Afikim. The “IDeal” interfaces between the AFI system in which it is installed and the identification system’s sensors - the antennas. The main operations of this unit are: • Receiving an identification request from the computer. • Selecting the appropriate antenna to activate. • Sending power and frequency signals to activate the antenna. • Receiving the identification response from the cow tag. • Translating the analog data to a digital sequence. • Sending the identification data to the computer. In some configurations (such as in the “AFIMILK” system for Herringbone parlors) the IDeal unit sends gate status to the computer. September 14, 2003 IDeal Installation Manual 2 IDeal Installation Manual P/N 9040380 Chapter 1: IDeal Components The “IDeal” identification system consists of an IDeal box (the controller box) and antenna input to the box. The system is connected to a computer, through an AfiCom1 or AfiCom communication card, to AfiFarm herd management software. Antenna input may consist of: • One or two antennas connected directly to the IDeal box (a “2 Antenna” system). • If three or more antennas are used in the system, antennas are connected to the IDeal box by way of one or more antenna switching boxes (a “Switching box” system). Each antenna switching box may be connected to up to 16 antennas. Up to 3 switching boxes may be connected to each IDeal box. September 14, 2003 IDeal Installation Manual IDeal Controller The IDeal controller unit is a plastic box containing a printed circuit board (PCB).

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. September 14, 2003 IDeal Installation Manual 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 microcontroller 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. IDeal Installation Manual P/N 9040380 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. Settings of the IDeal Controller The next page is an illustration of the IDeal PCB, displaying jumpers, the dipswitch panel and connectors.

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. 12 IDeal Installation Manual P/N 9040380 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. When inserting the terminal block into connector J3, ensure that the ground wire connects to pin GND. Incorrect wiring may damage the PCB. 24V AC GND Warning ! J3 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. September 14, 2003 IDeal Installation Manual 13 +5 V +12 V TX_Power GND Test Points JTP1 Four test points are located at the upper right corner of the PCB, at JPT1. These test points are used for testing the power supply circuit in cases of malfunction and/or for adjustment purposes. • GND - Ground signal for all other test points. • TX_Power This is the transmission power supply level for the antennas. The level of this power determines the identification range. Therefore this voltage level is checked whenever an adjustment is required. (The power supply VTx can be adjusted by potentiometer P2). The allowed voltage range is 8VDC to 30VDC. • +12 VDC. Allowed voltage range is 11.8 VDC - 12.2 VDC. • +5 VDC supply for the micro-controller’s circuit.

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. 14 IDeal Installation Manual P/N 9040380 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. Snap lock Snap lock 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 seal. • Screws are provided in the cover, near the snap locks, to seal the box. When finished wiring the IDeal, tighten these screws to seal the box. September 14, 2003 IDeal Installation Manual 15 The Antenna Switching Box Each IDeal box can support as many as 48 antennas. In systems using more than two antennas, antenna switching boxes are required. An antenna switching box is a connection board, with a switching relay for each antenna. One box can support up to 16 antennas, and up to three boxes may be cascaded into the IDeal controller. Switching Box Board The switching box board, contains antenna connectors and serves as a buffered interface between the IDeal and antennas. 12 16 J3 PCB of Switching 11 Box Antenna signal cable 15 J2 J3 10 Antenna signal cable 14 J1 16 IDeal Installation Manual Antenna select cable 13 P/N 9040380 Switching Board Connectors The switching board contains four types of interface connectors: • Connector J1 receives the antenna select signal from the IDeal card. • Connectors J2 and J3 carry the antenna transmission and reception signals from/to the IDeal main board. Switching units are connected in parallel. The cable entering J2 may exit via J3, carrying signals to the next switching box. • Connectors 1 to 16 are the antenna connectors. Antennas must be connected to these connectors in the proper order: • In switching box #1, antenna #1 is wired to connector #1, antenna #2 is wired to connector #2, and so forth. • In switching box #2, antenna #17 is wired to connector #1, antenna #18 is wired to connector #2, and so forth. • In switching box #3, antenna #33 is wired to connector #1, antenna #34 is wired to connector #2, and so forth. • If more than one IDeal box is in the system, continue antenna connections in the same manner. (Antenna #49 is wired to connector #1 of switching box #1, of the second IDeal box.) September 14, 2003 IDeal Installation Manual 17 18 IDeal Installation Manual P/N 9040380 Chapter 2: System Configurations This chapter illustrates, in more detail, configurations of the IDeal identification system. Two configurations are illustrated on the following pages. September 14, 2003 IDeal Installation Manual 19 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.

