 18  AR 400 Reader User’s Manual  2003-2004 Matrics, Inc. Create Read Point Classes A read point is an individually addressable antenna. Every read point must have a read point class associated with it, which is where you define certain parameters in an effort to fine tune the performance and characteristics of the read point. Multiple read points may share a single read point class. So, once you define a read point class, you can re-use it many times without re-entering the same parameters over and over again. You can add a new read point class from scratch (naming it and specifically setting its parameters), or you can use an existing read point class as a template (copying its settings, and renaming it.) 1.  If you haven’t already done so, launch and log in to the Reader Administrator Console. 2.  Click the Read Point Class link on the left-hand side of any page. The Read Point Classes page displays.  3.  To add a new read point class, enter the following information:   A unique Class Name (one that does not already exist in the system),   The antenna Type--AREA (long range), SHELFv1 (existing short range shelf type), SHELFv2 (next generation short range shelf type), COMBINED1, or COMBINED2,   Set the Scan Period to tell how often the read point is to be checked for tags,   Set the Gain (as a percentage) to designate the antenna’s power setting,
  AR 400 Reader User’s Manual  2003-2004 Matrics, Inc.  19   Set Retry to tell the Reader how many times to repeat the read command each time a scan is to be performed,    Set Air Protocol to All, Class 0, or Class 1 to tell the Reader which protocol to use to interrogate tags, and   Set Tag Selection to designate which tags to read. After typing the required information, click the Add Class button. If the data is valid, the read point class is added and the Class List updated. NOTE: Your physical Reader configuration is not updated until you click Commit [refer to the “Save or Discard Changes (or Revert to Backup)” section in this manual for more information.] If not successful, the system should indicate the problem and allow you to correct it by repeating the operation. 4.  To create a new read point class by copying an existing class, select the existing class’ name in the Class List, and then click the Select Class button. The values of the existing class are copied (including the name.) Change the name of the copied class, and then click Add/Modify Class. A new read point class is created. 5.

  AR 400 Reader User’s Manual  2003-2004 Matrics, Inc.  23 Configure the Reader The Reader Administrator Console’s Reader Configuration pages allow you to logically describe the antenna connections of your physical Reader, so that the AR 400 Reader can communicate to other systems the connectivity and parameters of the devices. Before you use the Reader Administrator Console to define the configuration of your Reader, you must gather certain information about your physical devices from the personnel who installed them. For example, you will need to know what types of devices are connected to each port and the parameters associated with those devices. You also need to know the network configuration parameters (such as IP addresses, netmask and default gateway, etc.) Once you have obtained the information you need about your physical devices, you can access the dynamic web pages in the Reader Administrator Console, which act as a wizard to walk you through the process of defining your Reader configuration and the association of its devices. By default, a standard Reader configuration is displayed with a Reader link and links for four Reader ports. A port can connect directly to a read point (antenna), or combine with a subsequent port to connect to a splitter. The following list describes the four possible port combinations:    4 Ports -- All four ports connect directly to read points.    1 Splitter + 2 Ports -- The first two ports connect to one splitter, the other two connect directly to read points.    2 Ports + 1 Splitter -- The first two ports connect directly to read points, the other two connect to one splitter.    2 Splitters -- The first two ports connect to one splitter, the other two connect to another splitter.  The current Reader port status (direct port or splitter port) determines what kind of read points can be attached to this specific port. In other words, it determines what Read Point Class types can be used with this attached read point, essentially determining a subset of compatible Read Point Classes with these types.   If a port connects to a read point directly, the link for the read point provides access to its parameters.    If a port is empty, Add ReadPoint and Add Splitter links are displayed.    If a splitter is used: o  If a read point has not been added yet to this splitter, a Delete Splitter link is provided if you want to remove the splitter, and an Add ReadPoint link is provided if you want to add a read point to the splitter.  o  If a read point has been added to this splitter, the only link provided is to access to the read point’s parameters.

