Section 4. Installing the Reader The instructions provided in this section describe a generic installation of the AR 400 Reader. Depending upon your application, your installation steps may vary. Contact Matrics (refer to the “Contact Us” section in this User’s Manual) if you need further assistance for a customized installation. Follow the steps listed below (and detailed in the following sections) to install and test your AR 400 Reader: 1.
Mount the Reader Before mounting the Reader, you must select a location for it. For best results, consider the following when determining the optimal placement for your Reader: Mount the Reader indoors, in operating range, and out of direct sunlight, high moisture, or extreme temperatures. Mount the Reader in an area free from electromagnetic interference.
Connect Antenna(s) to the Reader Attach your antenna(s) to the Reader in sequential order (first connecting Antenna 1 to Reader connectors Tx1 and Rx1, then Antenna 2 to Reader connectors Tx2 and Rx2, Antenna 3 to the Tx3/Rx3 connectors next, and Antenna 4 to the Tx4/Rx4 connectors last.) 1. Attach the large ends of your antenna connector cables to the large connectors on the antenna. 2.
Verify the Reader Installation Reader On? After you have installed the AR 400 Reader as described in this User’s Manual, test that the Reader is on by following the instructions provided above in the “Power on (and Off) the Reader” section. To verify that the Reader is operational, power it on by plugging the power supply (attached to the Reader) into the appropriate power outlet. The green Power/Link LED on the Reader should turn on, indicating that the Reader is powered on and the system is operational.
Section 5. Configuring the Reader Follow the steps listed below (and detailed in the following sections) to configure your AR 400 Reader: 1. 2. 3. 4. 5. Launch and log in to the Reader Administrator Console via its Web interface. Familiarize yourself with the system by using the Setup Wizard and/or Online Help. Create standard Read Point configurations (via the Read Point Class and Read Point Zone pages.) Perform the basic configuration of Reader Ports (via the Configuration page.
For subsequent logins, after you’ve created users (refer to the “Manage Users” section in this manual for more information), type your user name in the User Name field, your password in the Password field, and then click Login. The Main page displays. The Main page provides an informational list of Reader functions, and links to each of the Reader’s dynamic web pages. Click a link on the left-hand side of the Main page to display the corresponding page.
Use Setup Wizard The Setup Wizard walks you through a test setup of the system to familiarize you with the process of configuring a system. 1. If you haven’t already done so, launch and log in to the Reader Administrator Console. 2. Click the Setup Wizard link on the left-hand side of the main page. The Reader Administrator Console Configuration Wizard page displays.
Use Online Help The Help pages provide easy online access to conceptual and procedural information related to the Reader Administrative and Maintenance Consoles. 1. If you haven’t already done so, launch and log in to the Reader Administrator Console. 2. To view Help for the Administrator Console, click the Help link on the left-hand side of any page in the Administrator Console. The Administrator Console Help page displays in a separate window.
Save or Discard Changes (or Revert to Backup) Whenever you add or make modifications to your Reader configuration using the Reader Administrator Console, the changes are not immediately applied to the underlying physical Reader Network of hardware components and networked connections. You must click Commit to save the changes and notify the Reader to update its configuration file, which updates your physical Reader configuration.
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.
• • • 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.
Modify the parameters as needed, and then click Add/Modify Class. NOTE: If you modify the class’ name, a new class is created. If you modify the class’ parameters and DO NOT modify its name, then the existing class is updated with the changes you made to its parameters. When you modify a read point class’ parameters, all read points that are associated with that class are automatically updated. 6.
Create Read Point Zones While you are not required to create or use them, read point zones allow you to group several read points in a logical, customized manner. For example, you might create a zone named Warehouse XYZ to group all read points installed in a particular warehouse area, or Store ABC to group all read points installed in a particular retail location. A default zone (named ‘Default’) is provided for you. 1. If you haven’t already done so, launch and log in to the Reader Administrator Console.
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 modify a read point zone, select the zone’s name in the Zone List, and then click Select Zone.
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.
