Technical Manual AM Systems Introduction v4.4 Page 6 of 72 2 Introduction The products mentioned in this manual are Electronic Article Surveillance (EAS) systems based on Acoustic Magnetic (AM) technology operating at 58 kHz. They are manufactured by Cross Point B.V. Waanderweg 12 7812 HZ Emmen The Netherlands +31 (0)591 668866 www.crosspoint.nl 2.1 Available AM systems This technical manual applies to the following AM systems: x MAXUS AM50 Mono x MAXUS AM50 Receiver x MAXUS AM50 Mono Advertising x MAXUS AM50 Receiver Advertising x STYLUS AM30 Mono x STYLUS AM30 Receiver x FORTUS AM40 Mono x FORTUS AM40 Receiver x NEXUS AM30 Mono x NEXUS AM30 Receiver x MODUS AM30 Mono x MODUS AM30 Receiver All examples in this manual are based on the NEXUS AM30 Mono and NEXUS AM30 Receiver with integrated visitor counters. For antenna models without integrated visitor counters, various shown features will not be applicable. See section 2.4 for further model-based restrictions. 2.2 Field Bus Network structure Both transceiver and receiver are interconnected through CAT5 wiring and can be connected to a host (e.g. a CrossCONNECT Access Point or a computer) and communicate with this host using the Cross Point Field Bus Protocol. This allows retrieval of device information and various settings to be made through use of the software. All this functionality is described further on in this manual. 2.3 Visitor counting Visitor counting for an aisle is possible when bi-directional IR-based visitor counter modules are integrated in the transceiver and receiver antennas. In a three antenna system two aisles can be defined because the visitor counter receiver and transmitter work in both directions. The capabilities of an EAS system with visitor counter modules are much richer than a system without visitor counter modules. Partly this extra functionality can be used by using the AM systems as an autonomous system, but most extra functionality can be added by connecting it to a CrossCONNECT Access Point.
Technical Manual AM Systems Introduction v4.4 Page 7 of 72 Some of the extra functionality is listed below. x Automatic antenna arrangement x Possibility to count customers per aisle and to determine the direction of movement (in or out of the shop) x Showing the importance of the alarm (is a customer moving in or out during the alarm) x Detecting undefined alarms x Pinpoint the exact aisle where the alarm occurred x Generate reports on visitor counts and alarm counts x Doorbell function for incoming and/or outgoing customers
Technical Manual AM Systems Introduction v4.4 Page 8 of 72 2.4 Restrictions and limitations The following restrictions and limitations must be considered: 2.4.1 AM systems versus RF systems It is not allowed to connect AM systems together with RF systems to the same Field Bus! Pins 3 and 6 on BUS A and BUS B of the AM transceiver and receiver boards are not interconnected. They are used for communication between the AM transceiver and the AM receiver. On RF systems, pins 3 and 6 are used for synchronization purposes between the RF transmitter and the RF receiver, which is based on a completely different signal. Connecting AM and RF systems to the same Field Bus will result in bad performance and synchronization and must be avoided! 2.4.2 Model restrictions The model restrictions are listed below: Lights only The lights only model does not contain any visitor counters, but does contain LED indicators, which results in the following limitations: x No visitor counting, doorbell or auto antenna arrangement x No distinction between incoming and outgoing alarms If all of the above mentioned features are required then the model with integrated visitor counters must be used. This manual covers the complete functionality of the NEXUS AM30. Keeping the above mentioned model restrictions in mind, sections related to visitor counting and/or alarm indication must be ignored when models without integrated visitor counters are used. 2.4.3 Software restrictions The AM systems can be tuned with Cross Point’s Device Explorer software. During first-time setup of Device Explorer you are required to specify your Cross Point Cloud credentials in order to be able to use the Device Explorer software. If you do not have an account yet then contact your company’s administrator or Cross Point to obtain one. 2.4.4 Detection distances The specified detection distances are maximum values. Dependent of environmental noise, these maximum values might not be achieved and aisle widths need to be reduced to obtain good system performance. See chapter 3 for more details on potential noise sources and installation guidelines.
