The Alien ALR-H450 comes with world-wide band WCDMA technology. Multi-channel data and voice communication guarantees real-time communication and data efficiency. Precautions When Using the Battery Dont leave batteries unused for extended periods of time, either in the product or in storage. When the battery has been unused for 6 months, check the charge status and charge or dispose of the battery as appropriate. The typical estimated life of a Lithium-Ion battery is about two or three years, or 300 to 500 charge cycles, whichever occurs first. One charge cycle is a period of use from fully charged, to fully discharged, and fully recharged again. Expect a two to three year life expectancy for batteries that do not run through complete charge cycles. Rechargeable Lithium-Ion batteries have a limited life and will gradually lose their capacity to hold a charge. This loss of capacity (aging) is irreversible. As the battery loses capacity, the length of time it will power the product (run time) decreases. Lithium-Ion batteries continue to slowly discharge (self-discharge) when not in use or while in storage. Routinely check the batterys charge status. Observe and note the run time that a new fully-charged battery provides for powering your product. Use the new battery run time as a basis to compare run times for older ALR-H450 USER GUIDE DOC. CONTROL #8102146-000 REV C 1 INTRODUCTION CHAPTER 1 batteries. The run time of your battery will vary depending on the products configuration and the applications that you run. Routinely check the batterys charge status. Carefully monitor batteries that are approaching the end of their estimated life. Consider replacing the battery with a new one if you note either of the following conditions:
The battery run time drops below about 80% of the original run time. The battery charge time increases significantly. If a battery is stored or otherwise unused for an extended period, be sure to follow the storage instructions in this document. If you do not follow the instructions, and the battery has no charge remaining when you check it, consider it to be damaged. Do not attempt to recharge it or to use it. Replace it with a new battery. Always follow the charging instructions provided with your product. Refer to your products user manual and/or online help for detailed information about charging its battery. Charge or discharge the battery to approximately 50% of capacity before storage. Charge the battery to approximately 50% of capacity at least once every six months. Remove the battery and store it separately from the product. Store the battery at temperatures between 5 C and 20 C (41 F and 68 F). Precautions When Using the Handheld Careless use or repair attempts may damage the unit or stored data and will void any warranties. Alien is not responsible for this damage, so important data should be kept separately. If you have a problem, do not try to repair or disassemble the product yourself; please contact Alien customer service. Do not use where devices sensitive to electromagnetic radiation are operating, such as a hospital, airplane, etc., or risk of interference may occur. The unit may malfunction at very high or low temperatures, or in a very humid environment. Please do not use sharp objects to touch the screen, or damage may result. Use only soft objects, like your finger or the included stylus, on the touchscreen. NOTE The main battery comes preinstalled into the handheld. Make sure to remove protective film from the battery terminals before operating the unit. ALR-H450 USER GUIDE DOC.

CONTROL #8102146-000 REV C 11 RFID TAG READER Inventory Utility CHAPTER 3 The Inventory utility allows you to scan all of the tags within range of the reader, and see each tags EPC and read count in a scrollable list. You start and stop the inventory utility by either holding the pistol-grip trigger button, or by clicking once on the green Start button. The reader continues to read tags until you release the trigger or click the Stop button. Click the OK button at the bottom-right corner to return to the main screen. Clicking the Mask button at the top of the Inventory screen takes you to a page where you can specify a subset of tags to read (see the Tag Mask section). This powerful feature causes the reader to only read the tags you want it to read those selected by the mask. Each tag that is read is added to the scrolling list, along with the count for each tag. The number of unique tags and total number of reads is displayed. You can clear and save the list with the buttons above the list. Geiger Tag Utility The Geiger Tag utility is designed to assist you in finding the location of a particular tag, or one of a group of tags. It does this by measuring the returning signal strength (RSSI) from the tag, and displaying this information on the screen, along with an audible and vibratory queue. As you pass the reader near a tag, the RSSI increases, and you will see and hear the change. To start the Geiger Tag search, either hold the pistol-grip trigger button, or click once on the green Start Search button. The reader continues to read tags until you release the trigger or click the Stop button. Click