The Allflex Panel Reader comprises 2 parts, the antenna and the reader control electronics.
The reader section is the electronics that generates the signal used to excite (power up) the
RFID device (Radio Frequency ID). The device is also referred to as a transponder, electronic
ID (EID), as well as electronic eartag , etc. The reader also decodes the signal returned from
the RFID device. The transmission and receipt of signals between the reader and the RFID
device is done via the antenna. The antenna is a specifically designed coil of copper wire
enclosed within the plastic panel.
The Allflex reader is designed to
read devices that meet international
standards ISO 11784 and 11785.
NLIS devices are ISO compliant
devices. The reader electronics are
housed inside a control box that
also includes an ammeter, indicator
lamps etc. The control box is
usually fastened to the antenna
using 2 x 5mm countersunk
stainless steel screws. Please see
Assembly Section.
A cable is supplied to provide
12volts DC to the control box. This
cable can be clearly identified
because it has alligator clamps on
one end. The power source should
be a standard automotive, truck or
marine battery. A 240 Volt – 12
volt linear power supply is also
available as an option.
Note : Only the approved linear
240volt supply should be used
because most 240 volt supplies will
generate electrical interference that
may cause the reader to perform
poorly. A second cable, the
The Allflex Medium Panel Reader
(600mm x 400mm)
communications cable, is also
supplied to join the control box to a
computer, scale head etc.
Each Panel Reader is factory tuned for optimum performance in an environment free from
metal structures. Typically, the system will operate without user adjustment in many
installations. Pre-drilled mounting holes in the black panel facilitate user installation, so that
total system setup is fast and easy.
This instruction guide provides the user / installer with information about mechanical
installation, electrical wiring, configuration, operation, and performance characteristics of the
Panel Readers.

Portal Antenna:
The portal antenna is an optional replacement for the flat panel
antenna and forms a tunnel that is placed in a stock race. The tunnel can be used bi-directionally. It is
a structure formed from plastic that has a vee section base and rises from the ground at an angle of
around 60 degrees as shown in the image and sketches below. Note – the portal joins to the control
box via the blue cable supplied.
Into the structure an antenna is wound an antenna. The antenna involves multiple turns of
conductor to form a loop. The loop runs parallel to the edge of the structure so the animal will
pass through the loop as it enters the portal / tunnel.
Rev Australasia V2.3 12/04
The wire is then laid over to the other edge of the structure, where a second loop is wound. This
loop is at the edge where the animal will exit the structure. Therefore the animal will walk
through 2 loops formed from one single conductor. The start of the wire and end of the wire
terminate at an electrical connector to allow circuit connection to the control electronics.
The first coil and second coil are wound in opposite directions (out of phase). This increases
immunity to electrical noise.
The antenna structure is located between metal pipes section around 1 metre long that run in a
horizontal plain. These can simply be sections of metal gates. Ensure they are very firmly
fastened so that vibration of the metal is not evident.
These pipes act as radiators to expand the antenna read field. The metal bars also allow better
coupling with the tag when in a horizontal plain. Many sheep RFID tags sit in a horizontal plain
and for a simple panel antenna this is the worst orientation. However, in the portal reader, the
effects of tag orientation are essentially removed because of the metal radiators and the fact that
Rev Australasia V2.3 12/04
the read field is laid over at 6o degrees. The Images below show tags being read in various
Another benefit of laying the coils over at an angle is to ensure that if a null zone is formed in the
centre zone of the antenna, it (the null zone) will be on an opposing angle of 60 degrees. This
means that it will be almost impossible for an animal to move through the antenna and follow the
null zone (60 degrees to horizontal). Allflex has a Patent Pending for the portal reader.
Naturally a key benefit of the portal reader is that there is far less dependency upon what ear
carries the RFID device.
Rev Australasia V2.3 12/04
The portal can be fastened directly to the metal pipes, or tied firmly in place.

