optique raccordé à une sortie optique.
WARNING
This device is shipped with default passwords.
Default passwords should be changed to
private passwords at installation. Failure to
change each default password to a private
password may allow unauthorized access. SEL
shall not be responsible for any damage
resulting from unauthorized access.
AVERTISSEMENT
Cet appareil est expédié avec des mots de
passe par défaut. A l’installation, les mots de
passe par défaut devront être changés pour
des mots de passe confidentiels. Dans le cas
contraire, un accés non-autorisé á l’équipement
peut être possible. SEL décline toute
responsabilité pour tout dommage résultant de
cet accés non-autorisé.
CAUTION
Although the power level is low, concentrated
energy from a directional antenna may pose a
health hazard. Do not allow users to come
closer than 34 cm (14 in) to the antenna when
the transmitter is operating in indoor or
outdoor environments in the 900-MHz band.
ATTENTION
Bien que le niveau de puissance soit bas,
l'énergie concentrée d'une antenne
directionnelle peut être un danger pour la
santé. Ne pas autoriser les usagers à
s'approcher à moins de 34 cm (14 po) de
l'antenne quand l'émetteur est en opération
dans un environnement intérieur ou extérieur
dans la bande des 900-MHz.
CAUTION
The radio contains devices sensitive to
electrostatic discharge (ESD). Undetectable
permanent damage can result if you do not use
proper ESD procedures. Ground yourself, your
work surface, and this equipment before
removing any cover from this equipment. If
your facility is not equipped to work with these
components, contact SEL about returning this
device and related SEL equipment for service.
ATTENTION
La radio contient des circuits sensibles aux
décharges électrostatiques (DES). Des
dommages permanents non-décelables
peuvent résulter de l’absence de précautions
contre les DES. Raccordez-vous correctement à
la terre, ainsi que la surface de travail et
l’appareil avant d’en retirer un panneau. Si vous
n’êtes pas équipés pour travailler avec ce type
de composants, contacter SEL afin de
retourner l’appareil pour un service en usine.

Section 1
Introduction and Overview
Overview
The SEL-3031 is a 900-MHz, license-free, spread-spectrum radio. The radio operates
in the ITU Region 2 ISM band of 902–928 MHz through the use of a fast frequency-
hopping algorithm for noise immunity and long-distance operation.
The SEL-3031 prevents the need for multiple sets of radios or expensive dedicated
fiber transmitting over long distances. Figure 1.1 shows the flexibility of the SEL-3031
in providing DNP3 SCADA information, MIRRORED BITS®control for reclosing
coordination, and engineering access to the SEL-651R Recloser Control.
Figure 1.1 Point-to-Point Product Overview
Figure 1.2 shows the flexibility obtained when using the SEL-3031 in point-to-
multipoint (P2MP) applications providing DNP3 or Modbus SCADA information from
many remotes to one master.

Figure 1.2 Point-to-Multipoint Product Overview
Features, Benefits, and Applications
➤Dual Radio Operating Modes Provide Flexibility. Supports
point-to-point (P2P) radio operation for fast teleprotection,
distribution automation, distributed generation, and economical
backup protection. Apply point-to-multipoint (P2MP) radio operation
for SCADA and other data-gathering from remote locations.
➤Three Ports in One Radio Reduce Costs. Simultaneously
communicates with as many as three independent ports and protocols
via point-to-point radio operation.
➤Low Latency Enables Fast Control. Transfers control commands
with a typical 4.8 ms latency with SEL MIRRORED BITS®
communications.
➤Strong Security Thwarts Attackers. Protects critical data and repels
malicious attacks with optional encryption card, using session
authentication and strong 256-bit Advanced Encryption Standard
(AES) technology.
➤Tough Radio Operates in Extreme Conditions. Is designed, built,
and tested for trouble-free operation in extreme temperature,
electromagnetic interference, shock, and vibration conditions.
➤No Licensing Reduces Delays and Expenses. Uses the license-free,
900-MHz ISM band for on-time, on-budget projects.
➤Mounting Options Simplify Installation. Order your SEL-3031 in
either a rack-mount or wall-mount form factor.
