Chapter 1 ● Getting Started
This chapter contains an introduction to Escort Memory Systems and includes
general information relating to the HF-0405 RFID Controller and common uses for
RFID technology.
Introduction
Welcome to the HF-0405 Series RFID Controller Operator’s Guide. This guide will
assist you in the installation, configuration and operation of Escort Memory Systems’
HF-0405 Series RFID Controllers.
The HF-0405 Series is a complete line of passive high frequency read/write Radio-
Frequency Identification solutions. They are designed to be compact, reliable and
rugged, and though they measure only 56mm x 40mm, the HF-0405 RFID
Controllers are highly integrated with everything you will need to start benefiting from
RFID technology.
Our Background
Since 1985, Escort Memory
Systems has been an industry
leader in providing Radio
Frequency Identification (RFID)
devices and has built a solid
reputation by consistently
delivering an extended selection
of quality, durable industrial RFID
systems.
Today, Escort Memory Systems
continues to deliver a complete
line of high performance,
industrial RFID equipment,
including the HF-0405 Series RFID Controller.
The HF-0405 RFID Controller
Escort Memory Systems' HF-0405 Series RFID
Controllers are the latest in our line of passive RFID
controllers that utilize the Radio Frequency (RF) field
from the controller’s integrated antenna to power RFID
enabled tags. By being able to receive power from the
RFID controller, the tag, itself, does not need a battery
and is said to be “passive”.
Passive tags must enter the antenna’s electromagnetic
field to establish a radio link which allows for the transfer
of information through inductive coupling. The HF-
0405 uses the internationally recognized ISM frequency
![](/img.php?id=514280&img=bg9.png)
Chapter 1: Getting Started
10
of 13.56 MHZ to power the tag and then modulates side-band frequencies to
communicate.
The HF-0405 system provides cost effective RFID data collection and
control solutions to shop floor, item-level tracking, and material
handling applications.
The entire RFID system works by attaching a tag (or
transponder) to a product or its carrier which acts as an
electronic identifier, portable job sheet, or real-time tracking
database. Tags are identified, read and written to by issuing
specific commands to the HF-0405 RFID Controller from the
Host.
Tags can be read and/or written to (which is sometimes referred
to as “interrogating the tag”) through any nonconductive, non-metallic
material, while moving or standing still, in or out of the direct line of sight.
The HF-0405 series RFID Controller is compatible with all LRP and HMS Series tags
from Escort Memory Systems. The HF-0405 can also
communicate with ISO 14443 and ISO 15693 tags
from other manufacturers.
Escort Memory Systems uses error checking routines
that ensure that the RFID controller receives tag data
correctly even in environments with heavy RF
interference. LED indicators on the RFID controller
provide continuous real-time feedback on the status of
the unit. (See Chapter 5, for more information
regarding LED status).

