SSC Communication Board V4.1
Brief Description
The SSC Modular Evaluation Kit provides hardware
and software for a very simple and intuitive method
of evaluating ZMDI’s sensor signal conditioner
(SSC) ICs. For the evaluation of different SSC ICs,
only the IC-specific SSC Evaluation Board and software are needed; the other parts of the evaluation
hardware (SSC Communication Board and SSC
Sensor Replacement Board) are typically the same.
The SSC Communication Board V4.1* (SSC CB) can
provide the power supply for the evaluation
hardware and handle the communication with a PC
via a USB interface. To prevent malfunctioning or
damage, a galvanic isolation to the PC’s USB port is
established on board via digital isolators for the
information lines and an isolated DC/DC converter
for the power line. It is also possible to supply the
Communication Board and connected kit boards or
user modules by an external power line (12V typical)
via the KL1 screw terminal on the SSC CB. It is also
possible to supply low voltage devices with a fixed
1.8 or 3.3 VDC internal voltage. Alternatively the
connected application could be supplied via the KL2
screw terminal with a voltage of 1.0 to 3.6 VDC.
Features
 Interface fully compatible with USB 2.0
 “Plug & play” capability
 Power for the Evaluation Kit provided by the USB
port or an external power supply as selected with
a jumper setting
 Internal generation of all required voltage levels:
5 VDC and 12 VDC
 On-board galvanic isolation between PC and
evaluation hardware
 Access to all digital communication lines of the
ZMDI SSC IC being evaluated
Benefits
 PC-controlled configuration and calibration via
USB interface – simple, low cost
 Standard communication board for all IC types in
ZMDI’s SSC product family
 USB port driver included in the Evaluation Kit
setup software – simple installation
A USB-UART device transfers all signals to the standardized USB port of the user’s PC. Its UART
interface is connected via digital isolators with the
UART of an on-board microcontroller that controls all
functions of the Evaluation Kit and of the SSC IC to
be evaluated. Its software allows direct communication with the SSC IC via several interface options
2
†
depending on the IC: I C™ , SPI, ZACwire™ (OneWire Interface (OWI)), LIN via a discrete level shifter,
or SENT. The microcontroller also controls the
power lines (5VDC and two lines for 12VDC) by driving several electronic switches. The microcontroller
displays the status of communication via LEDs.
An on-board dual header strip enables access to all
signal and power lines. This allows a simple signal
check; e.g., by a digital oscilloscope, a multimeter, or
a connection with user-specific hardware.
Important: Always ensure that there is no power
when connecting SSC Evaluation Kit boards.

Circuit Description
4.1.
USB Power and the Communication Interface
SSC Evaluation Kits are interfaced to the user’s PC via a Universal Serial Bus (USB). The USB communication is
handled by an FT232R USB-to-UART IC. The communication to the on-board microcontroller is handled by a
common UART line via digital isolators to provide galvanic isolation.
The USB power line supplies the SSC Communication Board via a galvanic isolated 5-to-12V DC/DC converter
circuit. Therefore no additional power supply is required. To fulfill the USB specification for devices with more than
100mA power consumption, the supply input of the subsequent circuit is switched by a MOS transistor, which is
controlled by the USB-UART-interface IC. As a result, the power supply of the connected microcontroller and SSC
Evaluation Board will be switched on after successful PC USB driver initialization. The maximum load current of
the DC-DC converter’s 12VDC output line is 167mA, which is sufficient for supplying the SSC Evaluation Board
hardware and some additional external electronic devices. Alternately, it is possible to supply the SSC Evaluation
Kit by an external 12VDC power line; e.g., to prevent additional noise caused by the DC-DC converter or to allow
more than a 167mA load current at the 12VDC line.

ZSC31xxx / ZSSC3xxx
SSC Communication Board V4.1
The 5VDC supply line is generated by a common LDO linear regulator supplied by the 12VDC line. The
microcontroller (type ATmega1281) handles the communication with the ZMDI SSC IC by using its specific
Evaluation Software running on the user’s PC. All serial protocols are implemented in the microcontroller’s
2
TM
software (I C™ / SPI / LIN / ZACwire (OWI One-Wire Interface)/ SENT), except that for LIN, a discrete LIN level
shifter is used. The communication status of the microcontroller is displayed by five LEDs. The microcontroller
controls both power lines by electronic switches, so a defined power ON/OFF procedure is practicable. A second
switchable 12V power supply labeled as VPP is available because it should be used for generation of the required
memory programming voltage.
The ZMDI SSC Evaluation Board can be connected to the SSC Communication Board via the 50-pin connector.
Additionally, all system signals can be checked via the 50-pin header on board. This can also be used for
connecting external electronics or the user’s own hardware.

