System Overview
The Dash Logger offers extensive possibilities to integrate with ECUs,
peripheral devices and accessories to form a complete solution that powers,
controls, logs, monitors and communicates virtually any automotive
parameter.
Typical devices used with the Dash Logger
ECUs
The CDL3 Dash Logger can be connected to all MoTeC engine management
systems and some other manufacturers' ECUs either via CAN, RS232 or
OBD-II. This avoids duplication of sensors and allows the Dash Logger to
display and log many ECU parameters.
The typical update rate is about 20 times per second for RS232 and 50 times
per second for CAN, but is less from OBD-II.
MoTeC Introduction 9
Sensors
The optional Dash Logger inputs* can be connected to a wide variety of
sensors. Different types of sensors are available to suit different types of
measurements, for example: temperature, pressure, movement etc.
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 which may be measured by an Analogue Temperature input.
However most wheel speed sensors generate a variable frequency signal
which must be connected to either a Digital input or a Speed input.
*To use these inputs, you will need to enable the #29500 CDL3 12 I/O
upgrade.
Expanders
E888
The CDL3 supports an E888 Expander, 8 thermocouples only.
Accessories
BR2
A BR2 Beacon Receiver may be connected to the CDL3, which allows the
Dash Logger to calculate lap times for display and to provide lap
information for the data analysis software.
SLM-C
The SLM-C Club Shift Light Module can be used for shift lights, warning
lights and other driver alerts.
The SLM-C includes 8 coloured LEDs that can be programmed to display
in a pre-defined pattern.
GPS
The CDL3 Dash Logger supports many GPS (Global Positioning System)
devices allowing it to record speed and position information as well as
providing lap timing.
This information can be used in the i2 data analysis software to create
track maps, and plot and compare driven lines.
A 10 Hz GPS is supplied as part of the CDL3 Track Kits.
10 Introduction
Video
MoTeC’s Video Capture System (VCS) is an integrated in-car camera
system, recording video and audio using the MPEG-2 video compression
format at broadcast quality. It includes a built in real-time graphics
processor that allows sensor data to be overlaid onto the video in real-time
without the need for additional hardware. The CAN interface enables
communication with other devices, for example to set Auto Start/Stop
Recording conditions and synchronisation.
Multiple video streams, from in-car cameras for example, can be linked
with logged data for synchronised playback of footage alongside other
analysis components.
Note: Synchronisation can be completed manually or automated by using
the CAN Video Sync feature.
Lambda Measurement
PLM
The PLM Professional Lambda Meter measures the air fuel ratio over a
wide range of mixtures with fast response time. It is compatible with Bosch
LSU and NTK UEGO Lambda sensors and displays the Lambda readings
via the integrated display.
LTC/LTCD/LTC NTK
LTC Lambda to CAN modules provide accurate Lambda measurements
even when the exhaust gas temperature changes rapidly. They are
compatible with the Bosch LSU 4.9 / NTK Lambda sensors and transmit
Lambda readings via the CAN bus.
Remote Displays
A remote display device may be connected to the CDL3 to allow display of
any value that the Dash Logger calculates, such as lap times and warning
alarm messages.
The Club Dash Logger supports MDD displays which are connected via CAN.
PDMs
Power Distribution Modules are designed to replace conventional relays,
fuses and circuit breakers by providing electronically switched power to the
various electrical systems in the vehicle. This simplifies wiring and switch
requirements, while increasing reliability.
Full diagnostic information, including output currents and error status, can be
transmitted via CAN to the Dash Logger.
MoTeC Introduction 11
Several models are available to suit vehicles with different complexity ranging
from 15 to 32 outputs and 12 to 23 inputs.
Other Devices
Many other devices can be connected to the CDL3 Dash Logger.

Installation
This section provides information on how to install the Dash Logger in the
vehicle and connect it to other devices. It will also provide information on how
to install the software.
Mounting and Wiring
The Dash Logger has three threaded mounting posts. For further details see
Mounting Dimensions
Mounting Tips
• Avoid twisting the case: use washers between the unit and the mounting
panel to ensure that the unit is mounted only at the mounting points and
do not over tighten the mounting screws.
• Vibration isolation may be desirable if the vehicle vibrates severely.
• Mount so that the connector may be easily accessed.
• Orientation: for best contrast, the display should be viewed at an angle of
approximately 20 degrees, however the Dash Logger will provide good
contrast between 0 and 40 degrees. Display reflections should also be
considered when determining the mounting angle.
The CDL3 uses a 34 pin connector. See Connector
Function for full details.
and CDL3 Pin List By
Wiring Tips
• To ensure that the connector is sealed, plug unused holes with filler plugs.
• Use 22# Tefzel wire (Mil Spec M22759/16-22) (5 A max at 100 C)
• 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 21
• Some sensor connectors may not be available with 22# terminals, in
which case doubling the wire over gives the equivalent of an 18# wire.
This is suitable for many of the common sensor terminals.
• Use the correct crimping tool for all contacts to ensure a reliable
connection.
