Several different types tags and various reader options are available to suite any application. Brady RF/ID Tags Brady RF/ID tags consist of a microchip, coil antenna, and packaging. Packaging and microchip options can be combined to fit any RF/ID tag requirement. Microchip options include read only, read write and several different memory capacities for read/write applications. Typically, read only tags are randomly preprogrammed with 40 bits(10 HEX Characters) of permanent data. Versions of read only tags are available which can be programmed once with a designated number. This number is then permanently stored in the tag and can be read many times. This type of tag is typically referred to as a WORM (write once read many). Read/write tags have permanent data as well as programmable data. The permanent data is similar to a read only tag. It is usually 32 bits (8 HEX Characters) of data which can not be changed. Read/write tags also have memory which can be changed. The amount of changeable memory in a read/write tag ranges from 152 bits (19 Alphanumeric Characters) to 1536 bits (192 Alphanumeric Characters). Versions of read/write tags are also available with password protection or data encryption for high security applications that require secure data transmission between the reader and the tag. Packaging options include a variety of forms as well as different case materials for a wide range of operating temperatures and chemical resistance. Brady Wand The Brady Wand is an RF/ID reader which interfaces to a host PC or hand held data collection device through standard RS-232/422/485 or Wand emulation hardware format. The reader is typically powered from the host device with 5V D/C. If an un-powered data port is used, an external battery source must be provided to power the reader. The Brady Wand was designed to be used in various Industrial applications which require rugged and reliable equipment. Versions of the Wand are available with an Intrinsically Safe Rating which allow them to be used in explosion hazard areas. The Wand is water resistant and can withstand many of the harsh chemicals found in industrial manufacturing and petrochemical processing. In environments where visual and audible indicators can not be heard or seen, the Brady Wand has a unique vibrating feature for indicating reader status to the operator. Brady Wand Users Guide 2000-0001 Copy write 1998,WH Brady RFID Systems Use Operating the Brady Wand is very easy. To read/write to a tag the operator presses the large activation button located above the hand grip.(see fig.1). Once the button is pressed, the reader electronics 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 tag is present within the field of the reader antenna, the microchip inside the tag is activated and transmits its ID code back to the reader. . If the data received from a tag is valid, the green LED located above the activation button will illuminate, an audible “beep” will sound, and the wand will vibrate for a short period of time. After the reader receives the transmission from the tag, it converts this information RS232/422/485 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 remote read/write operation, commands which activate the reader/writer are sent from the host to the Wand without the need for pressing a button. (See Programmers Guide for information on host commands). Brady Wand Users Guide 2000-0001 Copy write 1998,WH Brady RFID Systems Brady Wand Users Guide 2000-0001 Copy write 1998,WH Brady RFID Systems Setup and Wiring The following is a simple procedure for setting up and operating the Brady Wand RF/ID read/writer. Follow the instructions carefully. Any deviation from these instructions may void the Limited Hardware Warranty. Upon Receipt Remove items from shipping the container. Check package contents for the following items: 1. Brady Wand Reader/Writer 2.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 Device The coil cable is used for connecting the Brady Wand reader/writer to a host computer or data collection device. (See Fig 2 and 3 page 7 ) Because of the many different data collection devices and serial port formats which can be used, consult the owners manual of the data collection device to be used for proper wiring and connector information. See wiring diagrams on page 8,9,10,11 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 collection device, the cable can be plugged into the Brady Wand. *Connectors are available at the time of purchase to match to most common data collection devices. If you are interfacing to a data collection device which does not provide power through the serial port, you must use the optional external power interface box. This box is connected between the data collection device’s serial port and the Brady Wand’s serial port. The external power interface box provides battery power from one 9V battery. (See fig 3 page 7).

Metal effects both Wand and tag antennas by reducing the read range of the overall system. If at all possible, keep tags and the Wand antenna away from metal. Interference from other electronic sources can reduce read range. If the interference is strong enough, it may render the system inoperative. When reading tags, keep the Wand and tags as far away from these sources as possible. These sources include but are not limited to: 1. CRTs (Computer Monitor, CCTV Monitor TV’s) 2. Light Dimmers 3. Brush-type motors Operating the Wand To 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 will read/write from any angle, best results are achieved when the nose of the Wand is parallel to the face of the tag. Read range will also vary with the type of tag to be read and the operating environment 2.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 has been detected. Whenever the red LED is on, it is an indication that the Wand is actively searching for a tag. 4.Once the Wand detects a valid tag signal, the green LED will illuminate momentarily, the audio indicator 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 reading subsequent tags. 6.Once a valid tag has been read, the wand then converts the data received from the tag into the required serial data format (RS-232,485,Barcode) and sends this information on to the host or data collection device. Remote Operation The Brady Wand can be used remotely used from the operator. The above procedure applies for remote operation but instead of pressing the button to read or write to a tag, a command is sent from the host data collection device to the wand. See the Wand Programmers Manual for more information on remote operation.
