14 Modes of Operation EZReader HF & EZTune Antenna Installation & User Guide
Accu-Sort Systems, Inc.
Trigger Inputs 1 and 2
Two optically isolated inputs or two non-isolated inputs are available
on the I/O Port. These inputs are used when the unit is in Hardware
Trigger Mode of operation and allow the unit to operate
autonomously. When using isolated inputs user must supply both
positive and negative voltage references. When using non isolated
inputs user must connect to sink output of trigger device (active low).
A current limited (100 ma max combined Trigger 1&2) 12VDC
connection is available for purposes of providing power to low current
consuming devices such as a photo-eyes. Non isolated inputs are
internally pulled to +5VDC through a 2.2k ohm resistor.
NOTE: Avoid sourcing any current into the Non-Isolated
Trigger inputs. Failure to do so can damage unit.
Outputs 1 and 2
Two Solid-State Form A Relay Outputs are available on the I/O Port.
These outputs can be configured by the user to close on various
conditions such as valid or invalid tag reads. The outputs can also be
controlled by remotely by the user.
NOTE: Relay Outputs are capable of switching DC
voltages(30 VDC max@250 ma) only. Applying AC
voltages will damage unit.

Antenna Mounting
General Guidelines
To achieve optimum performance from the EZReader HF, the
antenna should be mounted as far from metal objects as possible.
The RF energy generated by the Reader/Antenna combination to
communicate with the RFID tags is called the near field. The near field
is the magnetic portion of the RF field and can be influenced by
surrounding metallic objects. These metallic objects if located close
enough to the antennae and are of the right shape and position can
create eddy currents, which diminish and in some instances can
totally cancel out the reading ability of the antenna. These metallic
objects also will detune the antennae which in turn will cut down on
the power transfer between reader and antenna leading to less then
optimum performance.
To cover all possible antenna mounting possibilities is beyond the
intent of this document, but an example of one way to help reduce the
influence of metallic objects on the antenna is shown below. The 5” x
16” antenna is shown in this example being mounted in a roller
conveyor.

EZReader HF & EZTune Antenna Installation & User Guide Modes of Operation 23
Accu-Sort Systems, Inc.
Modes of Operation
The EZReader HF modes of operation can be divided into three
categories. The reader can be in Setup mode where the user can
change parameters, or it can be in HardwareTrigger mode where the
unit acts only on trigger inputs, or it can be in Host Control mode
where the unit functions based on commands it receives from a Host.
See following sections for in depth details on each mode.
24 Modes of Operation EZReader HF & EZTune Antenna Installation & User Guide
Accu-Sort Systems, Inc.
Setup Mode
All of the user changeable parameters can be configured in setup
mode. These settings will be stored in non-volatile memory only if they
are saved after changing. Due to the vast number of user defined
parameters and their interaction Accu-Sort recommends using the
EZReader HF Interface GUI for configuring the reader. See GUI
section.
Entering Setup Mode
Setup mode can be entered by using the GUI and either connecting a
1 to 1 Serial Cable (included with the EZReader HF Accu-Sort Part #
0111343001) between your PC and the Reader or thru a Ethernet
connection. It is recommended to use the Serial connection the first
time as you do not need to know any of the units Network settings to
connect.
When choosing to use the Network Setup connection you will need to
configure your LAN settings to be compatible with the unit’s settings.
The default Network settings are as follows:
IP Address: 192.168.178.252
Net Mask: 255.255.255.0
Gateway: 192.168.178.252
The Serial SETUP Port settings are fixed as follows:
57600, N81
The data format of this port is also fixed and is as follows:

Hardware Trigger Mode
In this mode the EZReader will operates autonomously. It will only
perform Tag Read functions and send data to the Host when its
Triggers are activated. The unit can use one or two triggers
depending on the application.
When using a single Trigger the Trigger1 input must be used and the
unit will read based on a timeout set by the user.
When using two triggers, Trigger1 will start the Tag Read cycle and
Trigger2 will end it.
In both cases the number of Tag memory blocks to be read is
programmable.
In Trigger Mode, all commands sent by the Host (Serial or Ethernet)
are ignored by the EZReader HF, it will only send data on these ports.
The only port that will respond to queries is the Setup Port.
NOTE: A trigger signal must be active for a minimum of
10ms to be accepted.
Trigger Mode Examples
The following examples will be based upon the tag data shown in the
screen capture shown below.
The Tag UID is: Hex E0 07 81 26 AD 83 5D 67 (unless otherwise

