).
The Shutdown software key turns the DREAM 2 system OFF.
The Reboot software key turns the DREAM 2 system OFF and then ON
again.
The Reboot and Shutdown functions are activated by pushing the red function
keys located underneath the Function Bar of the screen. Both functions preserve all
the data included in the controller except the statuses and left quantities of
programs.

1.3 The Power Supply Board
In the following paragraphs we are going to have a look inside the box of the
DREAM-2 controller, although the information may seem to be a little technical, we
think it can be useful if the user gets familiar with the functions of the switches, the
LEDs, the fuses and some main components of his system.
When the Power Switch is off, only the yellow LED should keep on lighting,
indicating that the charging of the backup battery continues.
When the Power Switch is turned on, some more LEDs of the power supply board
will start lighting.
The red LED indicates that 24v AC arrives to the system from the transformer (in
AC systems only). If this does not happen, the power from the mains and the Main
Power Fuse have to be checked.
As mentioned above, the yellow LED indicates that the charging voltage (13.9v
DC) for the backup battery is generated. If this LED does not light, check the
Charging Fuse. The backup battery should never left to be deeply discharged, it
may harm the battery, therefore if the charging source is expected to be
disconnected for a long period, the backup battery has to be disconnected as well,
otherwise when the charging is restarted, the deeply discharged battery may draw a
high charging current that may blow the Charging Fuse (F3).
The green LED indicates that the 12v DC arrives into the system. The 12v DC is
used for feeding all the electronic boards of the system; it may be generated either
Power Supply Board

from the charging device or from the backup battery, when the charging device is
off. In case of AC systems the charging device is the transformer, while in DC
systems it is the solar panel. The system is protected from excess current
consumption from the 12v DC source, by the 12v DC Fuse (F2).
Important remark: The charging current passes through both the Charging
Fuse and the 12v DC Fuse, so if for some reason the 12v DC fuse is blown there
will be no battery charging, although the charging voltage exists (yellow LED ON).
The red LED of the USB will start lighting only after the Start Button is pushed,
indicating that the system is now up and running. Together with the USB LED of the
power supply board, the red LED on the Mother Board and the three red power
LEDs on the CPU Board ███will start lighting as well.
1.4 The CPU board
Looking underneath the front panel, at the back of the LCD display we are going to
find the CPU Board which is the brain behind all the activities of the controller. Let’s
get familiar with some of the components on the CPU board:
CPU board
Cellular modem
The CPU chip
Lithium battery
Ethernet card
Buzzer
Reset button
LCD contrast
adjustment
The power ON
indication LEDs
Remote I/O
communication

When the DREAM 2 application starts running, a few activities start in parallel:
The LCD display connected to the CPU board will start showing some
introductory screens until arriving to the Main Menu.
The CPU starts scanning all the Interfaces second by second, sending them
the required status of the outputs receiving back the status of the inputs.
This activity is indicated by blinking of the REMOTE I/O communication
LEDs on the CPU Board and on each of the Interfaces.
Right after starting up the DREAM 2 application, the controller starts looking
for its host server on the Internet, in order to login to the service.
1.5 The concept of the internet communication
The DREAM 2 has 3 options for accessing the internet:
Using a Cellular Modem supplied by Talgil and plugged into the CPU board.
Using an Ethernet card for connecting to a Local Area Network.
Using a USB Netstick plugged into the motherboard.
The controllers after power up use their internet link to login to the service and stay
online.
As mentioned above, users have two options for accessing the system: one option is
the software package called CONSOLE and the other is the internet site called
SPOT.
Both options enable the users to login to the SERVICE which will coordinate
between users and their controllers. Additionally the SERVICE contains a large
DATA BASE that stores all the information about all the controllers and the
ADMINISTRATION software that decides about who is permitted to access which
controller.
The Server will interrogate all the online controllers repeatedly in order to keep the
DATA BASE up to date, so that users interested in some information about some
controllers, can find it in the DATA BASE.

The drawing below demonstrates the physical layout of the communication between
users and targets (controllers) in the DREAM 2 system.
For setting up the internet communication there are some parameters to be defined.
The setting of these parameters is the job of the technical person in charge of the
system installation. Those who are interested can find information in the chapter
dealing with the SYSTEM MANAGER screens in the Installation Manual of the
DREAM 2.
