  • Page 3: Introduction

    Introduction Thank you for purchasing a MoTeC SDL Dash / Logger. The MoTeC SDL Dash / Logger is a combined LCD dash unit and high performance data logger. Note that a ‘display only’ version of the SDL is also available This Manual Covers: •...

  • Page 4: Overview

    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.
  • Page 5 MoTeC Overview 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...
  • Page 6 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.

  • Page 7: Alarms

    SDL for later analysis. Logging Memory The SDL comes with an optional 8Mbytes log memory enabled. It is also possible to purchase a ‘display only’ SDL without the memory option enabled. Data is logged continuously logs data to memory whenever the Start...
  • Page 8 Logging Rate The SDL can store any value at up to 200 times per second, which can be individually set for each logged item. The rate at which the values are logged is very important – the value must be logged fast enough to record all variations in the reading.

  • Page 9: Other Functions

    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).

  • Page 10: Measurement Inputs

    This allows the SDL to measure vehicle parameters such as: Suspension Movement, Wheels Speeds, Steering Angle, Engine Temperature etc. Input Types The SDL has a number of different input types which are designed to suit the different types of sensors. The following inputs are available: •...
  • Page 11 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.
  • Page 12 • Two wire variable resistance pressure sensors Some voltage output sensors can also be used if they can drive the 1000 ohm resistor without causing an error in their reading (eg MoTeC Thermocouple Amplifier). Additionally, on/off switch signals may be connected.
  • Page 13 Switch Inputs The 2 switch inputs are generally used for the external switches required to operate the SDL display. They can also be connected to a brake switch or other switch. These inputs have a 4700 ohm resistor connected internally from the input pin to the 5V sensor supply so that a switch can be simply connected between the input pin and 0 volts.

  • Page 14: Auxiliary Outputs

    Expander Thermocouple Inputs An E888 expander may be connected to the SDL to read the 8 thermocouple inputs. These are added and calibrated when the CAN comms template “E8xx Rx EGT” is selected as one of the 6 possible CAN devices.

  • Page 15: Communications Overview

    This avoids duplication of sensors and allows the SDL to display and log many ECU parameters. The ECU may send up to 40 values to the SDL. The update rate of these values depends on how many values are transmitted, the communications baud rate and if sent using CAN or RS232.

  • Page 16: Lap Beacon

    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.

  • Page 17: Updateable Firmware

    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.

  • Page 19: Installation

    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).

  • Page 20: Display Care

    Ensure that the correct crimping tool is used for all contacts to ensure a reliable connection. The correct mil spec crimping tool must be used for the SDL crimp pins. See Appendix N: Connector for details. • Note that the Crimp Contacts are type 22D which is needed to set the...

  • Page 21: External Buttons

    Installation 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.

  • Page 22: External Lights

    The SLM includes 8 LEDs that can be programmed to any colour and can be used for both warning lights and multiple shift lights plus many other functions. The SLM is connected to the SDL via the CAN bus so it does not occupy any of the auxiliary outputs. LEDs LEDs may be wired to any of the four Auxiliary Outputs.
  • Page 23 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.
  • Page 24 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.

  • Page 25: Sport Dash Manager Software

    The PC must have a USB1.0 or compatible USB port or a Printer port. The USB port is the recommended connection method because it is much faster however if necessary a MoTeC CAN Cable may be used instead which should be connected to the printer port.

  • Page 26: Installing Sport Dash Manager

    Software Updates then Current Release Software. Click on one of the SDL Sport Dash Manager link to start the down load and choose to save the file to a location where it can be easily located after downloading (such as the desktop). After downloading double click on the file to start the installation process.

  • Page 27: Toolbar

    All changes to the SDL configuration are performed ‘Off Line’, i.e. without the PC communicating with the SDL. Once the configuration changes have been made and saved to a file, they can be sent to the SDL which is an ‘On line’ process, i.e. the PC is communicating with the SDL.

  • Page 28: Configuration

    Configuration The configuration of the SDL determines exactly how it operates. The strength of the SDL lies in its flexibility of configuration. All aspects of the SDL can be configured including, which sensor is connected to which input, the calibration of each sensor, what to display and where to display it, what to log and how fast to log it, tacho range, warning alarms, multi stage shift lights, etc, etc.

  • Page 29: Changing The Configuration

    ‘Save Backups’ directory. The total number of files is limited to 100. When a file is sent to the SDL the existing SDL data is retrieved and stored in the ‘From Dash Backups’ directory, this is in case the data in the SDL needs to be restored.

  • Page 30: Versions And Updating

    Versions and Updating Updating The software inside the SDL can be updated by the user at any time to take advantage of the latest features offered by MoTeC. To update the SDL software version select Online | Upgrade Dash Version from the Sport Dash Manager main menu.

  • Page 31: Channels

    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.
  • Page 32 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.
  • Page 33 MoTeC Sport Dash Manager Software • 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.
  • Page 34 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.

  • Page 35: Conditions Overview

    MoTeC Sport Dash Manager Software 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.

  • Page 36: Checking Operation

    Utilities | Oscilloscope button on the Monitor Channels screen. Tests A number of tests are provided to check the operation of the SDL, such as the Analogue Input and Auxiliary Output Tests. The Auxiliary Output test is very useful for checking wiring and operation of shift lights for example. The Analogue Input test is very useful when checking sensor wiring.

  • Page 37: Sensor Zeroing

    MoTeC Sport Dash Manager Software 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.

    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.
