* IDeal systems operate on one of two frequencies throughout the
world: HI or LOW. The part number reflects the frequency setting
of the IDeal when shipped. 4022900H designates an IDeal shipped
at a high frequency. 4022900L designates an IDeal shipped at a
low frequency. (Low frequency systems [blue antennas and tags]
are used in Western Europe. High frequency systems [orange
antennas and tags] are used in the U.S.A. and other countries.)
Cable Requirements
This section describes the cables that are needed for the installation of the IDeal system.
Communication Cable
A 4-wire shielded cable 22 AWG (0.3 mm²) carries the communication signal between
the IDeal box and the computer.
Note: The device is intended for connection to indoor
communication lines only, with maximum length 30 meters.
Power Cable
A 3-wire, 18 AWG (0.75 mm²) cable is required to supply power to the IDeal box.
Antenna Select Cables (only in systems with switching boxes)
A 7-wire, 22 AWG (0.3 mm²) cable carries antenna select signals between the IDeal
main board and antenna switching boxes. This cable also carries a 5 V DC power
supply to the antenna. Wire colors of this cable are red, white, black, brown, green,
orange, and yellow. Maximum length of this cable is 15 meters.
Tx and Rx Antenna Signal Cables (only in systems with switching boxes)
A 6-wire shielded cable 22 AWG (0.3 mm²) carries Tx and Rx antenna signals between
the IDeal box and switching boxes. This cable extends from the IDeal, cascading to the
switching units (connecting one switching unit to the next).
The drawing on page 3 depicts connections between the IDeal box and switching boxes.
Antenna Cables
Antennas are provided with cables attached. The Tx and Rx antenna signal cable,
described above, can be used to extend antenna cables.
6 IDeal Installation Manual P/N 9040380
The IDeal PCB
This section describes the printed circuit board (PCB) of the IDeal controller, and
The printed circuit board consists of three electrical circuits - a power supply circuit, a
micro-controller circuit and an RF transmission/reception unit.
The power supply circuit is fed by 24 ±2.4 VAC, supplying 5 and 12 volts for the
micro-controller circuit, as well as by Tx (Transmission) power and frequency. The Tx
power level determines the effective identification range of the system. Tx power can
be adjusted by a potentiometer on the PCB (P2). Voltages can be measured at test
points on the PCB.
The micro-controller circuit directs the digital data flowing between the antenna and the
computer. It is connected to the controller by a four-wire communication cable, and
sends data in response to the controller’s request. The micro-controller activates the
antenna that needs to transmit an identification request. It also temporarily stores some
digital data (the identification and step counter of the I.D. tag), until communication is
initiated by the computer.
The RF transmission/reception circuit is the direct connection between the micro-
controller and the antenna. It converts digital data into an analog signal sent to the
antenna and vice versa.
A few means of adjustments (DIP switches, jumpers and potentiometers), as well as some
connectors (to which cables are connected), are on the board. The drawing below displays
the PCB’s main components, connectors and means of adjustments. Verify that settings meet
requirements of the system you are installing.
September 14, 2003 IDeal Installation Manual 7
The following variables must be defined in each IDeal controller:
• Type of system:
– “2 Antenna” (only one or two antennas are connected directly to the IDeal),
– “Switch Boxes” (three or more antennas are connected
indirectly, through one two or three switching boxes. Up to 16
antennas can be connected to each switching box.)
• Frequency settings – The IDeal box can be set to operate in a
high frequency or in a low frequency. Frequency setting
depends on the location of installation. (Low frequency systems
[blue antennas and tags] are used in Western Europe. High
frequency systems [orange antennas and tags] are used in the
U.S.A. and other countries.)
• Communication type – The IDeal box supports Current Loop
communication as well as RS232 communication. C.L. is the
communication type used in Afi systems.
• Communication protocol – Digital communication is in one of
two “languages:” the “old” communication protocol, or the
“new” communication protocol (also referred to as protocol
C2000). The new protocol supports tag numbers up to 65,536.
(The old protocol is limited to a highest tag number of 4095.)
• Antenna transmission range – Antenna transmission is
determined by adjusting a potentiometer.
These settings are explained on the following pages.

