MoTeC Introduction Introduction Thank you for purchasing a MoTeC SDL Dash / Logger. SDL The MoTeC SDL Dash / Logger is a combined LCD dash unit and high performance data logger.
2 Overview Overview Display The SDL display is a high contrast, high temperature, custom made LCD display. The display contains a Bar Graph, three Numeric Displays, a Centre Numeric Display and a Bottom Alpha / Numeric Display. Bar Graph The 70 segment bar graph has a user definable range and is typically used as a tacho, however it can be used to display any other value. When used as a tacho it may be configured for up to 19,000 RPM. A programmable shift point can be displayed.
MoTeC Overview 3 Numeric Displays The three numeric displays (Left, Right and Top Right) can be programmed to display any value. Note that each of the three numeric displays has a different number of digits and are therefore suited to displaying different values. For example the Top Right display can only show values up to a maximum of 199 and is therefore not suitable for displaying Lap Times, but is suitable for displaying many other values such as Lap Number, Fuel Remaining, Engine Temperature etc.
4 Overview The Centre Numeric display is incorporated to show the current gear but may be used for other purposes. Bottom Display The 13 digit alpha numeric display can display up to 10 lines of information that can be scrolled up or down using the external buttons. Each of the 10 lines can display up to 3 channel values at a time. Additionally the bottom display can show an override value, similar to the numeric displays.
MoTeC Overview 5 Alarms When an alarm is activated a message is shown on the bottom line of the display, a warning light can also be activated which is recommended to draw the drivers attention to the display. The message displayed can be defined and can also include the current sensor reading or the sensor reading when the alarm was triggered. The alarms remain active until they are acknowledged, either by a driver activated switch or automatically after a defined period of time.
6 Overview When the logging memory is full the SDL begins to overwrite the oldest data, which ensures that the most recent data is always available. This is referred to as cyclic logging. Power The SDL power can be turned off at any time without losing the logged data. The SDL uses FLASH memory which does not require an internal battery to keep it alive. Logging Rate The SDL can store any value at up to 200 times per second, which can be individually set for each logged item.
MoTeC Overview 7 km/h, and stop when the engine RPM is below 500 RPM for 10 seconds. Note that the Start Condition must be true and the Stop Condition must be false before logging will start. Retrieving the Logged Data A laptop or desktop PC is used to unload the logged data from the SDL. The logged data is then stored on the computer hard disk. The logged data may be retrieved at very high speed (approximately 2.5 seconds per Mbyte when using USB or 20sec Mbyte when using CAN).
8 Overview Functions: • Shift Lights – Controls up to 3 staged shift lights. • Engine Log – Can be used to record engine running times during the specified condition Calculations: The SDL can calculate and display any of the following: • Lap Time, Running Lap Time, Lap Number. • Ground Speed, Drive Speed, Lap Distance, Trip Distance, Odometer. • Lap Time Gain / Loss continuously displays how far behind or ahead the vehicle is compared to a reference lap. • Current Gear.
MoTeC Overview 9 • 2 Wheel Speed Expander Inputs Additionally one E888 expander may be connected to read from 8 K-type thermocouples. Internal Sensors The SDL also includes internal sensors for G-Force Lateral, G-Force Vertical, Battery Voltage and SDL Internal Temperature. Sensors Different types of sensors are available to suit different types of measurements. Sensors convert a physical measurement (e.g. Pressure) into an electrical signal (e.g. Volts).
10 Overview These inputs can also be used to measure two wire variable resistance sensors if an external pullup resistor is connected from the input to the 5V sensor supply. Additionally, on/off switch signals may be connected, which may also require an external pullup resistor.
MoTeC Overview 11 Input Voltage Range The measurable input voltage range is 0 to 15 Volts. This allows selection from a wide range of sensors. Specifications For full specifications see Appendix D: Input Characteristics. Wide Band Lambda Input The single high accuracy, fully temperature compensated Wide Band Air Fuel Ratio measurement input can be used if the Lambda Option is enabled. This input connects directly to a MoTeC 4 wire Wide Band Lambda Sensor and is accurate to 1.5% up to 1.
12 Overview Specifications For full specifications see Appendix D: Input Characteristics. Speed Inputs The 2 Speed Inputs are identical to the Digital Inputs except that they can also be configured to suit Variable Reluctance (Magnetic) sensors such as some wheel speed sensors. Because the amplitude of the signal from these sensors varies with speed of rotation, variable trigger levels are required, which must vary with the frequency of the input signal.
MoTeC Overview 13 Communications Overview The SDL has various communications ports which are used to communicate with other devices. USB Communications Port The USB communications port is used to communicate with a PC. See Appendix J: USB Wiring for wiring details. RS232 Communications Port The RS232 communications port can be connected to an ECU, GPS or similar device.