RFID Strategy & Case Studies
RFID Strategy is a term given to describe the manner or rationale in which a
company utilizes RFID communications to achieve quality, accountability, profit
and/or other business goals.
Strategies for RFID Implementation
• Read-Only Strategy
• Pass/Fail Strategy
• Standard Read/Write Strategy
• Mixed Read Only / Read/Write Strategy
• Your Own Unique Strategy
RFID Application Case Studies
The following case studies are taken from real-world RFID applications our
customers have put to good use.
In one proven configuration, a company applies disposable RFID labels to their
products during manufacturing and then tracks them, via RFID, throughout the entire
distribution channel. From manufacturing through retail and out to customers, the
complete supply chain history is stored directly within the product. In essence, this
method of using RFID labels creates "smart products"
that can communicate with their surrounding
environment.
RFID Helps Get Your Motor Running
An ingenious example of using RFID to create an
electronic manifest belongs to an automobile maker
that was looking for ways to improve and streamline their
engine manufacturing procedures.
Initially, an RFID tag containing routing and build
instructions is attached to an engine carrier. As the engine
and carrier approach each production station, the tag is read by
![](/img.php?id=514280&img=bg12.png)
Chapter 1: Getting Started
19
an RFID controller which first determines whether or not the engine should be at the
given station. If affirmative, the build information is read from the tag and transferred
back to the Host. The Host then instructs automated equipment such as computer
numerically controlled (CNC) mills, nut-runners and inspection equipment, to carry
out the build instructions for that production station.
After each operation is performed, important quality data and/or production results
are written to the tag before the engine carrier is sent to the next station. This allows
their workers to later investigate any quality issues quickly across varying lots.
Should an operation fail or is found to be unsuccessful, a failure code is written to the
tag. Then, as the engine carrier reaches the next production station, the failure code
is read from the tag and the engine is rerouted to a rework station. At the rework
station, the tag is once again read to determine where the failure occurred, why it
occurred and how the engine must be repaired. After successfully reworking the
engine, the successful code is written to the tag and the carrier can be transferred
back into the production line.
Furthermore, because time stamp and production station ID numbers are tracked
with each engine carrier, and are later stored in a master database, all engines built
at a given production station or within a specific time span can be easily identified.
Providing a means of locating only those parts that have common manufacturing
traits, this can be extremely useful should a quality concern arise and a recall is
required. RFID tracking has helped this company minimize the number of engines
affected in quality concern bulletins.
Also, because specific build instructions were initially written to the tag, the same
production line can be used to produce multiple engine models, eliminating the need
for dedicated production lines.
In the electronics industry, companies are taking the electronic manifests a step
further, by using RFID to enable production line operations to continue even if the
Host fails or goes off-line. With specific build instructions pre-written, the tag can
communicate directly with a local RFID controller at a given station, all build
instructions related to that station, are able to continue uninterrupted.
RFID Labels Make Television Sets “Smart”
During production, a large television set
manufacturer affixes RFID labels to the
inside housing of each television. After
utilizing RFID labels for tracking purposes
(as explained above), the labels accompany
the new "smart TV sets" into the warehouse.
In the warehouse, the labels are used for
locating a specific model and for routing
different models to their intended storage
locations.
Moreover, with the ability of RFID controllers
to communicate with multiple labels within
the same antenna field, all “smart TVs” can
be read or written to as they exit the
warehouse, regardless of whether the
televisions are stacked on pallets or
![](/img.php?id=514280&img=bg13.png)
Chapter 1: Getting Started
20
transported individually. This process enables the company to write destination
information to the tag and to record shipping invoices, providing the trigger for
automated electronic billing.
Upon reaching the distribution center, the "smart TVs" are read upon entering the
building, providing instant receipt for inventory systems and automatic payment for
suppliers.
The "smart TVs" are then
distributed and tracked into their
retail outlets where the label is
used for anti-theft and real-time
inventory management. Finally,
when the television is
purchased and leaves the store,
customer and product
information is written to the

• Mounting Surfaces: (where will the HF-0405 be mounted?)
• Temperatures: (Is the mounting area near sources of extreme heat?)
• Tag Memory and Memory Maps: (How much tag memory space will your
application require and have you developed a map outlining where your data will
be stored?)
• Read Only vs. Read/Write: (will your application read tags, write to tags, or
both?)
• Read/Write Range: (what is the projected distance between the proposed
mounting location and the tag path?)
• Disposable vs. Reusable Tags: (Will tags be reused, or will they be written off,
disposed or destroyed?)
• Target Tag Pricing and Volume: (How many tags will you regularly use and what
is the level of quality of the tag your application should have?)

Antenna Environment
The antenna that is used to communicate with RFID tags is integrated within the
housing module of the HF-0405 RFID Controller. Electromagnetic interference (EMI)
and the presence of metal near the reading field of the antenna can affect the
communication range of the RFID controller. The maximum distance from tag and
antenna should not be greater than 10cm.

Mounting the HF-0405
1. Select a suitable location for the HF-0405 where it will
be isolated from electromagnetic radiation.
2. Securely attach the HF-0405 to the L-Mounting
Bracket using the hardware provided. The HF-0405
has two mounting holes in the enclosure which will
accept the included screws. Recessed Hex patterns in
the enclosure eliminate the need for locking washers
on the nuts. Do not use thread locking compounds on
the screws or nuts.
Torque specification for screws: .7 Nm or equivalent 6 Lbs
/ inch. This goes for the controller screws as well as for the
mounting of the bracket.
3. Fasten the other end of the Mounting Bracket to the
work area you have selected. The controller may be
mounted horizontally or vertically but should be
mounted in such a manner that the LED indicators can
easily be seen during operation. Stay well within the
RF field of the controller for the tags you plan to use.
4. Maintain at least 20 centimeters minimum spacing between adjacent HF-0405
units (other RF devices operating on the same frequency may require greater
distances of separation).
Words of Caution
Avoid mounting the HF-0405 to metal or near sources of EMI and electrical noise. Do
not route cables near other unshielded cables or wiring carrying high voltage or high
current. Only cross cables at perpendicular intersections and avoid routing cables
near motors and solenoids. Because electrical noise from other sources can be
conducted through metal, a polycarbonate mounting bracket is provided to isolate the
HF-0405 from this potential cause of problems.
The 0405 Controller contains ESD sensitive components. Always observe ESD-
sensitive procedures when mounting the controller. Mounting the controller
improperly can damage the unit and may void the HF-0405’s warranty.
The HF-0405 is designed to withstand 8kV of direct electro-static discharge (ESD)
and 15kV of air gap discharge. However, it is not uncommon for some conveyor
applications to generate considerably higher ESD levels. Use adequate ESD
prevention measures to dissipate potential high voltages.

