For Technicians | AfiPass II Installation Guide
1 Introduction
AfiPass IITM is an ISO (Passive) identification system integrated into the AfiFarm herd management system. AfiPass II is based on the principle of radio frequency identification (RFID) and refers to automatic identification of animals using ISO 11874/5 compatible passive ID tags (without batteries). AfiPass II supports a per stall ID system and walk through ID systems per the configurations officially released by Afimilk. AfiPass II supports the following setups: � Parlor stall ID - per the defined models of:
Herringbone, Parallel. Note: Sort gates based on AfiPass II will be released soon. Note: Until specifically announced, AfiPass II may NOT be installed in Rotary Parlors.
1.1 Principle and Flow of Operation
The AfiPass II system communication steps are: 1. The AfiPass II Controller sends an ID request signal via an antenna. 2. The ID request signal energizes a transponder in an identification tag. 3. The identification tag responds with a unique ID number back to the antenna. 4. The antenna receives the tag transmission and relays it back to the AfiPass II Controller. 5. The AfiPass II Controller relays the tag ID number to the AfiFarm herd management system. 6. AfiFarm uses the ID number for controlling AfiFarm stations and for data collection - herd
management.

3 Ordering Components

The equipment listed here refers to the AfiPass II ID system alone, not including other products required for the full Afimilk system, communications etc. The equipment for ordering includes: � AfiPass II controllers � per parlor size. � AfiPass II antennas � per number of ID stalls and type of metal works. � Other equipment required (may be sourced separately or locally).

3.1 Ordering AfiPass II Controller System
The number of AfiPass II Controllers required is determined by the number of ID stalls in the milking parlor.
Each device supports up to 5 stall antennas. Therefore, multiple AfiPass II Controllers are required to set-up a full milking parlor. All the Controllers are connected on a single daisy chain communication line, connected at the AfiFarm PC via its communication devices (AFiCom USB).

3.2 Ordering Antenna
The AfiPass II antenna is a plastic rectangle. Each milking stall requires an individual antenna, which is mounted onto structures within the parlor (such as metal frames, or parlor walls).
For best results, the antenna should be mounted as close as possible to the cow's head, and as close as possible to the ID tag (the ear carrying the tag). However, it should also be mounted far enough from neighboring cows to avoid ID mistakes.

For Technicians | AfiPass II Installation Guide

Before ordering antenna, conduct a survey of the site to determine which antenna type best suits the parlor (see Table 2). Selecting the antenna type will also need to take into consideration optimal mounting locations (see Chapter 5.1):
Table 2 � Selecting AfiPass II Stall External Module 50 or 40

AfiPass II Stall External Module 50
The 50 cm antenna has a larger range; hence when there is enough space and the distance between the stalls is larger it should be used.
Mostly suitable for wall mounts and feeding troughs.

AfiPass II Stall External Module 40
The 40 cm antenna should be used when there is not enough space to install the 50 cm antenna.
Mostly suitable for rapid exit parlors.
The 40 cm antenna should be used when the distance between the stalls is small or lack separation, and there is a risk the larger antenna may interfere with antenna on next stall, or may read the tags on the cows in the neighboring stalls, or the cows finished milking and transferring through the exit passage.

3.3 Sourcing Antenna Brackets
The antennas are mounted in the stalls using brackets that are designed and built to suit both the antenna size and the location where it will be mounted. Custom made brackets are available for the most common parlor types. These are manufactured and sold directly from relevant companies.
Note: Custom-made brackets Antenna are available in the US market for the most common parlor types and are sold directly from relevant companies. Contact your local Afimilk representative for details.
Note: All brackets are the dealer's responsibility to source (including manufacture and purchase), according to our guidelines. For further details, contact Afimilk support.

3.4 Ordering Transformers (Requirements)

The AfiPass II system requires an isolating transformer that supplies power only to the AfiPass II Controllers. The size of this transformer depends on the number of controllers it powers.

Caution: The transformer must be supplied with suitable circuit breakers.

The AfiPass II Controller uses up to 36VA during transmission (ID request) and 19VA during idle operation.

Controllers on the same side of the parlor will never transmit simultaneously, while Controllers on opposite sides might. Therefore, we recommend installing transformers on each side of the parlor to power the Controllers on that side.

To calculate the power requirements for each transformer, use the following formula: = + ( - ); where:

� P = the transformer's required power rating in VA (Volt Amper)

� N = The number of controllers used.
For example: To power three devices a transformer with a power rating of = + = should be used.

