MoTeC Introduction 1
Introduction
Thank you for purchasing a MoTeC ADL Dash / Logger and/or EDL Enclosed
Data Logger
ADL
The MoTeC ADL Dash / Logger is a combined LCD dash unit and high
performance data logger.
EDL
The EDL is a model of the ADL that is manufactured without a display screen.
Aside from this, it functions in the same way, using the same software as the
ADL. In the remainder of this manual when reference is made to the ADL, it
also refers to the EDL – except when referring to the display.
This Manual Covers:
• Overview of the ADL/EDLs capabilities
• Installation
• Overview of the MoTeC 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. The drawings detail all
mounting and wiring requirements for each sensor.
2 Overview
Overview
Display
The ADL 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 fully programmable shift point can be displayed, which can also be gear
dependent.
MoTeC Overview 3
The operation of the bar graph can be different for each of the display modes
(Race Practice and Warmup), this allows a lower range to be used in Warmup
mode.
Numeric Displays
The three numeric displays (Left, Right and Top Right) can be programmed to
display any value, which may be different for each of the display modes
(Race Practice and Warmup).
Note that each of the three numeric displays has a different number of digits
and are therefore suited to displaying different values. Fox 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 of Fuel Remaining, Engine Temperature etc.
The numeric displays can show any channel value plus up to two override
values, which are shown each time their 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 the common display values are provided above the
numeric displays, eg. ET (Engine Temperature), OP (Oil Pressure).
4 Overview
Centre Numeric Display
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 20 lines of information
that can be scrolled up or down using the external buttons. Each of the 20
lines can display up to 3 channel values at a time.
The values shown may be different for each of the three display modes.
Additionally the bottom display can show up to four override values, 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 Modes
The display has three main modes of operation, Race, Practice and Warm
Up.
MoTeC Overview 5
Warm Up
The warm up display is used to display important engine sensor readings
during engine warm up, eg, RPM, Battery Voltage, Engine Temperature, Oil
Pressure, Oil Temperature & Fuel Pressure.
The bottom display may be used display many other values that may need
checking during warm up.
Practice
The practice display is used to display basic information, plus information to
help the driver improve lap times, eg. Lap Time, Lap / Gain Loss, Maximum
Straight Speed, Minimum Corner Speed or Corner Exit Speed.
The bottom display may be used to display additional information as needed.
6 Overview
Race
The race display is normally used to display minimal information, eg RPM,
Lap Time, Fuel Remaining or Laps Remaining.
The bottom display may be used to display additional information as needed.
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.
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.
MoTeC Overview 7
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 6
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.
The comparison values can be automatically incremented or (decremented)
when an alarm occurs. For example the engine temperature alarm may be set
at 95°C with and increment of 5°C, so that the second time the alarm
activates it activates at 100°C. A limit may be set on the number of times the
comparison value is allowed to increment, also it may return to its original
value after a period of time, in case the alarm condition was temporary.
The alarms can also be dependent on the current display mode (Race,
Practice or Warmup)
Data Logging
Data logging allows the sensor readings (or any calculated value) to be stored
in the ADL for later analysis on a Personal Computer.
Logging Memory
The ADL comes with 8 Mbytes of logging memory. Various options determine
how much of the memory can be used and whether Fastest Lap Logging and
Burst Logging are enabled.
See the Options Summary in the Appendices for details.
8 Overview
Power
The ADL power can be turned off at any time without losing the logged data.
The ADL uses FLASH memory which does not require an internal battery to
keep it alive.
Logging Rate
The ADL can store any value at up to 1000 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.
Update Rate
Not all values are updated 1000 times per second, and logging them faster
than their update rate will simply waste memory.
The update rates for all input types are listed below:
Input Type Update Rate
(times per second)
Analog Voltage Inputs 1 to 4 & 11 to 14 1000
Other Analog Voltage Inputs 500
Analog Temp Inputs 500
Lambda Inputs 100
Digital Inputs & Speed Inputs 100
RS232 & CAN Communications 50 max *
* Note that the RS232 & CAN Communications update depends on how
frequently the data is sent from the device. Typically the update rate from an
M4, M48, M8 or M800 ECU is about 20 times per second using RS232, and
about 50 times per second for the M800 using CAN.