RFID Tags
Overview
RFID Tags, also referred to as transponders, smart labels, or inlays come in a variety
of sizes, memory capacities, frequencies, temperature ranges, read ranges and
embodiments. The HF-series controllers are capable of reading all of Escort Memory
Systems’ HMS and LRP series tags as well as tags made by many other
manufacturers. It is important to know that not all 13.56MHz tags are compatible and
even tags that are compliant to the ISO15693 or ISO1443 standards may not be
compatible with RFID controllers compliant to the same standards. This is because
these standards leave many features open to the discretion of the RFID equipment
manufacturers to implement or define. When using any tag other than those supplied
by Escort Memory Systems ensure compatibility of those tags with your RFID system
provider.
As of this publication, tags that contain the following RFID ICs are compatible with
the HF-0405-series controller.
HMS Series:
• Philips Mifare Classic, 1k-byte* + 32-bit ID (ISO 14443A)
• Philips Mifare Classic, 4k-byte** + 32-bit ID (ISO 14443A)
*Mifare 1k-byte is the total EEPROM memory in the IC. Of this
memory, 736-bytes are available for user data.
**Mifare 4k-byte is total EEPROM memory in the IC. Of this memory,
3,440-bytes are available for user data.

Chapter 2: Hardware Description

LRP Series:
• Philips ICODE 1, 48-byte + 64-bit ID
• Philips ICODE SLi, 112-byte + 64-bit ID (ISO 15693)
• Texas Instruments Tag-it, 32-byte + 64-bit ID (ISO 15693)
• Infineon My-D Vicinity, 1k-byte + 64-bit ID (ISO 15693)
The tags listed above are all are passive devices, meaning that they require no
internal batteries. These tags are read/write tags except for their unique ID number
(serial number) which is read only. There are no serviceable or repairable parts
inside a tag; however, most tags are rated for over 100,000 write cycles and 10-years
of data retention. The write cycle life specification of 100,000 times is actually a
conservative number as test results of over one million write cycles have been
recorded.
Many factors can affect the performance between the controller’s antenna and the
tag’s antenna. These include; the tag integrated circuit (IC), the antenna coil design,
the antenna conductor material, the antenna coil substrate, the bonding method
between the tag IC and the antenna coil, and the embodiment material.
Additionally, the mounting environment of the tag and controller can hinder
performance due to other materials affecting the tuning of either antenna. Escort
Memory Systems has spent extra effort to produce the best quality tags that obtain
optimum performance with our RFID controllers. In most cases, optimal conductivity
will be obtained when mounting the tag and controller antennas in locations free from
the influence of metals and EMI devices.
It is also important to select tags and controllers which have optimum inductive
coupling characteristics. Typically, the larger the tag’s antenna and the controller’s
antenna, the better the range performance achieved. However, mismatched antenna
sizes will have negative performance effects. Consider that the power and
communication between the tag and the controller is made through inductive
coupling between two coils as in a transformer. With a large antenna coil on the
controller side (primary winding) and a small antenna coil on the tag (secondary
![](/img.php?id=514280&img=bg1a.png)
Chapter 2: Hardware Description
27
winding) poor inductive coupling will occur. Additionally, the flux density of the
magnetic field may not be dense enough for the lines of flux to couple with a small
tag’s coil resulting in read nulls (dead spots) within the RF field. Alternately, a small
antenna coil on the controller side and a large antenna coil on the tag will also
produce poor results.
Given the variety of influences that may affect read and write performance, it is
important to choose the controller and tags with these concerns in mind and it is
always recommended to test the system on a small scale before implementing a
large scale installation. Be sure to review the tag datasheets to ensure proper
selection and the best combination of tags for your application.
Tag Embodiments
RFID Labels and inlays or inlets are
the lowest cost solution and are
typically used in an open
system in which the tag
leaves the facility on the
product or is destroyed
at the end of the
process.
The process of
creating the antenna
coil pattern is critical.
Typically, lower cost
processes such as printing,
produce the lowest quality
antenna. Low quality antennas go into
low quality tags that exhibit poor conductivity or
cracking when flexed.
An inlay is a substrate (polyester, Mylar etc.) with a printed,
screened or etched antenna coil. Sometimes the coil can even be
a wire that is laid down onto the substrate and is bonded to it with heat.
Typically the RFID IC is attached by means of flip-chip technology and the electrical
connections are made by means of conductive epoxies.
Wire wound coils tend to produce the most
efficient RF conductors and survive flexing
well but are often more expensive because
they take longer to produce. Labels or
Inlays with etched copper antenna coils
tend to be the most reliable low cost
solution, providing consistent low
resistance coils and flexible inlays.
However, because etching is a subtractive
process, much of the copper is etched
away during the fabrication process
resulting in higher prices due to the cost of
the metals being discarded.
Inlays can be applied to sticker-backed
paper to create label tags which is usually

