Introduction The AR400 Reader is a ready-to-connect network element that offers a variety of options for connecting to corporate networks via Ethernet or serial connections. A Setup Wizard facilitates reader configuration. RFID Technology Radio Frequency Identification (RFID) is an advanced automatic identification (Auto ID) technology that uses radio frequency signals to identify “tagged” items. A typical RFID system consists of transponders called tags, readers, and antennas, which function as follows: • An RFID tag contains a chip that can store a limited amount of data. This data may be pre-encoded or can be encoded in the field. Tags come in a variety of shapes and sizes. • A reader sends out radio frequency waves using attached antennas. This RF field powers and charges the tags, which are tuned to receive radio waves. The tags use this power to transmit data back to the reader, which the reader converts to a format for computer storage. The computer application translates the data into an understandable format. Reader and AntennaHost ComputerPhysical/NetworkConnectionRF Wave andResponseTags Figure 1-1. RFID System Elements RFID Components Symbol’s RFID solutions offer low cost, long read range, and a very high read rate, providing real-time, end-to-end visibility of products and assets in the factory, distribution center, retail outlet, or other facility. A typical Symbol RFID system consists of the following components: • Silicon-based RFID tags that can be attached to vehicles, trailers, containers, pallets, boxes, etc. • Different types of antennas to support applications such as dock door (area antennas), conveyor and, in the future, Smart Shelf (Shelf Antennas). • Readers that power and communicate with the tags for data capture and provide host connectivity for data migration. Tags Tags contain embedded chips that store information unique to the objects to which they are applied. Available in various shapes and sizes, tags, often called transponders, receive and respond to requests for their data. Tags require power to send data, and are available with two power options:
• Active Tags: typically powered by light-weight batteries and have limited life. • Passive Tags: powered by the reader’s RF field. Passive tags are much lighter, less expensive, and have a much longer life than active tags. Antennas Antennas transmit and receive radio frequency signals under the control of a reader. Antennas do not perform processing. A read point is the RF range of an antenna. Readers Readers are devices that provide a means for communicating with the tags and transferring their data to a host computer. Readers also provide features such as filtering, parity checks, and tag writing. The AR400 RFID Reader The Symbol AR400 is an intelligent, multi-protocol reader that provides real-time, seamless tag processing for all EPC-compliant tags: Class 0 (Read Only), Class 0 (Read/Write, also known as Class 0+), and Class 1 (Read/Write). Class 0 and Class 1 protocols are run in the Ultra-High Frequency range (~900MHz). Figure 1-2. AR400 Reader, Top and Side Views The AR400 provides a wide range of features that enable implementation of complete, high-performance, and intelligent RFID solutions. Multiple Connection Options The AR400 provides flexibility for connecting to networks via Ethernet or serial connection. Because each AR400 is identified by its unique IP address, it is accessible from anywhere on the network. The AR400 can also be configured to obtain its IP address from a DHCP server, automating the IP address and default Gateway configurations.
Flexible Read Point Configurations Connect up to eight antennas (four transmit and four receive) to a single AR400. This decreases the per-read-point cost. Logically combine antennas to create a single, “wide” read point with a much greater range than that of a single antenna. Configuration and Upgrading The AR400 is easy to reconfigure for an application via the Setup Wizard. The AR400 can also accept new firmware and configuration under host control. Tag Management Ad Hoc Querying Use ad hoc querying to send a query about tag visibility. The AR400 replies with either “Tag(s) Visible,” “Not Known” (never seen or imported), or “Not Visible” (previously seen but now missing, with last seen timestamp). Tag Filtering Use tag filtering to apply filters during read operations. A filter can include or exclude a tag based on the specified bit pattern. The AR400 offers two types of filtering: • Pre-Processing: The AR400 restricts its ability to read tags as directed by the include or exclude filtering specification. • Post Processing: The AR400 reads all tags it sees, and applies its filters before it reports these tags to the host computer. Tag List Use the tag list feature to send information about tags from the host to the reader. The host can purge the tag list to remove this information from the reader when it’s not needed. Event Management Event Notification Use event notification to receive notification about certain events. For example, receive immediate notification of a tag visibility change, or bundle all notifications and receive them later. Exception Notification and Heart Beat Notification The AR400 supports sending exception notifications via Simple Network Management Protocol (SNMP). The "heart beat" notification feature sends periodic messages that indicate whether or not the reader is functional.