Mechanical Installation
Choosing an Installation Site
Several factors should be considered when selecting and / or constructing an installation site
in order to ensure optimum performance of the Panel Reader. Prior to making structural
changes to the target installation site, the user should temporarily install the reader in a
manner that as closely as possible simulates the permanent installation.
(a) Metal surfaces and structures - The Panel Reader uses radio frequency techniques to
communicate with the eartags. Metal material, especially metals that are magnetic can
seriously degrade the read range performance through absorption and deflection of the
Panel Reader’s electromagnetic fields.
The reader cannot usually read through sheet metal. However, in some cases this is
possible and the reader can usually be configured to read through metal pipes and still
achieve good read distances as demonstrated in the images below.
Note that in the images above, the reader has literally been tied directly to the metal bars.
In a practical installation, Allflex would recommend that you use a piece of marine
plywood (or similar) in between the metal bars and the reader so that the reader is
protected from direct impact from horns etc. Also in some cases, when mounting through
steel bars, it is necessary to mount the antenna away from the bars. This depends upon the
type of crush and the configuration of the pipe work.
If you do intend to mount the antenna to read through metal pipes, position the antenna so
that the antenna coil, (the raised section) does
not sit directly above the pipe work. Try and
position the antenna so the coil is offset / spaced
between the pipe work as shown.
Another issue to consider that will dramatically
effect the performance of the reader, is to avoid
positioning the antenna so that metal bars run
parallel to the antenna coil forming a frame
closely around the coil.
Hold the antenna in place or temporarily tie it in
the desired location.
Check the current
displayed on the ammeter. Ideally, it should be
around 1 amp. You may find that by simply
Raised section
is the antenna
Rev Australasia V2.3 12/04
lifting one side away from the steel pipes, the current and read distance will be excellent.
Verify that sufficient read range performance is possible.
Note the screw driver blade sitting between the panel and the steel.
The good read distance shown above has been achieved by lifting one edge off the steel.
If you do temporarily position the reader like this, you can then mount the panel reader on
ply in the desired position. You can adjust the current up to around one amp, which
should give you great reading results, by either packing the antenna off the steel a little
(using spacers), lifting one edge away from the steel (as shown above), or by adjusting the
Tuning is a process that will adjust the antenna to perform in an area where an amount of
conductive metal is in close proximity. This is discussed in detail later, however, if you
require assistance, please call Allflex for telephone support. Allflex Australia – 07 3245
9100. Allflex New Zealand - 06 356-7199.
In some cases, it is more practical to mount the antenna on a non-metallic material such
as timber and simply fit this into the crush (as shown below). This allows easy,
installation and removal where the antenna is moved often and also provides excellent
read distance.
Rev Australasia V2.3 12/04
Antenna mounted on ply
When you do mount a reader onto the steel pipe work of a crush etc, you will find the
antenna transmits energy into the pipe work. What often happens is that the crush actually
starts acting like an extension to the antenna. This is called the Parasitic Effect. For
example, if you mount an antenna close to the front of a crush, (head bail end) you may
notice that tags read outside the normal read range when they come close to steel pipes
positioned at the entry to the crush (as shown below).
Usually, this parasitic effect is really helpful because it means that the animal is detected
very quickly as it enters the crush or drafting crate, however, it may also mean that the
system is very fast to read animals that follow closely the animal in the crush (IE if a
second animal places it’s head in beside the first beast, you may read the first animal and
then the second, with the second animal being displayed on your computer or scale head).
You need to understand how to deal with this situation if it occurs and how it affects the
Rev Australasia V2.3 12/04
data capture process either into scale heads, or the computer that you are using. In most
cases the software has a means of coping with this.
(b) Electrical Machinery - Most 240 volt AC operated electrical machinery will not interfere
with the Panel Reader’s electrical signals. However, machinery that is electrically
controlled by electronic methods, such as motor speed controls, light dimmers, and solid
state relays can produce high frequency emissions that can cause interference. When the
Panel Reader is being trial installed, the user should run all the machinery in the vicinity
to ensure that all potentially interfering sources do not exist. When wiring an AC mains
operated power supply for use with the Panel Reader, avoid wiring the AC connection to
the same phase as such electric machinery is wired.
(c) Other Eartags - If the Panel Reader is being installed in a location where eartagged
animals will exist on all sides of the Reader (such as a feeder), precautions must be taken
to ensure that only animals within the designated reading zone are read. This can usually
be achieved by positioning sheet metal, or mesh in an appropriate location between the
reader and the area where you want to “block” reading. If you do have multiple eartags
simultaneously present in the read zone of the antenna, either eartag might read, both
eartags might read, or neither eartag might be read.
(d) Other Readers - Operating multiple Panel Readers within close proximity, or operating a
mobile hand-held reader nearby a Panel Reader, can reduce the read range of all readers
present. In some cases this can totally inhibit reading of all readers. If multiple readers are
to be used in proximity to each other, it will be necessary to synchronize the readers.
Synchronization will require additional hardware equipment. Please call Allflex for
assistance with synchronization. Allflex Australia – 07 3245 9100. Allflex New Zealand 06 356-7199.
Once a suitable location site and installation method have been determined, the Panel Reader
can be permanently mounted in position using the ¼” (6mm) pre-drilled mounting holes. If it
is necessary, alternate or additional mounting holes may be drilled by the user, using caution
to drill only within the rectangle defined by the existing mounting holes. Standard steel bolts
