2 System overview
The SR3000 is a Stationary Reader for ISO 11784/11785 transponders with very good
reading performance thanks to its dedicated RFID DSP-processor and auto-tuning
function. It comes with a range of panel antennas and can read and control two inputs
and two outputs. It is therefore ideally equipped for integration by System Integrators
and OEM’s.
Figure 2.1 shows an overview of an SR 3000 Single Reader configuration system which
consists of
• Stationary Reader (SR3000),
• Antenna (SA SR3000)
• Power Supply (PS SR3000).
The PC is optional and is no required for a working system.
The SR3000 is installed in an IP 65 enclosure with clear RFID indicator lights. A simple
communication protocol sets and reads the I/O’s and can also switch on/off the HF-field.
The integrated auto-tuning warrants optimum identification in dynamic environments,
even when the antenna environment changes due to (unexpected) external
circumstances. The DSP-algorithm is fine-tuned for optimum RFID performance with both
FDX-B and HDX transponders.

3 Installation
3.1
Antenna installation guidelines
To get a reliable identification of animals passing the stationary reader antenna,
a ‘safety area’ outside the antenna must be respected. Inside this area metalreinforced building structures or other metal equipment short-circuiting the
antenna electromagnetic field are not allowed.
By following the guidelines set out in this chapter, you will be able to cover most
installation requirements to achieve maximum performance of the SR3000.

3.2
The antenna wire used has proven to be water resistant and can be exposed
to water.
Use the pre drilled holes on the antenna for mounting.
Do not mount the antenna in direct sunlight.
Mount the antenna on a non conductive material (e.g. plywood, concrete,
etc.).
If mounted on a concrete wall, make sure the wall does not contain any
metal reinforcement.
Metal in proximity of the antenna (e.g. fences, pipes and metal loops) will
cause damping or detuning and the reader system will have lower
performance.
Do not cut the antenna wire to make it shorter. This will cause detuning.
Roll-up unneeded antenna wire.
Make sure that antenna wire is properly fixed so it can not move. If the
antenna wire has physical movement then this can reduce the performance.
Power supply
Power supply is a critical factor in RFID. For best RFID performance use
ONLY original BioControl PS SR3000 power supply or car battery.
The Stationary reader requires +13,2V DC stabilized power. It can also be
connected to a car battery.
Current consumption varies with the type of antenna which is used.
•
Medium size antenna (600x400mm): current consumption is less than 1A.
•
Large size antenna (1500x600mm): current consumption is less than 1.5A.
Note: Mount PS SR3000 Power Supply minimum 1 meter away from SR3000
and antenna!

3.4.3 Connecting the antenna wire
Pull the antenna wire through the grommets according to table 3.1 and then
through the ferrite (see picture below) to antenna connector X20. Endings of the
antennas should be screwed tight in the connector. The ferrite should be used
for EMC- reasons.
Figure 3.5: Ferrite with bracket
Warning! Do not touch the antenna connector X20 - as they are charged and
could give you an electric shock. Always switch off the power before opening the
box
3.4.4 Connecting the LIYCY reader synchronization cable
When using more then one SR3000, ON/OFF synchronization of the HF-field is
essential because two or more antennas are active with a relative small distance
between them. For this reason, each SR3000 unit contains a synchronization
terminal. HF-synchronization requires one master which triggers the HF-field of
one or more slaves.
The electronics handling the synchronization is a standard RS485 industrial
communication bus. It is capable to handle maximum length of 1000 meters.
Use the cable LIYCY 2*2*0.25mm. (or equivalent). LIYCY is a low cost standard
signal cable and the recommended one for the reader synchronization. It
consists of 2 pairs or independent twisted wires in a shielded cable. It is used for
its robustness against electric and magnetic disturbances.
If two readers are used then connect them the following one to one connection.

Set/configuration
3.5.1 Set/configuration of Node Address
The node address on the SR3000 must be set both when used as RS232 (Single
Reader Configuration) and RS485 (Single and Multiple Reader Configuration).
The 4 first micro switches on X23 set the node address. In the table below a “1”
indicates that the switch is ON, “0” indicates that the switch is OFF. “X” indicates
that the position of it is not relevant to setting the node address.