Antenna reception
Warning!
Potentiometers
must be adjusted
gently. Using too
much force with the
adjusting screw
may break the
device.
Two regulation potentiometers influence working ranges
of antennas:
• P1, located near the center of the
board, is used to adjust reception
sensitivity. The IDeal’s reception
circuit is calibrated before leaving
the factory, so P1 should not be
touched. In any case, it is not
recommended to change P1
calibration without the company’s
guidance.
• P2, located on the bottom edge of
the board, determines the
antennas’ transmission voltages.
The transmission voltage
determines the antenna’s effective
working range, and should be
adjusted according to the
installation requirements. Turning
P2 counter clock-wise raises
transmission power and enhances
reception.
Note: Common Market standards allow maximum Voltage of 30 VDC
Connectors
Connectors are the interface between the IDeal controller and peripheral devices
connected to it. Below is a list of the connectors and their functions.
September 14, 2003 IDeal Installation Manual 13
J1, J2 Antenna connectors: These 7-pin connectors are located along the right edge of
the PCB. These connectors are used for direct connection of antennas to the board,
in systems where only one or two antennas are required.
Connector J1 supports antenna number 1 and J2 supports antenna number 2. When
the system is set to operate in a “Switching Box” configuration (antennas are
connected by way of switching boxes) by means of Dip switch setting, the antenna
signal to the switch boxes should be connected to the J1 connector.
J3, Power input: The IDeal system is powered by a 24 VAC from an external source (Do
NOT use the same power supply used for the milkmeters). J3 is, located at the
lower left corner of the board.
Warning !
When inserting the terminal block into connector J3, ensure that the
ground wire connects to pin GND. Incorrect wiring may damage the
PCB.
J4, Communication: Current loop communication connector. Junction J4 is the CL
connector to the AFI system’s main controller (AfiCom1 or AfiCom communication
board, in the computer). J4 is located along the left edge of the PCB.
J5, Communication: RS232 communication connector. This is an optional
communication type used only in specific situations. This connector is located
along the left edge of the PCB.
J7, J8, Gate inputs: In some configurations, the IDeal controller supports gate switch
inputs. (When a gate is closed, its respective LED glows.) These gate inputs are
connected to J7 - J8. Connectors J7 - J8 are located along the left edge of the P.C.B.
Wiring of these connectors is explained in the following chapter. Connectors J7-J8
are dry contacts (no power is supplied through these connectors).
J9, J10, J11, Antenna select: When the system is configured for a “Switching box”
system (using switching boxes), the IDeal sends an antenna select signal to the
switching boxes. The antenna select signal dictates which antenna to activate.
• Connector J11 (Box select 1) is connected to the first switching
box (supporting antennas 1 - 16).
• Connector J10 (Box select 2) is connected to the second
switching box (supporting antennas 17 - 32).
• Connector J9 (Box select 3) is connected to the third switching
box (supporting antennas 33 – 48).
These three connectors are located along the top edge of the PCB.
These connectors are active only when dipswitch SW2 is set to SW. BOX, as described
in the previous section.