Host Control Mode
When in Host Control Mode, the EZREADER-HF will only respond to
requests received on its Host serial or Ethernett ports. All activity on
the Trigger inputs will be ignored.
All commands regardless of which port they are received on require a
Receive Header and Trailer. “STX” is the default Receiver Header and
“ETX” is the default Receive Trailer. The Header and Trailer cannot
be the same if changed.
Messages from the EZREADER-HF will include TRHDR and/or
TXTRL (if they are enabled, “STX and “ETX” are again the defaults),
as well as the requested data. The general format (with all fields) is:

Host Control Mode Commands
Note for all examples shown assume that the unit has its setup
parameters at their default values. Receive Header and Trailer are as
follows:
Receive Header: “STX” (02 hex)
Receive Trailer: “EXT” (03 hex)
Transmit Header: “STX” (02 hex)
Transmit Trailer: “ETX” (03 hex)
“E” End current continuous reading commands
The “E” command is sent to end commands that have put the
EZREADER-HF in a continuous read condition. Commands that
require the “E” to end them are “I” (Inventory) and the continuous read
commands; R04, R05, R06, R07. The EZReader will echo the “E”
command back to the Host when received.
NOTE: Commas are shown for clarity purposes and are
not part of data.
• NP stands for Non Printable character.
• NA stands for Not Applicable so no character will be
sent.

“I” Do an inventory of tags.
Report the UIDs of tags in proximity to the antenna. Once the UID of
the tag has been read, it will be in “Quiet” mode until the tag leaves
the field of the antenna.
Note that the bytes of the UID are output in reverse order (the same
order that the EZREADER-HF expects the UID in a command).
Example ASCII HEX
Command STX,I,ETX 02,49,03
Response [Many NP characters] 02,67,5D,83,AD,26,81,07,E0,03
Tag will be in “Quiet” mode until the tag leaves the field of the
antenna. To stop the inventory, type “E” (RXHDR and RXTRL is
necessary).
“L” Lock blocks.
There are two available options available:
• L00bb
Locking a block prevents writing data to the specified block. This is a
permanent irreversible change to the tag.
If the lock is successful, the response will be TXHDR (if any), “YL”
(Yes Lock), and TXTRL (if any).
The example below is locking block 30 of a tag that is in the antenna’s
field.
Example ASCII HEX

Continuous read and transmit of block bb.
Block bb is read continually from whatever tag is in the antenna field
until the EZREADER-HF receives an “E” end continuous command
(no RXHDR or RXTRL is required). This is most useful for a stream
of tags passing a fixed antenna. Note that this command will
continually send data if a tag is read, care should be taken by the end
user to appropriately manage the host system receive buffers. If no
Tag is read there will be no data sent
The example below will continually read and transmit block 01 of the

NOTE: There is a limit of 20 characters (a total of 5
blocks) in the data read from the tag for this command.
The example below will start reading at block 00 and will also read 4
additional blocks of data starting from the first block after 00, but will
transmit the data only one time.

Response NA NA
This turns off the RF carrier (unit’s transmitter turned off).
This can be useful after an Inventory command, since turning off the
carrier will clear the “Quiet” mode of the tag.
“W” Write to tag.
There are three available options: writing a single block (W00), writing
multiple blocks (W01) and writing a single block using the Tag UID
(W02). Commands W00 and W01 will be used in almost every
application.
• W00bbdddd
Write data dddd to block bb.
Note that the data dddd is 4 binary bytes (each byte can have any
value, 0x00 to 0xFF). While the examples in this document use ASCII
characters for clarity, this is not a requirement.
If the write is successful, the response will be TXHDR (if any), “YW”
(Yes Write), and TXTRL (if any).
An unsuccessful write can reply with any of the following errors:
NO TAG
NO ANT
COLL
MISREAD
NW<ISO flags>
The first four are normal EZREADER-HF error messages, the fifth is
based on the ISO Flag Byte, and probably represents trying to write to

• W01bbnndddd…..etc
Write data dddd starting at block bb thru nn additional blocks. This is
the multiple block write command, when using the amount of data
sent must exactly match the number of blocks to write.
Note that the data dddd is 4 binary bytes (each byte can have any
value, 0x00 to 0xFF). While the examples in this document use ASCII
characters for clarity, this is not a requirement.
If the write is successful, the response will be TXHDR (if any), “YW”
(Yes Write), and TXTRL (if any).
An unsuccessful write can reply with any of the following errors:
NO TAG
NO ANT
COLL
MISREAD
NW<ISO flags>
The first four are normal EZREADER-HF error messages, the fifth is
based on the ISO Flag Byte, and probably represents trying to write to
a locked block.