will not compromise Panel Reader performance.
Note - The Panel Reader is designed to be completely water-tight. While not intended for
installation immersed in water, contact with water spray, such as heavy rain or power washers
is acceptable.
Caution! - Ensure that the mounting structure itself is sufficiently strong enough to endure
impact by animals that will come into contact with it. Do not rely on the Panel Reader to
contribute to the structural strength of the installation.
Rev Australasia V2.3 12/04
Electrical Installation
Electrical installation consists of making the appropriate power and data connections to the
user’s equipment. In some installations, where multiple Panel Readers are located and
operating at the same time, synchronization wiring will be required.
Power Source Requirements
The Panel Reader is supplied with a cable that allows direct connection to an automotive,
truck or marine battery. A 240 volt powers supply is also available as an option. It is
recommended that you use a well charged automotive battery or the recommended 240
supply. This is important because the 240 volt supply is a “linear” regulated type unit rated at
12 VDC output and 3.0 amperes minimum. Some AC power supplies may exhibit excessive
noise that can compromise read range of full duplex (FDX-B) (sheep / small stock) type
transponders. AC power supplies should be rated at 3 millivolts or less output ripple.
Users can purchase the recommended power supply from Allflex. It will be supplied in an
appropriate weather-proof enclosure (IP56). Alternatively, users can purchase their own
linear power supply and have a suitably qualified electrician mount the device into an
appropriate enclosure. The linear supply required is a Condor brand, part number HC12-3.4+.
The part can be purchased directly for a company called RS Components for around Aus$100.
The RS stock number is 383-9435. The unit can be purchased from RS Components over the
phone using a credit card on 1300 656 636.
The Under Voltage Alarm
The circuitry in the control box has been designed to let the user know when battery life is
low. If the voltage falls bellow 11 volts, the red power light on the face of the control box will
start to flash signaling a possible decline in performance.
Note - The Panel Reader does not contain a power on/off switch. When a power source is
connected to the Panel Reader it will commence immediate operation. When powered from a
battery source, be sure to disconnect the battery when the Panel Reader is not in use in order
to conserve battery life.
Note - The Panel Reader is polarity protected against accidental reverse voltage application
and will not be damaged by such. However, reversing the power connections will prevent the
Panel Reader’s operation.
Rev Australasia V2.3 12/04
Serial Data Communications
The Panel Reader is provided with RS232 serial communications interfaces. RS232 is
generally used in short run (less than 15 meters/50 feet) configurations where the data
recording equipment is provided with a compatible RS232 interface. Longer cable lengths are
possible also when data communications rates are low (9600 bits/second and lower). A
standard 5 metre cable is provided.
When long cable lengths are required between the Panel Reader and the data recording
equipment, when data communications rates greater than 9600 bits/second are being used, or
when bus communications are being used, the Panel Reader’s RS422/RS485 option should be
discussed with Allflex.
Note - Serial communications for all interfaces are half duplex – that is, communication
exists both to and from the Panel Reader, but not simultaneously. While ID Code data is
being transmitted from the Panel Reader, communications to the Panel Reader cannot be
received simultaneously.
Note - RS232 and RS422/RS485 interfaces are concurrently enabled but only RS 232 is
wired to the connector on the control box. At all times, the Panel Reader can receive
commands through either interface. However, both interfaces are coupled to a single receive
input pin on the Panel Reader’s internal circuitry. Consequently, if inputs are applied
simultaneously on both RS232 and RS422/RS485 interfaces, the commands will collide and
be unrecognizable to the Panel Reader. The user should employ only one of the interfaces for
sending commands to the Panel Reader.
Note - Both RS232 and RS422/RS485 outputs can be simultaneously used. For example,
the RS232 output could be connected to a weigh-scale and the RS422 output could be
connected to a data recording device. Only one of these two user equipments should,
however, have its transmit output connected to the Panel Reader’s receive input, as is
explained earlier.
RS232 Serial Data Interface
The RS232 serial data interface comprises a 3-wire arrangement, consisting of transmit
(TxD), receive (RxD), and ground (GND). This interface can be configured for a variety of
communications parameters, but is factory configured with default settings of 9600
bits/second, no parity, 8 bits, and 1 stop bit (“9600N81”), and no flow control. To determine
the required settings, refer to the interface requirements for the data recording application that
is being used with the Panel Reader. To change these default settings, please see
“Configuration Options” section.
Serial data appears on the Panel Reader’s TxD connection in ASCII format, and is compatible
with most PC terminal emulator programs, such as HyperTerminal®. Configuration options
provide flexible formatting of transponder ID code information (see “Configuration
Options”). The default formats for ISO transponder tag types are listed in Table 2 on page 2
of this guide.
RS422/RS485 Serial Data Interface
The Panel Reader’s RS422/RS485 is not wired from the circuit board unless specifically
required. RS422/485 serial data interface comprises a balanced 4-wire (RS422) or balanced
2-wire (RS485) arrangement, which is capable of being used in any of several wiring
Rev Australasia V2.3 12/04
configurations. The balanced nature of this interface provides the ability to achieve long data
communications cable lengths of up to 1500 meters (5000 feet) at the maximum
communications data rate of 57,600 bits/second.
An excellent technical guide to RS422/RS485 communications can be found on, and
downloaded from, B&B Electronics’ Internet web-site at:
Users who are planning to connect several Panel Readers on an RS422/RS485 bus should
consult Allflex.
Performance Verification
Using several test eartags of the types to be used with the Panel Reader, the user can verify
read range and read zone area of the installed system by using the green light and beeper as an
indication of when the Panel Reader is correctly reading the eartags. Under optimum
conditions the read ranges listed in Table 4 are typical expected performances.