the red Close box at the top-right corner to return to the main screen. ALR-H450 USER GUIDE DOC. CONTROL #8102146-000 REV C 12 CHAPTER 3 RFID TAG READER The Geiger will show the tags signal strength. Use the Start Search button (or pistol-grip trigger) to start the search. Use the Mask button to refine your search to specific tags. When a tag is read, its EPC is displayed on the screen, along with graphical and numeric readouts of the tags return signal strength. Tag Access Utility The Tag Access utility allows you to read from and write to specific portions of a tags memory. The utility is divided up into two separate tabs: the Basic tab and the Advanced tab. The Basic tab gives a quick overview of the tags memory layout, and gives you basic ability to write new data to the tag. The Advanced tab gives full access (bank, start pointer, and length) over the low-level writing and reading operations, as well as controls for locking and unlocking specific portions of tag memory. EPC Gen2 tag memory is divided up into four distinct banks: Reserved, EPC, TID, and User. The Reserved bank contains the tags Access password and Kill password (each two words long), though all tags may not support both passwords. The EPC bank contains the tags id its Electronic Product Code (or EPC) along with some other information related to the EPC. The TID bank is read-only, and contains information about the tags manufacturer, model, and basic capabilities. Alien Higgs tags contain bits in the TID bank that are guaranteed to be unique from one tag to the next. The User bank may not be present in all tag types, and when present, each tag provides different amounts of available user memory. Basic Access Tab The Basic Access tab has text fields for each of the separate fields of tag memory. Clicking the Read button (or pulling the pistol-grip trigger) causes the reader to try and read all of the data for each of the fields, from whatever tag is in the field. The separate fields fill in, one-by-one, as the data is read. Since there is no definitive way of knowing how much User memory a tag has, the reader simply reads the User data two words (32 bits) at a time, until a failure occurs. ALR-H450 USER GUIDE DOC. CONTROL #8102146-000 REV C 13 CHAPTER 3 RFID TAG READER The Basic Access tab gives a visual overview of all of the fields in tag memory. Pressing the Read button (or pulling the pistol-grip trigger) fills in each memory field with data from the tag. Pressing one of the small refresh buttons labeling each memory field will cause the reader to only read data from that field. Pressing one of the pencil write buttons causes the reader to write the shown data to the tag. You can edit the data in the field before writing it to the tag. The field turns turns white or red, depending on the success of the write operation. 14 ALR-H450 USER GUIDE DOC. CONTROL #8102146-000 REV C CHAPTER 3 RFID TAG READER When there are many tags in the field, the Basic Access tab can have difficulty reading all of the data from the same tag when you click the Read All button. To make sure that you are accessing the same tag throughout the operation, you should set a tag mask, using the blue Mask button at the top-left corner of the screen. Also, when the tag has some of its memory fields locked with an access password, you must provide that same password as part of the access operation in order for it to succeed. You use the violet APwd field at the top-right corner to do this. The Mask button lets you restrict the reader to only access one tag at a time. The APwd field is where you can enter in an Access Password, for accessing tag memory that may have been locked. ALR-H450 USER GUIDE DOC. CONTROL #8102146-000 REV C 15 RFID TAG READER CHAPTER 3 Advanced Access Tab The Advanced Access tab has three general control areas: Read, Write, and Lock. All three operations require you to specify the bank of tag memory to access (Reserved, EPC, TID, and User). When reading and writing, you must specify the offset into that bank of memory where you would like to access. The reading operation also requires you to specify the length of the data to read. Both the offset and length parameters are measured in words (1 word = 2 bytes = 16 bits). Three operations s in Advanced Access:
Read, Write, and Lock. Each requires you to specify a memory bank. To read from a memory bank, select the Bank, start Word Pointer, and Word Count, then click the read/refresh button. Note that the tags EPC starts at word #2 of the EPC bank. To write data to a memory bank, select the start Word Pointer to write to, and enter the hex-formatted data, then click the pencil/write button. 