5.1.
Special Functions of the SSC Communication Board
Trigger
Most ZMDI SSC ICs need a special start procedure to switch into the Command Mode. Therefore a special timing
and communication procedure after power-on is required. On the SSC Communication Board, this function is
provided by the corresponding supply channels (KS5V, KS12V, VPP(12V), and KSLS). All channels are
controlled via electronic switches.
To connect user-specified hardware, a separate trigger signal can be provided at the TRIG pin. This trigger signal
will be activated by the trigger command (For details, refer to section 6 and the SSC Communication Board
Command Syntax Spreadsheet).
5.2.
Pull-up Resistor for Support of Data Communication
To support reliable data communication, some interfaces (ZACwire™ (OWI One-Wire Interface) and LIN) need an
additional pull-up resistor, which is included on the SSC Evaluation Board. To eliminate any parasitics caused by
this pull-up resistor on the power supply of the SSC IC and data output pin for the selected SSC IC interface, the
pull up resistor must be disconnected from the circuit during the start-up phase. This function is supported by the
TM
switchable pin Tr_D2. The ZACwire , OneWire™, and LIN protocol manipulate the signal on Tr_D2
automatically. For user evaluation boards, connect the pull-up resistor or an external pull-up source to Tr_D2.
As an alternative, the SSC Communication Board V4.1 provides an internal 4.7k pull-up for ZACwire™ and
OneWire™ interface. By default this pull-up will not be used for communication. The pull-up can be enabled by a
special command. Refer to section 6 for general information on commands and the SSC Communication Board
Command Syntax Spreadsheet for a detailed command description.
5.3.
ADC Channel ADC0 to ADC4
The SSC Communication Board provides five ADC channels: ADC0 to ADC4. The ADC0 channel is labeled
TM
“OWI” (ZACwire ); in OWI mode, the ADC0 channel is not available. The ADC channels have a resolution of 10bits. To use these channels, refer to the SSC Communication Board command descriptions that are given in the
SSC Communication Board Command Syntax Spreadsheet.

Digital Channels B4 to B7, D2 to D7, and E2 to E7
The SSC Communication Board provides several bidirectional digital channels B4 to B7, D2 to D7, and E2 to E7.
The D2 channel is not available during ZACwire™ (i.e., OWI, digital One-Wire Interface) and LIN communication
(reserved for pull-up switching as described in section 5.2). The output channels have tri-state functionality. To
use these channels, refer to the SSC Communication Board command descriptions in the SSC Communication
Board Command Syntax Spreadsheet.
5.5.
RXD/TXD Interface
The RXD and TXD pins available on the SSC Communication Board’s 50-pin connector (K5/K6) provide the serial
protocol that is used for communication between the USB serial connector and the microcontroller.
5.6.
LIN Channel
The LIN channel provides a 12V LIN-complaint signal to connect to LIN-compliant devices (LIN specifications 1.3,
2.0, and 2.1). Discrete circuitry converts the 5V microcontroller signal to the 12V LIN level and vice versa. To use
this channel, refer to the SSC Communication Board command descriptions in the SSC Communication Board
Command Syntax Spreadsheet.
5.7.
I²C™ Channel
The I²C™ communication protocol is provided at the SCL (clock) and SDA (serial data) pins. To use this channel,
refer to the SSC Communication Board command descriptions in the SSC Communication Board Command
Syntax Spreadsheet. On the board, there are pull-up resistors of 4.7kΩ each, which are connected to the
switched KS5V power line.
5.8.
SPI Channel
The SPI communication protocol is provided at the MOSI (Master Out Slave In), MISO (Master In Slave Out), and
SCK (Clock) pins. To use this channel, refer to the SSC Communication Board command descriptions in the SSC
Communication Board Command Syntax Spreadsheet.
5.9.
OWI Channel (ZACwireTM)
The ZACwire™ (i.e., OWI, digital One-Wire Interface) communication protocol is provided at the OWI pin. To use
this channel, refer to the SSC Communication Board command descriptions that are given in the SSC Communication Board Command Syntax Spreadsheet.
5.10. VPP Pulse Generation
At the VPP pin, a second 12V power supply can be provided that is intended to be used for a special EEPROM
programming pulse generation. However, this VPP pin can also be used for any other 12V purpose. To use this
pin, refer to the SSC Communication Board command descriptions in the SSC Communication Board Command
Syntax Spreadsheet.