Device Management Quick Backup and Recovery To back up and restore reader configuration, use any Web browser to download the configuration XML file, then download the file to the reader using the Administrator Console. SNMP Integration The AR400 can send real-time notification of specific events and failures to the SNMP server. Security Trusted Hosts The AR400 allows specifying the IP addresses of hosts that are allowed to connect to the reader. Use this security feature to prevent unauthorized network hosts from communicating with the reader. User Level Security The AR400 recognizes three access levels to assign to users: • View - view reader configuration settings. • Edit - view and edit configuration settings. • Maintenance - view and edit configuration settings, and perform administrative tasks such as updating reader firmware. Use this feature to assign different access levels to users, allowing them to perform necessary tasks without compromising security. Logging The AR400 keeps a log of all system-related activities for security and troubleshooting. Use the log, which includes time-stamped system activities such as good and bad tag reads, login attempts, hardware failures, and other events, to pinpoint problems to facilitate quick resolution, and to identify administrators who require additional training to prevent future problems. LEDs The AR400 LEDs indicate reader status as described in LED Indications . Table 1-1.

AR400 Parts Use only the parts provided with the AR400 reader or recommended by Symbol. Substituting other cables or parts can degrade system performance, damage the AR400, and/or void the warranty. Installing the AR400 Mounting Tips Consider the following before selecting a location for the AR400 reader: • Mount the AR400 indoors, in operating range, and out of direct sunlight, high moisture, or extreme temperatures. • Mount the AR400 in an area free from electromagnetic interference. Sources of interference include generators, pumps, converters, non-interruptible power supplies, AC switching relays, light dimmers, and computer CRT terminals. • Mount the AR400 within 15 feet of the antennas. • Ensure the AR400’s power cord can reach the power source outlet. • Mount the AR400 onto a permanent fixture, such as a wall or a shelf, where it won't be disturbed, bumped, or damaged. Allow a minimum of five inches of clearance on all sides of the AR400.
When installing the antenna, ensure a minimum separation distance of 9.1 in (23 cm) between the antenna and human beings.
Mounting the AR400 1. Position the AR400 on the wall or shelf, ensuring 5 inches (12.7 cm) of clearance on all sides. 2. Using the pre-drilled holes at the corners of the AR400 as a guide, drill four holes in the wall or shelf for mounting the AR400. 3. Secure the AR400 to the wall or shelf using four 1-inch long #10 screws. Connecting Antennas to the AR400 Power off the AR400 before connecting the antennas. Never disconnect the antennas while the AR400 is powered on or reading tags (when the yellow LED is lit). Doing so can damage the AR400. Do not turn on the antenna ports from a host to which antennas are not connected. 1. Attach the N-Male plug (large end) of an antenna connector cable to antenna 1. 2. Attach the DIN 1.0/2.3 jack connectors (small ends) of the cable to the TX1 and RX1 connectors on the AR400. 3. Secure the cable using wire ties. Do not bend the cable. Repeat these steps to connect antenna 2 to Tx2/Rx2, antenna 3 to TX3/RX3, and antenna 4to TX4/RX4. Portal Setup In portal situations such as dock doors, ensure the TX for an antenna on one side of the portal faces the TX of the opposing antenna. Similarly, ensure the antennas’ respective RXs face each other, as shown in Portal Alignment .Antenna Pair 1 Antenna Pair 2 Figure 2-2. Portal Alignment Powering the AR400 Connect the antennas before supplying power to the AR400.
To power on (and off) the AR400: 1. Connect the provided 24 VDC power supply to the AR400’s power port. 2. Plug the power supply into a 24 V power outlet. The green Power LED on the AR400 lights to indicate the AR400 is powered on. 3. To power off the AR400, unplug the power supply from the power outlet. The green Power LED turns off to indicate that the device is powered off and the system is not operational. Do not power off the AR400 until the yellow LED is off, indicating that reads are not in process. Verifying Hardware Functionality Power On Test The red Error LED lights when power is supplied to the AR400, then turns off. The green Power LED lights when the AR400 completes power-up and is operational. Read Test After the AR400 powers up, test the read range to verify that it meets requirements. 1. Enable polling using the Web-based AR400 Administrator Console. See Scan Control on page 3-6. 2. Control the AR400 through a real-time application such as TagVis. Refer to the TagVis User Guide. 3. Present a tag so it is facing the antenna. 4. Walk slowly toward the antenna until the AR400 lights the yellow Read LED to indicate that it detected and read the tag. The distance between the tag and the antenna is the approximate read range. For optimal read results, do not hold the tag at an angle or wave the tag, as this can cause the read distance to vary. Connecting the AR400 for Communication Connect the AR400 to a host or network via Ethernet or RS232.