Note: configuration of node address is set independent of master / slave

3.5.2 Set/configuration of master and slave
(Multiple Reader configuration)
When SR3000’s are installed close to each other, then the HF-field must be
synchronized. As a rule of thumb for the SR3000, when using Medium or Large
antenna, the readers must be synchronized if they are closer than 50 meters
from each other. This distance mainly depends on the amount of interference
between the readers. The amount of interference depends of field strength
generated the antennas, the amount of metal shielding in the surroundings and
the angle of the antennas in relation to each other.
Mar-2009
Page 12 of 37
D02C1.0 SR3000
In a system like this there must always be only one master. It does not matter
where the master is. The rest are slaves. There can be many slaves. End resistor
must be set for first and last SR3000. An end resistor is necessary for error free
bus communication. Example to connect max 16 readers is below.
Figure 3.6: Multiple Reader configuration
Note: For each node, two settings must be made:
- Set master or slave (X11).
- Set end resistor or not for synchronization (X24/7).
- Set end resistor or not for RS 485 communication (X24/8).

4 Operation
4.1
4.2
Instructions for proper installation and operation
•
It is important to plan the lay-out of the installation such that only one
animal at the time is picked up by the stationary reader antenna.
•
Each animal that passes the antenna must wear a good-functioning FDX-B
or HDX transponders.
•
Ear transponders should always be attached on the same side of the animal,
either right or left ear. Mount the panel antenna on this side.
•
If any new animals are introduced, always check that the transponder is
placed on the same side as for the rest of your herd.
•
Shield/direct the animal traffic such that the antenna can not pick-up
transponders of other animals unintentionally.
•
Ensure that no conductive materials are close to the antenna.
•
Do not direct high pressure cleaner directly towards the SR3000 housing.
•
Don’t change antenna cable length. If too long: roll -up!
•
Install Power Supply minimum 1 meter away from Stationary Reader and
Antenna!
•
Cables should be placed so that they will not be walked on, chewed by
animals or squashed in any way.
Adjust Antenna – auto tuning
The SR3000 has auto tuning to achieve optimum reading performance. This is a
mechanism in the reader that adapts the reader to the antenna. It has two kinds
of auto tuning.
Mar-2009
•
First auto tuning is during the first 5 seconds after power up. It is indicated
by the three lower LED’s and the charge HF LED. During tuning the three
lower LED’s are on and the HF LED is blinking very fast. This tuning is done
to adapt the reader to the connected antenna. This is done because of
component tolerances, antenna tolerances and the fact that some metal will
always be in proximity of the antenna.
•
Second auto tuning is done continuously to cope with changing ambient and
circuit board temperatures. This ensures optimum performance.
Page 16 of 37
D02C1.0 SR3000
4.2.1 Indication of not correct tuned antenna:
The reader and the antenna can be detuned in two ways
1.
If the antenna inductance is lower than the tuning window can
cope with, then the three indicated LED’s blink 10 times after
auto tuning. Reason can be too much steel is in the proximity of
the antenna or the antenna or the reader can be broken. It can
also be as simple as loose antenna terminals.
2.
The AUX LED blinks 10 times after auto tuning. Then the
antenna inductance is higher than the tuning window can cope
with.

5 I/O configuration
The SR3000 is equipped with standardized computer interface to suit both RS232
interface with a PC or other serial device, as well as addressable interface on a RS485
field bus.
The second RS485 is used for Master/Slave synchronization with optical isolation.
The 2 inputs are equipped with pull-up resistors and can be used e.g. for detecting a gate
switch or photo cell.
Figure 5.1: Input (1k pull-up resistor)
The 2 solid state outputs can be used e.g. to operate relays or actuators.