Troubleshooting
Reader not responding to serial commands:
6. Verify the power indicator is lit, if not apply power to the unit.
7. Verify the serial communications indicator flashes when a byte is
sent
8. Check communications cabling.
9. Make sure unit is configured to work on the port and baud rate
that you are using.
10. Verify you are using the correct headers and trailers and both
Trigger settings are (0).
NOTE: See Setup mode of operation for further details on
configuring unit.
Unable to read a Tag present in the field (Tag Comm indicator
does not light):
11. Check antenna cabling.
12. Ensure the antenna is not near any metal surfaces or sources of
EMI.
13. Check antenna indicator ensuring that it matches port connected
to antenna.
14. Make sure protocol is correct for the tag type being used.
15. If using a terminal emulation program ensure that printable
characters are programmed into tag.
16. Ensure that antenna is tuned properly. Perform EZTune
17. Ensure that tag is not being detuned by article that it is attached
to. Items such as metal and conductive plastics that contain
carbon will detune tag and reduce its performance. Items that are
carried within article that tag is attached to may also lead to
detuning of tag.

Reader does not respond to a trigger
1. Verify Trigger cabling is correct.
2. If using Non-Isolated inputs, be aware the trigger is active low and
should be connected to an open collector type drive circuit. If
using isolated inputs you must provide both positive and negative
voltage connections.
3. Verify that the Trigger you are using is set up properly.
4. Verify Trigger signal is asserted for more than 10ms to overcome
internal debounce.

Term Definition
Screen Represents the information display area of your computer monitor. Also referred
to as a desktop.
Window A window is a box around a set of related information on your screen. Many
windows can appear on your screen simultaneously and can overlap, appear
adjacent to, or on top of each other. You can move a window to a different
location on your screen.

Interface
Window Title
Each window title is identified by the highlighted folder or check-marked selection
in EZReader HF menu tree. Window titles may also appear at the top of new
windows that appear on-screen.
EZReader HF
Interface Setup
Window
Whenever you launch EZReader HF Interface, the EZReader HF Interface
window appears on your screen. This window displays the drop-down menu bar,
toolbar, EZReader HF Interface Wizard and EZReader HF menu tree.
EZReader HF
Interface
Wizard
Use the EZReader HF Interface Wizard’s 3 buttons (previous, next, and reset) to
logically step through the process of completely configuring an EZReader HF and
its antenna. Recommended for first-time/novice users.
EZReader HF
Menu Tree Use the EZReader HF Menu Tree’s navigation list when you need to modify
specific setup parameters, save/retrieve settings, or access reader diagnostics.
Confirmation
Box Certain actions you perform in EZReader HF Interface may cause a modal
window to display. A confirmation box requires you to act on its contents before
you can continue, usually by choosing OK or Cancel.
Block Every EZREADER HF INTERFACE window consists of one or more blocks
containing information on specific setup parameter. All required fields in a block
must be completed before you can move to the next block or setup window. The
first or only block in a window assumes the name of the window. Otherwise, block
names appear across the top of the block. A horizontal line marks the beginning
of the block.
Region A region is a collection of logically–related fields set apart from other fields by a
rectangular box. Each block can optionally contain one or more regions. Regions
help to organize the information within a block. A scrollable region is a region
whose contents are not entirely visible in a window. A scrollable region contains a
horizontal or vertical scroll bar so that you can scroll horizontally or vertically to
view additional fields hidden in the region. In addition, if a field is partially hidden
you can scroll the region to fully display the field by clicking on the partially hidden
field.
Field Each block contains fields you use to enter, view, update, or delete information. A
field prompt describes each field by telling you what kind of information appears
in the field or what kind of information you should enter in the field. Fields that
allow you to enter data are white and display a beveled border. Fields that are
display–only are white and do not have a beveled border. If a field is disabled, it
is dimmed. The term field generally refers to a text field, an area in a window that
either displays data or allows you to enter data.
Check box You can indicate an on/off or yes/no state for a value by checking or unchecking
its check box.