Ethernet Connection The AR400 communicates to the host via a 10/100Base-T Ethernet cable and receives power via a Symbol AC power supply. Ethernet connection allows access to the AR400’s Administrator Console, used to change AR400 settings. To connect the AR400 via Ethernet: 1. Connect the RJ45 Ethernet cable to the 10/100Base-T Ethernet port on the AR400. See AR400 Parts . Ensure the Ethernet cable is terminated according to Table A-2 on page A-5. 2. Plug the other end of the Ethernet cable into the host system’s LAN port. If not connecting to an Ethernet network, connect one end of an Ethernet crossover cable (not provided) to the Ethernet card on the computer, and the other end to the TCP/IP port on the AR400. 3. On a networked computer, open an Internet browser and enter the IP address of the AR400 (the default IP address of the AR400 is 192.168.127.254). The Administrator Console login window appears. 4. Log in to the AR400 Administrator Console. If desired, change settings for the AR400, such as the IP address. See Chapter 3, Administrator Console. RS232 Connection Serial communication allows accessing the AR400’s Administrator Console using terminal software in order to change AR400 settings. Use this method of administration rather than the Web-based method in the following situations: • When the IP address of the AR400 is unknown. • When the AR400 obtains its IP address via DHCP but you need to know the IP address. • When crossover cables are not available and you need to change the IP address of the AR400 as per the network's addressing scheme. • Other situations when AR400 administration is necessary without connecting to the Web-based Administrator Console. • The Web-based Administrator Console is disabled. To connect the AR400 via RS232: 1. Connect a DB9 serial cable to the AR400’s RS232 port. See AR400 Parts. Ensure the cable is terminated according to Table A-3 on page A-5. 2. Plug the other end of the cable into the host computer. 3. On the host computer, launch a terminal emulation program (such as HyperTerminal) and configure it as follows: • Terminal Type: VT-100 • Port: COM 1-4 (depending on the COM port used) • Terminal Settings: • 38400 bps transfer rate • 8 data bits • no parity • 1 stop bit • no flow control
• no hardware compression 4. After establishing a connection with the AR400, type AdvancedReaderConsole on the host computer and press Enter. 5. Enter admin as the username and change as the password. These are the default settings. You cannot change the password from the serial console. To change the password (or create a new user account) use the Web-based Administrator Console. The host displays the Current Configuration menu: Current Configuration: Serial Number : redacted MAC Address : redacted 1 -- DHCP : OFF 2 -- IP Address : 192.168.127.254 3 -- IP Port : 3000 4 -- Network Mask : 255.255.255.0 5 -- Gateway : 192.168.1.1 6 -- HTTP Server is : ON 7 -- HTTP Port is : 80 8 -- RS485 Node Address : 4 9 -- Commit Change 10 -- Discard Change 11 -- Exit 12 -- Reboot 13 -- Show system log 14 -- Trace system log : OFF Select the menu number to change the item value: 6. To change a setting, enter the menu number, press Enter, then enter the new configuration value. For example, to change the IP address, enter 2 to select IP Address, then press Enter. Enter a new IP address value. 7. Enter 9, then press Enter, to apply the change.
Reading Tags To read tags while communicating with the host serially, connect the AR400’s RS-422/485 interface to a serial port on the host computer. Symbol provides an RS485-to-USB SeaLevel converter box and cable which connects the AR400 to the host's USB port for serial communication.

16. Click Scan Control to open the Scan Control window. This window indicates when the next periodic scan is scheduled. Figure 3-9. Reader Scan Control Window
Query Use the query feature to read tags and get their status information. The AR400 replies with one of the following tag status indications: • The tag is not known to the system. (The tag was never seen or imported.) • The tag is not visible to the system. (The tag is known to the system, but is currently not visible to any read point.) • The tag is visible at one or more read points. (A list of read points where the tag can be seen displays.) The tag ID and the type of the tag is required to query a tag. To obtain the tag ID and type of all tags the AR400 is reading: 1. Enable polling at the AR400 and configure read point classes as polled classes. 2. Open a new browser window and enter the following URL: http://[Reader IP Address] /cgi-bin/dataProxy?oper=queryTags XML containing the tag ID and type of all tags being read appears.Figure 3-10. Query Tags XML Window 3. Note the tag ID and type of the tag to query.