Medium Panel Antenna

Among many influences, the read distance performance of the Panel Reader will be affected
by the following:
Eartag Orientation - For maximum reading distance, the axis of the eartag and reader
antenna coils must be optimally oriented (see Figure 5).
Eartag Quality - Each manufacturer’s eartag differs in (a) the amount of exciter signal
energy necessary to sufficiently operate the eartag’s internal circuitry, and (b) the signal level
of the ID Code information that is returned to the reader. Consequently, it is normal for
eartags of a common type (FDX-B, for example) made by different manufacturers to exhibit
different read range performance characteristics.
Eartag Motion - The Panel Readers have different size antennas, and the smaller antennas
produce smaller effective “read zones”. Panel Readers are generally designed for reading
eartags while in motion, both translating and rotational. An eartag that is moving quickly
through the read zone while simultaneously changing orientation may not be present within
the reader’s read zone sufficiently long for all the ID Code information to be obtained.
Eartag Size - Physically larger eartags generally contain larger antenna coils which produce
longer reading distances than smaller eartags having small antenna coils.
Eartag Type - HDX eartags (NLIS type tags) generally exhibit greater reading distances than
FDX-B (Small Stock ) eartags of comparable size.
Proximal Metallic Objects - Metal objects located near the eartag or Reader can attenuate
and distort the electromagnetic fields generated in RFID systems, and thus diminish read
distance performance.
Electrical Noise Interference - RFID eartags and readers use electromagnetic signals as a
premise of operation. Other electromagnetic phenomena, radiated electrical noise from
Rev Australasia V2.3 12/04
computer displays, for example, can interfere with the transmission and reception of RFID
signals, and consequently reduce reading distance.
Eartag/Reader Interference - Multiple eartags within the sensing range of the reader, or other
readers emitting excitation energy in the immediate vicinity can adversely affect the reading
performance or prevent operation of the Panel Reader.
Panel Reader Read Zone Geometry
The read zone is the 3-dimensional space within which an eartag can be read when held in a
static and optimum orientation. Figure 5 approximates the Panel Reader’s read zone in a 2dimension perspective, as viewed from either the side or top, and illustrates eartag orientation
for maximum and null reading. Optimum read distance is achieved when the Panel Reader’s
magnetic field lines intersect the surface of the eartag perpendicularly. More practicably, the
eartag’s read range is maximized when the eartag’s axis is perpendicular to the midpoint of
the Panel Reader’s flat surface. As the eartag is shifted from midpoint toward an edge of the
Panel Reader, maximum read distance is usually achieved by tilting the eartag so as to
maintain perpendicularity with the magnetic field lines as shown in the diagram below.