ACK - A control character sent to acknowledge that a transmission block has been received.
active/passive device - In 20mA current loop communications, a device capable of providing the
current for the loop (active) and a device that draws the current from the equipment it is connected to
(passive).
Active tag- An RFID tag that has a transmitter to send back information, rather than reflecting back a
signal from the reader, as a passive tag does. Active tags generally use a battery to transmit a signal to
a reader. However, some tags can gather energy from other sources.
address - A unique designation for the location of data or the identity of a smart device; allows each
device on a single communications line to respond to its own message.
alphanumeric - The character set which contains letters, digits and other characters such as
punctuation marks.
Amplitude- The maximum absolute value of a periodic curve measured along its vertical axis (the
height of a wave, in layman's terms).
Amplitude modulation-. Changing the amplitude of a radio wave. A higher wave is interpreted as a 1
and a normal wave is interpreted as a zero. By changing the wave, the RFID tag can communicate a
string of binary digits to the reader.

U.S. A non-profit, non-governmental group supported by over 1000 trade organizations, professional
societies, and companies. Member body to the ISO (International Standards Organization).
Antenna- An RFID tag antenna is the conductive element that enables the tag to send and receive
data. Passive, low- (135 kHz) and high-frequency (13.56 MHz) tags usually have a coiled antenna that
couples with the coiled antenna of the reader to form a magnetic field. UHF tag antennas can be a
variety of shapes. Readers also have antennas which are used to emit radio waves. The RF energy
from the reader antenna is "harvested" by the antenna and used to power up the microchip, which then
changes the electrical load on the antenna to reflect back its own signals.
Antenna gain- In technical terms, the gain is the ratio of the power required at the input of a loss-free
reference antenna to the power supplied to the input of the given antenna to produce, in a given
direction, the same field strength at the same distance. Antenna gain is usually expressed in decibels
and the higher the gain the more powerful the energy output. Antennas with higher gain will be able to
read tags from farther away.
ASCII (American Standard Code for Information Interchange) - Pronounced ask-ee. A seven bit
plus parity code established by ANSI to achieve compatibility between data services.
asynchronous transmission - Transmission in which the time intervals between transmitted
characters may be of unequal length. Transmission is controlled by start and stop bits at the beginning
and end of each character.
baud rate - A unit used to measure communications speed or data transfer rate; represents the
number of discrete conditions or events per second.
BCC (Block Check Character) - Used to check transmission accuracy, a character transmitted by the
sender after each message block and compared with a block check character computed by the
receiver.
bed width - The width of the conveyor bed measured in inches.
BEL - A control character that is used when there is a need to call for attention; it may control alarm or
attention devices.

serial asynchronous transmission of data - The following are common communications interfaces:
RS232, RS422, RS485, 20mA current loop and RS423.
When data is transmitted serially from a communications port, the information is transferred
between the two devices one data bit at a time. The data flow can follow one of three different
communications modes: simplex, half duplex, or full duplex. Each character of data within the
data flow is transported in a binary bit frame called the asynchronous data frame.
The start bit begins each frame. A low voltage signal on the data communications line marks the
beginning of the start bit, at which point the receiving device begins looking for binary zeros and
ones (0s and 1s). The following five to eight data bits (the number depends on the format used)
comprise the binary character. For error detection, an optional parity bit can define whether the
total number of zeros or ones was even or odd.

