System Overview

The Display 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 Display Logger

ECUs

The C125 Display 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 Display
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 Display 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 add the #29600 C125 I/O enable.

Expanders

E888/E816

The C125 fully supports two E888 or E816 Expanders allowing expansion
of the number of inputs and outputs

Accessories

BR2

A BR2 Beacon Receiver may be connected to the C125, which allows the
Display 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 C125 Display 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 C125 Race Kits.

10 Introduction MoTeC

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 C125 to allow display of any
value that the Display Logger calculates, such as lap times and warning alarm
messages.

The Club Display Logger supports D153, D175 displays which are connected
via CAN.

MoTeC Introduction 11
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 Display Logger.

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 C125 Display Logger.

Installation

This section provides information on how to install the Display 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 Display 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 Display Logger will provide
good contrast between 0 and 40 degrees. Display reflections should also
be considered when determining the mounting angle.

.

The C125 uses a 34 pin connector. See Connector

Function for full details.

and C125 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 Display Logger via a separate switch and a 5 ampere fuse, to
ensure the PC can communicate with the Display Logger without the
need to power the rest of the vehicle.

• The C125 ground must have a direct connection to the vehicle battery.

• The Display Logger is connected to other devices via the CAN bus.

Connecting Devices

Peripheral devices can be directly connected to the Display Logger's input
and output pins. The Display 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 Display 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 MoTeC

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 see Input Characteristics.

Expanders

If additional sensors are required, input expanders can be used, such as
MoTeC’s E816 and 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.

24 Installation MoTeC

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 C125
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
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 Display Logger can only communicate with devices for which it has

the appropriate communications protocol defined.

MoTeC Installation 27
Updating C125 Dash Manager Software

Software updates are available free of charge, giving access to the latest
features. Download the latest software version from the website and follow the
software installation instructions to update to the new version.

To update the associated firmware in the device, select Upgrade Dash
Version from the Online menu. See Configuration Versions and Updating

.

i2 Data Analysis Software

MoTeC's i2 data analysis software is used to analyse the logged data that has

been recorded by the Display Logger. Any number and combination of

graphs, gauges and reports can be analysed simultaneously. The i2

environment can be customised to specific user requirements.

i2 Standard is included with any Data Logging upgrade.

Connecting the Display Logger to a PC

The Display Logger connects to the Ethernet port on the PC. This requires a
connector for the standard Ethernet cable in the loom.

The C125 loom 62204 incorporates this connector. Alternatively the connector
can be wired into an existing loom using the unterminated Ethernet cable
(61131), or the Ethernet to Superseal Connector Cable that is terminated with
Tyco connector pins (61236).

All options are used in conjunction with a standard Ethernet cable.
Connection details are described in PC Connection

PC Communications Setup

To enable PC communications, a connection must be setup in the Dash
Manager software to match the Display Logger serial number.

• On the Tools menu click Connection Settings and then click Add

• Click OK to choose IP (Ethernet). This is the only available connection

type.

• Click Search*

• In the list with discovered devices, click the required Display Logger

and click Select

If the PC needs to communicate with more than one Display Logger, repeat
the steps.

* The connection uses IPV6, which can be affected by firewall and anti
virus applications.

If you have a Display Logger connected but it is not listed in Discovered
Devices, try disabling or uninstalling all anti-virus software.

28 Installation MoTeC

If the Device is 'discovered' without the anti-virus software, you can turn it
back on and put in appropriate exceptions to allow the Display Logger
Manager to communicate with the device.

Only one connection can be active at a time. To switch to a different Display

Logger, click Make Active.
Tip: The current connection is listed at the bottom of the Dash Manager

splash screen (this is the main Dash Manager screen with the picture of the
Logger)

For a quick way to switch between connections

• In the Dash Manager splash screen, enter the connection number
(to enter the splash screen, close all other windows in Dash Manager).

MoTeC Configuration 29

Configuration

All aspects of the Display Logger 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.

The configuration is stored in a file on the PC. When starting Dash Manager
software, the menu items related to changing the configuration are
unavailable. To make them available, load a configuration file either by
opening an existing file or by creating a new one.