A 7 segment display, and eight LED indicators are visible through the clear front cover
of the IDeal box.
IDeal Box case
The main display indicates the antenna
number currently activated (transmitting a
signal).
Two pairs of gate indicators (Left entry and
exit gates; right entry and exit gates) glow
whenever the corresponding gate is closed.
Entry and exit #1 should correspond to the
gates on the left side of the parlor. The left
side of the parlor should be the lower number
milk meters, as illustrated.
The Com fault indicator is above the Side II
gate indicators. The Com fault LED
indicates a faulty communication with the
computer, and it must be off when a milking
session is in process.
September 14, 2003 IDeal Installation Manual 15
The Tx indicator (above the Rx Data gates indicators) reflects the IDeal’s transmission
sequence. The Tx indicator blinks when identification request is sent. This indicator is
a red LED.
The Rx Data indicator reflects the IDeal’s reception status. When there is a positive
reception of an identification signal, this indicator blinks brightly. A weak flicker
indicates interference from an external source. As well, flickering or glowing of this
LED when there is no identification activity in the parlor indicates external interference.
This indicator is a green LED.
The IDeal Box
When power supply is on, the main display appears as -An internal fuse is on the
IDeal PCB. If the circuit is overloaded, the fuse temporarily opens the power circuit to
block power supply to the board. After the short circuit has been repaired, the circuit is
closed and the power supply reconnected.
Cable inlets (grommets) are on the lower side of the IDeal box. Different size cables
are inserted through grommets
of appropriate sizes. Each color
grommet represents a cable
size. This is detailed in the
following chapter.
Open the box by pressing two snap locks on the front corners.
When closing the box:
• Ensure that the cover is to the left edge of the hinges.
• Verify that the locks on the corners snap shut, to ensure a tight

This chapter illustrates, in more detail, configurations of the IDeal identification system.
Two configurations are illustrated on the following pages.
20 IDeal Installation Manual P/N 9040380
Configuration
The IDeal controller supports two working modes:
• A “2 Antenna” mode uses only one or two antennas. Switching
boxes are not required for this mode. This mode is used in
systems such as “AFIACT,” “AFISORT” and “Entrance
Identification” systems.
• A “Switching Box” mode; where three or more antennas are
connected to one or more switching boxes.
The drawing below depicts a “2 Antenna” IDeal system in a milking parlor. This
drawing depicts a basic configuration of AFIACT with walkover antennas, installed at
the parlor’s entry door.
In the drawing below, two antennas are connected directly to the IDeal.
In this situation, the IDeal is set to work in a 2 Antenna mode. (Switch No. 5 of dip
switch array SW2 is set to 2 ANT). The two antennas are connected to J1 and J2
connectors on the IDeal board.

Chapter 3: Mounting the IDeal Box
and Switching Boxes
This chapter explains the mounting of the IDeal box.
Location of the IDeal Box
Mount the IDeal box in a location that meets the following criterion:
• Mount the IDeal box on a wall or at any location from which it
can be seen from everywhere in the parlor, (or other facility
where it is used, such as a sort weigh system).
• Maximum length of the cable running between the switching
units and the IDeal is 15 meters. This means that, in some
cases, the switching units will be installed halfway through the
milking parlor, above the middle milking stall.
Note: The device is intended for connection to indoor
communication lines only, with maximum length 30 meters.
• We highly recommend installation of the IDeal close to
antennas, so that the cable between antennas and the IDeal is as
short as possible.
Warning
Ensure that there is a very limited amount of electrical
interference in the environment, especially from AC
controllers (variators) and AC motors.
24 IDeal Installation Manual P/N 9040380
Mounting the IDeal box
Each Ideal box is provided with two support plates on its back, as illustrated. The box
can hang from the support plates. Or, the support plates can be attached to the box
“upside-down”, and the plates can support the box above the point of attachment to the
wall or beam. The latter method is advantageous in mounting the box on a beam with
little overhead clearance. The support plates protrude 6.5 cm (25/8”) from the edge of
the box. A M6 bolt is used to secure the support plates to the wall or beam.
After the proper location is determined, install the IDeal box.
1. Attach the support plates to the box, in the desired
position, as illustrated below:
2. Bolt the IDeal box firmly to the wall or beam.

