MoTeC Introduction 1
Introduction
The MoTeC MDD is a small satellite display for use with the MoTeC Advanced
Dash Logger (ADL) or a MoTeC ECU.
The MDD is small enough to mount on the vehicle steering wheel or it may be
mounted in a more conventional position.
When used with an ADL it is normally used with a “Blind” ADL (an ADL with no
display).
The MDD receives data from the ADL or M800 via CAN (Controller Area
Network). It can also receive data from an M4, M48 or M8 ECU via a serial
link.
Display
The display is a dot matrix backlit graphics LCD which allows the MDD to
support a number of different display layouts to suit varied applications and
make best use of the limited display area.
Backlight Brightness
The LCD backlight brightness may be remotely adjusted when the MDD is
used with an ADL. See the ADL Operation section for further details.
The brightness is not adjustable when used with an ECU.
Contrast
The display contrast is adjusted at manufacture and does not normally need to
be changed.
Mounting
The MDD should be mounted using double sided adhesive tape or a rear
panel fitted with mounting holes may be used.
2 Introduction
Firmware Version
The program inside the MDD is called “firmware”. The firmware determines the
capabilities of the MDD.
This document is current for firmware version V1.18
Updating the Firmware Version
Over time newer firmware versions will be released that may have additional
capabilities or display layouts.
Updating the firmware requires special equipment. This can be performed by
the MoTeC dealers listed below:
• MoTeC Pty Ltd Australia
• MoTeC Systems USA
• MoTeC Europe Ltd
• MoTeC Japan
• MoTeC Queensland
MoTeC ADL Operation 3
ADL Operation
This section describes using the MDD with a MoTeC ADL.
ADL Version
For compatibility with MDD V1.18, (or later) the ADL must be running version
3.00M or later firmware.
Wiring
The MDD communicates with the ADL via a CAN connection. See Appendix
H: Wiring to ADL for wiring details. A correctly configured ADL will be
automatically detected by the MDD when powered up.
Display Layouts
A number of different display layouts are available. The display layout is
selected by loading the appropriate MDD CAN template in the Inputs |
Communications section of Dash Manager.
The various display layouts are described in the following section.
Backlight Brightness
The LCD backlight brightness may be remotely adjusted with data received
from the ADL. This information can be provided by an ADL which is using the
appropriate Comms template to transmit a channel with the brightness value.
Each of the layouts comes with a second template that includes Backlight
Brightness. This allows the brightness of the MDD display to be controlled by
generating the “MDD Backlight Brightness” channel in the ADL.
The channel is a percentage value – note that if this channel has a value of 0,
the MDD will default to full brightness.
The channel can come from any source; a fixed value, a potentiometer
connected to an input pin, from channel maths, etc as long as the required
channel is generated.
If the backlight brightness is not controlled by the ADL the MDD uses a default
backlight brightness (less than maximum) which should suit most applications.
At the default brightness the display illumination will be consistent for battery
4 ADL Operation
voltages between 8V and 15V. When full brightness is selected then the
intensity will reduce when battery voltage is below 12V
1. Full ADL Display
This layout allows the MDD to mimic all standard features present on the ADL
display with the exception of the enunciator for the top numeric display.
The ADL Race/Practice/Warm-up display modes can be used to configure 3
different layouts.
The implementation of time formats on the MDD display is more flexible than
the ADL display – time channels with resolution of 1, 0.1 and 0.01 seconds
can be correctly displayed on the left and right numeric.
Example
Displayed Channels
The channels displayed should be configured in the ADL Display setup.
Enunciators
The enunciators displayed for the left and right numerics are taken from the
enunciators configured on the ADL. The MDD includes some enunciator
combinations that are not available on the ADL. These are listed in Appendix
C: Special Enunciator Strings.
ADL Comms Configuration
In the ADL Inputs | Communications setup select the “MDD Transmit (ADL
Display)” CAN template. Note that any vacant CAN Tab may be used.