Technical Manual AM Systems General AM and EAS issues v4.4 Page 9 of 72 3 General AM and EAS issues This chapter covers the various issues related to Acoustic Magnetic systems and Electronic Article Surveillance systems in general, like: x Noise sources x Installation guidelines 3.1 Noise sources Listed below are various noise sources that might affect the performance of any EAS system. It is strongly advised to either eliminate these noise sources (as far as possible) or maintain the largest possible distance to these noise sources. The following devices can create or absorb AM noise signals which can reduce the performance of an EAS system: x AM systems installed in other shops (even if they are installed up to 100m or more away from your store). x Any electronic device that operates around 58kHz or produces harmonic frequencies around 58kHz. x An active laptop. The back light in the screen can create a lot of noise which is detected by the EAS system and can reduce the performance dramatically. Make sure to keep laptop computers at least 3 meters away from the antennas. x (Moving) Objects containing metal, like sliding and revolving doors, elevators, escalators, roller shutters, frames, etc. x Electronic devices, like computers, laptop screens, LCD screens, cash registers, engines, transformers, etc. x Vertically positioned power cables, both low voltage and high voltage. x Lights (flashing, fluorescent, halogen, gas-de-charge, etc.) x Metal scan systems installed in close vicinity. Cross Point’s Metal Scan operates around 19kHz in channel 0 and has a second harmonic frequency around 58kHz. 3.2 Installation guidelines Listed below are EAS installation guidelines to ensure a proper installed and functioning system. Not following these guidelines might result in less performance of the EAS system. 1. Check the shop entrance/exit carefully for possible noise sources prior to installation. If possible noise sources are found then try to eliminate these sources or pick the best position for the EAS system where the influence of these noise sources will be minimized. 2. If possible, connect a TRX or a set of antennas (1 TRX and 1 RX) and put them in the required position in the entrance/exit without drilling holes in the floor and bolting the antennas down. Switch the system on and test the performance. In this way the noise level and system sensitivity can be determined and if necessary (in case of high noise or poor sensitivity) the system can be moved to find a better position. 3. Always install the TRX antenna on that side where the highest noise is or where the highest noise can be expected.
Technical Manual AM Systems General AM and EAS issues v4.4 Page 10 of 72 4. Install the power supply for the EAS system at least 1m away from the antennas. If the power supply needs to be installed further away from the system make sure to extend the secondary power cable using a proper cable with the same dimensions (3 x 1mm2) and specifications as the original cable (preferably the exact same cable). Extending the power cable with a cable with different dimensions and specifications might result in less performance of the AM system. 5. Avoid unnecessary long cables. Run the power supply cables in a direct line to the EAS antennas. Never run power supply cables vertically up the wall within one meter distance of the antennas (never around the entrance/exit doorframe). 6. By default the shielding of shielded cables is not connected to the electronic boards or antenna frames if not stated otherwise in the Connections chapter of this manual. Only in case of high noise and bad performance it is advised to experiment with connecting the shielding to see if these connections will improve the performance. 7. Do not connect more than 1 transceiver antenna to 1 power supply. 8. Metal framed doors may never swing between the EAS antennas, as this will distort the energy field of the system in such a way that it might result in high noise, poor detection and potential false alarms. 9. Do not connect unshielded and untwisted cables to the I/O’s as this might affect the performance of the EAS system in a negative way. 10. Do not attach any equipment or devices to the antenna frames. 11. Take into account that when using a laptop within two meters of the antennas, the laptop or its power supply might create noise signals. Use a longer cable to create more distance between the laptop and the EAS system. 12. Use chemical anchors to mount the antennas firmly to the floor. Do not use screws and plastic plugs, as this usually results in the antennas getting loose and instable. 13. Do not install TRX and RX antennas with less than 50cm distance between them as this will have a negative effect on the performance. 14. Where possible, use conduits to run the cables through. Make sure to use conduits with a large enough diameter. In some situations you might need to run 3 cables through the conduit. The power supply cable is ø8mm and the average FTP cable is ø6mm. When for example 2 power supply cables and 1 FTP cable need to be run through one conduit, then this conduit must have a diameter of at least 25mm. 15. A cable tester is required. The various devices are interconnected through FTP cables. Make sure to test the cables prior to plugging them into the RJ-45 connectors on the devices, especially if you’re not using pre-assembled cables! 16. It is recommended to use steel anchors (e.g. SPIT EPOMAX resin with zinc coated steel rods) to mount the antenna to the floor. Do not use screws and plugs, as this will not keep the antenna properly fixated to the floor, resulting in tilting antennas and potential loss of performance.