For Technicians | AfiPass II Installation Guide
5 Mounting the Components
Mount the AfiPass II components according to the steps below.
5.1 Mounting the Antennas
Confirm the environment provides an option to mount the antenna, where the cables and antenna are protected from animals and surrounding elements (such as constant exposure to water/steam).
Note: Special consideration must be made to protecting the cables from animal licking and chewing. We recommend ducting the cables within the stall work itself. Before mounting the antenna, consider the following: � The ear (left or right) on which the tags are located. � The Stall type, size (specifically � the stall width), and structure. � The location of the cow's head within the stall, and any movement restrictions to the cow's head while in the stall. � The presence of metal loops, which substantially decrease the antenna's ID coverage. Antenna should not be mounted closer than 10 cm (in parallel) to any closed metal loops or plates in the parlor construction and metal works. Open structures (such as "U"-shaped) or perpendicular loops don't affect the range. � Existing structures within the stall (for example, feeding troughs, chest bars, neck rail, overhead bars, walls). Note: See Chapter 5 for examples of brackets on which to mount the antenna, and various mounting solutions for different parlor setups.
The antenna location and position varies according to the parlor type, metal works, Breast rail type, and position. Consequently, each mounting procedure depends on the current setup of the parlor.

For Technicians | AfiPass II Installation Guide
Positioning the Antenna
The antenna ID range can be controlled by changing the antenna orientation or adjusting the antenna transmission power. Each side of the antenna projects a different range, as illustrated in Figure 1: � A � illustrates the range projected from the front and back of the antenna. � B � illustrates the range projected from the sides of the antenna. � C � illustrates the range projected from the top and bottom of the antenna.

Figure 1 � Antenna ID Range (Side and Front Views)

Antenna range is adjustable via the AfiPass II Controller (see Chapter 8.4). Increasing the transmission power increases the ID range on each side of the antenna. In turn, this increases the distance available for the antenna to successfully detect the ID Tag. (However, it may also increase the risk of detecting incorrect tags of neighboring cows.)
Table 6 below illustrates how increasing the antenna transmission power increases the range projected on each side of the antenna. Table 6 also compares the different ranges available for the 50 cm and 40 cm antennas.

For Technicians | AfiPass II Installation Guide
Positioning the Brackets
The parlor setup affects the antenna position and brackets required for installing the antennas. The examples below provide a range of bracket design and installation locations to suit various parlor setups. Example 1: Parallel Neck Rail If installing the antenna in a parlor that utilizes a neck rail, use the 40 cm antenna. The brackets must fasten the antenna using mounting solutions that accommodate the type of neck rail and pole profile. Antenna Location The top of the antenna should sit 110 � 120 cm (43"-48") above the floor, depending on the cow's height. The top of the antenna should align 2.5 � 5 cm (1"-2") above the ear height.

Side View

Note: In vertical lift rapid exit solutions, special consideration must be given to protecting the antenna cables from bending when the rail is lifted/lowered during operation, and from contact with the cows, see APPENDIX 1 for solutions to this.
Example 2: Overhead Mounting in Parallel Parlor with Wall Mounted Feeders The example below illustrates brackets attached to a bar that runs across the top of the feeding troughs. Antenna Location The antennas are mounted as close as possible to the troughs, so that the ear tags come into range of the correct antenna while the cow eats from the trough. Bracket Attachment

For Technicians | AfiPass II Installation Guide Example 3: Herringbone (with/without Feed) without Rapid Exit In straight line parlors (with no Rapid Exit), side walls can be used for mounting the antennas in front of the cows' heads, so they are centered to the ears with the tags. The antenna type and distance depend on the height of the cows and the side of the parlor they're located on. On the parlor side where the ear tag sits further from the wall (See cows on the left side in the image at right), it may be advisable to use the 50 cm antenna to achieve a wider range. We also recommend using the 50 cm antenna in parlors without feeders and/or when there is constraining metal works below the cow's chest.

Herringbone Parlor � 40 cm antenna mounted on the wall. Example 4: Parlors with/without Feeders The images below illustrate alternative antenna location options.
Attaching the Brackets
Attaching the antennas to the brackets may require the technician to drill into the antenna plate. To avoid damaging the antenna, be very careful to only drill through the allowed section.
Warning: Drill only within the drill area as shown below.
15

For Technicians | AfiPass II Installation Guide
5.2 Mounting the AfiPass II Controller
Choose appropriate mounting locations for the AfiPass II Controllers. The locations should meet the following conditions: � Mounting stability - the AfiPass II devices require a stable structure (such as a wall or
overhead beam) on which to mount. � AfiPass II & Communication to PC - communication lines can be extended up to 350-
400 meters (383 � 437.5 yards). � Electrical interference - Place the AfiPass II Controller and the antenna cables as far as
possible from electric power lines or other electrical disturbances (especially from AC controllers, AC motors and Main power cables) to avoid electrical interference.
AfiPass II Controllers � Mounting Locations
The AfiPass II Controllers are mounted in the parlor as follows: One controller is mounted in the middle, between the two parlor sides. This will act as Device #1 (Main Display Device). Device #1 must be visible from the milking pit (to monitor the ID and gate status).
� The rest of the controllers are mounted according the number of milking stalls on each side. Device sequencing is based on sets of 5 antennas connected to each device, beginning from stall #1 which must be connected to Device #1 (Main Display Device). See mounting examples below. Note: Regardless of which side of the parlor you choose to install the Main device, when your back is to the Main device, your left-hand side should always point to the 'low' stall numbers. This will ensure the corresponding entry/exit LEDs are on the correct side of the Main Device display.
16