MoTeC Overview 9
Logging Time
The maximum logging time is dependent on the logging memory size, the
number of items logged and the rate at which they are logged. The
configuration software will report the logging time, taking all these factors into
account.
Logging Types
The ADL provides three ways of logging the data: Normal Logging, Fastest
Lap Logging and Burst Logging.
Normal Logging
Normal Logging continuously logs data to memory whenever the Start
Condition is true (and the Stop Condition is false).
Logging Rates
The logging Rate may be individually set for each value between 1 to 1000
times per second.
Start and Stop Logging Conditions
To avoid logging unnecessary data, logging can be started and stopped by
user definable conditions. For example logging might start when the vehicle
exceeds 50 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.
Memory Filling Options
When the logging memory is full the ADL may be configured to either stop
logging, or to overwrite the oldest data, which ensures that the most recent
data is always available. This is referred to as cyclic logging.
For most applications it is recommended that cyclic logging is used.
Logging Setup Files
The logging list can be saved and loaded from a file. This allows multiple
logging setups to be used.
10 Overview
Fastest Lap Logging
Fastest Lap logging records data for the Fastest Lap since the data was last
retrieved. Normally this is used for items that require fast logging rates, such
as suspension position. This allows the available memory is used more
efficiently.
Note that Fastest Lap Logging requires that a Lap Beacon is connected.
Fastest Lap Logging is in addition to and works concurrently with Normal
Logging.
Up to 50 values may be logged.
Logging Rates
The logging Rate may be individually set for each value between 1 to 1000
times per second.
Maximum Lap Time
Note that a maximum Lap Time must be entered which indicates to the ADL
how much memory to reserve for fastest lap logging. If there are no Lap
Times less than this value then Fastest Lap data will not be available.
Memory Occupied
The amount of memory occupied by Fastest Lap logging depends on how
many items are logged, how fast they are logged and the specified maximum
Lap Time. The effect on normal logging time is shown in the configuration
software.
Logging Setup Files
The logging list can be saved and loaded from a file. This allows multiple
logging setups to be used.
Burst Logging
Burst logging allows data to be captured at high speed without wasting large
amounts of memory.
Two independent burst logging systems are available.
Up to 20 values may be logged for each.
MoTeC Overview 11
Logging Rates
The logging rate may be set between 100 and 1000 times per second and is
the same for all logged items.
Trigger Conditions
Burst logging is triggered when a defined condition becomes true.
Note that the normal Start and Stop Logging conditions do not affect burst
logging.
Trigger Position
Burst logging can capture data before and/or after the burst start condition
becomes true (trigger event). This is because the burst logging data is stored
continuously, overwriting the oldest data as necessary. When the trigger
event occurs, a proportion of the old data (before the trigger event) is kept
and the rest of the memory is filled with new data (after the trigger event).
Events and Memory
Up to 8 events can be captured for each of the two burst systems. Each burst
event occupies 64 kbytes of memory (1/16
The number of events may be set by the user. Note that this will affect the
amount of memory available for normal logging.
th
of a Mbyte).
Logging Time
Since each burst event is fixed at 64 kbytes of memory, the burst logging time
is dependent on how many items are logged and how fast they are logged.
The burst logging time is reported by the configuration software.
For example 8 items logged at 500 times per second will last 8.2 seconds.
Retrieving the Logged Data
A personal computer is used to unload the logged data from the ADL. The
logged data is then stored on the computer hard disk.
The logged data may be retrieved at very high speed (approximately 20
seconds per Mbyte).
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
12 Overview
logged data and will be stored on the computer hard disk. In this case the
ADL 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
• Wheel Speed
• Lap Beacon (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 ADL can perform many other functions and calculations including the
following:
Functions:
• Shift Lights
• Engine Log
Calculations:
The ADL can calculate and display any of the following:
• Lap Time, Lap Speed, Running Lap Time, Split Lap Times, Lap Number,
Laps Remaining.
• Lap Time Gain / Loss continuously displays how far behind or ahead the
vehicle is compared to a reference lap.
• Current Gear.
MoTeC Overview 13
• Minimum Corner Speed, Maximum Straight Speed and other Min/Max
values.
• Fuel Used, Fuel Usage, Fuel Remaining, Laps Remaining, Fuel Used per
Lap.