14 Overview • Note that if the SDL is connected to a MoTeC M800 ECU the M800 sensors should be calibrated in metric otherwise special scaling will be required. Lap Beacon A Lap Beacon can be connected to the SDL in order to record Lap Times for display and to provide lap reference information for the data logging analysis software. The MoTeC Lap Beacon consists of a Transmitter which is mounted beside the track and a Receiver which is mounted in the vehicle.
MoTeC Overview 15 SDL Sport Dash Manager MoTeC Sport Dash Manager is used for configuration, testing, retrieving the logged data and for general management of the SDL. An overview of Sport Dash Manager is included later in this manual. Sport Dash Manager communicates with the SDL via a USB cable. See Appendix J: USB Wiring for wiring details. Interpreter Interpreter is used to analyse the logged data, this is covered in a separate manual.
MoTeC Installation 17 Installation Mounting Mounting Dimensions Refer to the product dimensions in the Appendices. Attachment Use washers between the unit and the mounting panel to ensure that the unit is mounted only at the mounting points (to avoid twisting the case). The SDL has three threaded mounting posts. Do not over tighten the mounting screws (to avoid twisting the case). Vibration isolation may be desirable if the vehicle vibrates severely.
18 Installation Display Care Take care when cleaning the display, use a soft cloth to avoid scratching the display and avoid aggressive solvents. Wiring Pin Connection Details The SDL pin connection list appears at the back of this manual. Wire Use 22# Tefzel wire (Mil Spec M22759/16-22) (5 amps max at 100 °C) Note that the Tefzel wire is difficult to strip unless the correct stripping tool is used. Be careful not to nick the wires as this may result in wire failure or poor crimping.
MoTeC Installation 19 Power Wiring Power the SDL via a separate switch and a 5 Amp fuse. The separate switch is recommended so that the computer can communicate with the SDL without needing to turn the rest of the vehicle power on. Ground Wiring Ground the SDL to a good ground. The ground should have a direct connection to the vehicle battery. USB Wiring See Appendix J: USB Wiring for USB wiring details. CAN Bus Wiring Refer to Appendix H: CAN Wiring for details.
20 Installation Note that if wired to an Analog Voltage input an external pull-up resistor must be connected between the input pin and the 5V sensor supply. External Lights All lights including the Shift Lights & Warning Lights must be wired externally. This allows a choice of lights and allows the lights to be placed in the optimum position. The MoTeC Shift Light Module (SLM) can be used for this purpose, otherwise LEDs or LED arrays can be used.
MoTeC Installation 21 The MoTeC M4, M48 & M8 ECUs must be connected via RS232. Connection via RS232 The telemetry feature of the MoTeC ECU is used to send data to the SDL via an RS232 connection. See Appendix G: ECU to SDL Wiring (RS232) for wiring details. ECU Setup The ECU ‘Telemetry Set’ and ‘Telemetry Baud Rate’ should be selected to suit an RS232 communications template supported by the SDL. SDL Setup Setup for the SDL is done in the ‘Inputs | Communications’ setup screen.
22 Installation SDL Setup Setup for the SDL is done in the ‘Inputs | Communications’ setup screen. Select a communications template that matches the ECU type and ECU set. In the displayed channel list, check those channels that you wish to receive in the SDL. ECU Sensor Calibrations Metric Calibration of the sensors should be used in the ECU otherwise special scaling is required in the SDL communications setup.
MoTeC Sport Dash Manager Software 23 Sport Dash Manager Software Introduction The following is an overview of the main concepts of the Sport Dash Manager software. More detailed information is available from the online help provided with Sport Dash Manager. Online help is not currently available (Version 1.1.0.49) but will be available at a later stage.
24 Sport Dash Manager Software Installing Sport Dash Manager From a CD-ROM Place the CD-ROM into the CD drive of the pc. A new window will appear. This can be navigated in the same way as a web page. If it does not appear, click on the Windows Start button and select Run. Type ‘D:\index.htm’ Click on the button marked ‘Software Archive’. Select the version of Sport Dash Manager (or other software) that you wish to install and click on the name.
MoTeC Sport Dash Manager Software 25 The main menu is used to access all of the features of the Sport Dash Manager software. Click the mouse on one of the menu items or press the Alt key together with the underlined letter, for example press Alt + F to select the File menu. Unavailable Menu Items When Sport Dash Manager is started the items related to changing the configuration will be unavailable, this is because a configuration file has not been selected. Unavailable items appear grey as shown below.
26 Sport Dash Manager Software To consolidate the Online concept, all on line activities are placed in the ‘Online’ Menu item. All other menu items perform Off Line activities. Configuration The configuration of the SDL determines exactly how it operates. The strength of the SDL lies in its flexibility of configuration.
MoTeC Sport Dash Manager Software 27 Note that the most recently used files appear at the bottom of the File menu, which is often the easiest way to open a recently used file. Sending the Configuration to the SDL The currently open configuration file can be sent to the SDL by selecting Online | Send Configuration from the main menu. When a configuration file is sent to the SDL any changes are automatically saved to the file.
