System Overview

The Displ ay Logger offers extensive possibilities to integrate with ECUs,
peripheral devices and accessori es to form a complete soluti on that powers,
control s, logs, m onitors and comm unic ates virtually any automotive
parameter.

Typical devices used with the Display Logger

ECUs

The C125 Di spl ay Logger can be connected to all MoTeC engine
management systems and some other manufac turers' 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 CA N, but is le ss from OBD -II.

MoTeC Introduction 9
Sensors

The optional Display Logger inputs* can be connect ed to a wide vari ety of
sensors. Different types of sensors are available to suit different types of
measurem ents, for example: temper ature, pressure, movem ent et c .

Sensors conver t a physical measurement (e.g. pressure) into an electrical
signal (e.g. volts).

Diff er ent types of sensors gener ate different types of electrical signals. For
example, most temperatur e sensors convert the temperature into a variable
resistance whic h m ay be m easured by an A nalogue Temperatur e input.
However most wheel speed sensor s generat e a variable frequency signal
which must be connec ted 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 full y supports two E888 or E816 Expanders allowing expansion
of the number of input s and outputs

Accessories

BR2

A BR2 Beacon Receiver m ay be connected to the C125, which allows the
Display Logger to calculate lap times for display and to provide lap
inform ation for the data analy si s software.

SLM-C

The SLM-C Club Shift Light Module can be used for shift lights, warning
lights and other dr iver alerts.

The SLM-C includes 8 coloured LEDs that can be program med to display
in a pre-defined pattern.

GPS

The C125 Di spl ay Logger supports many GPS (Global Positioning
System) devices allowing it to rec or d speed and posit ion inform ation as
well as providing lap timing.

This inform ation can be used in the i2 data analysis software to cr eate
track maps, and plot and compare driv en lines.

A 10 Hz GPS is supplied as part of t he C125 Race Kits.

Installation

This secti on pr ov ides i nformation 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 t he software.

Mounting and Wiring

The Display Logger has three t hr eaded m ounting posts. F or further details
see

Mounting Dimensions.

Mounti ng Tips

• Avoid twisting the case: use washers between the unit and the mounting
panel to ensure that the unit is mounted onl y 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 t he connect or m ay be easily accessed.

• Orientati on: for best contrast, the display should be v iewed at an angle

of approximately 20 degrees, however the Di spl ay Logger will provide
good contrast between 0 and 40 degr ees. Display ref lections should also
be considered when determining the mounting angle.

The C125 uses a 34 pi n c onnec tor. See

Connector and C125 Pi n List by

Function for full details.

Wiring Tips

• To ensure that t he c onnec tor is sealed, plug unused holes with filler
plugs.

• Use 22# Tefzel wir e (Mil Spec M 22759/16-22) (5 A max at 100 C)

• Tefzel wire is difficult to stri p unless the corr ec t stripping tool i s used.

• Be careful not to nick the wires as thi s may result in wire failur e or poor

crimping.

MoTeC Installation 21

• Some sensor connector s may not be available with 22# terminals, in
which case doubling the wire over gives the equivalent of an 18# wire.
This is suit able for many of the common sensor termi nals.

• Use the correct c rimping tool for all cont ac ts to ensure a reliable
connection.

• Power the Display Logger via a separate switch and a 5 am per e fuse, t o
ensure the PC can communic ate with the Display Logger without the
need to power the rest of t he v ehicl e.

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

• The Displ ay Logger i s connected to other devices vi a the CAN bus.

Connecting Devices

Peripheral dev ices can be directl y connected to the Display Logger's input
and output pi ns. The Display Logger can also send or receive data from other
devices vi a either RS232 or CAN communications.

Inputs – Requires I/O Upgrade

Input Types

A range of sensors is av ailable to suit differ ent types of measurement, e.g.
temperatur es, pr essures, speed. Each t y pe of measure ment generates a
diff er ent electrical signal t hat requires a suitabl e input type.

Each sensor needs to be connec ted to the type of input designed to sui t that
type of sensor.

MoTeC devices hav e the f ollowing input types av ailable:

• Analogue Volt age Inputs

• Analogue Temperature Inputs

• Digital I nputs

• Wheel Speed Inputs

In additi on to sensors connect ed to the inputs, the Display Logger has internal
sensors available for battery v oltage, dev ic e temperature and G-force.

Analogue Voltage Inputs

Analogue Volt age inputs are normally used to m easure t he si gnals from
analogue v oltage type sensors, i. e. sensors with variable v oltage outputs,
such as:

o Rotary or linear potenti om eters

22 Installation MoTeC

o Signal conditi oned three-wire pressure sensors
o Thermocouple amplifiers
o Accelerometers

These inputs can al so be used to measure two-wire variable resistance
sensors if an exter nal pull-up resistor is connected from the input to the
5 V sensor supply.