Interpreting Tag ID Code Information
Table 2 lists the default data formats that are transmitted from the Panel Reader’s serial
communications port, in response to reading compatible type tags. For ISO type tags, there is
no difference between HDX and FDX-B outputs. Both types of tags produce a default
where the underscore “_” represents a space character, and <CR><LF> is a carriage return
/line feed (unprinted control characters which cause a PC’s display cursor to jump to the
beginning of the next line prior to displaying the next ID number).
In the above data output, the prefix “LA” represents “line mode – animal coded read only
tag”, “982” is the Allflex manufacturer number assigned by ICAR, and the last 12 digits
comprise a unique number sequence for this particular transponder.
The TIRIS S2000 output format has become a de facto standard for many users, and appends
the reserved field and data block bits contained in the ISO coded eartag to the Panel Reader’s
default format, causing the ID code information to appear in the format:
This output is easily configured using either the Configurator® utility, or by issuing the
Command “BE40239” to the Panel Reader (see “Configuration Options”).
Note - The manufacturer code “982” will be different for another manufacturer’s tag, and
can also be replaced by an ISO country code (“250” = France, for example). When other
manufacturer codes or country codes exist, there can exist the same 12 digit ID number.
Note - While HDX and FDX-B type transponders have an identical context, they are
guaranteed by Allflex to be unique. That is, HDX tag type ID numbers are never duplicated
in FDX-B type tags.
For HDX Industrial coded tags, the output format is:
In this tag format, the prefix “LR” represents “line mode – industrial coded read only tag”,
“0006” is an application code unique to Allflex, and the last 16 digits comprise a unique
identifying number sequence.

Panel Reader Configurator®
The Panel Reader is shipped with this Installation Guide and a CD copy of a PC Microsoft
Windows® compatible application program Configurator®. Configurator® is an easy to use
utility that aids in changing the factory set default options in the event the user wishes to
customize the behavior of the Reader and the ID number format. Configurator® is a selfinstalling program. Usually you should
not need to change the factory default

Once the Configurator® is
installed, connect your antenna to
your computer using the serial
communications cable supplied.
Connect the cable between your
antenna control box and to a free
serial port on your computer.
Power up the antenna. Start the
Configurator® program by double
clicking on the Configurator® icon
on your desktop.
Select the appropriate PC COM port at the top of the screen, and Configurator® will
automatically poll the serial port, identify the Panel Reader, and display the current
Rev Australasia V2.3 12/04
configuration settings. Configurator® comprises a single window display within which all
options are listed and all possible settings are viewable in drop-down menu boxes.
The Configurator® program will automatically determine the communications settings that
are effective in the Panel Reader. The factory default settings are 9600 bits/second, no parity,
8 bits/word, 1 stop bit, and no flow control. If these parameters are changed by the user, these
settings will be automatically detected by Configurator®.
The settings should automatically appear
from the reader in the boxes of the
program. However, if not – select the
GET SETTINGS icon or select the
READER button and the then GET
SETTINGS (F2 Key). This will bring the
settings into the program.
After the settings have been brought into
the Configurator® Program, make the
appropriate changes you desire. Then you
will need to apply these settings. To do
this, select the APPLY SETTING icon, or
select READER and then APPLY SETTINGS or press the F3 key.
A typical example of where changing a setting might be necessary is to change the reader so
that it sends duplicates, or perhaps, not to send duplicate reads. This means that if a beast gets
read 20 times as it walks past an antenna, the reader will transmit the number 20 times to the
computer / scale head. Some scale heads are set for this such as the Trutest XR and SR series.
Some other brands such as the Ruddweigh 500 and 600 series require the number once only.
Therefore, in Australia and New Zealand, the Factory Default Settings are changed just in
case the reader will be connected to a Ruddweigh system. This means that the Send
Duplicates function is set to “Don’t Send’
If you have to change this setting, or if your panel gets accidentally set back to factory default
settings, you can change the Send