Technical Manual AM Systems Equipment and tools v4.4 Page 11 of 72 4 Equipment and tools The following equipment and tools are advised to use when installing and tuning the AM system. 4.1 General installation tools The general tools required for installation of an EAS system (drills, screwdrivers, cutters, etc.) are not described in detail. 4.2 Laptop computer To properly adjust the AM system through Cross Point’s software, it is strongly recommended to use a laptop computer. A laptop will put you in full control of all AM system settings and features. The following minimal requirements are set for the laptop: x Intel 1.3GHz or faster processor x Microsoft Windows Vista with Service Pack 2 (32 bit and 64 bit) x Microsoft Windows 7 or 8 with Service Pack 1 (32 bit and 64 bit) x Microsoft .NET Framework 3.5 Service Pack 1 x 512MB of RAM (1024MB recommended) x 50MB of available hard-disk space for Device Explorer x Minimal screen resolution 1024x768 (recommended 1600x1200) x Video hardware acceleration 4.3 Software The various transceivers and receivers are interconnected through the Cross Point Field Bus (see chapter 6.3, page 17 for further details on the Field bus structure). To be able to adjust and configure the various devices, Cross Point Device Explorer is required. Please refer to the Cross Point Device Explorer User Manual for further details on all features and usage of this software.
Technical Manual AM Systems AM operating principle v4.4 Page 12 of 72 5 AM operating principle The AM system operates on the pulse-listening principle. Using the zero crossing of the 50Hz mains frequency as a trigger, a short burst of 58kHz signal is transmitted and a receiver window is ‘opened’ after the transmission burst has stopped. If a tag was present within detection range during the transmission burst, the resonance of this tag will be detected in the receiver window and an alarm will be triggered. A single 50Hz mains frequency cycle is dived into three phases; phase A, B and C. Each phase covers 1/3 of the 50Hz cycle duration. A noise reference window is opened to detect the environmental noise. This signal is compared with the signal received in the receiver window and allows the software to properly distinguish a tag signal from a noise signal. Figure 1 shows the AM operating principle (at 50Hz, with a default delay of 200μs) during one 50Hz cycle. Figure 1: AM operating principle Transmission burst Receiver window Reference window Phase C Phase B Phase A
Technical Manual AM Systems AM operating principle v4.4 Page 13 of 72 5.1 Synchronization principle When multiple AM systems are installed in each other’s vicinity, it’s very important to properly synchronize the transmission burst and receiver windows for all systems involved. If systems are not properly synchronized they will create false alarms and poor detection! Keep in mind that AM signals, when compared to other EAS technologies, can “travel” quite far (up to 100m or more) because of their longer wavelength. Figure 2 shows two AM systems that are not properly synchronized. Figure 2: Two AM systems NOT synchronized The transmission burst of system B starts later than the burst of system A, resulting in the fact that system A is receiving the transmission burst of system B in its receiver window. This might create false alarms and poor detection on system A, where system B will function properly as the transmission burst of system A is not affecting the receiver window of system B. This problem can be solved by making sure that both systems transmit and receive at the same moment, which can be realized by changing the delay time for one of the two systems. Example: System A has currently a delay time of 0.2ms and system B a delay time of 1.4ms. The delay time of system B needs to be corrected to the delay time of system A (or vice versa), so their mutual transmission burst and detection windows will overlap each other (see Figure 3). This will result in both systems working properly without interference (see Figure 4).