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. Ensure that there is a very limited amount of electrical interference in the environment, especially from AC controllers (variators) and AC motors. Warning September 14, 2003 IDeal Installation Manual 23 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.

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) September 14, 2003 IDeal Installation Manual 29 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. 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. Warning 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. 30 IDeal Installation Manual P/N 9040380 Wiring Cables to Connectors Wire cables as described in this section. Connecting the Communication Cable Connect the communication cable as described below. See the AfiCom 1 or AfiCom communication card installation manual for more details on connections to the AfiCom 1 or AfiCom card. In most situations, the Current Loop communication type is used. If using C.L. connect a “P3” communication cable to Connector J4, on the left edge of the IDeal board. Connect red, green, black and white wires to the connector as illustrated below. (Ensure that jumper pins on the IDeal are properly set, as described on page 11.) AfiCom 1 Port 3, 4, 5, or 6 AfiCom1 Card (P3) to IDeal communication cable September 14, 2003 IDeal Installation Manual 31 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. (optional) 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. 32 IDeal Installation Manual P/N 9040380 Connect Antenna Select Cables (in systems with switching boxes) Connect antenna select cables as described below, and as illustrated on page 28 (On the switching box PCBs, wire colors are printed at connectors): • Connect J11 (Box select 1) in the IDeal box to J1 of Switching box No. 1. • Connect J10 (Box select 2) in the IDeal box to J1 of Switching box No. 2. • Connect J9 (Box select 3) in the IDeal box to J1 of Switching box No. 3. Connecting the Gate Switches Connect gate switches to J7 and J8 in the IDeal. These switches must supply a floating contact signal and should be connected as illustrated below, and as printed on the P.C.B. next to J7 and J8. Right Side II J7 Right Side September 14, 2003 J8 IDeal Installation Manual 33 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. 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. Warnings: When inserting the terminal block into connector J3, ensure that the ground wire connects to pin GND. Incorrect wiring may damage the PCB. 24V AC GND J3 When finished connecting wires to connectors, adjust cables to an appropriate length inside the box, then tighten grommet nuts, and close the box. 34 IDeal Installation Manual P/N 9040380 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. Indicator light 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. September 14, 2003 IDeal Installation Manual 35 The IDeal identification system has a mechanism to prevent the same cow from being identified at two stalls: Note 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. 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. 36 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, IDeal Installation Manual P/N 9040380 Note If you want to recheck the previous stall, then the IDeal signal request must be returned to the previous stall. In order to return the signal request to the previous stall, place the same tag you used to advance the signal request beside the next antenna. • 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. Left Entry Gate Position GATE POSITIONS Left Right Right Exit Entry Exit Gate Gate Gate Position Position Position Open Open Open Open The I.D. request is initiated at stall (antenna) No.1, advancing from one stall to the next, when a tag answer is received. The I.D. requests advance from stall 1 to 48, and back to stall No.1. Open Closed Open Open The same sequence as in 1, though for stalls 1-16 only. After the I.D. request arrives at stall 16, the I.D. request advances to stall 1 as a tag response is received. Open Open Open Closed The test is at stalls 17 to 32 (second switching unit), starting at stall 17, and returning to 17 after a tag reply is received at stall 32. Open Closed Open Closed The I.D. request is initiated at stalls 1 and 17 together, advancing in two separate channels (as in 2 and 3). Closed Open Open Open The I.D. request advances from stall 1 to 16, and back to 1 again without any tag response, scanning the antennas. September 14, 2003 IDeal Function IDeal Installation Manual 37 6 Open Open Closed Open Same as 5, though for stalls 17 to 32. Closed Open Closed Open Closed Closed Closed Closed Scanning stalls 1 thru 16 and 17 thru 32 simultaneously. Scanning antennas 1 thru 48 and returning to 1 again. 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. 38 IDeal Installation Manual P/N 9040380 September 14, 2003 IDeal Installation Manual 39
