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:   MAXUS AM50 Mono   MAXUS AM50 Receiver   MAXUS AM50 Mono Advertising   MAXUS AM50 Receiver Advertising   STYLUS AM30 Mono   STYLUS AM30 Receiver   FORTUS AM40 Mono   FORTUS AM40 Receiver   NEXUS AM30 Mono    NEXUS AM30 Receiver   MODUS AM30 Mono   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.   Automatic antenna arrangement   Possibility  to  count  customers  per  aisle  and  to  determine  the  direction  of movement (in or out of the shop)   Showing the importance of the alarm (is a customer moving in or out during the alarm)   Detecting undefined alarms   Pinpoint the exact aisle where the alarm occurred   Generate reports on visitor counts and alarm counts   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:   No visitor counting, doorbell or auto antenna arrangement   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:   Noise sources   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:   AM  systems  installed in  other  shops  (even  if  they  are  installed  up  to  100m  or more away from your store).   Any  electronic  device  that  operates  around  58kHz  or  produces  harmonic frequencies around 58kHz.   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.   (Moving)  Objects  containing  metal,  like  sliding  and  revolving  doors,  elevators, escalators, roller shutters, frames, etc.   Electronic devices, like computers, laptop screens, LCD screens, cash registers, engines, transformers, etc.   Vertically positioned power cables, both low voltage and high voltage.   Lights (flashing, fluorescent, halogen, gas-de-charge, etc.)   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:   Intel 1.3GHz or faster processor   Microsoft Windows Vista with Service Pack 2 (32 bit and 64 bit)   Microsoft Windows 7 or 8 with Service Pack 1 (32 bit and 64 bit)   Microsoft .NET Framework 3.5 Service Pack 1   512MB of RAM (1024MB recommended)   50MB of available hard-disk space for Device Explorer   Minimal screen resolution 1024x768 (recommended 1600x1200)   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.

By default the power supply is set to 230VAC mains input, but if required, the mains input can be switched to 115VAC. Follow the next steps to switch to a different mains voltage: 1.  Disconnect from mains power and carefully open the power supply housing 2.  Locate the internal switch and switch it to the required position 3.  Replace the external fuse with the correct value (see Table 2) 4.  Carefully close the power supply housing 6.8  Power supply restrictions This  power  supply  has  the  following  restrictions  which  must  be  respected  carefully  in order to warrant the safety of the product and user:   Only to be used in combination with AM systems   For indoor use only   Disconnect from mains power before opening the housing   Do not cover the ventilation holes of the housing
Technical Manual AM Systems        Connections  v4.4  Page 21 of 72   Leave at least 10cm of free space around the PSU for ventilation purposes   Allow for free air flow around the PSU   Local laws and regulations must be respected when installing and servicing this device   Minimum distance between PSU and AM system is 1m.   It is prohibited to connect more than one TRX to a power supply. Use a separate power supply for each TRX antenna!  Keeping the power supply principle in mind, the following power supply connections are recommended: 6.8.1  Power supply for a single system (mono) In a single antenna system setup (1 or multiple transceivers), a power supply must be connected to each individual TRX antenna.

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 “+”.

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.

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.

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.

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.

Technical Manual AM Systems        Cross Point Device Explorer  v4.4  Page 54 of 72  Alarm history 8.7.4.2The Alarm history screen shows a list of the tags that have been detected on all antennas in this entrance.  Figure 41: Alarm history  Dependent  of  the  notification  settings,  the  incoming  ,  outgoing    and  undefined   alarms can be distinguished by means of their individually colored icons. By default all types of alarms are displayed, but pressing one or more of the filter buttons  will show or hide the selected alarms. Click the Delete button   to delete all alarms in the list and to permanently remove them from all the connected antennas in this entrance. All alarms are date & time stamped, so it’s easy to find out when they occurred. For AM systems a maximum of 338 alarms can be stored in the memory of each AM TRX board. 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. The disabled icon   will appear, indicating the transmission burst for that device is switched off. Click this icon again to switch the burst on again. When you leave  the  Synchronization  page,  all  disabled  devices  will automatically start bursting again.

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!

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.

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