All changes to the Display Logger configuration are performed ‘Offline’, i.e.
without the PC communicating with the Display Logger. The changes are
saved in the configuration file on the PC. The file must be sent to the Display
Logger before the changes take effect. See Sending and Retrieving

Configuration Files.

Tip: When using a laptop in and around a car, it is often not practical to use a

mouse to navigate through the program. Using the keyboard to select options
is easier. An overview is given in Windows Keyboard Shortcuts

Configuration Sequence

.

The configuration is best setup in the following order:

1. Connections (Input Pins & Communications)

2. Calculations (Lap Time, Fuel Prediction etc.)

3. Functions (Logging, Display, Alarms, Auxiliary Outputs etc.)

This simplifies the setup procedure by ensuring that the required channels are
available for the functions that use them.

Channels cannot be used until they have been generated by an input,
calculation or function.

Configuration File

From the File menu the following options are available:

• New – creates a new configuration based on a predefined template

• Open – selects an existing file

Right-click the configuration file to Rename, Delete, Send to a disk etc.

• Save – saves a newly created configuration with a meaningful name

• Save as – can be used to create a copy of an existing configuration file

by giving it a new name

30 Configuration MoTeC

• Edit Details – allows for entering event, venue and vehicle details to be

stored with the configuration file

• Check Channels – verifies that all channels are correctly generated

• Edit Configuration Comments – allows for other comments to be

stored with the configuration file

• View Configuration Summary – gives a quick overview of the

configuration file

• Convert Logging Image – allows users to manually convert a log file for
use in i2

• Exit – exits the program

Tip: The most recently used files appear at the bottom of the File menu. This

is often the easiest way to open an existing file.

Backups

Whenever a file is saved, the previous content of the file is saved in the Save
Backups directory. The total number of files is limited to 100.

Channels

Channels are used to convey information between the various systems of the
Display Logger.

For example an input pin may feed a channel called ‘Fuel Pressure’.
This channel may then be used by another system, such as the Di splay
System or Data Logging systems.

The Display Logger channel scheme allows complete flexibility in channel
usage, as any available channel can be used by any other function, i.e. any
channel can be logged, displayed, used in conditions, used in alarms, used as
an input to the user definable tables, etc.

All systems within the Display Logger that generate values must feed one of
the channels.

Pre-defined Channels

MoTeC has defined an extensive list of channels.

General Purpose Channels

Since the use of all channels cannot be predetermined, a number of general
purpose channels have been included for occasions when a suitable
predefined channel is not available.

MoTeC Configuration 31

These general purpose channels may be required when measuring an
uncommon value, or when a general purpose function needs to generate a
special output channel. For example, a 3D table may generate an output
channel to control a valve of some sort, in which case a general purpose
channel may be used and named appropriately.

32 Configuration MoTeC

Channel Properties

Each channel has defined properties, some of which may be modified by the
user. Predefining these properties makes the channels easy to use
throughout the rest of the software.

• Properties that may be modified by the user

o Name

The channel names (and abbreviations) may be changed if necessary.
However name changes should be limited to name preferences rather
than redefining the purpose of the channel, except for the general
purpose channels which may be renamed to suit the current use.

o Abbreviation
o Units (e.g. degrees Celsius, degrees Fahrenheit)

The units for a channel can be selected from a predefined list, for
example the Engine Temperature channel may have units of degrees
Celsius, Fahrenheit or Kelvin. Conversion between units is
automatically handled by the software.

Note: The units are used for display purposes only. This means that

the units can be changed at any time without affecting the calibration of
the channel.

• Fixed properties

o Measurement type (e.g. Temperature)

Defining the measurement type allows the channels to be displayed in
any unit suitable for that type, with automatic conversion between the
units. For example all temperature channels can be displayed in
degrees Celsius, Fahrenheit or Kelvin.

o Resolution

The resolution of all channels is fixed, for example the resolution of the
Engine Temperature channel is fixed at 0.1 °C.
Fixed channel resolutions ensure that the unit conversion system
works properly and that channel comparisons can be performed
correctly.

o Suitable logging rates
o Suitable display filtering
o Minimum and maximum range

MoTeC Configuration 33

Selecting Channels

There are two methods of selecting channels, either the Category Method or
the Search Method.

Category Method

This method divides all the channels into categories and sub categories, so
that the list can be narrowed down to a small list of channels. For example,
the ‘Engine Sensors / Cooling’ category shows a list of channels associated
with the cooling system of the engine.

