2.1.1

Field Bus Network structure Both transceiver and receiver are interconnected through CAT5 wiring and can be connected to a host (e.g. a Field Controller 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. If no controller is used, various parameters can be set on each board separately. All this functionality functionality is described described further on in this manual. manual.

2.1.2

Visitor counting Visitor counting for an aisle is possible because bi-directional IR-based visitor counter modules, installed in the top of the antennas (optional), can be connected to the NEXUS AM boards. A NEXUS AM transceiver antenna is equipped with a visitor counter receiver module and a receiver antenna with a visitor counter transmitter module. 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 counter modules. Partly this extra functionality can be used by using the NEXUS AM boards, but most extra functionality can be added by connecting it to a controller or computer. Some of the extra functionality is listed below. •

Introduction

2.1.3

Restrictions and limitations The following restrictions and limitations must be considered:

2.1.3.1

NEXUS AM versus NEXUS RF It is not allowed not allowed to connect NEXUS AM systems together with NEXUS RF systems to the same Field Bus! Pins 3 and 6 on BUS A and BUS B of the NEXUS AM transceiver and receiver boards are not interconnected. They are used for communication communication between the NEXUS AM transceiver and the NEXUS AM receiver. On NEXUS RF systems, pins 3 and 6 are used for synchronization purposes between the NEXUS RF transmitter and the NEXUS RF receiver, which is based on a completely different signal. Connecting NEXUS AM and NEXUS RF systems to the same Field Bus will result in bad performance and synchronization and must be avoided!

2.1.3.2

NEXUS Mono restrictions Since the NEXUS AM transceiver is equipped with a visitor counter receiver only, it will not be possible to use the visitor counting feature when two or more transceivers are installed next to each other. TRX2

General AM and EAS issues This chapter covers the various issues related to Acoustic Magnetic systems and Electronic Article Surveillance systems in general, like:

3.1

•

Noise sources

•

Installation guidelines

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: •

•

•

•

Any electronic electronic device that operates around 58kHz 58kHz or produces produces harmonic frequencies around 58kHz. (Moving) Objects containing containing metal, like like sliding sliding and and revolving revolving doors, elevators, escalators, roller shutters, frames, etc. Electronic devices, like computers, screens, cash registers, engines, transformers, etc.

•

Vertically positioned power cables, both low voltage voltage and high voltage.

•

Lights (flashing, fluorescent, halogen, gas-de-charge, gas-de-charge, etc.)

•

3.2

AM systems systems installed installed in other shops shops (even (even if they are installed up to 100m or more away from your store).

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.

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 entrance/exit carefully for possible 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 connect a TRX or a set of antennas antennas (1 TRX and 1 RX) 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 antenna on that side where the highest noise noise is or where the highest noise can be expected. 4. Install the power power supply for the EAS system 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 1mm 2) 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 NEXUS AM system. 5. Avoid unnecessary unnecessary long cables. Run the power supply cables 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 entrance/exit doorframe). 6. By default the shielding shielding of shielded shielded cables is not 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 connect more than than 1 transceiver transceiver antenna to 1 power supply. 8. Metal framed doors may never swing swing between between the EAS 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 connect unshielded unshielded and untwisted untwisted cables 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.

4.3

Converter The various transceivers and receivers are interconnected interconnected through the Cross Point Field Bus (see Bus (see chapter 6.3, page 16 for further details on the Field bus structure). To be able to connect the Field Bus to the laptop a converter is required. Depending on the type of available communication ports of your laptop or PC, you will either need a USB/RS-485 converter or an RS-232/RS-485 converter. The recommended converter is the NEXUS Multi Converter . Cross Point can supply the NEXUS Multi Converter, which contains an RS-485/USB converter as well as an RS-485/RS-232 converter. RJ45 connectors enable easy connection of the Field Bus devices through FTP cable. Please refer to the Technical manual Multi Converter for further details on all features of this converter.