4. Open the Administrator Console and click Query.Figure 3-11. Tag Query Window 5. Enter the type and ID from Step 3 in the Type: and Id: fields. 6. Click Submit Query. The AR400 responds with the read point of the antenna that is reading the tag.
Writing a Tag Use the Write a Tag option to perform the following with a re-writable (R/W) tag: • Write, Erase and/or Lock Tag ID. • Write, Erase and/or Lock User Data. • Write / Lock kill code. • Kill A Tag To write a tag: 1. Click Write a Tag.Figure 3-12. Write an RFID Tag Window 2. Enter the ID to write on the tag in the Tag ID field. If the tag already contains an ID, select the Erase and Write checkboxes next to this field to overwrite it. To disable future changes of the tag ID select the Lock checkbox next to the Tag ID field. 3. Enter the data to write on the tag in the User Data field. If the tag already contains user data select the Erase and Write checkboxes next to this field to overwrite it. To disable future changes of the user data select the Lock checkbox next to this field. 4. To write a kill code, enter six hex digits in the Kill Code field. To lock the kill code select the Write and Lock checkboxes. 5. Select the antenna port to use for the write operation from the Read Point drop-down list. 6. Select whether to write information on a tag or kill a tag from the Action drop-down list.
Writing Tips Before writing to tags consider the following tips: • Locking a tag ID and/or user data prevents further erasing and writing the tag ID and user data on this tag. • After writing and locking the kill code, the kill code is required to kill the tag. • Killing a tag voids it for all read and write operations, rendering it useless for future operations.
Filtering The AR400 allows setting filters based on rules and then associating the filters with a specific read point. This prevents the AR400 from reporting specific tags. Filtering out tags involves the following steps: • Creating a filter rule • Creating a filter and associating it with the rule • Associating a filter to a read point class • Associating a read point class to an antenna. The following sections describe these processes. Creating a Filter Rule To create a filter rule: 1. Click Tag Selection.Figure 3-13. Tag Selection Filter Window
2. Click Create A New Rule. Figure 3-14. Tag Filter Rule Window 3. Choose the values for specific bits on which to base the filter. 4. Enter a name for the rule in the Filter Rule Name: field. 5. Select an option from the Test Method drop-down list. Inclusive indicates that all tags matching the rule are reported. Exclusive indicates that all tags matching the rule are not reported. 6. Click Add Tag Filter Rule to return to the Tag Selection Filter window. The new rule appears in the Tag Filter Rule List. 7. Enter a name for the filter in the Name: field.

See Committing / Discarding Changes.
Event Notification The AR400 reader provides notification when particular events occur. Select whether to receive event notifications, and select from three different types of events: • Visibility events • Threshold events • Network status events. The Event Notification window provides the following parameters: • Host Notification: Web-based notifications of events are sent to this link. Typically this is the URL of the Web server which is running an application which can trap and display these notifications. • Send SNMP Trap To: This is the IP address of the SNMP server to which to send event traps. Visibility Events These events occur when tag visibility changes. There are three types of visibility events: • New tag event: occurs every time the AR400 reads a new tag. • Tag not visible event: occurs when the system knows about the tag but the tag is no longer visible. • Visibility changed event: a generic event that occurs when the read point that read the tag changes. Threshold Event Threshold events occur when the number of visible tags drops below or rises above a threshold specified via a tag list notification reply. Network Status Event Network status events indicate a change in reader status, e.g., a problem with the AR400. The two types of network status events are Device and Program. Device events can indicate whether the status change is reported for the device or in association with a parent device. For example for a disabled AR400, the AR400 receives a 'user/disable' status notification, and the read point(s) associated with the AR400 receive a 'user/disable/parent' notification. Similarly, if a device fault occurs for the AR400, all corresponding events for the device fault also occur for each read point associated with that AR400. After correcting the fault, enabling the AR400 also enables 'parent disabled' devices associated with it. Exception Events Exception events provide the same type of information available via SNMP, but using XML. An exception event provides information when a device goes off-line, polling is turned off, etc. Select this option if there is no SNMP support, but you require notification if the device/program changes state.