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 plus sign (+) next to the category name.

34 Configuration MoTeC
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.

Note: The words may be typed out of order so that ‘Engine Oil Temp’ could

be found by typing "temp eng oil" or "oil t eng" or "e o t”
This method is most useful when selecting a channel from the available

channels.

For example, if ‘Engine Temperature’ has been assigned to an input pin, it
can be easily located in the Search list, since this list normally only
contains 50 to 100 items.

MoTeC Configuration 37

Functions

Data Logging (optional)

Data logging allows sensor readings and calculated values to be stored in the

Display Logger's memory for later analysis using the i2 Data Analysis

software.

To configure logging

• On the Functions menu, click Logging

• Select the relevant tabs to set up the logging parameters

Power

The Display Logger power can be turned off at any time without losing the
logged data, because it uses FLASH memory that does not require an internal
battery to keep it alive.

Logging Memory

The C125 has optional Data Logging upgrades providing 120 MB of logging
memory. See Display Logger Upgrades

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.

The Display Logger provides the normal logging type; this will continuously
log data to memory whenever the Start Condition is true and the Stop
Condition is false.

.

Memory Usage

When the logging memory is full the Display Logger 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 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 Dash
Manager software will report the total available logging time.

38 Configuration MoTeC
Logging Setup Files

The logging list can be saved and loaded from a file. This allows multiple
logging setups to be used.

Logging Rate

The logging rate sets how often each channel is logged and can be set
individually for each channel.

The rate at which the values are logged must be fast enough to record all
variations in the reading. If the value is logged too slowly, the readings can be
totally meaningless. For example, suspension position may need to be logged
at 200 times per second or more.

However, 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.

CAN Bus Bandwidth Limit

High logging rates also increase the amount of data that is being received
from the measurement devices, which increases the amount of data on the
CAN bus. This can lead to exceeding the CAN bus bandwidth limit. See

CAN Bus Bandwidth Limit

Note: The Dash Manager software will warn if the bandwidth is likely to be

exceeded.

.

Maximum Logging Rate

The maximum logging rate is limited to the update rate of the particular
channel. This varies significantly depending on the source of the channel.
For example, some communications devices may only update at 50 Hz.
Also some internal calculations may be limited to 100 Hz.

Update Rate

Each input is measured at a maximum rate which is dependent on the
capabilities of the measuring device and may also vary between inputs on that
device. See Update Rate Summary

.

Anti-Alias Filter

If a channel is logged at a rate slower than its specified update rate then an
optional anti-alias filter can be applied.

The anti-alias filter is used to average out any variations in the signal between
logged values. This ensures that unrepresentative values are not logged.

MoTeC Configuration 39

The anti-alias filter is implemented by averaging the channel values between
logging events. For example, if a channel has an update rate of 1000 Hz and
it is logged at 100 Hz then the preceding 10 samples will be averaged each
time it is logged.

The anti-alias filter is normally turned on by default when a channel is added
to the logging list, but may be turned off if required. For normal purposes it is
recommended that the anti-alias filter is left turned on.

Note: For some channels the anti-alias filter cannot be turned on because the

averaging performed by the filter would cause incorrect values. This is the
case for on/off channels and channels where the bit values have a particular
meaning, for example error group channels.

Real Time Value (ADL2, SDL)

For channels that come from an ADL2 or an SDL, the logging anti-alias
filter also affects the real-time value of the channel. This is the value that
all other parts of the system see, such as the various calculations.

Note: The anti-alias filter is limited to 50 Hz for real time values even if the

channel is logged at a lower rate. For example, a channel logged at 10 Hz
will be filtered and updated at 10 Hz in the logging and 50 Hz for the real
time value.

Note: Channels that are not logged are updated at 50 Hz.

Real Time Value (For devices other than ADL2, SDL)

The real time value from other devices and from internal calculations is not
anti-aliased at the logging rate, however the value can be anti-aliased in
the logging.

Phase Shift

The anti-alias filter will cause a phase shift (time delay) of half the logging
rate. For example, a channel logged at 100 Hz is logged every 10
milliseconds, so it is delayed by 5 milliseconds.

