Features
?
?

Manual calibration to get the best possible performances according to the reader environment.
Possible to add an extra LED and buzzer to give detection / reading information.

Recommendations / Limits
?

If 2 (or more) readers are installed too close, it can cause a coupling. The readers will not be able to
read tags or a tag will be read by each reader at the same time.
? Do not install the reader near to a closed conductor circuit.
? Do not install the reader on a metallic support
? Do not install the reader close to a metallic ground. In this case, respect the minimum distance,
between the antenna and the ground, which are 20 cm with the side of the antenna and 50 cm with
the back of the antenna.
? Do not forget to connect the 0V to a clean ground.
(See the installation examples at the end of this document)

Unfavorable cases
Avoid installing the reader close to perturbing electromagnetic field like:

Wiring / Calibration
Wiring
Connect the power supply (0V, +12V) and the data lines to the host.
The maximum distance between the host and the reader is 100m.
Recommended cables:
1 pair 6/10° until 30 meters (98,43 ft).
2 pairs 6/10° until 60 meters (196.86 ft).
3 pairs 6/10° until 100 meters (328.10 ft).
OR
1 pair 9/10° until 50 meters (165.05 ft).
2 pairs 9/10° until 100 meters (328.10 ft).
Caution: If the HOST does not have pull up resistor on its input, it is necessary to add them on the reader.

First use
?
?
?
?
?

Fit the reader at the desired place
First connect the power supply
Present a tag to the reader
Check the good detection (if the distance is not correct, modify the calibration)
To control the detection, use the LED on the main board.
Connect the data lines

Calibration
The reader is calibrated before delivering, but it is possible that the reader need to be re-calibrated to adjust
to its environment.
?
?
?
?

Connect a voltmeter (DC) to check the consumption (see the main board view for the voltmeter
connection). Consumption = measure x 10
Usually, you get the best possible performances when the reader's consumption is maximum
(usually maximum is around 500 mA (measure 50mV)).
To correctly calibrate the reader you need to find the right capacitance value (jumper J1, J2, J3, J4
and adjustable capacitor). For more details, check the scheme and the algorithm above.
The ground jumper can be used to reduce perturbations.

Calibration algorithm

The goal of this algorithm is to find the best jumper setting by a dichotomy method.
- If the consumption increase when capacitance value is increased, the maximum
consumption value has been already reached. So you have to decrease the total
capacitance value by modifying the jumper setting.
- If the consumption decrease when capacitance value is increased, the maximum
consumption value has not been already reached. So you have to increase the total
capacitance value by modifying the jumper setting

Turn clcokwise the adjustable capacitor
(You add capacitor)

Does Reader
consumption
increases ?
YES

NO
Maximum has been reached

Maximum has not been reached

Increase the jumper setting.
You add capacitance.

Decrease the jumper setting.
You remove capacitance.

Replace the adjustable capacitor to its middle position

During the algorithm process, if you go back to the last jumper setting, it is because you are near the best
calibration setting. Try, with the adjustable capacitor, to find the maximum consumption (try it with the 2
different jumper setting).

Optimization
If you do not have the best performances, some simple tips could help you to get them.
?
?
?
?
?
?

Verify the wiring
Analyze the environment to find possible causes of perturbation
Verify that the 0V is connected to a clean ground
Measure the power supply. In some cases, the power supply doesn't succeed to drive enough
current and its voltage drop. If you have less than 12V, the performance can be reduced a lot
Measure the consumption. If you don't have around 500 mA, you need to calibrate the reader to its
environment (see the calibration section).
Try to move the reader and/or change its orientation.

TIPS: You can use a 12V battery to power the reader and it will be easier to move it.
CAUTION: All detection tests need to be done with the embedded ?CP' LED.
If you move the reader and get better performance on a new place, it means the initial place was not
compliant for long range 125 kHz readers.

Tag using
Present the tag in front of the reader, perpendicularly, and approach it slowly until the tag is detected.
It is not necessary to agitate the tag.
Caution: If the tag is inclined, the reading distance will be reduced.
