YAMAR Ele c tro ni cs L td Preliminary Data Sheet 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. Host Master 8 8 SIG61 ID 4 8 8 SIG61 ID 4 Battery Power Line Figure 1.1 - SIG61 Application example Applications • • • • • • • • Truck-Trailer sub-bus Door module Climate control network Front and back Lights Sensors Actuators network Entertainment control Green Energy management Security Monitoring © 2010 Yamar Electronics Ltd.

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, Readchange, 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. 2.2 The SIG61 Device Figure 2.1 outlines the building blocks of the SIG61 device.

If, however, switching between two channels is desired, two ceramic filters will be required. The minimum allowable 3dB bandwidth of the ceramic filters is ±70 kHz. Choosing a narrower bandwidth shall limit the maximum achievable bit rate. The SIG61 selectable carrier frequencies are chosen in accordance with ceramic filter values available in the market.

Each of these pins should be connected to the ground via a capacitor. All the corresponding PCB traces should be as short as possible. Recommended crystals are: 1. NDK AT-51 GW. 2. Epson MA-506. The values of C1, and C2 in Figure 3.3, pertaining to the oscillator circuitry, should be determined according to the crystal manufacturer recommendations. Values between 0pF and 4.7pF may serve as good starting point. The overall frequency tolerance should not exceed 200ppm. 3.4 Communication performance The maximum cable length between two devices depends mainly on the AC impedance of loads connected to that line and number of nodes. The DC cable length has less effect on communication. The SIG61 requires a minimum received signal of 20mVpp for proper reception. © 2010 Yamar Electronics Ltd. 7 DS-SIG61 R0.932 Preliminary and proprietary Information of YAMAR Electronics Ltd. Subject to change without notice. 4 DEVICE OPERATION The following paragraph describes the operation of the SIG61 device. 4.1 Protocol The device operation is controlled via 5 types of commands: Write command - Upon receiving a Write command with the SIG61 specific ID, the device shall output the data byte content as indicated by the command to its Output pins. Read command - Upon receiving a Read massage with the SIG61 specific ID, the device shall respond by sending a message containing the status of its Input pins (followed by an appropriate checksum). Read-Change command - When receiving a Read-Change massage with the SIG61 specific ID, the device shall respond to the command by indicating if a pulse upon detecting the first change on its input pins. The response message shall contain the new status of the input pins followed by an appropriate checksum. Sleep command - Upon receiving a Sleep command, the device shall enter a low power-consumption (sleep) mode. A wakeup message generated by the master, or by any of the slaves, wakes up all the devices on the network. This is a global message targeting all the slaves in the network. Change-Frequency command - Upon receiving Change-Frequency command, the device shall switch from its current operational frequency to the other. This command is a global command targeting all the slaves in the network. 4.1.1 Command structure The structure of the five types of commands is detailed below. Command type 1: Write command. The Write command consists of 5 bytes: sync break, sync field, Identifier, data and checksum. The identifier byte begins with the device four ID bits, followed by 00 bits and 2 protection bits. Upon receiving a write command, if checksum and protection bits calculations are successful, the data byte content is transferred to the corresponding output pins. Sync break: Sync break length is at least 13 bit times with compliance to Lin protocol. Protection bits calculation: P0 = (Identifier [0]) XOR (Identifier [1]) XOR (Identifier [2]) XOR (Identifier [4]) P1 = ~ ((Identifier [1]) XOR (Identifier [3]) XOR (Identifier [4]) XOR (Identifier [5])) Checksum calculation: The checksum is an inverted 8 bit sum of the Identifier and Data byte including (own) carry: Checksum = ~ ( Identifier Byte + Data Byte + Carry) © 2010 Yamar Electronics Ltd. 8 DS-SIG61 R0.932 Preliminary and proprietary Information of YAMAR Electronics Ltd. Subject to change without notice. Transmitted command Sync break Sync Field P1, P0, 0, 1, Address Out [7:0] Checksum 3 bit delay SIG61 Outputs at receiving device Figure 4.1 - Write command Command type 2: Read command. The Read command, initiated by the Master, requests the status of the SIG61 input pins. The Read command from the master consists of 3 bytes: sync break, sync field and identifier. The identifier of this command begins with the four-bit ID of the device, followed by “01”, and finally 2 protection bits. The two protection bits are calculated as described above. If header detection is correct (including protection bits), the SIG61 device (whose ID matches the one in the command) shall respond by sending two bytes. A data byte containing the status of its eight input Signal pins followed by a checksum byte. The checksum calculation is carried out as in the description above while part of it, the identifier byte, was transmitted by the Master. Figure 4.2 shows a generic Read command. Sync break Sync Field P1, P0, 0, 0, Address Data (8 input bits) Master Checksum Slave Figure 4.2 - Read command Command type 3: Read-change The Read-change command is similar to the Read command. However, it enables to detect any change in the input pins (pulse-like behavior) that may have occurred between two consecutive Read or Readchange commands. The command from the master instructs the SIG61 to send back information on changes of its input pins since the last Read or Read-change command. The first change on the pin after the Read command sets its bit value. Figure 4.3 shows the process of determining the sent bit value of an input pin. “1” “1” “0” “0” Sent value Change Input pin level Read -change command 1 bit Figure 4.3 - Determining the recent changed value of an input pin The Read-change command from the master has 3 bytes: sync break, sync field and identifier. The identifier begins with the destination device four-bit ID, followed by 10 and terminating with 2 protection bits. The response for this command is a data byte containing the SIG61`s input pins recent changed value, followed by the checksum byte. See checksum and protection bits calculation description above. Figure 4.4 shows a Read-changes command. © 2010 Yamar Electronics Ltd. 9 DS-SIG61 R0.932 Preliminary and proprietary Information of YAMAR Electronics Ltd. Subject to change without notice.