For Technicians | AfiPass II Installation Guide Placement of Components Example 1 Layout: Figure 3 shows the default system layout for a 2X12 Parallel parlor, where the number of stalls does not divide equally into groups of 5. The excess stalls on each side of the parlor are connected by default to a common device for both sides at the end of the parlor. This device is addressed as the last device in the parlor.
Figure 3 - Default Device Addressing of a 2X12 Parallel/HB Parlor
17

For Technicians | AfiPass II Installation Guide Example 2 Layout: In parlors where the number of stalls does not divide equally into groups of 5, and the excess number of stalls on both sides of the parlor exceeds 5 stalls, a device on each side should be installed (see Figure 4).
Figure 4 - 2X14 Parlor Layout Device Configuration (Example) Note: The parlor layout configuration can be changed manually in AfiControl to suit any required changes in the parlor.
18

For Technicians | AfiPass II Installation Guide
5.3 Mounting Process
Every AfiPass II Controller is provided with two support plates on the back, see Figure 5 below. The box can hang from the support plates. Alternatively, 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 useful in mounting the box on a beam with little overhead clearance, as the Box's cover opens upwards. The support plates protrude 6.5 cm (25/8") from the edge of the box. An M6 bolt, washer, and two nuts are used to secure the support plates to the wall or beam. To mount the AfiPass II Controller: 1. Attach the support plates to the box as shown in see below.
Caution: Mount the AfiPass II Controller on a stable, non-vibrating structure.
Figure 5 - AfiPass II Mounting Equipment 2. Bolt the AfiPass II Controller firmly to the wall or beam.

Lay the power cable from the power transformer towards the AfiPass II Controllers. 4. Lay the prewired antenna cables from the antenna towards the AfiPass II controller.
Note: You can cut the cable to size to avoid slack. Minimum cable length = 3 meters. Cable length less than 3 meters may affect optimal antenna resonance resulting in decreased ID range and a possible malfunction of the system.

For Technicians | AfiPass II Installation Guide

7 Wiring the System

Once the transformers are installed and wired to the main power supply by a certified electrician. The AfiPass II Controllers are connected and wired according to the steps below.

7.1 Grounding the System
General Instructions for Grounding:
� Verify the metal-structure is properly grounded - A qualified electrician must verify that the milking parlor's metal work and mesh are grounded according to local and international standards. This can be done either to the mains power supply (if it is in proximity to the facility), or to a grounding rod (if the mains is distant and there is a possibility of potential difference due to the distance).
� Use a short grounding wire to ground the AfiPass II - Verify that the AfiPass II devices are grounded to the milking parlor's construction with the shortest cable possible, to avoid potential loss.
Caution: Incorrect grounding can harm animals and damage the ID system.

7.2 Wiring Device #1
Device #1 acts as the Main Display Device, and the sensor cables for the entry and exit gates must be connected to this device. Device #1 must also be connected to the antennas of stalls #1 to #5.

7.3 Inserting Cables into the AfiPass II Controller
Once the cables are placed, insert them into the AfiPass II Controller. AfiPass II Controllers are provided with color-coded grommets. Insert each cable through its appropriate grommet, as described below.

For Technicians | AfiPass II Installation Guide To insert a cable into the controller: 1. Puncture the plug using a small screwdriver or any pointed object. Pull the loosened plug out
of the grommet.
Caution: Remove a plug only where a cable will replace it. If grommet holes are left open, the box will not be waterproof, and components may be damaged. 2. Unscrew the nut and remove the grommet. 3. Thread the cable through the nut, and then through the grommet hole. Allow slack for wiring inside the box, allowing the box to open and close.
4. Insert the grommet into the socket. 5. Ensure the three small slots on the grommet are aligned with the pins in the cable inlet. This
prevents the grommet from rotating when the nut is tightened. Rotate the nut one revolution on the threads, so that it is loosely held in position.
6. After inserting cables, connect the wires as described in the following section.