Technical Manual AM Systems Connections v4.4 Page 15 of 72 6 Connections In the following chapters the connections between the TRX board, RX board and Controller are described. Furthermore the Printed Circuit Boards (PCB) and the manual adjustments are explained. 6.1 “A” and “B” side of the antenna The antenna has a front side (A) and a back side (B). These sides are indicated on the visitor counter in the top/middle of the antenna. The A-side is the side on which the electronic boards can be accessed. When using the visitor counter (see also chapter 6.12 (page 34)) try to put all antenna’s in the AB-AB pattern, i.e. all antennas should be placed in the same way. Figure 5: Antenna AB-AB pattern Side B Side B Side A Side A RX1 RX2 TRX1
Technical Manual AM Systems Connections v4.4 Page 16 of 72 6.2 How to access the electronic boards In order to be able to access the electronic board, the top of the antenna needs to be removed as well as the Plexiglas plate(s) and the metal front cover. Follow the next procedure carefully to do this. 1. Put your left hand on top of the top part 2. Put your right hand around the antenna frame on the right side of the antenna 3. While pushing the top part to the right with your left hand (1), push the top part up upwards with the thumb of your right hand (2). This will unlock the magnets and the ‘click’ locking mechanism and the top part can be removed 4. Slide the Plexiglas plate on side A of the antenna upwards. Out of safety reasons is it strongly advised to remove this Plexiglas plate completely when servicing the electronics. When this is not possible make sure the Plexiglas plate is supported properly after it is moved upwards, to prevent it from falling down and causing an injury. 5. Unlock the screws in the front cover (side A) 6. Remove the front cover 1 2
Technical Manual AM Systems Connections v4.4 Page 17 of 72 6.3 Field Bus connections The TRX and RX antennas are interconnected through the Field Bus by using preferably FTP cables, because FTP has an advantage to eliminate noise because of the extra shielding. The Cross Point Field Bus requires the devices to be connected in a “daisy chain” connection. A “star” network is not allowed and will result in poor communication between the devices and the host computer or controller! Each device (TRX PCB and RX PCB) has a unique address. This address is factory set and cannot be changed. A PC/laptop enables local maintenance of the TRX and RX boards by using the Device Explorer software. When the Field Bus is connected to the Access Point and the Access Point is connected to a Local Area Network (LAN), local servicing and data retrieval is possible. When an Internet connection is available, the Access Point can also be connected to the Internet, which enables service and data retrieval from any remote location over the Internet. 6.3.1 Bus connections with laptop Figure 6 shows the Field Bus structure between the various antennas. Connecting the Field Bus to a laptop (through an Access Point), allows on-site maintenance through the Device Explorer software. See chapter 0 for further information on how to use the Device Explorer software.

Technical Manual AM Systems Connections v4.4 Page 18 of 72 6.4 Field Bus termination For the Field Bus to operate properly the bus needs to be terminated on the first device and the last device in the bus. When an antenna is either the first or the last device in the Field Bus, then the bus needs to be terminated on that device. In the example in Figure 7 the bus needs to be terminated on the Access Point (which is automatically done by the Access Point itself) and on RX2. Figure 7: Field Bus termination example 6.4.1 TRX bus termination Switch TERM to ON to terminate the bus on the TRX. 6.4.2 RX bus termination Switch TERM (SW1) to ON to terminate the bus on the RX.

Technical Manual AM Systems Connections v4.4 Page 31 of 72 6.10.3 I/O connections The AM TRX board is equipped with two I/O’s which can be used for connecting a pushbutton (Forced Alarm option) or as output for other external devices (e.g. camera). To avoid interference, caused by the wires which will be connected to any of the I/O’s, it is very important to only connect the wires to the I/O connector contacts. Do not connect any of the wires directly to a GND contact on the TRX board or on the power supply! Use the “GND” connector to connect to the ground. The I/Os have a current limit of 70mA. Do not connect devices to the I/Os that draw more than 70mA, else the I/O drivers will get damaged! Figure 16 shows the proper way to connect a “Forced Alarm” pushbutton between “I/O1” and “+”.

For this reason it is not allowed to connect RF and AM systems on the same Field Bus!