the configuration setting process, but will interfere with any performance measurements the
user might wish to make.
Configuration Options
In addition to using the Allflex Configurator program, configuration options can also be set
using alphanumeric commands from a PC terminal emulator program, such as Microsoft
Windows HyperTerminal®, or from a user proprietary program that is capable of similar
communications, using the Panel Reader Serial Command Language.
Serial Command Language Method - Basic Instructions
The following instructions describe some of the basic and more frequently used configuration
options, and illustrates how to implement them using the Panel Reader Serial Command
Language in conjunction with HyperTerminal®. The Command Language method uses
upper and lower case alpha characters combined with hexadecimal characters to establish the

Panel Reader Tuning
The Panel Reader is factory tuned for optimum performance in the absence of nearby metallic
objects. In some mechanical installations, mounting the panel reader near stationary metal
objects is unavoidable, and sometimes it becomes necessary to install metal shields behind the
Panel Reader in order to limit its effective read zone. In these instances, the presence of metal
can detune the Panel Reader’s antenna circuit, and compromise performance. The easiest way
to determine this is to simply measure the Panel Reader’s reading distance with and without
metallic object’s present.
When it has been determined that a metal object does compromise the read distance
performance, it may be possible to retune the Panel Reader. In order to do this, please refer to
the separate tuning document supplied with your reader.
Panel Reader Synchronization
Please consult Allflex before attempting synchronization. When multiple Panel Readers are
installed nearby one another, in some instances there may be mutual interference induced
among them due to their independent exciter signal timing. If Panel Reader performance is
compromised or inhibited when a second Panel Reader is activated, the user should employ
the wired synchronization option. In order to synchronize the control boxes for both readers
must be upgraded to include a synchronization board. Both boxes then need to ne joined
using a specific cable. One reader unit must be configured as a master unit, and all others
must be configured as slave units, using Configurator®. Detailed instructions must be
sought from Allflex for the synchronization option.