For most purposes this time delay is not an issue.
Channels logged at the same rate are delayed by the same amount, which

negates this effect when comparing these channels.
This applies to all channels whether they are generated internally from a

calculation or whether they are generated externally from devices such as
a display device.

40 Configuration MoTeC
Track Map

For the i2 Data Analysis software to plot a track map, either a GPS should be

connected or a number of separate sensors that will provide the required
information.

Track Map using GPS

Ensure GPS Latitude and GPS Longitude are logged.

Track Map using Sensors

The following sensors are required and must be logged:

• Lateral G force (internal sensor)

• Wheel Speed

• Lap Beacon (the ‘Beacon’ Channel must be logged)

• Optionally Longitudinal G force (internal sensor)

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.

MoTeC Configuration 41

Display

The C125 display is a high contrast, high brightness colour LCD display.
The displayed channels and labels are configured on a display style that can

be chosen from a list of predefined styles. Alternatively, a custom display may
be created using the separately purchased Display Creator software. See

Display Creator DBC file setup.

To configure the display

1. On the Functions menu, click Display

2. Select the tab for the required mode (RACE, PRACTICE, WARMUP).

3. Select the required display style.

4. Set the labels and channels you want to display for each of the
numeric displays. To do this double click on the relevant display, or:

a. Select the display.

b. Select the Change button.

42 Configuration MoTeC
Display Modes (Pages)

The display has three display modes; the default names are RACE,
PRACTICE and WARMUP. The mode is changed by pressing the button
assigned to this function.

The mode names can be changed to suit your individual needs; this is done

by double-clicking on the Page Label field.

RACE Page

The Race display is normally used to display minimal information, e.g. RPM,
Lap Time, Fuel Remaining or Laps Remaining.

PRACTICE Page

The Practice display is normally used to display basic information, plus
information to help the driver improve lap times, e.g. Lap Time, Lap
Gain/Loss, Maximum Straight Speed, Minimum Corner Speed or Corner Exit
Speed.

WARMUP Page

The Warm-up display is normally used to display important engine sensor
readings during engine warm-up, e.g. RPM, Battery Voltage, Engine
Temperature, Oil Pressure, Oil Temperature and Fuel Pressure.

Gain / Loss Bar

The Gain / Loss bar can be configured to graphically represent the current
value of the Lap Gain/Loss Running channel. If not configured the Gain / Loss
Bar does not display.

Example Bar / Loss Bar

This bar can be customised to suit a user's preference. For example:

• Setting the scale and the time units.

• Customise the labels at either end of the bar (in the example above, Left

and Right is used, another example is +2 and -2, where 2 is the scaling
value).

• Invert colours, that is - red or green on either side.

• Specify the negative to the left or right.

MoTeC Configuration 43
Dial or Bar Graph (depending on style chosen)

Example dial

Example sweep bar

Example linear bar

The dial or bar graph has a user definable range and is typically used as a
tacho, however it can be used to display any other value.

A fully programmable shift point can be displayed, which can also be gear
dependent.

44 Configuration MoTeC
Top Displays

The three numeric displays shown above can be programmed to display any
channel value.

The numeric displays can show any channel value plus up to two override
values. Override values display each time their value is updated. This is
useful for values that are updated periodically. 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.

The label above each of the numeric displays can be changed to suit the
channel assigned.

MoTeC Configuration 45
Centre Display

The centre display is normally used to display the current gear but can be
used for other purposes.

Bottom Display

46 Configuration MoTeC

At the bottom, up to 20 lines can be accommodated, with each line containing
up to 3 channel values at a time.

The label above each value can be changed to suit the channel assigned.
The 20 lines can be scrolled up or down using external buttons.
Similar to the top numeric displays, the bottom display can show up to four

override values.

Four Line Style

Where the four line style is chosen, it shows four lines of values at a time, with
up to three values per line.
The 20 lines can be scrolled up or down, 4 lines at a time, using external

buttons.

Alarms

Any alarms generated are displayed at the bottom of the display. The active
alarm message displays across the complete row, overriding all other values
until the alarm is acknowledged. To draw the driver's attention to the display,
it is recommended to activate a warning light.

The message can be defined as required and can 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.