General Purpose Calculations:
The ADL also provides a number of general purpose calculations including:
• 2D and 3D Lookup Tables
• User Defined Conditions
• General Purpose Timers
• Mathematics
The user defined conditions or tables can be used to activate items such as a
Thermatic Fan or Gearbox Oil Pump.
Measurement Inputs
The ADL measurement inputs can be connected to a wide variety of sensors.
This allows the ADL to measure vehicle parameters such as: Suspension
Movement, Wheels Speeds, Steering Angle, Engine Temperature etc.
Input Types
The ADL has a number of different input types which are designed to suit the
different types of sensors.
The following inputs are available:
• 20 Voltage Inputs
• 8 Temperature Inputs
• 2 Wide Band Air Fuel Ratio Inputs (Lambda Inputs)
• 4 Switch Inputs
• 4 Digital Inputs
• 4 Wheel Speed
14 Overview
Options
The number of inputs that can be used depends on which options are
enabled. See the Options Summary in the Appendices for details.
Internal Sensors
The ADL also includes internal sensors for Battery Voltage and ADL 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
ADL 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 M oTe C , or they can be entered by the user.
Analog Voltage Inputs
The 20 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
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
MoTeC Overview 15
sensor supply. Additionally, on/off switch signals may be connected, which
may also require an external pullup resistor.
Options
Note that the number of inputs that are available depends on which options
are enabled. See Appendix B: Options Summary for details.
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 15 Volts. This allows selection
from a wide range of sensors.
Specifications
For full specifications see Appendix D: Input Characteristics.
Analog Temp Inputs
The 8 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 M oTe C Thermocouple
Amplifier). Additionally, on/off switch signals may be connected.
16 Overview
Options
Note that the number of inputs that are available depends on which options
are enabled. See Appendix B: Options Summary for details.
Measurement Methods
These inputs use the same measurement methods as the Analog Voltage
Inputs.
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 Inputs
The two high accuracy, fully temperature compensated Wide Band Air Fuel
Ratio measurement inputs can be used if the Lambda Option is enabled.
These inputs connect directly to a M oTe C 4 wire Wide Band Lambda Sensor
and are 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.
Note that NTK Lambda sensors should be connected to an Analog Voltage
input via the appropriate amplifier.
Switch Inputs
The 4 switch inputs are generally used for the external switches required to
operate the ADL 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.
Options
All four inputs are available irrespective of which options are enabled.
MoTeC Overview 17
Specifications
For full specifications see Appendix D: Input Characteristics.
Digital Inputs
The 4 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 measured
• Pulse width: The low time of the pulse is measured
• Count: Counts the number of pulses
• Beacon: For connection of a lap beacon
Options
Note that the number of inputs that are available depends on which options
are enabled. See Appendix B: Options Summary for details.
Specifications
For full specifications see Appendix D: Input Characteristics.
Speed Inputs
The 4 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 that Inputs 1 & 2 use common trigger thresholds and a common
pullup resistor switch, as do Inputs 3 & 4, therefore the same type of
sensors need to be used on each pair of inputs.
• 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.
18 Overview
Options
Note that the number of inputs that are available depends on which options
are enabled. See the Options Summary in the Appendices for details.
Specifications
For full specifications see the Appendices.
Internal Sensors
The ADL includes internal sensors for battery voltage and internal
temperature.
Electrical Specifications
See the Appendices for more detail on each type of input.
Auxiliary Outputs
The ADL has 8 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.
Items such as Thermatic Fans or Pump Control should be setup using the
User Conditions or the general purpose Tables, there is no specific setup item
for these types of devices.
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.
They Auxiliary Outputs can be configured for switched or pulsed control.
Options
Note that the number of outputs that are available depends on which options
are enabled. See Appendix B: Options Summary for details.
Specifications
For full specifications see Appendix E: Auxiliary Output Characteristics.
MoTeC Overview 19
Communications Overview
The ADL has two communications ports which are used to communicate with
other devices.
RS232 Communications Port
The RS232 communications port can be connected to an ECU or similar
device and to a Radio Telemetry device. A M oTe C telemetry kit is available
which provides high quality data transmission and flexible data display.
• Note that when connected to both an ECU via RS232 and to a Telemetry
device, the baud rates of the two devices must be the same (usually 9600
or 19200 baud).
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 M oTe C products that use CAN for intercommunication include the
M800, BR2, PLM and MDD.
