The new ATL90 series Embedded PLC modem
series is based on the Direct Sequence Spread Spectrum Technology.
The new technology in Power Line Carrier (PLC) communication is well
known for its high immunity to electrical noise persistent in the
power line. With the new solution, the 
form factor of the PLC modem is further reduced and its cost
lowered.
The Embedded PLC Modem is in the form of a
ready-to-go circuit module, which is capable of transferring data
over the power cable at the low voltage end of the power transformer
of a 3-phase/ 4-wire distribution network. A pair of Embedded PLC
Modems connected on the power line can provide low speed
bi-directional data communication at a baud rate of 300/600 bps. It
is built in a small form factor that can be easily integrated into
and become part of the user's power line data communication system.
The modules provide bi-directional
half-duplex data communication over the mains of any voltage up to
250v a. c., and for frequency of 50 or 60 Hz. Data communication of
the modules is transparent to user's data terminals and protocol
independent; as a result, multiple units can be connected to the
mains without affecting the operation of the others. The use of DSSS
modulation technique ensures high noise immunity and reliable data
communication. There is no hassle of building interface circuits.
Interface to user's data devices is a simple data-in and data-out
serial link. It has a built-in on board AC coupling circuit, which
allows direct and simple connection to the mains.
Applications of the Power Line Modem
include status monitoring, control and data communication of devices
connected on the power line, such Home Automation, Lighting Control,
HVAC control, Low Speed Data Networks, Automatic Meter Reading,
Signs and Information Display, Fire and Security Alarm, ´´., and
so on.
