For power supply:
1 pair AWG24 for up to 30 m
2 pairs AWG24 for up to 60 m
3 pairs AWG24 for up to 100 m
Use a multi-conductor cable, pair shielded. Must be connected
to the concentrator ground. Max length: 1000 m.
3• • • • Bus characteristics
Max number of readers on the same bus: 16.
End of line resistors: R=120Ω, ¼ Watt.
These resistors must be connected on the connector of the
first and last equipment on the bus.

4• • • • 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".
•
Power on the reader so that the new configuration
parameters is active.

5• • • • Installation
•
Connect the reader
•
Test the reading and communication.
LXS: Attach the reader on the wall, or on standard electrical
flush-boxes, or on optional back part (BCK-LXS).
Install the screw caps.
Caution: Screw caps are made to be hard to remove once
installed. We recommend to make all the tests before installing
them.
AVX: Attach the reader on the wall, using the provided screws
and brass raw plugs
6• • • • Precautions for installation
•
Power supply tension at the reader's connector should be
strictly comprised between 10.5V and 15V.
•
Keep the reader away from computer or power cables as
much as possible. They can generate an electrical
perturbation that is function of their proximity and
radiation level.
•
Distance to respect between two readers: parallel plan:
30 cm – Same plan: 40 cm – Perpendicular: 25 cm.
•
If the reader is mounted on a metallic surface it can affect
the reading distance. To get the maximum reading
distance, the reader should be installed at no less than 7
cm from any metallic surface.
