MoTeC Introduction 1
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. Note that a ‘display only’ version of the SDL is also
available
This Manual Covers:
• Overview of the SDL capabilities
• Installation
• Overview of the MoTeC SDL and Sport Dash Manager software
Software Information
For detailed information on using the various software programs refer to the
online help supplied with the program.
Other Manuals
Separate Manuals are available for:
• MoTeC Lap Beacon / BR2
• Interpreter Data Analysis Software
Sensor Details
Drawings are available for all MoTeC sensors and can be found on the
MoTeC Resource CD (included with the SDL) or on the MoTeC website at
www.motec.com.au
requirements for each sensor.
. The drawings detail the mounting and wiring
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.
The numeric displays can show any channel value plus an override value,
shown each time the value is updated. This is useful for values that are
updated periodically, for example Lap Time. The override values are shown
for a programmable period of time, for example a numeric display could
normally show the Running Lap Time (which is continuously updating) then
be overwritten by the Lap Time for 10 seconds each time the Lap Time is
updated.
Enunciators for some of t he common display values are provided above the
numeric displays, eg. ET (Engine Temperature), OP (Oil Pressure).
Centre Numeric Display
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.
The bottom display will also show any active alarm messages, which will
override all other values until the alarm is cleared.
Display Formatting
Units
The display units can be changed to suit the driver, for example the driver
may prefer to see the engine temperature in Fahrenheit rather Celsius. This is
independent of the units used for other purposes.
Decimal Places
The number of decimal places can be reduced for display purposes, for
example the engine temperature is measured to 0.1 °C but is better displayed
with no decimal places. This is normally done automatically.
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.
The warning alarm limits are fully programmable and may include up to 2
comparisons to ensure that the alarms are only activated at the correct time.
For example, an engine temperature alarm may activate at 95 °C if the
ground speed has been above 50 km/h for 30 seconds. The speed
comparison avoids the alarm showing during a pit stop due to heat soak.
Additionally another comparison could be set at a higher temperature to cover
all other situations.
Data Logging
Data logging allows the sensor readings (or any calculated value) to be stored
in the 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
Condition is true (and the Stop Condition is false).
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.
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. If the value is
logged too slowly then the readings can be totally meaningless. For example
suspension position normally needs to be logged at 100 times per second or
more.
Note, however, that if a value is logged faster than necessary it will not
improve the accuracy of the logged data, it will just reduce the total logging
time available. For example, the engine temperature only needs to be logged
at once per second.
Logging Time
The maximum logging time is dependent the number of items logged and the
rate at which they are logged. The configuration software will report the
logging time, taking these factors into account.
Logging Rates
The logging Rate may be individually set for each value between 1 to 200
times per second.
Start and Stop Logging Conditions
Two options are provided; the default is to log data while the engine is
running. The condition is to start when Engine RPM >= 200 rpm for 2
seconds. Logging will stop when Engine RPM < 200 rpm for 20 seconds. This
requires that the Engine RPM channel is present in the configuration.
The alternative is to specify start and stop logging conditions to suit the
application. For example logging might start when the vehicle exceeds 50
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).
After each unload the user has the option to clear the logging memory.
The unload may be interrupted part way through if necessary by
disconnecting the computer. The partial unload will contain the most recently
logged data and will be stored on the computer hard disk. In this case the
SDL logging memory is not cleared and logging will continue as normal at the
end of the existing data. Next time the logged data is unloaded both the new
data and the previously partly unloaded data will be retrieved.
Track Map Sensor Requirements
In order for the logging analysis software to plot a track map the following
sensors are required and must be logged.
• Lateral G force (inbuilt in the SDL)
• Wheel Speed
• Lap Beacon (from either MoTeC Beacon kit or a switch. Note that the
‘Beacon’ Channel must be logged)
• Longitudinal G force (Optional: See Below)
A Longitudinal G force sensor should be used if the vehicle has only one
wheel speed sensor. This allows the analysis software to eliminate wheel
lockups which is essential when creating or using a track map.
Other Functions
The SDL can perform many other functions and calculations including the
following:
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.
• Minimum Corner Speed, Maximum Straight Speed.
• Fuel Used, Fuel Remaining.
• Two 2D and two 3D Lookup Tables
Measurement Inputs
The SDL measurement inputs can be connected to a wide variety of sensors.
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:
• 8 Voltage Inputs
• 4 Temperature Inputs
• 1 Optional Wide Band Air Fuel Ratio Input (Lambda Input)
• 2 Switch Inputs
• 2 Digital Inputs
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). Different types of sensors generate different types of
electrical signals. For example most temperature sensors convert the
temperature into a variable resistance signal which may be measured by the
SDL Temperature inputs, however most wheel speed sensors generate a
variable frequency signal which must be connected to either a Digital input or
a Speed input.
Calibration
Calibration is the process of converting the electrical value, e.g. Volts into a
number that represents the physical value, e.g. Temperature.
All inputs can be calibrated to suit the connected sensor.
The calibrations can be selected from a number of predefined calibrations
provided by MoTeC, or they can be entered by the user.
Analog Voltage Inputs
The 8 Analog Voltage inputs are normally used to measure the signals from
analog voltage type sensors, i.e. sensors with variable voltage outputs, such
as:
• Rotary or linear potentiometers
• Signal conditioned 3 wire pressure sensors
• Thermocouple amplifiers
• Accelerometers
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.
Measurement Methods
These inputs can be configured to use several measurement methods to suit
the various types of sensors:
• Absolute Voltage: The sensor voltage is independent of the sensor supply
voltage
• Ratiometric Voltage: The sensor voltage is proportional to the 5V sensor
supply voltage
• Variable Resistance: The sensor resistance can be entered directly.