AM operating principle The NEXUS AM operates on the pulse-listening principle. 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 50Hz mains frequency cycle is dived into into three phases; phase phase A, B and C. Each phase covers 1/3 of the 50Hz cycle duration. A noise reference reference window is opened opened to detect the environmental noise. noise. This signal is compared with the signal received in the receiver window and allows the software to properly distinguish a t ag signal from a noise signal. Figure 2 shows the AM operating principle (at 50Hz, with a default delay of 200µs) during one 50Hz cycle. T r a n s m i s s i o n b u r s t

5.1

Synchronization principle When multiple AM systems are installed in each others 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 3 shows two AM systems that are not properly synchronized. synchronized. T r a n s m i s s i o n b u r s t

System B

Figure 3: 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 4). This will result in both systems working properly without interference (see Figure 5).

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 NEXUS antenna has a front side (A) and a back side (B). These sides are indicated on the visitor counter on the top 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 6.8 (page 33)) try to put all antenna’s in the AB-AB pattern, i.e. all antennas should be placed in the same way. RX1

Connections

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 hand on top of the top part 2. Put your right right hand around the antenna frame frame on the right side of the antenna 3. While pushing pushing the top part to the right right with your your left hand, push the top part up with the thumb of your right hand. This will unlock the magnets and the ‘click’ locking mechanism and the top part can be removed 4. Slide the Plexiglas Plexiglas plate on side A of the antenna upwards. 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 f rom falling down and causing an injury. 5. Unlock the screws screws in the front front cover (side A). A). 6. Remove the front cover.

Connections

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. IMPORTANT: The Cross Point Field Bus requires the devices to be connected in a “daisy chain” connection. A “star” network is not allowed and allowed and will result in poor communication communication between the devices and the t he host computer or controller! Each device (TRX PCB and RX PCB) has a unique address (this address is factory set and cannot be changed) and a PC/laptop enables local maintenance of the TRX and RX boards by using the Field Bus Analyzer software. When the Field Bus is connected to the Field Controller and the Field Controller is connected to a Local Area Network (LAN), local servicing and data retrieval is possible. When an ADSL connection is available, the Field Controller can also be connected to the Internet, which enables changing of TRX or RX settings and information read-out from a remote location over the Internet.

6.3.1

Bus connections with laptop Figure 7 shows the Field Bus structure between the various antennas. Connecting the Field Bus to a laptop (through an RS-485/USB converter) allows on-site maintenance through the Field Bus Analyzer software.

I/O connections The NEXUS 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!

The visitor counter The NEXUS AM is 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 22 shows the visitor counter principle.

Figure 22: 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. NOTE

Not switching off the unused visitor counter sides may result in incorrect customer counting totals. 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. See chapter 8.8.7.2 (page 65) on how to change the various TRX visitor counter settings and chapter 8.9.4.2 (page 84) on how to change the various RX visitor counter settings. 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).

Various connections For proper operation of the NEXUS AM system it is very important to interconnect the transceivers and receivers in the correct way. This chapter shows and explains these various connections.

6.9.1

Single antenna system (no aisle) The NEXUS AM system can be used as a single antenna system (mono). When no receivers no receivers are connected to the transceiver, the transceiver will automatically function as a mono antenna system. Visitor counting is not possible. TRX1

Figure 23: Single antenna system

6.9.1.1

Multiple transceivers In case only transceivers are used, the transceivers can either be used as complete stand-alone antennas, 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. TRX1

6.9.2.1

Backfield control When 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 Bside 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 8.8.7.4.1 (page 71). Power supply connections are not shown in the image but are described in chapter 6.4.3 (page 19).

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 26 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 6.4.3.

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 transceivers that are the first f irst 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. 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 6.4.3.

Visitor counter The integrated visitor counter will register the number of people entering the store and the number of people leaving the store. The Visitor counter screen screen (Figure 50) shows the visitor counter configuration and settings.

Figure 50: Visitor counting

Counter configuration: The counter configuration section shows the current TRX antenna (top view) and the neighboring RX antennas. Select either the A-side or B-Side or both (depending on the actual installed RX antennas) by marking the corresponding corresponding checkbox. Make sure to deselect the side which is not used to prevent errors being reported by the TRX board. The number of counted visitors as shown in the image is real-time updated when a visitor passes between the antennas. Notifications for incoming (door bell) and outgoing visitors, as well as visitor counter blocked have to be set in the Notifications screen Notifications screen (see section TRX Notifications, page 61). By default the “Today totals” are shown, but selecting the “Totals since installation” option will show the totals since the system was installed or since the last time the values were reset to zero. The counter values can be reset to zero by clicking the Reset values button. values button. The in/out direction indication can be changed by selecting the “Change direction” option.