Additionally, on/off switc h si gnals may be connected, which m ay al so
require an external pull-up resistor.

Analogue Temp Inputs

Analogue Tem per ature inputs are identical to Analogue Voltage inputs,
except that t hey c ontain a 1000 ohm resistor which i s connected internall y
from the input pin to the 5 V sensor supply. This allows the Analogue
Temperatur e inputs to be used with two-wire v ari able resistance sensors,
such as:

o Two wir e thermistor temperature sensors
o Two wir e variabl e r esi stanc e pr essure sen sors

Some voltage out put sensors can also be used if t hey can driv e the 1000
ohm resistor without causing an error in their reading (e.g. MoTeC
Thermocouple Amplifier ).

Additionally, on/off switc h si gnals may be connected.

Digital Inputs

Digital inputs can be used for the exter nal switc hes req uired to oper ate the
display. These inputs have a 4700 ohm resistor connec ted internall y from
the input pi n to the 5 V sensor supply so that a switc h c an be si mply
connected between the input pi n and 0 V.

They can also be connected to a brake switch or other switc h.
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 i s measured
o Count: Counts the number of pulses
o Phase Difference: Calc ulates the phase diff er enc e between t wo digital

inputs

o Beacon: For connection of a lap beacon

MoTeC Installation 23

Spee d Inputs

Speed Inputs are i dentical to Digit al Inputs except that they can al so be
configur ed to suit Variabl e Reluctanc e ( M agnetic) sensors, such as some
wheel speed sensors. Becaus e the amplit ude of t he si gnal 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 Input s can also be used with Hall Effect t y pe 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 specif ications see Input Char ac teristics.

Expanders

If additional sensors are requir ed, input expanders can be used, such as
MoTeC’s E816 and E888. S ensors can be connected to the ex pander inputs
and communic ate 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 f ound in Out put Charac teristics.

Expanders

If additional outputs are requi r ed, output expanders can be used, e.g. P DM.
Expander outputs can perform t he same t asks as the devi c e outputs and can
be driven by communication via either RS 232 or CAN. See

Configuring

24 Installation MoTeC

Communications

Communications are used to send and receive data from one device to
another. T her e ar e two communication prot oc ols: RS 232 and CAN. Generally
older devices use RS232 and newer devices use CAN.

CAN (Controller Area Network) Communications

This protoc ol enables communicati on between all devices connected t o the
same bus. The CAN bus allows for c ommunicating at high speeds. The C125
has two independent CAN c ommunications ports that can be connected to
other devi c es with a c om patible 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 m odules: E 888, PDM
o Displays: SDL3
o Beacon receiver: BR2

These devi c es comm unic ate at 1 Mbit/sec, so any other devic es connected
on the CAN bus must also communic ate at 1 Mbit/sec. If a devic e
communic ates at another speed, it should be wired to the other CAN bus, and
the speed of that CA N bus must be set t o matc h the speed of t he dev ic e.

RS232 Serial Communications

This is a one to one protoc ol, communicating f r om one device to one other
device. Typic al dev ic es communicati ng ov er 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 appropri ate communications protocol defined.

Configuration Sequence

The configuration is best setup in the following order:

1. Connections (I nput Pins & Communicati ons)

2. Calcul ations (Lap Time, Fuel Predi ction etc.)

3. Functions (Loggi ng, Display , Alarms, Auxiliary Outputs etc.)

This simplif ies the setup procedure by ensuring that the required c hannels are

• New – creat es a new confi gur ation based on a predefined template

• Open – selects an existing file

Right-clic k the configuration fil e to Rename, Delete, Send to a disk etc .

• Save – saves a newly creat ed configuration with a meaningful name

is often the easiest way to open an existing file.

Backups

Whenever a file is saved, the previous cont ent of the file is saved in the Save
Backups directory. The tot al num ber of fil es i s limit ed 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 Pres s ur e’.
This channel may then be used by another system , such as t he Dis play
System or Data Logging s y s tems.

The Displ ay Logger channel scheme allows com plete flexibility in channel
usage, as any available channel can be used by any other func tion, i.e. any
channel can be logged, displayed, used i n condi tions, used in alarms, used as
an input to the user defi nable tables, et c.

All system s within the Display Logger t hat generate values must f eed one of
the channels.

Pre-defined Channels

MoTeC has defined an ex tensive list of channel s.

General Purpose Channels

Since the use of all channel s cannot be pr edetermi ned, a number of general
purpose channels have been included for occasions when a suitable
predefined c hannel is not avail able.