2. Gain Loss Layout for ADL
This display layout shows a ‘Lap Gain Loss’ bar graph at the top of the display
and also includes the ADL left, right centre, and bottom displays.
The Gain Loss bar graph is based on the ADL top numeric.
The normal ADL bar graph is not shown
The ADL Race/Practice/Warm-up display modes can be used to show
different channels.
Example
Displayed Channels
The channels displayed should be configured in the ADL Display setup.
Enunciators
The MDD includes some enunciator combinations that are not available on the
ADL. These are listed in Appendix C: Special Enunciator Strings.
ADL Comms Configuration
In the ADL Inputs | Communications setup select the “MDD Transmit (Gain
Loss Display)” CAN template. Note that any vacant CAN Tab may be used.
MoTeC ADL Operation 7
Gain/Loss functionality
The gain/loss bar-graph uses the data from the ADL Top Numeric.
The bar-graph has 100 segments with 50 segment to the left of center and 50
segments to the right. Each segment represents one least significant digit of
the value displayed in the ADL top numeric.
For example if the Lap Gain Loss channel is displayed with two decimal places
on the ADL top numeric then each segment will represent 0.01 seconds giving
a maximum range of ±0.50 seconds.
To optimise the display the Lap Gain Loss channel may need to be rescaled.
For example if a range of ± 0.25 seconds is required than the Lap Gain Loss
channel will need to be multiplied by two. This can be done in the ADL by
feeding the Lap Gain Loss channel into Channel Maths which can then
generate a new channel that is multiplied by two.
Note that the ADL Top Numeric itself will not display a negative value, but
negative values will be displayed on the MDD bar graph.

3. Large Numeric Layout for ADL
This layout displays two values in a large font for maximum readability. It also
displays the ADL bottom line.
It does not show the ADL bar graph, centre numeric or top numeric.
The ADL Race/Practice/Warm-up display modes can be used to show
different channels.
Example
ADL Display Mode
ADL left numeric and enunciator
ADL right numeric and enunciator
ADL Bottom Line
Displayed Channels
The channels displayed should be configured in the ADL Display setup.
Enunciators
The MDD includes some enunciator combinations that are not available on the
ADL. These are listed in Appendix C: Special Enunciator Strings.
ADL Comms Configuration
In the ADL Inputs | Communications setup select the “MDD Transmit (Large
Numeric)” CAN template. Note that any vacant CAN Tab may be used.
MoTeC ADL Operation 9
4. Lap Display Layout for ADL
The Lap Display layout shows Lap Time and Number and optionally, Predicted
Lap Time or Lap Time Gain Loss. It also mimics the Bottom line of the
standard ADL display.
Note that this display layout is an older style layout that was designed for a
special racing category. It is normally easier to use one of the other layouts.
The normal ADL Race/Practice/Warm-up display modes can be used to show
different channels.
Example:
The example below shows Lap Time and Number and the Bottom Line. Other
display configurations are also possible.
} ADL Top Numeric and label
} ADL Left Numeric and
ADL Bottom Line
Displayed Channels
The channels displayed should be configured in the ADL Display setup.
In the example above the ADL Display setup is configured as follows:
ADL Top Numeric: “Lap Number” with format = Decimal
ADL Left Numeric: “Lap Time” with format = SS.HH
Bottom Line: Will mimic the ADL bottom line
ADL Comms Configuration
In the ADL Inputs | Communications setup select the “MDD Transmit (Lap
Display)” CAN template. Note that any vacant CAN Tab may be used.
10 ADL Operation
Detailed Setup
The following describes how the “Lap Display” layout treats the ADL display
setup. Note that slightly different Layout and Labelling will be used depending
on the setup as described below.
MDD Gain / Loss Bar Graph
If the ADL Right Numeric is visible and is in decimal format then the
gain/loss bar graph will be displayed. The range is ± 0.40 sec if
displaying a channel with resolution of 0.01 sec such as the “Lap Time
Gain/ Loss” channel. Note that this bar graph may be turned off by
leaving the Right Numeric setup blank.