Chapter 5: Wiring
This chapter details wiring of the IDeal identification system.
Inserting Cables into the IDeal Box
After laying cables, insert them into the IDeal box. IDeal boxes, and antenna switching
boxes, are provided with color-coded grommets. Each cable is inserted through its
appropriate grommet.
Insert cables as described on the following page.
Green grommets – Antenna cables
6.5 mm (¼”) diameter (P/N 5001764)
Red Grommet – Communication cable
5.0 mm (3/16”) diameter (P/N 5001762)
Blue grommet – Power cable
7.0 mm (¼”) diameter (P/N 5001763)
Grommet nut (P/N 9020726)
30 IDeal Installation Manual P/N 9040380
Insert cables as follows:
1. Using a small screwdriver, or any pointed
object, puncture a hole on a side of the
desired plugs. Pull loosened plugs from
the grommet.
2. Unscrew the nut and remove grommets.
3. Insert cables through the nut, and
then insert cables through
grommet holes. Allow slack for
wiring inside the box.
4. Insert the grommet correctly into the
socket. Ensure that three small slots on
the grommet are in correct position.
This prevents the grommet from
rotating when tightening the nut.
Screw the nut one revolution on the
threads, so that it is loosely held in
position.
After inserting cables, connect wires to connectors, as described in the following
section.
Warning
Remove plugs only where a cable will replace it. If grommet holes
are left open, the box will not be waterproof, and components may
be damaged.

Connecting Antenna Cables
Each antenna is connected individually to the IDeal, or to the switching box in a
“Switching Box” system. In the IDeal box, wire colors are printed next to each
connector. In switching boxes, one pattern of color connections is printed on the board.
16 antenna connectors are in each switching box. See illustrations on pages 27 and 28.
In normal operation:
• The brown and white wires are connected together, to the
“Wht/Brn” pin.
• The blue and the black are connected together to the “Blk” pin.
• Connect antenna cables in this manner, to their respective
connectors.
Note : The "GND" Pin (labeled above “Not Used”) remains free.
Connecting Tx and Rx Antenna Signal Cables (in systems with
switching boxes)
Connect antenna signal cables as described below, and as illustrated on page 27:
• Connect J1, in the IDeal box, to J2 in switching box #1.
• Connect J3, in switching box #1 to J2 in switching box #2.
• Connect J3, in switching box #2 to J2 in switching box #3.

Connecting the Power Supply
After all other lines are connected, connect the power supply to the IDeal box. The
IDeal unit is powered by a 24 ±2.4 VAC. The power line coming from the transformer
is a three-wire cable, connected to connector J3.
Do NOT connect the IDeal to the same power supply that is used for the milk meters.
When finished connecting wires to connectors, adjust cables to an appropriate length
inside the box, then tighten grommet nuts, and close the box.
Warnings:
The ground of the main power supply must NOT be connected
to the IDeal box.
Assure that the point to which this wire is connected is a good
grounding, whether it is the metallic frame of the building, or a
special grounding electrode mounted in the ground.
When inserting the terminal block into connector J3, ensure
that the ground wire connects to pin GND. Incorrect wiring may
damage the PCB.