5.11. 5V Channel
At the 5P pin, a stabilized voltage of 5VDC is available to supply external circuits. The KS5V channel provides the
same voltage, controlled by the microcontroller via an electronic switch to provide special IC start-up scenarios.
To use this channel, refer to SSC Communication Board command descriptions in the SSC Communication
Board Command Syntax Spreadsheet regarding trigger pulse generation.
5.12. 12V Channel
At the 12P pin, a stabilized voltage of 12VDC is available to supply external circuits if the kit is supplied via USB.
When supplying the kit with an 8 to 16 VDC by an external power supply via screw terminal KL1, this voltage is
available at the 12P pin. The KS12V channel provides the same voltage, as controlled by the microcontroller via
an electronic switch to provide special IC start-up scenarios. To use this channel, refer to the SSC Communication Board command descriptions in the SSC Communication Board Command Syntax Spreadsheet.
5.13. Level Shifter Channel
The Communication Board provides also the option to communicate with low voltage devices using a level shifter.
The voltage operation range can be set to fixed internal 1.8V or 3.3V or via KL2 to a freely selectable range of
1.0 to 3.6 VDC.
The control signals for the level shifter and the power supply line are given in the SSC Communication Board
Command Syntax Spreadsheet.
The level shifted signals are labeled with “LS” on the K5 and K6 connectors. At the VDD-LS pin, a stabilized low
voltage is available to supply external circuits. The KSLS channel provides the same voltage, controlled by the
microcontroller via an electronic switch to provide special IC start-up scenarios.
The I²C™, SPI, ZACwire™ (OWI), and one digital channel (D3) are transferred via level shifter to the low voltage
domain. If more than one digital channel will be required by the application the remaining pins of I²C ™, SPI, or
ZACwire™ (OWI) can also be used.

SSC Evaluation Kit Controller Language
The SSC Communication Board contains a microcontroller with an 8-bit wide internal RISC processor. The
communication between this microcontroller and the user’s PC is addressed by a serial protocol. The USB-toserial converter transforms this signal into a USB-complaint data stream. To allow control of the SSC
Communication Board with a PC, the USB data is forwarded to a virtual serial interface (virtual COM port) or FTDI
D2XX.DLL. This communication is implemented by the USB driver (see section 3.2).
To control the SSC Communication Board, a software interface is necessary. ZMDI’s Evaluation Kits include
software that provides this interface.
Alternately, the user’s software can be used, or for the simplest cases, a terminal program (e.g., HyperTerminal)
can communicate using the corresponding virtual COM port via defined commands with the SSC Communication
Board hardware. The configuration for this method and for all user software is as follows:

SSC Terminal Program
ZMDI’s SSC Terminal Program is a basic terminal program adapted to the communication parameters of the SSC
Communication Board. The communication procedure for the different software modules is based on this model.
This program is available in a zip file on the “Evaluation Tools” page (www.zmdi.com/ssc-tools). First download
the zip file and then extract the software. Click on the extracted file to activate the terminal program.
Recommendation: To receive notices of updates for software and documents on ZMDI’s web pages, set up a free
customer login account for the ZMDI website. To set up a login account, go to www.zmdi.com and click on Login
in the upper right corner. Then follow the dialog instructions to set up a user name and password, and then login.
Below the heading for each product page, there will now be a link to the account profile, which has a tab for
selecting user notifications for various product types.
6.2.
SSC Evaluation Kit Controller Language Commands
The commands can be classified as READ, WRITE and SPECIAL commands. Every command that is sent to the
hardware is answered by an acknowledge plus a “value” or a not-acknowledge plus a corresponding error code.
For the typical ZMDI SSC IC data structure, refer to the corresponding data sheet and/or functional description.
Depending on the type of SSC IC, a special start-up sequence is necessary to switch the IC to the digital
communication mode. To handle this sequence, a special trigger command is provided. The trigger values can be
selected with a special preparation call. This call configures the channel, which must switch off and on before the
first data packet can be sent. The execution of this trigger command can be selected within a subsequent
read/write procedure. The switch-off time before a trigger event is executed can also be programmed. The default
value is 300ms. The trigger time is related to the command window parameters of each product. Refer to the SSC
IC product datasheet for further information.
*
SSC CB will interpret CR as the command terminator and will start execution of the command. The string from SSC CB to PC will always
be terminated with <CR><LF>.