MoTeC Configuration 31

These general purpose chan nels may be requi r ed when measuring an
uncommon v alue, or when a general pur pose function needs to gener ate a
special out put channel. For exam ple, a 3D t able m ay generate an output
channel to c ontrol a v alv e of som e sort , in which case a general purpose
channel may be used and named appropriately .

32 Configuration MoTeC

Channel Properties

Each channel has defined properti es, some of which may be modified by the
user. Predefining these properties makes the channels easy to use
throughout t he r est of the software.

• Properties that may be modified by the user

o Name

The channel nam es (and abbrev iations) may be c hanged if necessary.
However name c hanges should be limited t o name preferences rat her
than redefining the purpose of t he channel , except for the general
purpose channels whic h m ay be r enam ed to suit t he c urrent use.

o Abbreviation
o Units (e.g. degrees Celsius, degrees Fahrenhei t)

The unit s for a channel can be sel ec ted from a predefined list, for
example the Engine Temperature channel m ay hav e units of degrees
Celsius, Fahr enheit or Kelvin. Conversion between units is
automatically handl ed by the software.
Note: The uni ts are used for display purposes only. This means that
the unit s can be changed at any time without affecting the calibration of
the channel.

• Fixed propert ies

o Measurement type (e.g. Temperature)

Defining the measurement ty pe allows the channel s to be displayed i n
any unit suitable for that type, with automatic conver si on between the
units. F or example all temperatur e c hannels can be displayed in
degrees Celsius, Fahrenheit or Kelvin.

o Resolution

The resolution of all channels i s fix ed, f or example the resolution of the
Engine Tem per ature channel is fixed at 0.1 ° C.
Fixed channel r esol utions ensure that the unit conversion system
works properly and that channel com pari sons can be per formed
correctly.

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

MoTeC Configuration 33

Selecting Channels

There are two methods of sel ec ting channels, either the Category Method or
the Search Method.

Category Method

This method div ides al l the channels into c ategories and sub categories, so
that the list c an be nar r owed down to a sm all list of channels. For ex am ple,
the ‘Engine S ensors / Cooling’ category shows a list of channels associated
with the cooling system of the engine.

When selecting a c hannel from the complet e list of channels, it is usually
easiest to use the categor y sel ec tion method, for ex ampl e when assigning a
channel to an input pin.

To expand a category

• c lick on the plus sign (+) next to the category name.

34 Configuration MoTeC
Search Method

This method lists al l c hannels in alphabetical order and allows a channel to be
found eit her by ty ping the first few letters of any word i n the channel name, or
by scrolli ng through the list.

Note: The words m ay be ty ped out of or der so that ‘E ngine Oil Temp’ could
be found by typing "t em p eng oil" or "oil t eng" or "e o t”

This method is most useful when selecting a c hannel f rom t he av ailable
channels.

For example, if ‘Engine Temperatur e’ has been assigned to an input pin, it
can be easily located in the Search list, s inc e this lis t normally only
contains 50 to 100 items.

Functions

Dat a Logging (optional)

Data logging allows sensor readings and calculated values to be stored i n the
Display Logger' s memory for later anal y si s using t he i2 Data Analysi s
software.

To configure lo gg ing

• On the Functions menu, click Logging

• Select the r elev ant tabs to set up the logging param eters

Power

The Displ ay Logger power can be turned off at any time without losing the
logged data, bec ause i t uses FLASH memory that does not require an internal
battery to keep it alive.

Logging Memory

The C125 has opti onal 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 defi nable conditions.

For example logging might start when the vehicle exceeds 50 km/h, and stop
when the engine RPM i s bel ow 500 rpm f or 10 seconds.

The Displ ay Logger provides the normal l ogging type; this will conti nuousl y
log data to memor y whenever the Start Conditi on is tr ue 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 over write the oldest data, which ensures that the
most recent dat a is al ways available. Thi s i s ref er r ed to as cyclic logging.

For most appli c ations it is recommended that cyclic logging is used.

Logging Time

The maximum logging time is dependent on the logging memory size, the
number of item s l ogged and the rate at which they are logged. T he Dash
Manager soft ware wil l r epor t the total available logging time.

38 Configuration MoTeC
Loggin g Set up Fil es

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

Logging Rate

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

The rate at which t he v alues are logged must be fast enough to recor d all
variati ons i n the reading. If the value is l ogged too slowly, the readings can be
totall y meaningless. For ex am ple, suspension po si tion may need to be logged
at 200 times per second or more.

However, if a value is l ogged faster than necessary i t will not improve the
accuracy of the logged dat a. It will just reduce t he total logging time available.
For example, the engine temperature only needs to be logged at once per
second.