MoTeC Configuration 47

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 the second time the alarm activates at
100 °C. A limit may be set on the number of times the comparison value is
allowed to increment. An alarm may return to its original value after a period
of time, in case the alarm condition was temporary.

The alarms can be dependent on the current display Mode (for example
Warm-up, Practice or Race).

Display Formatting

Units

All display units can be changed to suit the driver preferences, for example,
show temperatures in Fahrenheit rather than in Celsius.

Note: 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.

Display Creator DBC File Setup

When using Display Creator, communications and channels need to be set
up. To automate this, a DBC file is created when the Dash Manager
configuration is saved. This file can then be imported into Display Creator.

The Display Creator Channels and Display Creator Settings tabs are used to
set the definitions for creation of the DBC file. This file is then imported into
DisplayCreator to automate the communications and channels setup.

Display Creator Channels tab

This tab is used to select the channels to include in the DBC file. The DBC file
is created when the configuration is saved.

The DBC file is imported by Display Creator to automate the setup of
communications and channels.

Note: Channels selected in the Display Creator Setting tab must also be

selected in this list for them to be included in the DBC file.

48 Configuration MoTeC

Display Creator Settings tab

Other Functions

The Display Logger can perform many other functions accessible from the
Functions menu including the following:

Shift Lights – to configure the shift point values for use with the Shift Lights.
Shift Light Module – to configure the C125 10 stage shift lights as well as an

additional MoTeC's SLM-C or SLM.

MoTeC Operation 49

Operation

When operating the C125, any of the activities of the Online menu of the

Display Logger Manager software can be performed. This requires the PC to
communicate to the Display Logger.

Note: All other menu items perform offline activities.

Retrieving the Logged Data

• On the Online menu, click Get Logged Data

A PC is used to unload the logged data from the Display Logger. The logged
data is then stored on the computer's hard disk.

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's hard disk. In this case the
Display Logger 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.

Sending and Retrieving Configuration Files

• On the Online menu, click Send Configuration to send the currently

open configuration file

Note: When a configuration file is sent to the Display Logger the
existing data is retrieved and stored in the From Dash Backups

directory to use in case the data in the Display Logger needs to be
restored. The maximum number of files is 10.

• On the Online menu, click Get Configuration to retrieve the current

configuration file.
This will only be necessary if the original file is not available on the PC.

Zeroing Sensors

Some sensors require regular zeroing, for example Steering Angle,
Suspension Position, Ride Heights, G Force Sensors and Throttle Position.
Dash Manager software provides a feature for easy zeroing of all these
sensors.

50 Operation MoTeC

Checking Operation

Monitor Channels

The currently active channels can be monitored to check the operation of all
functions and measurements.

• On the Online menu, click Monitor Channels

• To show any channel on an oscilloscope style screen, click Utilities

and then Oscilloscope

Simulate

The Simulate feature allows most input channels to be manually changed so
that the Display Logger operation can be checked under abnormal conditions,
e.g. High Engine Temp. This is extremely useful for checking that the Display
Logger is working as expected.

• On the Online menu, click Simulate

Test

A number of tests are provided to check the operation of the Display Logger,
such as the Display test.

• On the Online menu click the appropriate test

Configuration Versions and Updating

• On the Online menu, click Upgrade Dash Version

The software inside the Display Logger (firmware) can be updated by the user
at any time to take advantage of the latest features.

Matching Versions

The firmware version must match the version of the Dash Manager software
on the PC in order to communicate. Dash Manager will show a warning if the
versions do not match.

Tip:
To check the version of Dash Manager, click About MoTeC C125 Dash
Manager on the Help menu.

The firmware version is displayed on the bottom line of the display for two
seconds when the Display Logger is powered.

Matching Configuration File

The configuration file must also match the software and firmware versions
used. The display will show a warning if the file does not match.

MoTeC Operation 51

Configuration files can be updated by choosing the option to automatically
update the configuration file while updating the software (firmware). It can
also be done manually by upgrading the configuration file and sending it to
the Display Logger:

• On the File menu, click Open

• In the Files of type box select the new version file extension.

The file will be converted to the new version format and saved with the
same file name but with the new version file extension.

Note: The old file is not changed.

• On the Online menu, click Send Configuration to send the

configuration file to the Display Logger

Upgrading the Display Logger

Several options are available as upgrades to customise and grow your
system.