Note that these communicate at 1Mbit/sec, so any other devices connected
on the CAN bus must also communicate at 1Mbit/sec.
The CAN communications port is also used for all PC communications,
including configuration of the ADL and unloading the logged data.
ECU Connection
The ADL can be connected to most Engine Management Systems (ECUs).
This avoids duplication of sensors and allows the ADL to display and log
many ECU parameters.
The ECU may send up to 40 values to the ADL. 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.
20 Overview
• Note that if the ADL is connected to a M oTe C M800 ECU the M800
sensors should be calibrated in metric otherwise special scaling will be
required.
Telemetry
The ADL can transmit real time and/or end of lap telemetry data. This allows
monitoring of the current vehicle condition, position on the track, lap times,
fuel remaining, laps remaining etc.
The real time telemetry data is transmitted continuously.
The end of lap telemetry data is transmitted at a specified time after the lap
beacon is detected
• Note that if RS232 ECU communications is used then the telemetry baud
rate must be the same as the ECU communications baud rate (normally
9600 or 19200 baud)
• Note that the Telemetry option is required.
Lap Beacon
A Lap Beacon can be connected to the ADL in order to record Lap Times for
display and to provide lap reference information for the data logging analysis
software.
The M oTe C Lap Beacon consists of a Transmitter which is mounted beside
the track and a Receiver which is mounted in the vehicle.
Multiple beacon transmitters may also be used to generate split times.
For further details refer to the Lap Beacon manual.
Options
Various options allow the ADL to be configured as a simple stand-alone dash
or to be upgraded to a sophisticated data logging, display and control system.
The options can be enabled at any time by entering a password.
Note that the ADL does not require a Software Update Unit (SUU) to enable
the options, as required by the M4 (pre M4e), M48 & M8 ECUs.
MoTeC Overview 21
See Appendix B: Options Summary for details.
Software
The ADL comes with software packages for managing the ADL, analysing the
logged data and monitoring the telemetry link.
The software must be run on an IBM compatible personal computer running
Windows 95/98/Me/NT/2000/XP.
The following software programs are provided:
Dash Manager
Dash Manager is used for configuration, testing, retrieving the logged data
and for general management of the ADL.
An overview of Dash Manager is included latter in this manual. For detailed
information use the Dash Manager help system.
Interpreter
Interpreter is used to analyse the logged data.
Data Logging analysis is covered in a separate manual.
Telemetry Monitor
The Telemetry Monitor software is used to monitor the optional Telemetry link
and allows viewing of the telemetry data in various graphical formats such as
Charts, Bar Graphs and Dial Gauges. It can also show the vehicles current
track position on a track map and compare the current vehicle data to
reference data.
Alarms can also be set to indicate when a particular value, such as Engine
Temperature exceeds a user programmable limit.
BR2Config
This program is used to configure the BR2 beacon receiver via a CAN
connection. BR2 configuration is covered in the BR2 Manual.
22 Overview
Field Updateable Control Software
The ADL control software (firmware) is field updatable so that new software
features can be used as they become available.
CAN Cable
The CAN Cable allows the computer to communicate with the ADL at high
speed.
The CAN Cable connects between the PC Printer Port (Parallel Port) and the
CAR cable, which is mounted in the vehicle and connects to the ADL.
Be sure that the CAN Cable is connected directly to the PC, do not use an
extension cable or switch box between the PC and the CAN Cable otherwise
incorrect operation may result.
Note that the PC parallel port must be a bidirectional type.
The CAN Cable contains electronics which is powered via the cable from the
ADL.
The CAN Cable can be extended by up to 12 meters. Note that a special 100
ohm data cable is required.
MoTeC Installation 23
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 ADL
has three threaded mounting posts, while the EDL has four mounting holes.
Do not over tighten the mounting screws (to avoid twisting the case).
Vibration isolation may be desirable if the vehicle vibrates severely.
ADL Orientation
For best contrast, the display should be viewed at approximately 20 degrees
above normal, however the ADL will give good contrast between 0 and 40
degrees. Display reflections should also be considered when determining the
mounting angle.
20°
Lighting
The ADL display has excellent visibility in a very wide range of lighting
conditions, however for night time use a front light module is required.
Connector Access
Mount so that the connector may be easily accessed.