Technical Manual AM Systems Connections v4.4 Page 34 of 72 6.12 The visitor counter The AM models can be equipped with a visitor counter. This counter allows counting of visitors as well as determining the movement direction of a person who generated an alarm. Both TRX and RX antennas can therefore be equipped with a visitor counter PCB. The TRX antenna holds the RX visitor counter PCB (IR-RX) and the RX antenna holds the TX visitor counter PCB (IR-TX). Figure 18 shows the visitor counter principle. Figure 18: Top view of the visitor counter principle The IR LED on side B of the RX antenna transmits an infra-red signal, which is received by both IR receivers on side A of the TRX. When the infra-red signal is interrupted by a person walking in (incoming), first IR-RX1 will receive no signal and then IR-RX2 will receive no signal. In this way the visitor counter registers the movement direction. The same principle is used for outgoing persons. As shown in the above figure, each visitor counter PCB has an A and B side. The transmitter IR-LED’s and the IR receivers can be switched on or off per side. This is necessary for each first and last antenna in a row. For example, if the system in the above figure consists just of two antennas, then the visitor counter side B of the transceiver antenna and side A of the receiver antenna must be switched off. The Device Explorer software will automatically activate the visitor counters dependent of the antenna lay-out. It is possible to increase the intensity of the IR-LED’s. This can be useful in bright and sunny environments, to ensure proper functioning of the visitor counter. For the visitor counter to operate properly the minimum distance between the transceiver and receiver is 0.5m. The maximum distance is 3m (per aisle). visitor counter PCB (IR-TX) visitor counter PCB (IR-RX) IR LED’s IR Receivers Side B Side B Side A Side A Incoming IR-RX1 IR-RX2 Outgoing
Technical Manual AM Systems Connections v4.4 Page 35 of 72 6.13 Various connections For proper operation of the AM system, it is very important to interconnect the transceivers and receivers in the correct way. This chapter shows and explains these various connections. 6.13.1 Single antenna system (no aisle) The AM system can be used as a single antenna system (mono). When no receivers are connected to the transceiver, the transceiver will automatically function as a mono antenna system. Visitor counting is not possible. Figure 19: Single antenna system Multiple transceivers 6.13.1.1In case only transceivers are used, the transceivers can either be used as complete stand-alone antennas, or they can be interconnected with FTP cables to create the Field Bus. Connecting the Field Bus to a computer or controller will allow central (remote) maintenance and reports to be generated. Visitor counting is not possible. Figure 20: Transceivers only with FTP connection PSU TRX1 TRX1 TRX2 FTP PSU PSU
Technical Manual AM Systems Connections v4.4 Page 36 of 72 6.13.2 Dual antenna system (single aisle) In case receivers are connected to the transceiver it is of great importance to connect the FTP and analogue connection cables to the proper connectors on the TRX and RX boards. Figure 21 shows the connections for a dual system (TRX + RX). Figure 21: Dual antenna system connections Backfield control 6.13.2.1When only one receiver antenna is connected to a transceiver and this receiver is connected to Bus A of the transceiver, then the detection of the B-side of the transceiver can be reduced if required. This is called ‘Back field control’. When enabled, back field control makes it possible to reduce the back field detection of the TRX antenna by switching of its internal receiver circuit. The TRX antenna will then act as a transmitter only and detection is on the RX antenna only, resulting in a concentrated detection area between the antennas. Backfield control is only possible on a transceiver, not on a receiver! How to enable/disable back field detection is described in chapter 0. Power supply connections are not shown in the image but are described in 6.5. TRX RX BUS A1 BUS B1 BUS A BUS B FTP Receiver cable Back field control Aisle 1 No back field control Side A NoNeld fieX
Technical Manual AM Systems Connections v4.4 Page 37 of 72 6.13.3 Triple antenna system (double aisle) In case receivers are connected to the transceiver it is of great importance to connect the FTP and analogue connection cables to the proper connectors on the TRX and RX boards. Figure 22 shows the connections for a triple system (RX + TRX + RX). Figure 22: Triple antenna system connections In this system setup it is important that the FTP cable is connected to the proper bus to allow for the receiver lights to light up in case of an alarm. The receiver FTP cable has to be inserted into the transceiver board with reference to the side (A or B) of the transceiver on which the particular receiver is installed. Figure 22 shows receiver RX1 installed on the backside (side B) of transceiver TRX1. The FTP cable for RX1 then needs to be plugged into the BUS B connector of TRX1. RX2 is installed in front (side A) of TRX1 and the FTP cable for RX2 thus needs to be plugged into the BUS A connector of TRX1. Power supply connections are not shown in the image but are described in chapter 6.5.

