SIG61 - Smart Slave for

DC-BUS Powerline Network

This information is preliminary and may be changed without notice

1 GENERAL

The SIG61 is an independent slave in a DC-BUS Powerline communication network controlled by a

SIG60 master device. The SIG61 has 4 identification (ID) pins, used to set the device address, 8 input

pins and 8 output pins. The master can access any SIG61 device independently by using the proper

device address. Data received from a remote SIG60 Master device is reflected to its output pins. The

Master device can read the SIG61 input pins remotely. Its small footprint integrates most of the

components needed for proper operation allowing small-size control solutions.

The SIG61 is an economical slave device for applications such as controlling motors, reading sensors

etc., eliminating the need for dedicated control wires and a host controller for its operation. It helps

reducing the harness size and increase reliability. The SIG61 has a sleep mode that enables power

saving; special Wakeup messages on the DC line are used to signal the sleeping devices to return to

normal operation mode.

The SIG61 is useful for a wide range of Automotive, Avionics and Industrial applications such as sensor

reading, actuator activation, doors, seats, mirrors, climate control, lights, Truck-Trailer, etc.

2 OVERVIEW

The SIG61 is an independent slave in a Master-Slaves network operating on a selected narrow band

channel. A single SIG60 master controls all the slaves in a network; the slaves may be SIG61 devices

as well as SIG60 devices operating as slaves.

Proper Network operation is maintained by employing 5 types of command messages:

Read, Read-

change, Write, Sleep

and

Change-Frequency.

The command format is similar to the standard Universal

Asynchronous Receiver Transmitter (UART).

The SIG61 has internal narrow band modem, capable of operating in noisy environments. The receiver

listens to the DC-BUS on its preset frequency. It filters out the signal from noise and interference and

tries to recover the original command. If the checksum is correct, the SIG61 extracts the ID, Command

and the Data.

If the received ID matches its own ID, the SIG61 proceeds to detect the received command. When a

Write command is received, the data part of the command is directed to the corresponding 8 output

pins. When a Read command is detected, the SIG61 responds by transmitting a dedicated message

towards the master containing an image of its 8 input pins.

Multiple networks can operate concurrently on the same wire using different carrier frequencies.

2.1

Channels and Network

The SIG60-SIG61 network supports 16 combinations of frequency pairs. When set to such a pair, it is

easy to switch from one frequency to the other when such need arises. Each channel accommodates a

single SIG60 master and up to 15 SIG61/SIG60 slave devices. Additional SIG60-SIG61 networks can

coexist on the same power line by employing different frequencies for each network, thus allowing

different applications.

Channel frequencies: 1.75MHz, 4.5MHz, 5.5MHz, 6.0MHz, 6.5MHz, 10.5MHz and 13.0MHz.

Data transfer rate:

9.6Kbps up to 115.2Kbps.

Cable length: Dependant on external AC loads connected to the DC line.