Assuming that the reader has been successfully installed and commissioned, generally,
reliability issues with any sort of RFID reader will fall into 2 categories. (a) Poor read / No
read and (b) No Communications. Please see following a flow chart that will assist in
diagnosing faults.
(a) Poor Read / No Read. If the panel reader has been in use and working previously and
then unexpectedly starts performing in a less than satisfactory manner, the likely
causes are
(1) Power Supply Problems
(2) New Equipment interference.
Firstly, test the power supply (battery etc). As an automotive battery loses charge
from close to 14 volts, the antenna performance will remain reasonably constant but
fall away badly at about 7 or 8 volts. So the first point to look at relating to reader
performance should always be power first. If you have tested the battery and know
that it is well charged then look at issues such as;
• Has any new electronic equipment been added close by or connected to the reader?
Such as a power supplies for radios, new scale heads, computers, computer
monitors etc? If so – switch them off and retest performance.
• Is there a problem with your AC power? In some cases it is possible for the earth
voltage (which should be zero) to actually float. When you plug in a computer, or
scale head to a panel reader, the high earth voltage is transferred to the
microprocessor in the reader. This causes the reader electronics to lock up.
(b) No Communications. This would mean that the reader can actually be seen to read a
tag, in that the reader beeps, the lights flash etc, but the electronic number is not
appearing on the scale display, or computer screen.
Communications is the process of transferring the RFID device number (and other
data) between the reader and the scale head, or computer. You may hear terms like
“Serial Communications” or “Comms” or “Serial Data”. All these terms refer to the
data being linked from the reader to the attached technology (Scale head, computer
It is very uncommon for the serial communications ports to stop working on, either the
reader, scale head or computer. The most common issues that prevent data from being
transferred will be
(1) Broken cable that joins the reader to the scale / computer etc.
(2) Incorrect port / communication settings. These settings can sometimes be
altered in both, the reader, scales or computers. The settings include issues
like, baud rate, parity, flow control etc.
Baud rate is the speed at which the “bits” of data are sent down the wires. If
baud rate and most of the other setting are not matched at both ends (reader
and scale /computer) the data will not be sent.
The standard settings for the Allflex Panel Reader is 9600 baud rate, 8 Data
Bits, No Parity, 1 Stop Bit and No Flow Control. These settings can be
checked and changed for the panel reader by using the Configurator ©
program described earlier.
Rev Australasia V2.3 12/04
Testing Communications
You can prove that the reader is communicating by plugging the reader into your computer,
powering it up (reader and computer) and starting up the Configurator © program. The
settings should automatically appear in the Configurator © screen. If not select the option to
“Get Settings”.
If the data does not appear it is likely that there is a problem with the communications. This
might suggest that the Receive Wire is broken. Try reading a tag. The number should appear
at the bottom of the screen. If it does, this would tend to confirm that it is possible that 1 wire
(the Receive wire) from the Control Box might be broken. IE it can send data out but not
receive data. The fact that the tag number has been received in the Configurator © would
show that the reader is transmitting data. In this case, the reader will still work fine with most
scale heads and computer programs, but you will not be able to change any settings using
Configurator® program.
If you connect the Configurator © program and the nothing appears on the screen and a tag
number doesn’t show up after being read, it would suggest that there may be a problem with
the Transmit wire. In this case, it would be advisable to close Configurator © program and
try another program. Also if you don’t have Configurator © program, there is another
program called HyperTerminal © that comes installed as standard on most computers . You
can also use this to test communications.
Note: you cannot operate Configurator ©, HyperTerminal ©, or any other software that uses
the serial ports on your computer simultaneously. That means you can only have one program
open at once.
Using HyperTerminal ©
. In most computers you can find the HyperTerminal © program by clicking on Start, then
Programs, then Accessories, Then Communications, then HyperTerminal.
Rev Australasia V2.3 12/04
The following screen will appear when HyperTerminal © starts. In the Name Box, enter some
name like TEST, etc then click OK.
When the following screen appears. Select, the pull down arrow in the “Connect Using” and
select the appropriate Com port on your computer (usually Com1) and then click OK.
Then the properties window will appear. Change the Bits per seconds (Baud Rate) to 9600,
the Data Bits to 8, the Parity to None, Stop bits 1 and Flow Control to None. Then click OK.
Rev Australasia V2.3 12/04
Then a blank Screen appears. To test if you can send information to the reader – Hold down
the SHIFT key and press the letter “p”. A capital P should appear and then followed by data
gathered from the panel reader, similar to that shown below.
When you scan a tag, the number should now appear.
Rev Australasia V2.3 12/04
Now we know that the panel reader is both reading and communicating effectively. This test
proves that the cable is also functioning. The P signal means that the PC is communicating
with the Reader and the returned Tag ID means that the reader is communicating with the PC.
You should then check other equipment such as the scale head or computer to confirm they
are operating correctly.
Testing a Cable with a Multi-Meter
A useful test tool to have available is a Multi-Meter. In particular, a model that can measure
DC volts and ideally has an audible continuity (Ohms) selection. Multi-meters can be
purchased from electronics stores and can range in price from $10 upwards. If you were
anticipating buying a multi-meter to use specifically for this equipment, a cheap unit around
$10 - $30 will be sufficient.
If you have tested the communications using HyperTerminal © or Configurator © and
suspect that the cable may be damaged you can use a multi-meter to test for broken wires.
Standard communications cables as used for the Panel Reader, are based upon 3 wires.
These wires are Signal Ground, Transmit and Receive. The cable provided has a 9 pin
female D connector on one end and a 4 pin male military connector on the other. (As shown
in the picture below).
The D connector is marked with numbers 1 through to 9 and the military with letters A, B,
C & D.
Rev Australasia V2.3 12/04
The table below shows how the cables should connect from one end to the other.