• OFF (NONE) - last data bit is not present.
The method used to catch errors by using parity bits is as follows: When the transmitter frames
a character, it tallies the number of 0s and 1s within the frame and attaches a parity bit. (The
parity bit varies according to whether the total is even or odd.) The receiving end then counts
the 0s and 1s and compares the total to the odd or even recorded by the parity bit. If a
discrepancy is noticed by the receiving end, it can flag the error and request a retransmission of
the data.
A stop bit is used to signal the end of the character. Stop bits are typically one or two bits in
length. The slower the transmission speed, the more stop bits required for recognition of the end
of the data frame.
In addition to the direction of data flow and the data framing, there are other considerations to
insure uniform transmissions. Certain operating parameters must be followed to prevent the loss
of valuable data.
The first consideration is the speed of transmission, known as baud rate. Serial data
transmission is measured in bits per second (BPS). The baud rate selections available for the
6000 are: 110, 300, 1200, 2400, 4800, 9600 and 19200. To enable two devices to interact, they
must both be transmitting/receiving data at the same baud rate. If it is not possible to do this,
there must be a buffer (typically additional storage memory) that accommodates the differences
in communications speed.
Many serial communications links also use a flow control system to handle data transmission in
addition to memory buffers.
X-ON/X-OFF Protocol
A common type of flow control is the X-ON/X-OFF protocol. When a receive buffer nears its
memory capacity, the receiving device sends an ASCII X-OFF signal to the transmitting device,
telling it to stop sending data. When the memory buffer has enough space to handle more data,
the X-ON signal is sent to the transmitting device, telling it to start sending data again.
ACK/NAK Protocol device transmits a message to the host, the host responds with either an
ACK (06H) or a NAK (15H). If the host transmits an ACK to the device, the device deletes its
transmit message and the communication sequence is complete. If the host transmits a NAK,
the device will retransmit. The device resends data a maximum of three times. Optionally this
may be changed to 1, 2, 3, or infinite retransmits by the user. If the device receives a fourth
NAK, it will delete the data in its transmit buffer and display "MAX REXMITS."
A transmitting device ignores ACK and NAK characters received during data transmission. If, for
example, a device receives a NAK during a data transmission, it will not resend the data at the
completion of the transmission.
The device also has a retransmit timer. This timer is activated each time the device transmits
data to the host. If the timer runs for two seconds (this is also changeable) and the device does
not receive an ACK or NAK from the host, a timeout occurs and the device retransmits its data.
Each time the device retransmits because of a timeout, it treats the timeout the same as
receiving a NAK from the host computer. If the device does not receive an ACK before the end
of the fourth timeout, it will delete the data in its transmit buffer and display "MAX REXMITS."

The device deletes data in its transmit buffer and displays the error message when any
combination of four timeouts and NAKs from the host occurs.
When the device receives a message from the host, it calculates the BCC for the message and
compares the calculated BCC to the received BCC. If the two values match, the device
transmits an ACK, ending the communication. If the values do not match, the device transmits a
NAK to the host and waits for the host to retransmit the message. The host, like the device,
should retransmit a maximum of three times.
The sequence number starts at zero (30H) and is incremented each time a device transmits a
new message. When the sequence number reaches nine (39H), it wraps around to one (31H). If
the sequence number skips a number, the receiving device knows that a message was lost. If
the same sequence number is received on two sequential messages, the second message is
responded to with an ACK or NAK (as appropriate) and ignored.
shielding - Protective covering that eliminates electromagnetic and radio frequency interference.
side read - The scanner/antenna is mounted to read the side of a box as it passes by the head.
signal - An impulse or fluctuating electrical quantity (i.e.: a voltage or current) the variations of which
represent changes in information.
Singulation- A means by which an RFID reader identifies a tag with a specific serial number from a
number of tags in its field.
slider bar - A graphical user interface that enables the user to select an ascending/descending value
for a definable parameter by clicking on the slider bar and then sliding (via the mouse) until the desired
value is shown.
software cart - A serial message from an external device that controls the cart cycle.
spot - The undesirable presence of an area of low reflectance in a space. start and stop characters
start and end of cart photoeyes - The cart cycle begins when the start of cart photoeye is blocked
and continues until the end of cart photoeye is unblocked. Relay decisions and data communication
take place after the end of cart photoeye is unbroken.
start bit - In asynchronous transmission, the first bit or element in each character, normally a space,
that prepares the receiving equipment for the reception and registration of the character.
stop bit - The last bit in an asynchronous transmission, used to indicate the end of a character,
normally a mark condition, that serves to return the line to its idle or rest state.
STX (Start of Text) - A transmission control character that precedes a text and is used to terminate a
heading. (^B)
syntax - The rules that dictate how the user must type a command or instruction so that the computer
will understand it.
system.ini file - When the user starts Windows, it consults the system.ini file to determine a variety of
options for the Windows operating environment. Among other things, the system.ini file records which
video, mouse, and keyboard drivers are installed for Windows. Running the Control Panel or Windows
Setup program may change options in the system.ini file.
tachometer (tach) - Hardware device used to provide conveyor speed information to the scanner or
camera in x pulses per inch.
tag - A collection of information associated with a single variable or I/O point.
tap(s) - Taps (or channels) refer to the number of data paths out of the linear CCD sensor. A linear
CCD sensor consists of a line of light-sensitive areas. The charge collected in all these areas is shifted
to a parallel array of non-light sensitive holding areas all at once. The charges are then shifted along
the second set of areas in a bucket brigade fashion with the last areas charge being shifted off the
sensor entirely (for further processing). This holding area does not have to all be shifted out of a single
port the holding line may be broken into several sections, each with its own exit from the sensor. Each
exit is called a tap or channel. Generally, the more taps the more quickly the image data may be shifted