done in large volumes on roll to roll production equipment. Inlays can also be used in
laminated cards such as smart credit cards, providing a low cost tag with some
protection from impact damage.
As RFID grows, there are many developments being made in the area of mass
production, low cost, quality antenna coils. One area of promise is the process of
electroplating printed or screened coils with copper to improve conductivity.
PCB Tags produced by Escort Memory Systems are designed for encasement inside
totes, pallets, or products that will offer the protection normally afforded by an
injection molded enclosure. These tags are
made from etched copper PCB materials
(e.g. FR-4) that are die bonded, by means
of high quality wire bonding, to ensure
reliable electrical connections that are
superior to flip-chip assembly methods.
The RFID IC is then encapsulated in epoxy
to protect it and the electrical connections.
Molded tags also utilize Printed Circuit
Board technology and are the most rugged
and reliable of the tags offered by Escort
Memory Systems. These tags are
designed for closed loop applications
where the tag is reused so the additional cost of the tag can be amortized over the
life of the production line. Typically these tags will be mounted to a pallet or carrier
that transports the product through the production process. Other applications for
these tags include, but are not limited to: embedding the tag into concrete floors for
location identification by forklifts and Automatically Guided Vehicles (AGVs), shelf
identification for storage and retrieval systems, and tool identification.
Escort Memory Systems offers a wide variety of molded tags that have been developed
over the years for real world applications. High temperature tags using patented
processes and specialized materials allow tags to survive elevated temperatures, such
as those required for automotive paint and plating applications.
Tag Memory
Tag memory varies in capacity and organization. The memory is organized in blocks
of bytes which vary from RFID IC manufacturer to manufacturer. Even when
compliant to ISO15693, the bytes and memory addressing can differ from one
manufacturer to another. Most commonly the bytes are organized in blocks of 4 or 8
bytes depending on the RFID IC. All of the bytes may not be available for data as
some bytes may be used for security and access conditions. For more information
about a specific RFID tag’s memory allocation, please refer to the IC manufacturers’
website for product data sheets.
Escort Memory Systems has taken great care to simplify the addressing of tag
memory. Mapping logical addresses to physical addresses is handled by the HF-
0405 Controller’s operating system. All a user needs to know is the starting address
at which data should begin and the number of bytes to be written or read. However,
extra attention should be paid to the memory block structure when memory lock
commands are used. When data is locked, it can never be changed. All data within
the block of addresses specified will be locked. Caution should be exercised when
using memory lock commands as it cannot be unlocked, even by Escort Memory