 36  AR 400 Reader User’s Manual  2003-2004 Matrics, Inc. Section 6. Notification of Events Events Overview The AR 400 Reader generates several types of events: Visibility and Threshold Events that report tag activity; and Network Status and Exception Events that report device/system activity. If you want to be notified when particular events occur, you can choose (subscribe to) these events via the Event Notifications page. You may also choose whether or not you want to receive any event notifications at all. Visibility Events There are three types of Visibility Events that are generated when changes in tag visibility occur:   New Tag Event— A New Tag Event is a special case event generated to notify you when a new tag appears for the first time. A new tag is one that has never been seen before, and has not previously been known to the Reader. You can then commission the tag (or associate an User ID and a threshold rule to the tag.) This event should be processed in a timely fashion to give meaningful results, so set the Notify option to Immediate (the default for this event type). If you don’t want to be notified when this type of event occurs, set the Notify option to Never, in which case the event is promoted to a generic Visibility Changed Event.   Tag Not Visible Event—A Tag Not Visible Event is a special case event generated to notify you when a tag is not currently visible to any Read Point. For example, if a tagged item is removed from a shelf and is out of RF range (not being seen by any Read Point), then a Tag Not Visible Event would apply. The Event reports where the tag was located when last visible to the system. Since there may be cases, in the normal course of operation, that a tag has transient periods when it is changing visibility in the system, set the Notify option to Moderated to smooth out temporary conditions, and generate an event only when the tag is no longer being actively tracked. (The AR 400 Reader still knows about the tag, but it is not visible to any Read Point.) If you don’t want to be notified when this type of event occurs, set the Notify option to Never, in which case the event is promoted to a generic Visibility Changed Event.   Visibility Changed Event—A Visibility Changed Event is a generic event (not as specific as a New Tag or Tag Not Visible Event) generated any time that the visibility of a tag changes. The visibility change may be due to more, less, different, or even no Read Points being associated with a tag. For example, if a tagged item moves from a shelf on aisle 2 to another shelf on aisle 4 (visibility changes from one Read Point to another), then a Visibility Changed Event would apply.  Note: If you have enabled Tag Not Visible Events, then a tag not currently visible to any Read Point(s) will generate the more specific Tag Not Visible Event instead. Likewise, a New Tag Event will be generated for the first visibility change when applicable.
  AR 400 Reader User’s Manual  2003-2004 Matrics, Inc.  37 This event should be processed in a timely fashion to give meaningful results, so set the Notify option to Immediate (the default for this event type.) Threshold Events A Threshold Event is generated when the number of visible tags drops below or rises above a threshold that you specify via a Tag List notification reply. Before you can generate Thresholds Events, you must import and associate rules for your thresholds. Since some users may not want to set up rules and thresholds, by default, this event’s notify option is set to Never. Threshold events are only generated when the notify option is enabled, and User IDs and thresholds have been supplied via a Tag List. Since there may be cases, in the normal course of operation, that a tag may have transient periods when it is changing visibility in the system, set the Notify option to Moderated to smooth out temporary conditions, and generate an event only when the tag is not experiencing a temporary moment of invisibility.  Network Status Events Network Status Events alert you to changes in status of the managed resources of the Reader. For example, if a Reader problem is detected, an event is generated by the Reader and sent without a server request. If you want to receive Network Status Event notifications, you must subscribe to them by setting the SNMP configuration on the Event Notifications page. If the SNMP host is not set (or is not valid), no Network Status Events will be sent Network Status Events are divided into two categories, ‘device’ and ‘program.’ A Device Event notes the change in a device’s status. A Device Event is further divided into two categories, ‘user’ and ‘system.’ Both categories have an addition specification as to whether the status change is being reported for itself or in association with a ‘parent’ device. For example, if the ‘user’ disabled a Reader, several events would be generated. The Reader would get a ‘user/disable’ status notification. The Read Point(s) below the Reader would get a ‘user/disable/parent’ notification. If the system detected a problem with the Reader, it would automatically disable the device, and the matching events would be generated. These classifications allow you to not only see the overall effect on the Reader Network, but also allow the likely offending component to be identified. When the fault is fixed, you can ‘enable’ the device. Any device below it that was ‘parent disabled’ is automatically brought back online. Exception Events Exception Events provide the same type of information available via SNMP, except over XML. An Exception Event gives you information when a device goes off-line, polling is turned off, etc.. You may choose this option if you don’t support SNMP, but still want to receive feedback if the device/program changes state. XML is enabled by setting the Notify option for Exception Events to ‘Immediate’ in the Notify column on the Event Notifications page.

 50  AR 400 Reader User’s Manual  2003-2004 Matrics, Inc. Section 8. Reader Server Controls While most of the Reader Administrative Console functions allow you to create a logical view of your Reader, the Reader Server Status and Scan Control pages give you a view of (and control over) the actual “running” system configuration.  Check Status of Reader The AR 400 Reader monitors the health and welfare of Readers and associated devices. Under normal circumstances, the table displayed on the Reader Status page should show the same number of devices in the Total column and the Enabled column. However, if devices are off-line (not enabled), you will see a non-zero number in some of the other columns. 1.  If you haven’t already done so, launch and log in to the Reader Administrator Console. 2. Click the Status link on the left-hand side of any page. The Reader Status page displays.  If you have disabled a device, you will see an entry in the User Disabled column. User-disabled devices can be enabled via the Reader Configuration page. If there are child devices (lower in the hierarchy) such as Read Points connected to a Reader that you have disabled, a value displays in the Parent Disabled column.
  AR 400 Reader User’s Manual  2003-2004 Matrics, Inc.  51 During the operation of the system, if a device becomes non-operational, the system will disable it automatically, but allow the rest of the system to continue to operate. If this happens, a SNMP trap is generated, the appropriate device or devices are marked as system-disabled, child devices are marked as parent-disabled, and a non-zero entry (link) displays in the System Disabled column. For devices with multiple read points (such as a shelf), a read point can become non-operational (its status changing to “degraded”) while its other read points continue to operate. An additional value displays in the Enabled column for a degraded device. For example, if four read points were enabled and one of them became degraded, “4/1” would display in the Enabled column. The “1” links to a list of degraded devices, allowing you to enable degraded devices like you would a system-disabled device. 3.  To attempt to re-enable a system-disabled device, click the link in the System Disabled column, and the associated Enable Device page displays. Select a device to enable and then click Enable Device, or click Enable All Devices to attempt to enable all devices. If the device(s) is successfully brought back into service, it will automatically enable all of the parent-disabled children, and it will be removed from the Disabled lists. 4.  If you want to automatically attempt to re-enable degraded or system-disabled devices after a specified number of minutes, type the number of minutes in the Automatic Enable Period field on the Reader Status page, and then click Set Auto Enable Period. 5.  Information displayed in the System Clock field tells you the time on the Reader. When tags are seen and/or events are generated, they are time-stamped with this time value. To change the time, click the link. The System Time Management page displays. Select the appropriate values from the Year, Month, Day, Hour, Minute, and Second drop-down list boxes, and then click Set Date and Time.  6.  Information displayed in the System Up Time field tells you how long it has been running since the system was last rebooted. The System Up Time field value is reset automatically each time the Reader is rebooted.