8 Setting AfiPass II Addresses and Calibrating Antennas
Access Test Mode to assign each device's address, and then to calibrate the antennas individually. While in test mode, adjust the required ID range (transmit power level) to ensure accurate tag detection. The above Test Mode operations are undertaken using the AfiPass II Technician Tool and SW1 DIP Switch (see APPENDIX 2 � DIP Switch). The Technician's tool contains two toggle switches (TS1 & TS2) that set the operation mode, and two push buttons (PB1 & PB2) that control the operation and set the desired parameters.
While the device is in Test Mode, communication with the PC is disabled and the COMM FAULT LED starts flashing after 30 seconds. This does not interfere with the configuration operations. The procedure's workflow is as follows: 1. Open Test Mode. 2. Assign Addresses to each device. 3. Calibrate each antenna. 4. Set the antenna's transmission power to the required ID range. 5. Exit test mode.
32

8.2 Setting Device Addresses
Each AfiPass II Controller must be set with its own address number. Note: The AfiPass II Controller Main Display Device must be set as Address 1 to display currently active antenna for the whole parlor, and the status of entry and exit gates. When configuring the Main Display Device, disconnect the gate cables. Once your activity is complete, reconnect the gate cables.
To set the device address: 1. On the Technician Tool, turn OFF TS1 and TS2. 2. On the SW1 Config. Dip Switch, turn ON SW1.3 (address switch).
Indication: The display shows 'ADR T'.
3. Click PB1 or PB2. Indication: The display shows the current address of the device 'ADR XX'.
4. Press PB1 and PB2 simultaneously. Indication: Sound is emitted for 4 seconds. The display flashes the current address of the device 'ADR XX'.
5. Change the address by pressing PB1 (increment by 1) or PB2 (decrement by 1). Note: A long press on PB1 or PB2 will increase/decrease the value by 10.
6. Press and hold PB1 and PB2 simultaneously for 3 seconds to set the address. Indication: Sound is emitted for 4 seconds. The display flashes the current address of the device 'ADR XX'.

8.3 Calibrating the Antennas
Calibrate each antenna for optimal resonance. To calibrate the antennas: 1. Set the technician's tool to CAL Mode. On the Technician toolbox:
a. Turn ON TS1. b. Turn OFF TS2. Indication: The display shows 'CAL T'.
2. Set the antenna number: Press PB1 to increase in increment by 1. Press PB2 to decrease in increments of 1. Indication: The display alternates between the antenna number and the calibration value (calibration values range from 1-127).
3. Calibrate the selected antenna: Press PB1 and PB2 simultaneously. Hold these down for 3 seconds. The calibration process takes about 30 seconds. Indication: The display shows 'CL**XX'
Indication: Once the Calibration process is complete, if successful, the display shows 'CL OK' and a sound is emitted for 4 seconds.
35

For Technicians | AfiPass II Installation Guide
The selected antenna's calibration value is now saved in the device memory and will remain unless the process is repeated and the value changes.
If unsuccessful, an error message is displayed. In this case, make sure the antenna is connected properly, the connector is in place, and no loose wires from the shield wire of the coax cable are shorted. 4. Repeat the calibration process for all the antennas.
8.4 Setting Transmission Power and Reception Range
Once the calibration process is complete, the antenna reception range may need to be adjusted to prevent ID overlaps between stalls. The AfiPass II Controller allows 17 transmission power levels, -8 to 8 with the default at 0, to increase or decrease the ID range. While in Antenna Power Mode, once the desired antenna is selected, the device will transmit continuously to enable you to set the power level for the desired ID range. The test is done using the Passive Identification tag. The RX LED and buzzer (if enabled) will indicate proper reception at the distance of the tag from the antenna. To change the transmission power: 1. Set the technician's tool to PWR Mode:
a. Turn OFF TS1. b. Turn ON TS2. Indication: The displays shows 'PWR T'.
36

For Technicians | AfiPass II Installation Guide
2. Set the antenna number: Press PB1 to increase in increment by 1. Press PB2 to decrease in increments of 1. Indication: The display alternates between the antenna number and the Tx power level (-8 to 8).
3. Enable continuous transmission: Press PB1 and PB2 simultaneously. Hold them down for 3 seconds. The selected antenna starts transmitting. Indication: Sound is emitted for 4 seconds. The display shows 'PWR 00X' as shown above (where '00X' is the current power level)
4. Hold a passive ID tag in front of the antenna in the location and distance where the ID is required and use PB1 and PB2 to adjust the Tx power level (ID range). Make sure to check the peripheral range of the ID to avoid overlaps between the stalls. Indication: The RX LED turns on and sound is emitted (if the buzzer is enabled) while the tag is within the ID range of the antenna. Note: The AfiPass II Controller has a built-in safety mechanism that limits the transmission power, so that it doesn't exceed the permitted power levels. If the power level is too high the display will show error message 'ERR 06' and the power level must be decreased.
5. Once the required range has been achieved, press and hold PB1 and PB2 simultaneously for 3 seconds to set the power level. Indication: Sound is emitted for 4 seconds and the display alternates between the antenna number and the selected power level (as shown in section 2).
6. Repeat the power level setting process for all the antennas.
37