65

Alarm configuration: Use visitor counter to distinguish in- and outgoing alarms The visitor counter can be used to determine the movement direction of a person who creates an alarm. Marking the checkbox will activate this feature. If this property is switched off, it is not possible to have difference in alarm indication and a general alarm indication will be generated. In order for the TRX to detect in which direction the person is moving, a short delay between a detected tag and a detected person needs to be applied. This delay time can be selected behind the “Wait “ Wait time between tag detection and counter activity” activity ” property. The available delay times are 1, 2, 3, 4 or 5 seconds. If the customer counter detects a person within the specified delay time, the movement direction of this person will be associated with the detected tag and an alarm will be generated accordingly. accordingly. If the customer counter doesn’t detect a person within the specified delay time, the generated alarm will be an “undefined” alarm. In case a pre-alarm (visual, audible or silent indication that a tag has been detected, but the movement direction has not yet been determined) is required, the “Tag detected” notification needs to be set (see section TRX Notifications, page 61).

8.8.7.3

Synchronization When 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 synchronize these transmission bursts, the Synchronization Synchronization screen is available. IMPORTANT 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.

Other system(s) transmission burst(s)

Our system transmission burst (blue vertical bar)

Our system receiver window (green vertical bar)

Our system reference window (orange vertical bar)

Figure 51: Synchronization - faulty

When the transmission burst are not synchronized properly, false alarms and reduced sensitivity will be the result. The Synchronization Synchronization screen will show exactly if and where other system transmission bursts are detected. The above screenshot shows an example of faulty synchronization. Our system’s transmission burst (Burst window 1, indicated as a vertical blue bar) is at a different moment in time than the other system’s transmission burst. Synchronization mode Before starting the synchronization procedure, you must select the synchronization synchronization mode. The following options are available: 1. Switch off all other transceivers transceivers – this option will switch off all other transceivers that are part of this Field Bus. This way you will know for


67

sure that all transceivers are switched off and the signal that might still be visible in the synchronization window is indeed another AM system which is not part of your installation. Start with this option when you synchronize the first transceiver in your installation. If no other AM systems are visible, then leave the offset value at the default value of 0.2ms. When other AM systems are visible, synchronize your transceiver with the other AM system as described under Manual or Automatic synchronization. 2. Switch off all other transceivers except: except : - this option will switch off all other transceivers that are part of this Field Bus, except the one that is selected from the drop down box. Use this option for all other transceivers that are part of your installation. Select the first transceiver, the one you have synchronized in the previous step, from the drop down box and synchronize all other transceivers with the first transceiver as described under Manual or Automatic synchronization. 3. All other transceivers will remain bursting bursting – this option will leave all other transceivers bursting. All other transceiver bursts will thus be visible in the synchronization window. Make sure to properly synchronize all bursts as described under Manual or Automatic synchronization.

68


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 throughou t hroughoutt 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 the Automatic Sync button button and within 10 to 15 seconds the software will have determined the best burst offset position. Once the automatic synchronization process has finished, you will be prompted to select the advised offset value, or select one of the alternative offset values that have also automatically been determined.

Figure 52 shows our system being properly synchronized with the other system 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 not on top of any transmission bursts.

Also one or more of the following options can be visible depending on the number of connected receivers and the way they are connected:

8.8.7.4.1

Minimize backfield When this option is enabled, back field control will be activated and the detection on the back-side of this transceiver antenna will be reduced. See section 6.9.2.1 for further details on back field control.

8.8.7.4.2

Disable side A By default side A is enabled, which means that the transceiver will switch off its own internal receiver part for this side and expects a receiver to be connected to the transceiver’s bus A and bus A1. Ticking this box will disable side A of the transceiver antenna. The transceiver will activate its own internal receiver part for this side, disregarding any receiver that might be connected to the transceiver’s bus A.

8.8.7.4.3

Disable side B This has the same effect for side B as described above for the “Disable side A” option.

8.8.7.4.4

Sampling Pressing the Pause button will stop the sampling routine and the receiver signal windows will no longer be updated with new information. Press the Play button

to start sampling again.

