RFID SystemsBrady Wand Users Guide Copy write 1998,WH Brady2000-0001 5IntroductionBrady RF/ID systems consist of Brady RF/ID tags and a reader/writer for reading data from tagsor writing data to tags. Several different types tags and various reader options are available tosuite any application.Brady RF/ID TagsBrady RF/ID tags consist of a microchip, coil antenna, and packaging. Packaging and microchipoptions can be combined to fit any RF/ID tag requirement.Microchip options include read only, read write and several different memory capacities forread/write applications. Typically, read only tags are randomly preprogrammed with 40 bits(10HEX Characters) of permanent data. Versions of read only tags are available which can beprogrammed once with a designated number. This number is then permanently stored in the tagand can be read many times. This type of tag is typically referred to as a WORM (write once readmany).Read/write tags have permanent data as well as programmable data. The permanent data issimilar to a read only tag. It is usually 32 bits (8 HEX Characters) of data which can not bechanged. Read/write tags also have memory which can be changed. The amount of changeablememory in a read/write tag ranges from 152 bits (19 Alphanumeric Characters) to 1536 bits (192Alphanumeric Characters). Versions of read/write tags are also available with passwordprotection or data encryption for high security applications that require secure data transmissionbetween the reader and the tag.Packaging options include a variety of forms as well as different case materials for a wide rangeof operating temperatures and chemical resistance.Brady WandThe Brady Wand is an RF/ID reader which interfaces to a host PC or hand held data collectiondevice through standard RS-232/422/485 or Wand emulation hardware format. The reader istypically powered from the host device with 5V D/C. If an un-powered data port is used, anexternal battery source must be provided to power the reader.The Brady Wand was designed to be used in various Industrial applications which require ruggedand reliable equipment. Versions of the Wand are available with an Intrinsically Safe Ratingwhich allow them to be used in explosion hazard areas. The Wand is water resistant and canwithstand many of the harsh chemicals found in industrial manufacturing and petrochemicalprocessing. In environments where visual and audible indicators can not be heard or seen, theBrady Wand has a unique vibrating feature for indicating reader status to the operator.
RFID SystemsBrady Wand Users Guide Copy write 1998,WH Brady2000-0001 6UseOperating the Brady Wand is very easy. To read/write to a tag the operator presses the largeactivation button located above the hand grip.(see fig.1). Once the button is pressed, the readerelectronics sends out a radio frequency field to search for a tag. During this time the red LED,located above the button, will illuminate indicating that the Wand is in search mode. When a tagis present within the field of the reader antenna, the microchip inside the tag is activated andtransmits its ID code back to the reader. . If the data received from a tag is valid, the green LEDlocated above the activation button will illuminate, an audible “beep” will sound, and the wandwill vibrate for a short period of time.After the reader receives the transmission from the tag, it converts this information RS-232/422/485 or Wand emulation format and transmits the data to the host.The Brady Wand can also be used remotely without pressing the button. When used for remoteread/write operation, commands which activate the reader/writer are sent from the host to theWand without the need for pressing a button. (See Programmers Guide for information on hostcommands).

Follow the instructions carefully. Any deviation from these instructions may void theLimited Hardware Warranty.Upon Receipt Remove items from shipping the container. Check package contents for the following items:1. Brady Wand Reader/Writer2. Coil cable with circular connector and flying leads.3. Optional accessories. Fill out and return product registration card.Connecting the Brady Wand to a Data Collection DeviceThe coil cable is used for connecting the Brady Wand reader/writer to a host computer or datacollection device. (See Fig 2 and 3 page 7 ) Because of the many different data collection devicesand serial port formats which can be used, consult the owners manual of the data collectiondevice to be used for proper wiring and connector information. See wiring diagrams on page8,9,10,11 for detailed wiring and connector pin-out information about the Brady Wand.Once you have determined the proper wiring and connector information for the data collectiondevice, the cable can be plugged into the Brady Wand.*Connectors are available at the time of purchase to match to most common data collectiondevices.If you are interfacing to a data collection device which does not provide power through the serialport, you must use the optional external power interface box. This box is connected between thedata collection device’s serial port and the Brady Wand’s serial port. The external powerinterface box provides battery power from one 9V battery. (See fig 3 page 7).

RFID SystemsBrady Wand Users Guide Copy write 1998,WH Brady2000-0001 16Wand OperationOperating HintsBecause the Brady RF/ID System uses radio frequency (RF) energy to communicate between thetag and the Wand, there are several important points to keep in mind while setting up andoperating the system. Metal effects both Wand and tag antennas by reducing the read range of the overall system. Ifat all possible, keep tags and the Wand antenna away from metal. Interference from other electronic sources can reduce read range. If the interference is strongenough, it may render the system inoperative. When reading tags, keep the Wand and tags as faraway from these sources as possible. These sources include but are not limited to:1. CRTs (Computer Monitor, CCTV Monitor TV’s)2. Light Dimmers3. Brush-type motorsOperating the WandTo read or write to a RF/ID tag:1. Bring the nose of the wand to within 1 inch of the tag to be read. Although the Wand willread/write from any angle, best results are achieved when the nose of the Wand is parallel to theface of the tag. Read range will also vary with the type of tag to be read and the operatingenvironment2. Press the button located above the handle.3. The red LED will illuminate and stay on for approximately 5 seconds or until a valid tag hasbeen detected. Whenever the red LED is on, it is an indication that the Wand is activelysearching for a tag.4. Once the Wand detects a valid tag signal, the green LED will illuminate momentarily, the audioindicator will sound a short beep and slight vibrating sensation will be felt.5. Release the button when the green LED illuminates. This will speed the process of readingsubsequent tags.6. Once a valid tag has been read, the wand then converts the data received from the tag into therequired serial data format (RS-232,485,Barcode) and sends this information on to the host ordata collection device.Remote OperationThe Brady Wand can be used remotely used from the operator. The above procedure applies forremote operation but instead of pressing the button to read or write to a tag, a command is sentfrom the host data collection device to the wand. See the Wand Programmers Manual for moreinformation on remote operation.