Chapter 6: Testing
After the installation and/or when an identification fault occurs, test for identification
range. There is more than one way to carry out this procedure, but the sequence of
actions is always the same:
• Initiate an identification request in the antenna.
• Test antenna range with a test tag.
• If necessary, adjust the Tx voltage, or replace the faulty antenna.
To initiate an identification request of an antenna, you may use an “AFI” program (i.e.
start a milking session), an “AFITEST” program, or the self-test mode of the IDeal.
Testing and Adjusting Effective Antenna Ranges
• To start the IDeal self-test mode, the fourth dip switch at SW2
must be set to TEST.
A special test tag is needed for adjusting antenna ranges.
a test tag
(high frequency P/N 4086388, low frequency P/N 4087388)
Antenna ranges can be adjusted by:
• Increasing power to all antennas, to increase ranges in all
antennas. This is done by adjusting potentiometer P2, as
described on page 11.
• Reception at individual antennas can be reduced by adding a
resistor, as described on page 39.
When in the self-test mode, the IDeal operation will be determined according to gate
switch positions. The table on page 37 describes the relationship between gate positions
and the operation of the test sequence.
Indicator light
36 IDeal Installation Manual P/N 9040380
Because of the mechanism described in the note above, two normal tags are needed to
advance the IDeal search from one stall to another. Testing of ranges is done with the
test tag. The three tags are referred to as: Tag 1, Tag 2 and Test Tag.
When adjusting effective Tx range of antennas, check the transmission field around the
antenna. Ensure that the field covers the entire area in which the cow’s tag carrying leg
may be placed, when the cow is being milked. As well, check that the field does not
overlap into the field of neighboring antennas.
Test antenna ranges as follows:
1. Set the IDeal to Test mode:
a. Turn off power to the IDeal box.
b. At dipswitch SW2 on the IDeal PCB, set the switch #4 to
TEST.
c. Turn on power to the IDeal box.
2. Open or close gates for the required test mode, according to the table on
the opposite page.
3. Test the antenna’s transmitting range.
a. Set the test tag to the non transmitting mode (both switches
OFF).
b. Place the test tag about 1 meter (3’ 3”) away from the first antenna. Slowly
move it towards the antenna until the indicator on the test tag box starts to
blink. This is the antenna’s transmitting range. Mark it on the floor.
4. Test the antenna’s receiving range.
a. Set the test tag to the transmitting mode (both switches ON).
b. Place the test tag about 1 meter (3’ 3”) away from the first antenna.
Carefully observe the antenna number and Rx LED on the main display of
the IDeal. Slowly move the test tag towards the antenna until the Rx LED
flickers and the antenna number advances to the next antenna. This
indicates that the IDeal has received the signal. This is the antenna’s
receiving range. The transmitting range should be the same as the receiving
range. The Rx LED should flicker strongly only once; if not, check for
interference in the parlor. (When there is no identification activity, check
that the Rx Data LED does not flicker or glow.)
5. Place Tag 1 beside the antenna you have just checked. This causes:
• Tag 1 to be the “identified cow” at the antenna,
• The IDeal signal request to advance to the next antenna,
Note
The IDeal identification system has a mechanism to prevent the same cow
from being identified at two stalls:
If a cow is identified by an antenna,
And then the same cow is identified in the next stall,
Then the IDeal signal request returns to the original stall where the cow
was first identified.
September 14, 2003 IDeal Installation Manual 37
• At the next antenna, the IDeal will receive the test tag signal (withot
returning to the previous antenna).
6. Repeat the mapping procedure for antenna 2 (as described in steps 3 and
4).
7. Use Tag 2 to advance the I.D. request to antenna 3.
8. Repeat the same procedure for all antennas, using Tag 1 to advance I.D.
request from odd to even stalls, and Tag 2 to advance from even to odd
stalls.
9. Return the IDeal to normal operation mode:
a. Turn off power to the IDeal box.
b. At dipswitch SW2 on the IDeal PCB, set the switch #4 to RUN.
c. Turn on power to the IDeal box.

Adding a Resistor to Reduce Transmission Range
If a reduction of transmission range is required, a resistor may be added at the connector
of each antenna. Connect resistors as follows:
1. Separate the black and the blue wires.
2. Connect the black wire to the Blk pin.
3. Connect the blue wire to the BL pin, next to the Blk pin.
4. Connect the resistor between the Blk and BL pins, as printed on the
PCB.
For a Tx range reduction a ½ Watt 10 - 400Ω resistor is used, depending on the required
amount of Tx range reduction.
Note : The "GND" Pin (labeled above “Not Used”) remains free.
Locating a Faulty Antenna
To test a specific antenna, suspected of having faulty operation, follow these steps:
1. Set the IDeal to test mode.
2. Advance the identification request to the desired antenna (using two tags - 1
& 2).
3. Test the antenna’s effective range as described in step 4 on page 36.
4. If the antenna is defective, replace it.