Depending on the number of connected receivers, either one or two receiver signal windows will be visible. In case two receiver signal windows are shown, the individual windows can be enlarged by selecting one of the zoom buttons. Show upper receiver signal window only Show both receiver signal windows Show lower receiver signal window only

Figure 54: Receiver signal window

After pressing the Play Play button, the receiver signal window will be updated with new information. The signals will scroll to the left, leaving a 10 seconds signal history visible. When no AM tag or other AM system which is not properly synchronized is within the vicinity of the system, the receiver signal window should look similar to the one in Figure 54. When an AM tag is presented to the system, the receiver signal window should look similar to Figure 55.

If this is the case then one ore more of the following possibilities can be the cause: 1. An AM tag is positioned positioned too close to the antennas antennas Solution: Solution: Locate and remove the tags(s) 2. Another AM AM system is is not properly properly synchronized synchronized and is interfering with our receiver Solution: Solution: Properly synchronize all AM systems in the area If the cause for this high signal can’t be eliminated, eliminated, then the only solution is to increase the threshold level and set it higher than the highest signal level.


73

8.8.7.5

Threshold level adjustment The threshold level actually determines the sensitivity of the transceiver/receiver. transceiver/receiver. A low threshold level creates a high sensitivity, where a high threshold level results in low sensitivity. When a tag signal rises above the threshold level, the alarm will be triggered. 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. Figure 53 shows automatic threshold level adjustment for transceiver TRX1. Depending on the environmental environmental noise levels, the transceiver will automatically and continuously adjust its threshold level higher than the noise levels. Manual threshold level adjustment: Un-tick the Automatic threshold checkbox to activate manual threshold level adjustment. Figure 53 shows manual threshold level adjustment for receiver RX1. By entering a value manually or by pushing the up or down arrows, the required threshold level can be set.

8.8.7.6

Tuning The NEXUS AM transmitter is performing at its best when maximum power is being transmitted at 58kHz. The Tuning screen Tuning screen (Figure 57) shows a graphical display of the top and bottom antenna loop tuning and their associated power.

Top antenna loop

Bottom antenna loop

Figure 57: Transmitter antenna tuning

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 orange line). The spot where the curves cross the orange line is the actual transmitted power. A higher output will increase the performance of the NEXUS AM, where a lower output will result in less performance. Make combinations of transceiver jumpers TUNE TOP1, TUNE TOP2, T UNE 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.

In the above example image the maximum achievable top antenna loop power is 1160V and the bottom antenna loop power is 1300V.

WARNING! 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. NOTE 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. performance.

8.8.7.6.1

76

Changing the transmission power Sometimes it can be necessary to reduce or increase the amount of transmitted 58kHz signal to achieve better detection results. For t hat reason the transceiver output power can be regulated through increasing increasing or decreasing the power supply voltage. This can be done in the Properties screen of the transceiver.

All entrances The All The All entrances screen entrances screen enables automatic arrangement of the connected antennas. Figure 64 shows the All the All entrances window before an antenna arrangement has been executed.

8.10.1.1

Antenna arrangement The antenna arrangement is based on the detected devices and will be arranged automatically when the Arrange button is pressed. The integrated visitor counters are used to determine which antennas belong to what aisle and entrance. Before pressing the Arrange button check and meet the following preconditions preconditions before continuing the antenna arrangement. •

All antennas must be properly aligned

•

There should be no no obstructions obstructions between the antennas antennas

•

•

The infra-red infra-red transmitters transmitters and receivers of the visitor counters counters should should not be covered in any way The installer installer access code for all devices devices must be be the same same and must be properly set in each device

IMPORTANT: If these preconditions are not met then antenna arrangement might fail or the arrangement might not show the actual representation. Also note that the current current antenna layout layout will be lost lost after an automatic antenna arrangement arrangement and will be replaced by the new detected layout. IMPORTANT: Do not walk through the aisles during antenna arrangement, arrangement, as this t his interrupts the people counter’s infra-red beams and might result in wrong antenna arrangement. The whole antenna arrangement process takes several seconds (actual time depends on the number of antennas). During antenna arrangement a progress indicator will show the progress. After the antenna arrangement arrangement process process has finished, finished, the result will be shown shown in a graphical representation. representation. If the result does not match the actual situation, check whether the preconditions preconditions have been met en restart the arrangement process by pressing the Arrange button again. Figure 65 shows a successful antenna arrangement of all antennas.