Selecting Event Notification Options To select the event notifications to receive: 1. Select Notifications. Figure 3-25. Event Notifications Window 2. Click on the appropriate Notify option for each event type. Figure 3-26. Setting Notify Options
3. In the Notify Option: drop-down list, select one of the following options: • Never: do not provide notification for the event type. • Immediate: provide notification when the event occurs, provided the event is not filtered out. • Moderated: retest this condition every minute up to the timeout value. If the condition still exists and an intervening event has not occurred, provide notification for this event type, if the event is not filtered out 4. If you selected Moderated in the previous step, enter the timeout value in seconds in the Moderated Timeout (seconds): field. 5. Click Set Notify Option. 6. In the main Event Notifications window, click on the appropriate Filter By option for each event type. Figure 3-27. Setting Filter Options 7. Select the type of event filters. Options available are: • None: No filter. All events pass through. • Zone Inclusive: Only events that occur in a specific Read Point Zone pass through. • Class Inclusive: Only events that occur in a specific Read Point Class pass through. • Read Point Inclusive: Only events that occur in a specific Read Point pass through. • Zone Exclusive: Only events that do NOT occur in a specific Read Point Zone pass through. • Class Exclusive: Only events that do NOT occur in a specific Read Point Class pass through. • Read Point Exclusive: Only events that do NOT occur in a specific Read Point pass through. 8. Click Set Filter Option. 9. To receive event notifications, in the main Event Notifications window enter a valid link in the Host Notification Link: field, then click Set Host Link. If this is not set or is not valid, no notifications occur. 10. To receive network status event notifications, in the main Event Notifications window enter a valid link in the Send SNMP Trap To: field. 11. Click an SNMP Version: radio button to select the version of SNMP. 12. Click Set SNMP Configuration.
Committing / Discarding Changes To apply reader configuration modifications made using the Administrator Console, click Commit/Revert to save these changes and notify the AR400 to update its configuration file, which updates the AR400 configuration. While a successful update can take several seconds, the system continues to operate with only a one or two-second period where no polling occurs. To save changes when using the Administrator Console: 1. Click Commit/Revert.Figure 3-28. Commit/Revert Window 2.

Setting Date and Time To set the reader’s date and time: 1. Click Maintenance in the main Administrator Console window. 2. Click Date/Time. Figure 4-2. System Time Management Window 3. To synchronize the reader’s clock with a particular SNTP server, enter the server’s address in the SNTP Server Address: field and click Set SNTP Parameters. To set the reader’s system time manually, use the drop-down lists to select units of time, then click Set Date and Time. SNTP (Simple Network Time Protocol) is an Internet standard protocol (built on TCP/IP) that assures accurate synchronization to the millisecond of computer clock times in a network of computers.
Getting Firmware Version Number The Version Control window displays the current firmware version and allows upgrading to new firmware. To view this window, click Version. Figure 4-3. Version Control Window See Version Control Fields for descriptions of fields. Table 4-2. Version Control Fields Access Level Setting Description Radio Frequency Regulation Region Select a Radio Frequency Regulation region for the AR400. Image The current image is marked Active. This is the active firmware version the reader is running. Type This indicates the type of image saved in that buffer. ARM indicates firmware for the main processor. Other image types can appear for troubleshooting or maintenance purposes. Version Displays the version number of the image in the format "major number.minor number.build number". Create Time Indicates the image release date.
Load Time Indicates when the image was loaded into the reader. Source Indicates the channel from which this image is loaded.
Updating Firmware Before downloading the latest firmware from the Symbol FTP Website, perform the following: • Obtain a valid Default Gateway for the reader, and ensure the reader can access the Internet. • Use the Ping Command against the URL ftp2.matrics.com and note the IP address of the server which contains the firmware. To download the firmware from the Symbol Web site: 1. Click Maintenance from the main menu. 2. Click Version. See Version Control Window for the Version Control window. 3. In the FTP Link field, enter the following IP address: ftp://transport.symbol.com followed by /image_file_name. 4. In the FTP User Name field, enter customer 5. In the FTP Password field, enter gen2ldr05 6. Click Download New Firmware. The AR400 updates the image and reboots. Download the FPGA image first if both this image and a firmware image are available. The FPGA does not reboot the AR400; if only updating the FPGA image, reboot the reader after the update. Refer to the log before rebooting to ensure the update was successful. Monitoring Logs Network administrators can use logs for auditing and troubleshooting the AR400. AR400 supports two types of logs: • System Log - includes the log information generated by the reader's internal instructions. This is a circular queue which can hold a maximum of 200 records. • Access History - provides a history log for access to this reader. This log records every successful access to the reader through the Web interface. This is also a circular queue which can hold a maximum of 20 records.