• On/Off : The voltage for on and off can be defined
Input Voltage Range
The measurable input voltage range is 0 to 5.5V on inputs AV1 to 4 and is 0
to 15 Volts on all other AV inputs.
Specifications
For full specifications see Appendix D: Input Characteristics.
Analog Temp Inputs
The 4 Analog Temp inputs are identical to the Analog Voltage inputs, except
that they contain a 1000 ohm resistor which is connected internally from the
input pin to the 5V sensor supply. This allows the Analog Temp inputs to be
used with two wire variable resistance sensors such as:
• Two wire thermistor temperature sensors
• 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.
Measurement Methods
These inputs use the same measurement methods as the Analog Voltage
Inputs.
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 1.2 Lambda under all load and temperature
conditions.
Note that this is the Bosch LSM sensor and not the 5 wire Bosch LSU sensor.
Note that NTK Lambda sensors should be connected to an Analog Voltage
input via the appropriate amplifier.
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.
Specifications
For full specifications see Appendix D: Input Characteristics.
Digital Inputs
The 2 digital inputs are identically to the switch inputs except that they include
the following additional measurement methods:
• Frequency: The frequency of the input signal is measured
• Period: The time between successive pulses is m ea sure d
• Pulse width: The low time of the pulse is measured
• Count: Counts the number of pulses
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.
The Speed Inputs can also be used with Hall Effect type wheel speed
sensors.
• Note also that the Pulse Width measurement method measures the high
time of the pulse rather than the low time as measured by the Digital
Inputs.
Specifications
For full specifications see the Appendices.
Internal Sensors
The SDL includes internal sensors for G force lateral, G force Vertical, battery
voltage and internal temperature.
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.
Auxiliary Outputs
The SDL has 4 Auxiliary Outputs which may be used to control various
vehicle functions such as: Gear Change Lights, Warning Lights, Thermatic
Fan, Gear Box Oil Pump, etc. The outputs are On/Off only and do not support
variable frequency or duty cycle control.
The Auxiliary Outputs switch to ground and can drive up to 0.5 Amps. Devices
that consume more than 0.5 Amps such as motors should be driven via a
relay.
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.
CAN Communications Port
The CAN (Control Area Network) communications port can be connected to
other devices with a compatible CAN port. The advantage of CAN is that
many devices can be connected to the CAN bus at once, which allows all
connected devices to communicate with each other, also the CAN port
communicates at very at high speed.
Other MoTeC products that use CAN for intercommunication include the
M800, BR2, PLM and MDD.
Note that these devices communicate at 1Mbit/sec, so any other devices
connected on the CAN bus must also communicate at 1Mbit/sec.
ECU Connection
The SDL can be connected to many Engine Management Systems (ECUs).
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. For RS232 the typical update rate
is about 20 times per second and for CAN it is about 50 times per second.
Note that logging the ECU values faster than these rates is unnecessary and
will reduce the total logging time.
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 Transmit ter which is m ount e d beside
the track and a Receiver which is mounted in the vehicle.
A switch can also be used to generate lap times, although this is significantly
less accurate than a l a p beacon system.
For further details refer to the Lap Beacon manual.
Options
Various options allow the SDL to be upgraded to perform additional functions,
specifically wide band lambda measurement and Pro Analysis.
The options can be enabled at any time by calling your MoTeC dealer,
purchasing the upgrade and then entering the upgrade password.
See Appendix B: Options Summary for details.
Software
The SDL comes with software packages for managing the SDL and analysing
the logged data. All software required is available on the CD provided, or can
be downloaded from the internet. Go to www.motec.com.au
links to “Software”.
and follow the
The software must be run on a laptop or desktop computer running Windows
98/2000/XP.
The following software programs are provided:
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 communica tes 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.
BR2Config
This program is used to configure the BR2 beacon receiver via a CAN
connection. BR2 configuration is covered in the BR2 Manual.
Updateable Firmware
The SDL control software (firmware) is field updatable so that new software
features can be used as they become available.
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.
Orientation
For best contrast, the display should be viewed at approx imately 20 degrees
above normal, however the SDL will give good contrast between 0 and 40
degrees. Display reflections should also be considered when determining the
mounting angle.
Note that for accurate readings from the inbuilt vertical G sensor the SDL
should be mounted as close to vertical as possible.
20°
Connector Access
Mount so that the connector may be easily accessed.
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.
Some sensor connectors may not be available with 22# terminals, in which
case doubling the wire over gives the equivalent of an 18# wire, which is
suitable for many of the common sensor terminals.
For full wire specifications see Appendix P: Wire Specifications.
Connector
The SDL uses a 37 pin Auto Sport connector, see Appendix N: Connector for
full details.
To ensure that the connector is sealed plug unused holes with filler plugs. A
heat shrink boot may also be used if desired.
Crimping
Ensure that the correct crimping tool is used for all contacts to ensure a
reliable connection.
The correct mil spec crimping to ol 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
crimp tool correctly.
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.
Sensor Wiring
MoTeC can supply wiring details for all sensors.
External Buttons
A number of external buttons are required for various functions of the SDL.
Typically these buttons are used for:
• Display Next Line
• Alarm Acknowledge
• Lap Number Reset
• Fuel Used Reset (can also be done by holding the alarm acknowledge
button for 2 seconds)
These buttons are normally wired to the SDL Switch Input pins, but may also
be wired to the Digital or Analog Inputs, if the Switch Inputs are occupied.
Note that it is possible to configure the ADL to use the Alarm Acknowledge
button to reset the Lap Number and Fuel Remaining by holding it for a period
of time. This reduces the number of buttons required.
The buttons should be wired between an SDL input and SDL 0V pins.