• Power the Dash Logger via a separate switch and a 5 ampere fuse, to
ensure the PC can communicate with the Dash Logger without the need
to power the rest of the vehicle.
• The CDL3 ground must have a direct connection to the vehicle battery.
• The Dash Logger is connected to other devices via the CAN bus.
Connecting Devices
Peripheral devices can be directly connected to the Dash Logger's input and
output pins. The Dash Logger can also send or receive data from other
devices via either RS232 or CAN communications.
Inputs – Requires I/O Upgrade
Input Types
A range of sensors is available to suit different types of measurement, e.g.
temperatures, pressures, speed. Each type of measurement generates a
different electrical signal that requires a suitable input type.
Each sensor needs to be connected to the type of input designed to suit that
type of sensor.
MoTeC devices have the following input types available:
• Analogue Voltage Inputs
• Analogue Temperature Inputs
• Digital Inputs
• Wheel Speed Inputs
In addition to sensors connected to the inputs, the Dash Logger has internal
sensors available for battery voltage, device temperature and G-force.
Analogue Voltage Inputs
Analogue Voltage inputs are normally used to measure the signals from
analogue voltage type sensors, i.e. sensors with variable voltage outputs,
such as:
o Rotary or linear potentiometers
22 Installation
o Signal conditioned three-wire pressure sensors
o Thermocouple amplifiers
o Accelerometers
These inputs can also be used to measure two-wire variable resistance
sensors if an external pull-up resistor is connected from the input to the
5 V sensor supply.
Additionally, on/off switch signals may be connected, which may also
require an external pull-up resistor.
Analogue Temp Inputs
Analogue Temperature inputs are identical to Analogue Voltage inputs,
except that they contain a 1000 ohm resistor which is connected internally
from the input pin to the 5 V sensor supply. This allows the Analogue
Temperature inputs to be used with two-wire variable resistance sensors,
such as:
o Two wire thermistor temperature sensors
o 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 (e.g. MoTeC
Thermocouple Amplifier).
Additionally, on/off switch signals may be connected.
Digital Inputs
Digital inputs can be used for the external switches required to operate the
display. These inputs have a 4700 ohm resistor connected internally from
the input pin to the 5 V sensor supply so that a switch can be simply
connected between the input pin and 0 V.
They can also be connected to a brake switch or other switch.
Digital Inputs include the following measurement methods:
o Frequency: The frequency of the input signal is measured
o Period: The time between successive pulses is measured
o Pulse width: The low time of the pulse is measured
o Count: Counts the number of pulses
o Phase Difference: Calculates the phase difference between two digital
inputs
o Beacon: For connection of a lap beacon
MoTeC Installation 23
Speed Inputs
Speed Inputs are identical to 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 changes 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.
The Pulse Width method measures the high time of the pulse rather than
the low time as measured by the Digital Inputs.
Input Specifications
For full specifications refer to Input Characteristics
Expanders
If additional sensors are required, input expanders can be used, such as
MoTeC’s E888. Sensors can be connected to the expander inputs and
communicate via either RS232 or CAN. See Configuring Communications
Outputs – Requires I/O Upgrade
Auxiliary Outputs are used to control various vehicle functions, for example:
o Gear Change Lights
o Warning Lights
o Relays controlling Thermatic Fans and Pumps etc.
Note: Devices that consume more than the maximum current (e.g. motors)
should be driven via a relay or a MoTeC PDM (Power Distribution Module).
Output Specifications
Full specifications can be found in Output Characteristics.
Expanders
If additional outputs are required, output expanders can be used, e.g. PDM.
Expander outputs can perform the same tasks as the device outputs and can
be driven by communication via either RS232 or CAN. See Configuring
Communications.
Communications
Communications are used to send and receive data from one device to
another. There are two communication protocols: RS232 and CAN. Generally
older devices use RS232 and newer devices use CAN.

CAN (Controller Area Network) Communications
This protocol enables communication between all devices connected to the
same bus. The CAN bus allows for communicating at high speeds. The CDL3
has two independent CAN communications ports that can be connected to
other devices with a compatible CAN port. The bus speed for each interface
can be set independently.
Typical MoTeC devices communicating over CAN:
o M84 and 'Hundred Series' ECUs: M400, M600, M800, M880
o Shift Light Module: SLM, SLM-C
o Lambda meters: LTCs, PLM
o Expanders and input modules: E888, PDM
o Displays: SDL3
o Beacon receiver: BR2
These devices communicate at 1 Mbit/sec, so any other devices connected
on the CAN bus must also communicate at 1 Mbit/sec. If a device
communicates at another speed, it should be wired to the other CAN bus, and
the speed of that CAN bus must be set to match the speed of the device.
RS232 Serial Communications
This is a one to one protocol, communicating from one device to one other
device. Typical devices communicating over RS232:
o MoTeC M4, M48 ECUs
o Radio telemetry device
o Global positioning system: GPS
Note: The Dash Logger can only communicate with devices for which it has
the appropriate communications protocol defined.