Transmit (TxD)
Receive (RxD)
Signal Ground (GND)
Pin A
Pin B
Pin D
Pin C (not used)
9 pin D Connector
Pin 2
Pin 3
Pin 5
You can test these connections using the Multi-meter.
On the dial of the meter select the Ω
scale. If your meter has an audible
beeper, select that setting, if not select the
lowest value in the scale.
Insert the test leads into the meter, the
Black lead connects to the COM socket
and the Red lead connects to the socket
showing the Ω Omega symbol.
To see how the meter should
work – touch the two test leads
together and you will hear the
beeper sound (if your meter has a
beeper) and the screen, or dial
will go from open circuit to short
circuit (zero ohms).
Twist a paper clip around the end
of one test lead. Then insert the
paper clip into Pin 2 on the D connector. From the table above, you can see that Pin 2
Rev Australasia V2.3 12/04
should connect to Pin A on the military connector. Therefore touch the second test lead
against Pin 2, if the cable is correctly joined you will hear the meter beep and see the dial or
display show zero, or almost zero ohms.
Use the table above and use the same process to also check the connections for Pin 3 and
Pin 5 on the D connector and ensure that the cable is not broken. If you test any of the 3
wires and find that they do not connect, you should use a replacement cable, or, open the
military connector and re-solder any wires that you can see have become detached.
If you can see the cable is broken at some point in the centre, you can make a temporary
repair by stripping back the 3 relevant wires, twisting each one together separately and
sealing with insulation tape. You will know what coloured wires to join by opening up the
military connector and seeing the 3 wires that terminate. (As a standard Allflex usually uses
White, Green and Yellow).
Apart from the cable breaking (open circuit), it could happen that the cable gets exposed to
direct rain and that water is shorting out some of the pins. To test this, insert the paper clip
to Pin 2 and then test to Pin A, B and D on the other end. As you see from the table above,
the cables should only join from one point on one end and to a specific point on the other
end. If you notice that there is a join between multiple points this indicates that there is a
short circuit. Open the military connector and see if it has water inside and spray with water
dispersant spray if required.
Rev Australasia V2.3 12/04
Testing If A Battery Is Charged And Working.
As mentioned a Multi-Meter can also measure voltage. If the reader is performing below
standard you can check the battery voltage by following these steps. Insert the black test
lead into the socket on the meter called Com. Insert the Red test lead into the socket that has
the V shown. On the selector switch, select DC Volts and the 20 volts scale. This may be
shown as V== (as opposed to AC volts which might be shown V~)
Hold the black test lead against
the negative (-) terminal on the
battery and the red test lead
against the positive terminal (+)
on the battery. If the meter shown
less that 10 volts, you should
consider recharging or swapping
the battery.

3.2.13. Re-Send Last Tag
In case port type is set to RS232 the reader re-sends last tag read according to the
currently selected ID-Code format settings. In serial bus mode, where port type is set
to either RS422 or RS485, the reader transmits the first read result stored in the ID
code buffer out the serial port, according to the currently selected ID-Code format
settings8. This way the readers can be polled to request tag data from the readers
connected to the bus, as the readers using serial bus mode then do not automatically
send tag data upon successful detection.

4. Bus Protocol
Serial bus communication is active when serial port type is set to either RS422 or RS485.
The reader accepts in this mode framed as well as unframed (RS232 port type typical, as
described in section 3. ASCII protocol) commands. Readers responses to both framed and
unframed received commands are always framed.
Up to 32 readers can be addressed on the bus. Therefore each reader on the bus has to have
a unique bus address assigned! The Allflex Panel Reader does not respond to received
frames containing a different address than the own!
The data part of the framed message is equal to the ASCII protocol described in section 3.
Commands can be issued enclosed in the frame.
The reader in bus mode does not automatically send tag reading results! These are
temporarily stored in ID code buffer and can be requested by use of the command r
(described in section 3.2.13.). This command requests the first ID code stored and clears
the record upon transmission. The first tag data will be overwritten with new tag data once
the buffer is full without indication.
Command responses in bus mode lack initial and ending carriage return and line feed
4.1. Framing
The Allflex Panel reader uses a simple framing. Each message begins with SOH (02h),
followed by the binary reader address14, a STX (03h), the data and as the terminating
character an EOT (04h).
<SOH><ADDR><STX>< .. DATA .. ><EOT>

+-----------> Data, as described in section 3. ASCII protocol
| | +---------------------> Start of Text (03h)

+-----------------------------------> Start of Heading (02h)
Please see section 3.2.11. on how to change the serial
bus address.