This type of command consist of 5 bytes: sync break, sync field, “3C” Hex, “00” Hex and checksum. The sleep command identifier is “3C”Hex as in LIN2.0 specifications and the following data byte “00”Hex. Upon reception of sync break, sync field, “3C”Hex and “00”Hex bytes, a device enters sleep mode immediately and as a result it’s the following command bytes are ignored. Sync break Sync Field 0x3C Zero byte/bytes Checksum Figure 4.5 - Sleep command Command type 5: Change Frequency command. This type of command consists of 5 bytes - sync break, sync field, “FE” Hex, “00” Hex and checksum. The change frequency command identifier is “FE” Hex and the following data byte is “00”Hex. Upon reception of sync break, sync field, “FE” Hex and “00” Hex bytes the frequency changes from F1 to F0, or vise versa. Checksum calculation follows the description above. Sync break Sync Field 0xFE Checksum Zero byte/bytes Figure 4.6 - Frequency Change command 4.2 Power Management The SIG61 device features Sleep mode for power saving. Entering the Sleep mode, as well as waking up, can be initiated locally, by means of dedicated input pins, or remotely through activity (proper messages) over the bus. 4.2.1 Entering Sleep mode The SIG61 can enter sleep mode by any of the following ways: 1. The device nSleep pin is lowered. 2. Sleep command from a remote master is received. 3. The AutoSleep pin is set HIGH and no reception occurred for about 8 seconds. 4.2.2 Device Outputs during Sleep During Sleep mode, the SIG61 8 output pins remain unchanged if the device has entered this mode due to a Sleep command from the Master or by lowering the Pin nSleep. However if the device entered the Sleep mode due to the AutoSleep function, SIG61 will lower all the outputs to "0". © 2010 Yamar Electronics Ltd. 10 DS-SIG61 R0.932 Preliminary and proprietary Information of YAMAR Electronics Ltd. Subject to change without notice. 4.2.3 Remote wake up process The SIG61 can be awakened by a remote SIG60 master, or SIG61 slave, device transmitting a wakeup message over the bus. During Sleep Mode, the SIG61 wakes up periodically, every 32mSec, to sense for bus activity. If a wakeup message is detected, the SIG61 device raises pin INH and lowers pin HDO. If nSleep pin is low upon remote waking up, the local host (a device controlling the SIG61) which initially pulled nSleep pin down, must raise the nSleep back high. Figure 4.7 provides the signal description. Wakeup Message DC-BUS msg. detected INH HDO Normal mode Standby Figure 4.7 - Wakeup from bus message 4.2.4 Wakeup from Wake pin A transition seen on the Wake pin (caused by an external source) is used to wake up the device. The device then enters Standby mode, it rises pin INH, and transmits a wakeup message to the bus. While transmitting the wakeup message, the device lowers pin HDO. After the transmission is completed the device raises pin HDO. This is depicted in Figure 4.8. After the transmission is completed the device enters Normal mode. If nSleep pin is low upon waking up, the local host which initially pulled nSleep pin down, must raise the nSleep back to high.