Technical Manual AM Systems Connections v4.4 Page 38 of 72 6.13.4 Quad antenna system (triple aisle) In case four or more AM antennas need to be installed as one complete system, all antennas need to be connected as shown in Figure 23. Figure 23: Quad antenna system When a receiver is installed between two transceivers (RX1 in the above example), then this receiver needs to be connected to both transceivers through the analogue receiver cables to make this receiver detect tags in both aisle 2 and aisle 3. Backfield control is possible on those transceivers that are the first and/or last antenna of the row and the receiver is connected to BUS A of the transceiver. In this case the backfield detection of TRX1 can be either enabled or disabled. Backfield control on TRX2 is not possible, since this antenna is installed between two receivers. If no detection is required in aisle 2, then the receiver cable between TRX2 and RX1 can be disconnected. Backfield control on TRX1 and TRX2 will then be possible, if required. Power supply connections are not shown in the image but are described in chapter 6.5. 6.13.5 Large systems Large systems (more than 4 antennas) need to be installed as described in the previous section. If one complete Field Bus is required then all antennas need to be interconnected with FTP cable.

When the memory is full, the oldest alarm will be replaced with the newest alarm (FIFO principle). It is possible to view the alarm history per day for a maximum of the last 30 days or less, in case the maximum number of alarms has been reached within 30 days. Just click the Previous/Next day buttons to scroll through the alarm history.
Technical Manual AM Systems Cross Point Device Explorer v4.4 Page 55 of 72 8.7.5 Entrances – selected antenna If you click on a TRX or RX antenna in the 3D-view, some individual antenna settings can be configured. Transceiver (TRX) settings 8.7.5.1When a TRX antenna is selected in the 3D-view, the following tabs will appear at the bottom of the screen: Scope view 8.7.5.1.1The Scope view screen shows the signal that is received by the receiver part of the transceiver and/or separate receiver(s) that might be connected to the transceiver. Figure 42: Scope view Dependent of the number of connected receivers and whether the backfield of the transceiver is on or off, the Channel dropdown box lets you select the device that you want to work on The Scope view itself shows the signals that are being detected on the antenna’s 0-loop and 8-loop configuration (blue lines). The red line is the threshold level. The threshold level actually determines the sensitivity of the transceiver/receiver. A low threshold level creates a high sensitivity, where a high threshold level results in low sensitivity. When a signal (blue line) rises above the threshold level (red line), the alarm will be triggered.
Technical Manual AM Systems Cross Point Device Explorer v4.4 Page 56 of 72 The threshold level can be adjusted in two ways; automatically or manually Automatic threshold level adjustment Tick the Automatic threshold checkbox to activate automatic threshold level adjustment. Depending on the environmental noise levels, the transceiver will automatically and continuously adjust its threshold level higher than the noise levels. The Minimum threshold option will prevent the threshold level from getting too low, potentially making the system too sensitive. Manual threshold level adjustment Un-tick the Automatic threshold checkbox to activate manual threshold level adjustment. By entering a value manually or by pushing the up or down arrows, the required threshold level can be set. Alternatively, the slider next to the scope view can be moved up or down to set the required level. Sensitivity The sensitivity slider can be used to decrease or increase the total sensitivity of the antenna. The default value is 10 and you can increase the sensitivity to 20, or decrease it to 1. Noise The noise level indicator shows a value between zero and one hundred, which represents the amount of noise that’s being detected by this receiver. A high noise level will result in reduced detection, which means that specified detection distances might not be achieved. To improve this situation the noise source(s) must be located and removed. If removal of the noise source is not possible, the aisle width between the antennas needs to be reduced, which means that the transceiver and receiver antennas need to be installed closer to each other. Never adjust the antenna too sensitive, as this will result in false alarms! Remove the noise sources that interfere with the system or move the antennas as far as possible away from noise sources. Synchronization AM 8.7.5.2When multiple AM systems are installed in relative close vicinity of each other, it is of extreme high importance that the transmission bursts of all transmitters (transceivers) occur at the same moment. To be able to view and change the position of these transmission bursts, the Synchronization screen is available. When the Synchronization screen is open, the transmission burst of this transceiver is disabled. As a result of this, the transceiver and connected receiver(s) will not detect any tags! Make sure to leave this screen to enable detection of tags again. When the transmission bursts are not synchronized properly, false alarms and reduced sensitivity will be the result. The Synchronization screen will show exactly if and where other system transmission bursts are detected.