Backing Up the Configuration The reader supports the following backup configuration functions: • Rolling back maintenance errors and restoring the reader to a particular date and time. • Pushing reader-specific changes made to the config.xml file to multiple readers, simplifying multi-reader management. • General configuration backup that can be restored when required, such as hardware replacement. To back up the reader's configuration: 1. Open the browser and enter the URL http://[Reader IP address]/Config.xml. For example, if the reader’s IP address is 123.123.123.123, enter: http://123.123.123.123/Config.xml An XML file similar to the following appears, depicting the current reader configuration.Figure 4-4. Sample Reader Configuration XML File 2. Save the XML file with a naming / date convention that facilitates recognizing the reader and the date of the backup. Most browsers allow saving XML files to the hard disk. In Internet Explorer, select File - Save As… 3. Click Save and use Windows Explorer to verify that the file is saved correctly.
Restoring a Configuration The restore feature restores a backed-up configuration file to enable quick configuration parameter recovery. This section describes how to restore the backup file on the reader from which it was backed up. For restoring a reader’s backup to another reader, see Restoring Backup Across Readers. Config.xml contains reader-specific configuration parameters such as IP address and port number. To push the same configuration file to multiple readers, make multiple copies of the configuration file and change these reader-specific parameters for each reader in each configuration file using text editing software such as Notepad, before pushing each configuration file to the appropriate reader. To restore backup on the reader from which it was taken and replace non-functional readers with new ones: 1. Copy the backup XML file from the backup folder to a temporary folder on the host PC, and rename the file Config.xml. 2. Load the backup XML file onto an FTP server. If the network connected to the reader has an FTP server, upload the XML file to this server. Consult the administrator for assistance with uploading files onto the FTP server. 3. Connect to the reader using the Web-based Administrator Console. Click Maintenance from the main menu, then Version. Figure 4-5. Version Control Window
4. In the FTP Link field, enter the FTP URL of the server. 5. Enter the username of a user account on the server in the FTP User Name field. 6. Enter the password in the FTP Password field. 7. Click Download New Firmware. A message indicates the XML file is loading. After several minutes, refer to the FTP server log to confirm the download was successful. Backup / Restore Example Following is an example of backing up and restoring a reader’s configuration: 1. Configure the reader. See Reader Maintenance - Changing Communication Settings . The following window shows a sample Reader Configuration window for the reader, which includes the configuration of various read points.Figure 4-6. Sample Reader Configuration Window 2. Backup the configuration file. See Backing Up the Configuration . The following window shows the Config.xml file for this reader, saved to the hard disk, then uploaded to the FTP
server.Figure 4-7. Sample Config.xml File 3. Restore the backup Config.xml file. See Restoring a Configuration . The Administrator Console indicates that the reader successfully restored the previous configuration. Logging Out from the Console Before closing the browser, log out of the console. Click Logout from either the maintenance menu or the main menu. If you forget to log out or leave your browser idle, the session automatically logs out.

You changed the node address, IP address, or other reader configuration parameter(s) using the Administrator Console, and the application expects the previous configuration. Update the settings within the application. Refer to the application’s manual. Polling is enabled. Some real-time applications require disabling polling. Refer to the application’s manual, and if required, disable polling using the Scan Control feature of the Administrator Console. See Scan Control on page 3-6. Certain real-time applications are no longer functional. The user closed the browser without logging out of the Administrator Console, so other applications cannot connect to the reader. Log out of the Administrator Console.
If problems still occur, contact the distributor or call the local Symbol Support Center. See page x for the telephone numbers.

It is driven through an external 6 dB pad to add stability. Once the gain has been tested and set, the driving source, the Symbol Technologies Inc. AR400 output is set to a level, which results in less then the FCC limit of 30 Watts ERP field strength from the antenna at the frequency of highest gain from the amplifier.
