OVERVIEW

2.1

Signaling System

The SIG60 device is based on a unique Signaling technology. The device transmits and receives a

special signaling carrier, which can be differentiated from the Power line noise. The receiver receives

the signaling patterns at a selected frequency and extracts the data from the noisy channel into the

original bits. Multiple devices can be used as a network on any of the available carrier frequencies.

Multiple channels can operate over the same Powerline noisy lines for additional independent networks.

2.2

Channels and Network

The SIG60-SIG61 network can be set into 16 groups of frequency pairs. When set to such a pair, its two

preset frequencies can be easily switched.

Each channel can broadcast asynchronous data messages to other devices on the Power line. The

device allows the use of the LIN protocol. The SIG60 device is controlled by a host microprocessor

through its UART port.

Channel frequencies:

1.75MHz, 4.5 MHz, 5.5 MHz, 6 MHz, 6.5 MHz, 10.5 MHz and 13MHz.

Data transfer rate:

9.6Kbps to 115.2Kbps.

Cable length:

See 3.3.11.

The SIG60 Device

The SIG60 device is responsible for transferring messages to all devices over the line. The device

handles the communication physical layer and Interference detection. The device communicates with its

host via an asynchronous serial port for data transfer and device control. Figure 2.1 outlines the building

blocks of the SIG60 device.