Technical Manual AM Systems Cross Point Device Explorer v4.4 Page 57 of 72 Figure 43 shows an example of faulty synchronization. Our system’s transmission burst (Burst window 1, indicated as a vertical orange bar) is at a different moment in time than the other system’s transmission burst, which is on its turn causing interference in our system’s detection window. Figure 43: AM synchronization – wrong adjustment Our system’s transmission burst window (orange bar) Our system’s detection window (red bar) Our system’s rereference window (green bar) Other system’s transmission bursts (blue curve)
Technical Manual AM Systems Cross Point Device Explorer v4.4 Page 58 of 72 We now have two ways of synchronizing the systems; manually or automatically. Manual synchronization By default the transmission burst can be synchronized manually by dragging and moving the burst throughout the complete 20ms time base. Just hover the mouse cursor over our transmission burst (the cursor will change to a horizontal double arrow) and press down your left mouse button. While keeping the mouse button pressed, move the transmission burst and position it on top of the other system’s transmission burst. Together with moving the transmission burst, also the receiver and reference windows will move automatically since they have a fixed reference to the transmission burst. Automatic synchronization It is also possible to let the software detect the best position for the transmission burst. Just click the Automatic Sync button and within 10 to 15 seconds the software will have determined the best burst offset position. Figure 44: Synchronization AM – correct adjustment Figure 44 shows our system being properly synchronized with the other system’s transmission burst. Our transmission burst is on top of the other system’s transmission burst and both our receiver and reference windows are not on top of any other transmission bursts.

Technical Manual AM Systems Cross Point Device Explorer v4.4 Page 59 of 72 Temporarily disabling other device bursts 8.7.5.2.1When you start synchronizing entrance(s), start by selecting the Synchronization page of the first device. It is very useful to switch the transmission bursts of all other entrances off, so you can determine if there are any other AM systems in the area, to which you must synchronize your system. To switch the transmission bursts of the other devices off, select the Automatic synchronization button to unfold a list of all other available devices. Click on the green checkmark in front of the device name to disable the transmission burst of that device.

Technical Manual AM Systems Cross Point Device Explorer v4.4 Page 61 of 72 Notifications – I/O settings 8.7.5.2.3Next to the audio and visual alarm notifications, as described in section 8.7.4.1, also a relay and a maximum of 2 I/O’s can be programmed to activate any external device (camera, external buzzer, etc.) during an alarm situation. These notification settings have to be programmed on each individual antenna, since the relay and I/O’s are antenna specific. Any externally connected device needs to be physically connected to the antenna. Figure 46: Notifications – I/O settings Relay and I/O notification settings apply only to an individual antenna! The following notification types can be selected by clicking on the cell in the top left corner of the notifications table: x Alarms x Metal x Visitors x Other Refer to section 8.7.4.1 to view all available notification types.
Technical Manual AM Systems Cross Point Device Explorer v4.4 Page 62 of 72 Tuning AM 8.7.5.2.4The AM transceiver is performing at its best when maximum power is being transmitted at 58kHz. The Tuning screen shows a graphical display of the top and bottom antenna loop tuning and their associated power. Figure 47: Tuning AM By changing the positions of the antenna jumpers on the transceiver board, you can find the positions for both loops where they have the highest voltage output at 58kHz (the vertical red line). The spot where the curves cross the red line is the actual transmitted power. A higher output will increase the performance of the AM system, where a lower output will result in less performance. Make combinations of transceiver jumpers TUNE TOP1, TUNE TOP2, TUNE TOP3 to achieve the highest voltage for the top antenna loop and do the same for the bottom antenna loop using jumpers TUNE BOT1, TUNE BOT2 and TUNE BOT3.

Technical Manual AM Systems Cross Point Device Explorer v4.4 Page 63 of 72 Antenna tuning assistant It can also be useful to use the Jumper settings assistant to determine the best jumper positions. Just click the positions of the jumpers in the Current image to indicate the current position of the jumpers on the board. Then click the Check button and the Advised image will show the advised jumper settings for optimal performance. Figure 49: Tuning assistant example Be aware of the high antenna voltages! Switch the power supply to the transceiver board off before tuning. Do not touch the backside of the transceiver board or the metal tuning jumper pins when the board is powered, as this might result in you receiving an electrical shock! Tolerances in the components of the transceiver board make it possible that the actual antenna jumper settings are different for each transceiver board and therefore the above image might differ for each transceiver board. When the Tuning screen is open, detection of tags is disabled. Make sure to switch to another screen if you want to test the detection performance! 1) Click on the jumpers to indicate your current setting 2) Press the Check button 3) The advised jumper setting will be shown