MDD Upper Location
If the ADL Top Numeric value is visible then the value will be displayed
in the upper location. If the value format is decimal then the “Lap
Number” label will be displayed, otherwise “Fastest Lap” will be
displayed.
MDD Lower Location
If the ADL Left Numeric is visible then the value will be displayed in the
lower location. If the format is a time format (SS.HH or M:SS.HH) then
the “Lap Time” label will be displayed otherwise a label will not be
displayed.
If the ADL Right Numeric is visible and is NOT in decimal format and the
ADL Left Numeric is NOT visible the value will be displayed in the lower
location and “Predicted Lap” will be displayed. Note that this is normally
used with the ADL Left Numeric configured as an override so that when
the override value is removed the Predicted Lap Time is displayed.
MDD Bottom Location
The MDD bottom location mimics the ADL Bottom line.
MoTeC ADL Operation 11
5. Vertical Bar Graph Layout for ADL
This layout displays 8 channels of data into vertical bar graphs, scaled within a
range set by the user. It is also possible to display two marker lines and
values.
This layout would typically be used to display 8 Exhaust Gas Temperatures,
but can be configured to display other channel values.
The layout is not based on the ADL display setup, and so will not change
when the ADL display mode changes.
Example
Maximum
Marker 1
Marker 2
Minimum
The eight bar graph values and the two marker positions are scaled according
to the Maximum and Minimum values received from the ADL, within a range of
-999 to 9999.
Markers
Marker numerics move with the marker dots, and are shown if they are within
range and do not obscure the Maximum and Minimum numerics. A marker can
be removed from the screen by sending a marker value outside of the
displayed range.
ADL Comms Configuration
Unlike most other display layouts, the bar graph displays require two CAN
templates to be selected.
The first is ‘MDD Transmit (Vertical Bar Graph)’ which sets the display layout.
12 ADL Operation
The second template contains the channels to be sent. While these can be
configured by the user, included with Dash Manager is a template that
contains 8 Exhaust Gas Temperature channels. For this option, choose a
second (blank) CAN tab and select the comms template ‘MDD Transmit (8 x
EGT)’
If different channels are to be displayed, first select the EGT template then
change the EGT channels to the required channels. Do not change any of the
other channels and do not modify any other values.
Channels Required
The Minimum, Maximum, Marker values and the “Display Markers Text” flag
must be generated in the ADL configuration so that they can be transmitted to
the MDD.
The “Display Markers text” flag should be set to 1 if the marker values are to
be shown, otherwise it should be set to zero.
If these values are to be fixed, or rarely changed, then a value may be
assigned in the Inputs | Remote Control screen. The desired value should be
set in the Initial Value. The Default Value is not used and should generally be
set to zero. The appropriate channels can be found in the MDD Channels |
MDD Control category.
MoTeC ADL Operation 13
6. Horizontal Bar Graph Layout for ADL
This layout displays 8 channels of data into horizontal bar graphs, scaled
within a range set by the user. It is also possible to display two markers lines
and values.
This layout would typically be used to display 8 Exhaust Gas Temperatures,
but can be configured to display other channel values.
The layout is not based on the ADL display setup, and so will not change
when the ADL display mode changes.
Example
Bar values
Minimum
Marker 1
value
The eight bar graph values and the two marker positions are scaled according
to the Maximum and Minimum values received from the ADL, within a range of
-999 to 9999.
Marker 2
value
Maximum
Markers
Marker numerics do not move with the marker dots, and may be hidden or
displayed according to a flag in the user CAN messages. The marker dots can
be removed from the screen by sending a marker value outside of the
displayed range.
ADL Comms Configuration
Unlike most other display layouts, the bar graph displays require two CAN
templates to be selected.
The first is ‘MDD Transmit (Horizontal Bar Graph)’ which sets the display
layout.
