Mechanic:
Antenna: Dimensions: 408 x 288 mm – Thickness 13 mm
Electronic case: Black PS choc IP65
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:
•Informatics data transmission cables
•Energy transmission cables
•Screen display
•Equipment with no EMC conformity
•Power supply units
•Variators
•Power Backups
•Detection loop

III. Calibration
First use
•Fit the reader at the desired place
•First connect the power supply – wait until the orange led has finished blinking (auto tuning
sequence) – leave no tag in the reader field
•Present a tag to the reader
•Connect the data lines –control the communication with the host system.
Auto tuning
The reader has an automatic tuning function. This automatic calibration sequence is done at every power up.
The sequence can take up to 5 seconds with the orange led blinking
Caution: No tag or card must be in the reader field during the calibration.
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
•Try to move the reader and/or change its orientation.
Caution: It is recommended to perform the test of reading by referring to the beep of the buzzer or to
the twinkling of the orange led. In certain cases, the communication with the distant system can be
faulty, letting think that the reader is not working.
TIPS: - You can use a 12V battery to power the reader and it will be easier to move it.
- 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.

Those jumpers adjust the auto tuning of the reader. For reading
distances less than 50 cm with an ISO card, it is possible to
change the configuration of those jumpers to optimize the
distances. To do that, there are four possible configurations
(
shown
below)
:
Reset the reader after each changing of configuration.

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.

-Communication parameters are:
9600 bds, no parity, CR
•Transmit the desired configuration options.
•Power off the reader.

R13 RS485 Variant 7S Protocol
Configuration mode
Warning: in this mode, the reader automatically changes its address to « FE ».
Switching to configuration mode:
•Power off the reader,
•Connect the configuration pin ("Setup") to the 0V pin. ("Ground").
•Power on the reader, the led must be orange (red + green) to indicate that it is in configuration mode. The
reader will send the following message: : STX, Address (2 characters, most significant bit first), "FECNF",
LRC, ETX.
In this mode, the reader takes the address "FE", the communication speed is 9600 bauds, no parity check
is done, the use of Carriage Return (CR) is necessary, and the reader is inactive.
•Transmit the desired options.
•Power off the reader.
•Disconnect the connection between pin “Setup” and “0v”.