The currently enabled options can be listed and new options can be activated
through a password acquired from MoTeC.

To Upgrade the Display Logger

• On the Online menu, click Enable Dash Options

Password Protection

• On the Online menu, click Set Access Passwords

Several Display Logger capabilities can be protected from unauthorised
access by using the password protection.

Note: Ensure you keep passwords secure. The unit needs to be returned to

MoTeC for unlocking if the passwords are lost.

Other Online Activities

Many other activities are accessible from the Online menu including the

following:

Reference Lap – to send a reference lap to the Display Logger used in
the lap gain/loss system.

View – to view:

o saved details e.g. Running Totals
o Device Halt Counts

Communication – to list the current Connections Settings
Miscellaneous

CAN Bus Wiring Requirements

• The CAN bus should consist of a twisted pair trunk with 100R (0.25 watt)
terminating resistors at each end.

o If the CAN bus is less than 2 metres (7 ft) long, a single termination

resistor may be used.

• The preferred cable for the trunk is 100R data cable.

• The maximum length of the bus is 16 metres (50 ft)

• CAN devices (such as MoTeC Display Loggers, ECUs etc.) may be

connected to the trunk with up to 500 mm (20 in) of twisted wire.

MoTeC Appendices 69

C125 Display Logger to ECU wiring (RS232)

The following details the methods for connecting the Data Logger to various
MoTeC ECUs 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 Data Logger 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.

M4e

Note:

• Older M4 ECUs require a different connection method

• The data to the Display Logger will be interrupted while a PC is

connected.

M48, M4 (pre M4e) and M8

The M48, M8 and M4 (pre M4e) require the use of a CIM module or a PCI
Cable to convert the logic level signals used by these ECUs into RS232
levels.

Using a CIM Module

Contact MoTeC for the CIM module drawing for full wiring details.

Note:

• The data stream to the Display Logger will be interrupted while a PC is
connected.

Comms Error Codes

The "Comms CAN x Diagnostic" and "Comms RS232 Diagnostic" channels
can be used to diagnose communications problems.

Multiple errors are shown by error codes added together. For example:
A RS232 error of 9 = parity + overrun.

The error values have the following definitions:

RS232 Errors

Errors generated by RS232 communications.

1 PARITY Parity bit incorrect. The comms parity setup is

wrong, or there is electrical interference causing
errors in the data.

2 FRAMING Not seeing the stop bit. The baud rate or stop

bit setup is wrong or there is electrical
interference causing errors in the data.

4 NOISE Glitch in the data. Electrical interference is

causing glitches in the signal. (the Display
Logger does not generate this error)

8 OVERRUN A byte was received before the previous byte

was read indicating that the processor was too
busy to read the message.

512 NO DATA A valid message header was not found - either

there is a wiring fault or comms is setup
incorrectly.

1024 CHECKSUM A valid message header was found, but the

checksum was wrong. If seen in combination
with other errors there is electrical noise. If only
checksum errors occur there may be a
software incompatibility between the Display
Logger and the other device.

2048 WRONG DATA Could not decode the protocol.

MoTeC Appendices 77
General CAN Errors

Errors generated by general CAN communications.

2 FRAMING Only generated when used with an

E888/E816 expander. Inconsistent message
length.

8 OVERRUN Receive or transmit overrun error. In the

receive case a byte was received before the
previous byte was read indicating that the
processor is too busy to read the message.
In the transmit case the transmit buffer is full
which could happen if the CAN bus is too
busy.

256 BAD CONFIG The device configuration is not valid (e.g.

overlapping CAN addresses)

512 NO DATA A valid message header was not found -

either there is a wiring fault or comms is
setup incorrectly, (problem could be at either
end), e.g. transmit and receive CAN IDs do
not match.

1024 CHECKSUM Only generated when used with an Async

Expander. See RS232 Errors

.

2048 WRONG DATA Only generated when used with an Async

Expander or E888/E816 Expander. Async
Expander: Could not decode the protocol.
E888/E816: Compound ID incorrect.

4096 BUS WARNING More than 96 errors have occurred on the

CAN bus. Check wiring and termination
resistors. The CAN bus may still be
operational.

8192 BUS OFF More than 255 errors have occurred on the

CAN bus. CAN communications is