Systems.
Tag memory addressing begins at Address 0, therefore the highest addressable
memory location is one less than the total number of bytes in the tag (address count
does not start at one). Each address is one byte (8-bits) and a byte is the smallest
unit addressable. For example, writing 8-bytes of data beginning at address 0 will fill
addresses 0 to 7 with 64-bits of data in all.
Tag memory size is often specified by the number of bits, as this produces a larger
number (8x) and inflates product specifications. Escort Memory Systems however,
prefers to specify tag size in terms of bytes, as it is typically what our customers are
really interested in knowing and more closely reflects how the data is stored and
retrieved from a tag.
Tag Memory Map
For any application, the use of the tag memory should be well thought out. It is
advisable to allow more memory space than is initially required, as inevitably a need
will arise to store more data. A memory map is simply a definition of what data will be
stored at what locations on the tag for the application. For example:
Example of a Tag Memory Map
Address 00 -15: Product Serial Number
Address 16 - 47: Model Number
Address 48 - 63: Date of Manufacture
Address 64 - 71: Lot Number
Address 72 - 87: Factory ID
Address 88 - 111: Reserved for future use
Memory Optimization
In the example above, a 112-byte tag is used. This may not seem like much data
storage space when one considers that this would only allow for a short paragraph of
alpha-numeric characters. But employing a sophisticated memory map utilizing all
896-bits in this tag would provide much more usable data space in the tag.
It should first be understood that data is always stored in tag memory in a binary form
of 1’s and 0’s. The standard method of notating binary data is to use the hexadecimal
numbering system. Otherwise it would be far too confusing looking at a screen full of
1’s and 0’s.
Below is an example of how hexadecimal notation simplifies the expression of
decimal and binary numbers. This example shows the decimal value 52,882, its
binary equivalent and its 2-byte Hex integer:
Decimal Binary Hexadecimal
52,882 1100111010010010 CE92

Chapter 2: Hardware Description

When the character “D” is typed on the keyboard, for instance, the ASCII code
representing the capital “D” is stored to the tag, which, in this case, would be the
hexadecimal value 0x44. So in the example above, instead of using 5-bytes of data
to store the ASCII bytes representing characters 5, 2, 8, 8, and 2 (ASCII bytes: 0x35
0x32 0x38 0x38 0x32) simply writing the two bytes 0xCE and 0x92 serves the same
purpose while using 60% less memory space on the tag. (Refer to Appendix C in this
document for the ASCII table).
Additionally, if a database program with look up values is used in the RFID
application, the logic level of the individual bits in the tag can be used to maximize
tag memory.
The following example shows how a single byte of data can be used to track an
automobile at eight production stations. The binary value one (“1” ) in this example
represents a required operation and the value zero (“0”) represents an operation that
is not required.

ISO 1443A/B
RFID ICs designed to support ISO 14443A and/or 14443B were originally intended
for use in “smart cards.” Today, for example, smart cards are being used to facilitate
financial transactions in banking, passport, bus and ski lift ticketing applications. For
this reason there are many security authentication measures taken within the “air
protocol” between the RFID controller and the tag.
Escort Memory Systems was the first RFID company to adopt ISO 14443 Standards
into its’ RFID ICs which were initially designed for industrial automation applications.
Because the typical RFID application does not require security levels that of which
monetary applications necessitate, certain security features have not been
implemented in the HF-0405 Controllers. It is important to understand the security
requirements of your application before assuming the HF-0405 is suitable.
Tags that have built-in security features require the exchange and authentication of
software “keys”. To authenticate communication and permit the transfer of data to
and from the tag, the RFID controller and tag must use the same security keys.
This authentication ritual is carried out with every command from the RFID controller
and on every block of tag data. The HF-0405’s operating system (HFOS) manages
security transparently to the user. The HF-0405 not only supports Escort Memory
Systems’ security keys, it supports the default transport keys supplied by many other
IC manufacturers.
ISO 15693
The ISO 15693 Standard was established after the RFID industry identified that the
lack of standards was preventing the market from growing to a greater potential. At
the time, Philips Semiconductor and Texas Instruments were the two major chip
manufacturers producing RFID ICs for the ISM frequency of 13.56MHz. Yet each
used their own unique protocol and modulation algorithm. Through ISO 15693, Texas
Instruments’ Tag-it and Philips Semiconductors’ ICODE product lines were
standardize on mutually compatible standards.
After standardizing to ISO 15693, the door opened for other silicon manufacturers to
enter the RFID business, many of which have contributed to this and other ISO
Standard definitions.
This healthy competition has spawned rapid growth in the industry and has led to the
development of other standards, such as ISO 18000 for EPC applications.
ISO 18000-3.1
The ISO 18000 standard has not been implemented in the HF-series controller at the
time this guide was published. It is, however, a planned product enhancement for
future release which will provide support for EPC and UID tag applications.