8 Trouble shooting guidelines
Problem
Metal pipes are placed
where I want the antenna
to be.
One reader installation
performs
worse
than
another installation.
-
-
-
-
-
-
-
-
On one reader the Power
LED and the Charge LED
are always on. It does not
read transponders.
Mar-2009
Solution
Cut away metal pipes. Mount the antenna
on wood, plastic or other non conductive
material.
Make sure that all animals have only one ISO
transponder.
Best performance is achieved if all the
transponders are on the side of the animal
which is closest to the antenna panel.
Check that transponders have stable reading.
To do this the transponder must be removed
from the animal, tested in front of the
antenna and compared with a good
transponder.
Sometimes HDX and FDX can have reduced
performance. This will happen if the
transponder is physically damaged or is
extreme noises environment.
Check that there is no metal in proximity of
the reader that can have mechanical
vibrations (especially for FDX-B).
Check that power supply is +13,2V DC.
Having a powerful and stable +13,2V DC
power ensures a well working system
otherwise use battery
Check that antenna wires are not damaged.
Retighten antenna wires on terminal X20.
Check that antenna is tuned. Restart the
board while looking at the LED’s. Make sure
that no steel work is added or removed in the
proximity of the antenna after reader is
tuned.
Check that protected earth, PE, is connected
from pin 14 to the main fuse board.
If other stationary readers are in the same
area then they must be synchronized.
If synchronization is not possible then an
absolute minimum distance of 50meters must
be
respected
between
unsynchronized
equipment.
Check that protected earth, PE, is working.
Earth
problems
can
cause
worse
performance. Contact electrician.
The reader is in Slave mode and the
connection to the master is not working.
Page 31 of 37
D02C1.0 SR3000
Sometimes the reader
performs
really
badly.
There is a motor with a
variable
speed
drive
nearby.
The variable speed drive must be installed correct for
it not to generate too much RF interference.
Following must be checked on the variable speed
drive:
- Shielded power cables
- Shielded control cables
- Shielding connected all the way from control
panel to speed drive and to motor cables.
- Protected earth connected all the way from
main fuse board to speed drive and further to
motor and control panel.
- Main power filters between main supply and
variable speed drive.
Low
performance
on
transponders. There is a
monitor with CRT tube
very close to the reader.
Install monitor according to CE e.g. a flat
screen monitor instead. They generate less
magnetic field disturbance.
The antenna wires are
open. I am afraid that
moisture can damage it.
The antennas are designed to cope with
moisture and direct hosing.
Several animals can have
the transponder in the
antenna field at the same
time.
One animal has two
transponders. One is a
FDX neck implant and the
other is a HDX ear tag.
This seems to cause
problems.
Power supply LED is off
The reader worked well
when I installed it, but
one year later reading is
not as good.
Mar-2009
This must be solved by having a narrower
ally where the animals pass.
FDX and HDX can be read at the same time.
Only solution is to remove one of the
transponders.
Make sure that the board has +13,2V DC.
If the SR3000 is installed in an environment
where vibrations occur, then all terminals
must be tightened once in a while. The
antenna terminal X20 is the most critical
one. Loose antenna wires will have bigger
impact on detection of FDX than on HDX
transponders.

BioControl Transponder Logger program
The Transponder Logger is a simple PC-program that displays the current transponder
number and stores it in a file with date/time stamp. The Transponder Logger program
can be downloaded from the ‘Community’ section on the BioControl website.
Figure A1.1: Transponder Logger program overview
Steps to follow:
1.
Turn on the SR3000 and connect it to the PC with the RS232 or RS485 cable
2.
Download and run the latest version of Transponder Logger
3.
Select Communication port (‘B’ field) where the SR3000 is connected
4.
Select Log file location by pressing the Browse button beneath “A” field, default
is “C:\Program Files\BioControl\SR Transponder Logger\data\”
5.
The log file name is generated from the date, for today the name will become:
BC DD-MM-YYYY.csv (e.g. BC 20-01-2009.csv)
6.
The program will create the log-file automatically
7.
Field “C” shows current transponder number
The log file is a standard text file with csv-extension, which is automatically opened by
Excel. The two fields are separated by semicolons.
When opened in a text file editor like Notepad, the file will look like this:
Figure A1.2: Log file opened in the Notepad
Mar-2009
Page 35 of 37
D02C1.0 SR3000
When opened in Excel (automatically opened by double-clicking the file):
Figure A1.3: Log file opened in Excel
Column A must be widened to show the time and date correctly:
Figure A1.4: Widen column A
Then column B must be formatted as a number without decimals to show all the digits of
the transponder:
Figure A1.5: Format column B
The number is a copy of what the SR sends on RS232 or RS485. Excel does not
display/store leading zero’s in the transponder number.
Note: SR3000 must be setup into decimal mode for this (default setup after power up)