28 Sport Dash Manager Software 2. Calculations (Lap Time, Fuel Prediction etc) 3. Functions (Logging, Display, Alarms, Auxiliary Outputs etc) This simplifies the setup procedure by ensuring that the required channels are available for the functions that use them. • Note that channels cannot be used until they have been generated by an input, calculation or function.
MoTeC Sport Dash Manager Software 29 Channels Channels are used to convey information between the various systems of the SDL. For example an input pin may feed a channel called ‘Engine Temperature’, this channel may then be used by any other system, such as the Display or Data Logging systems.
30 Sport Dash Manager Software Channel List MoTeC has defined an extensive list of channels. All systems within the SDL that generate values must choose to feed into one of these channels. General Purpose Channels Since the use of all channels can not be predetermined, a number of general purpose channels have been included for occasions when a suitable predefined channel is not available.
MoTeC Sport Dash Manager Software 31 • Suitable Display filtering • Minimum and Max Range Predefining these properties makes the channels easy to use throughout the rest of the software, for example knowing the measurement type allows the channels to be displayed in any units suitable for that type, with automatic conversion between the units. For example all temperature channels can be displayed in Celsius, Fahrenheit or Kelvin.
32 Sport Dash Manager Software When selecting a channel from the complete list of channels, it is usually easiest to use the category selection method, for example when assigning a channel to an input pin. To expand a category click on the + sign next to the category name.
MoTeC Sport Dash Manager Software 33 Search Method This method lists all channels in alphabetical order and allows a channel to be found either by typing the first few letters of any word in the channel name, or by scrolling through the list. Note that the words may be typed out of order so that ‘Engine Oil Temperature’ could be found by typing "temp eng oil" or "oil t eng" or "e o t” This method is most useful when selecting a channel from the available channels.
34 Sport Dash Manager Software RPM for 2 seconds. Note that a second alarm could be defined which would cover the range from 500 to 1500 RPM, and which might read as: Engine Oil Pressure < 50 kPa for 1 second AND Engine RPM > 500 RPM for 5 seconds. The following shows an example of an Engine Oil Pressure alarm condition. Checking Operation Monitor Channels The currently active channels can be monitored to allow checking of the operation of all functions and measurements.
MoTeC Sport Dash Manager Software 35 Sensor Zeroing Some sensors require regular zeroing, for example Steering Angle, Suspension Position, Ride Heights, G Force Sensors & Throttle Position. Sport Dash Manager provides a screen to allow easy zeroing of all these sensors. To zero the sensors select Online | Zero Sensors from the main menu. Details Editor The Details Editor allows details about the Event, Venue, & Vehicle to be entered. This data is attached to the logged data file for later reference.

MoTeC Appendices 53 Appendix F: CAN Bus Specification CAN Bus Data Rate: 1Mbit/sec Terminating impedance and data cable impedance: 100 ohms: dictated by the PC communications cable (CAN cable) Maximum length: 16 m (including the CAN Cable if present).
54 Appendices Appendix G: ECU to SDL Wiring (RS232) The following details the methods for connecting the various MoTeC ECUs to the SDL via RS232. In all cases this is done using the serial data stream generated by the Telemetry function of each ECU. In the case of the M800, M880 and M4e the SDL may be directly wired to the ECU because these ECUs use RS232 interface levels. On the M48, M4 (pre M4e) and the M8 a Computer Interface Module (CIM) or a PCI cable is required to convert the signals to RS232.
MoTeC Appendices 55 M48, M4 (pre M4e) and M8 The M48 & M8 and M4 (pre M4e) require the use of a CIM module or a PCI Cable to convert the logic level signals used by these ECU’s into RS232 levels. Using a CIM Module 34 12 SDL M4 / M48 / M8 ECU CIM PC Connector Refer to the CIM module drawing for full wiring details. Note that the data to the SDL will be interrupted while a PC is connected.
56 Appendices Appendix H: CAN Wiring The CAN bus should consist of a twisted pair trunk with 100R (0.25Watt) terminating resistors at each end of the trunk. The preferred cable for the trunk is 100R Data Cable but twisted 22# Tefzel is usually OK. The maximum length of the bus is 16m (50ft) CAN Devices (such as MoTeC SDL, BR2 etc) may be connected to the trunk with up to 500mm (20in) of twisted wire. Note that the “CAN Cable Connector” is not normally used since the SDL uses USB for communications.
MoTeC Appendices 57 Appendix J: USB Wiring The USB connection should be made by wiring a USB cable to the SDL main connector as shown below: The USB cable should have a type B socket so that a standard USB A to B cable can be used to connect between it and the PC. MoTeC can provide a suitable cable (these are not commonly available). Note that the maximum length from ADL to the PC is 5m (16ft) when using a normal USB cable.
58 Appendices Appendix K: Typical Wiring (with BR2) The wiring below shows typical wiring for BR2 on CAN plus USB for PC connection. For more detail on the CAN Bus wiring refer to Appendix H: CAN Wiring. For more details on USB wiring refer to Appendix J: USB Wiring.