16 ALR-H450 USER GUIDE DOC. CONTROL #8102146-000 REV C CHAPTER 3 RFID TAG READER When locking, you have the option of locking the Access Password and Kill Password (both in the Reserved bank) separately, so the Lock command has a list of tag memory fields instead of banks. The other parameter is the type of lock: Lock, Unlock, PermaLock, and PermaUnlock. All locking operations require you to confirm by clicking OK to an alert message. The Perma options are, well, permanent, so use caution. Locking a field doesnt immediately protect it until you also write a non-zero Access Password to the tag (and you should probably lock that field as well!). Please refer to the EPC Gen2 Protocol Specification for complete details on how the various locking operations affect the tags behavior. Just like on the Basic Access screen, you have full access to the tag Mask and current Access Password in this screen. When locking, specify the field to lock, the lock type, then click the Lock button. You will be given a chance to change your mind before performing a lock operation. Tag Mask When the application first launches, it is configured to look for and report every tag it sees. You dont always want to read every tag perhaps you are searching for only one class of product, or are trying to access one particular tag in order to write data to it. The Gen 2 protocol provides for something called a select mask - a filter definition that is broadcast to all of the tags in the field before each operation, that specifies which tags are allowed to participate in that operation. The ALR-H450 allows you to specify a tag mask, which is used transparently in each of the utility screens. The current mask is displayed at the top of each screen near the Mask button. Each utility has its own mask, so use caution when switching from the Inventory to the Geiger to the Tag Access screens. At its heart, a tag mask defines a piece of data that must match exactly a specific portion of the tags memory. This includes the memory bank (not just the EPC bank), a pointer offset into that bank, and the actual hex data to match against. In reality, you dont always want to have to think about memory banks and pointer offsets you just want to find that pair of jeans that is on the wrong rack, or you only care about pallet tags, ALR-H450 USER GUIDE DOC. CONTROL #8102146-000 REV C 17 RFID TAG READER CHAPTER 3 however that is defined for you. The Tag Mask screen therefore gives you four ways to pick a tag mask:
1. Scanning the field for tags (or loading a text file of EPCs) and picking a tag from a list. 2. Exactly defining the bank, offset, and hex data. 3. Picking a named mask from a preset list 4. Selecting a pre-defined asset (RFID+barcode+picture) Once you have defined and set your mask, just close the Tag Mask window and your new mask will be displayed at the top of the screen you were originally on, and it will be used in subsequent operations. Tag Mask Scan The Scan tab acts just like the Inventory screen start/stop the reader with the trigger or Scan button, and all tags in range are displayed. 18 After scanning. select a tag from the list and click the Set button. To clear the mask, click the Clear button. ALR-H450 USER GUIDE DOC. CONTROL #8102146-000 REV C CHAPTER 3 RFID TAG READER Tag Mask Custom The Tag Mask Custom tab allows you to define an arbitrary mask on any portion of a tags memory, or a simpler EPC Prefix mask. The middle section is where you actually define your mask. There are two options here: create a mask based on an EPC prefix (i.e. all tags starting with), or create an arbitrary custom mask. If you select EPC Starts With, the only thing you have to provide is the hex data representing the initial part of the EPC code for your tags (the other controls are disabled). If you select Custom, you choose the bank and pointer offset, along with the mask data. Click the Set button to define your mask. Defining a mask based on an EPC prefix is easy just click the EPC Starts With radio button, enter the EPC data and click the Set button. Defining a custom mask requires you to specify the bank, bit offset, and bit length of the mask, along with the data. ALR-H450 USER GUIDE DOC. CONTROL #8102146-000 REV C 19 RFID TAG READER CHAPTER 3 Tag Mask Presets The third way to set a tag mask is with the Presets tab. This screen can show a list of pre-defined tag masks, such as all tags, all Higgs3 tags, etc. Youll need to create a list of your own, and then load it into the app. To use your own list of mask presets, just create a text file that you can access with the Load button. Each line of the mask presets file should contain the bank number, bit pointer, but length, mask data, and an optional preset name all separated by commas. For instance, a presets.txt file might look like this:

By linking those pieces of information, you can cross-reference a barcode scan with the EPC code on that products RFID tag, and see a picture of the asset each time the tag is read. If you need to search for a particular asset, you can select it from the list of assets, set the Tag Mask to that assets EPC code, and then use the Geiger utility to go look for that tag. When the tag is detected, the items picture is shown on the screen for verification, and you can also see the associated barcode as well. To create a new asset, click the + button. To remove or edit an existing asset, select it from the list and then click the - or pencil/edit buttons. At the Assets mask screen, simply select one of the created assets from the list and then click the Set button to mask on that asset. There are four steps to creating or editing an asset, and pulling the gun trigger performs each one and advances you to the next step.
