Introduction
Brady RF/ID systems consist of Brady RF/ID tags and a reader/writer for reading data from tags
or writing data to tags. 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 Medium Range Reader
The Brady Medium Range Reader is an RF/ID reader which interfaces to a host PC or other data
collection device through standard RS-232/422/485 or Wand emulation hardware format.
The Brady Medium Range Reader was designed to be used in various Industrial applications
which require rugged and reliable equipment. Versions of the Medium Range Reader are available
with an Intrinsically Safe Rating which allow them to be used in explosion hazard areas. The
Medium Range Reader is water resistant and can withstand many of the harsh chemicals found in
industrial manufacturing and petrochemical processing.

Setup and Wiring
The following is a simple procedure for setting up and operating the Brady Medium Range
Reader/writer. Follow the instructions carefully. Any deviation from these instructions may void
the Limited Hardware Warranty.
Upon Receipt
Ÿ Remove items from shipping the container.
Ÿ Check package contents for the following items:
1. Brady Medium Range Reader Reader/Writer
2.Optional accessories.
Ÿ Fill out and return product registration card.
Brady Medium Range Reader Power Supply Requirements
The Brady Medium Range Reader needs to be powered from a 12V D/C, 500mA Linear Power
Supply. Using a Switch Mode or similar supply may degrade reader performance or render it
inoperable.
Connecting the Brady Medium Range Reader to a Data Collection Device
The permanently attached cable is used for connecting the Brady Medium Range Reader
reader/writer to a host computer or data collection device. (See Fig 1 page 6 ) 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.
Once you have determined the proper wiring and connector information for the data collection
device, the cable can be connected to the Brady Medium Range Reader cable.
Proper splicing techniques should be used when adding additional cable to the Brady Reader
cable.

Medium Range Reader Operation
Operating Hints
Because the Brady RF/ID System uses radio frequency (RF) energy to communicate between the
tag and the Medium Range Reader, there checking this several important points to keep in mind
while setting up and operating the system.
Ÿ Metal effects both Medium Range Reader and tag antennas by reducing the read range of the
overall system. If at all possible, keep tags and the Medium Range Reader antenna away from
metal.
Ÿ 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 Medium Range
Reader 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 Medium Range Reader
Operation of the Brady Medium Range Reader is accomplished remotely by sending a series of
commands from the host computer. To read/write to a tag the host sends a series of commands to
the reader over the serial communication line. The reader will initiate these commands and
responds back to the host with the status of these commands and information gathered from tags.
See the software programmers manual for further details on reader commands.