CAN Bus Bandwidth Limit

High logging r ates also increase the am ount of data that is being received
from the measurement devices, which increases the amount of data on the
CAN bus. This can lead t o exceeding the CAN bus bandwidth limit. See

CAN Bus Bandwidth Limi t.

Note: The Dash Manager sof tware will warn if the bandwidth is likely to be
exceeded.

Maxim um Lo gging Rate

The maximum logging r ate is limited to the update r ate of the particular
channel. This varies signific antly depending on t he source of the channel.
For example, some communications devic es may only update at 50 Hz .
Also some inter nal c alc ulations may be limited to 100 Hz.

Update Rate

Each input i s measured at a m aximum rate which is dependent on the
capabili ties 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 t hen an
optional anti-alias filter can be applied.

The anti-ali as filter is used to average out any v ari ations in the signal bet ween
logged v alues. This ensures that unrepresentative values are not logged.

MoTeC Configuration 39

The anti-ali as filter is implemented by averaging the channel values between
logging ev ents. For example, if a channel has an update r ate of 1000 Hz and
it is logged at 100 Hz then t he pr ec eding 10 samples will be averaged each
time it is logged.

The anti-ali as filter is normally turned on by default when a channel is added
to the loggi ng list, but may be turned off if requi r ed. F or normal pur pose s i t is
recomm ended that the anti-alias filter is left turned on.

Note: For som e channel s the anti-alias filt er c annot be turned on because the
averaging performed by the filt er would cause inc or r ec t values. This is the
case for on/ off channel s and channels where the bit values have a particular
meaning, for example error group c hannels.

Real Time Value (ADL2, SDL)

For channel s that com e from an A DL2 or an SDL, the logging anti-alias
filt er al so affects the real-time value of the channel. This is the value that
all other par ts of the system see, such as the various cal c ulations.

Note: The anti-alias filter is limited to 50 Hz for real time values even if the
channel is logged at a lower rat e. For example, a channel logged at 10 Hz
will be filt er ed and updated at 10 Hz in the logging and 50 Hz for the real
time value.

Note: Channels that are not logged are updat ed at 50 Hz.

Real Time Value (Fo r devi ces other than ADL2, SDL)

The real time value from other devices and from internal calc ulations is not
anti-aliased at the logging rat e, however the value can be anti-ali ased i n
the logging.

Phase Shift

The anti-ali as filter will cause a phase shift (tim e delay) of half the logging
rate. For example, a channel logged at 100 Hz is logged every 10
milli seconds, 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 sam e am ount, whic h

negates this effect when compari ng these channels.
This applies to all c hannels whether they are generated inter nally from a

calculation or whether they are gener ated externally from dev ices such as
a display devic e.

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 sen sors that will provide the required
information.

Track Map using GPS

Ensure GPS Latitude and GPS Longitude are logged.

Track Map using Sensors

The foll owing sensors are required and must be l ogged:

• Lateral G force (internal sensor)

• Wheel Speed

• Lap B eac on ( the ‘Beacon’ Channel m ust be logged)

• Optionally Longitudinal G for c e (inter nal sensor)

A Longitudinal G force sensor should be used if the vehicle has only
one wheel speed sensor. This allows the analysi s sof tware to eliminate
wheel loc k ups which is essential when creating or using a track map.

MoTeC Configuration 43
Bar 1 and Bar 2

The Bar 1 and Bar 2 facility pr ov ides the means to configure t wo bar ty pe
graphs. One coul d m ost lik ely be c onfigured to graphical ly represent the
current value of the Lap Gain/Loss Running channel as a Gain / Loss bar, the
other can be confi gur ed as any ot her useful indic ator such as a batt er y
voltage, f uel, temperature or pr essure gauge.

Two intermediate points can be set, see the bat tery voltage example below.
However, a gain/loss bar can only use the fir st intermediate point.

Example Bar 1 (gain / loss bar) and Bar 2 (bat t ery vol t age gauge)

These bars can be customised to suit a user's preferenc e. The properties for
these two exam ples are shown below.

In the battery v olts example, with the Change whole bar c olour option not
selected, the three specific c olour s wil l display in the relativ e secti on of t he bar
according to the channel value, as shown in the ex am ple.

If the Change whole bar colour option is select ed, the whole bar colour will be
red if the channel v alue is from 8 to 13, green from 13 to 15 and red from 15
to 16.

44 Configuration MoTeC

The bars can be customi sed to sui t a user's preference. For example:

• Setting t he scale and the time units.

• Customi se the labels at either end of the bar. In t he GAIN/ LOSS example

above, LOSS + 1 and GAIN -1 are used, where 1 is the scaling value.
Another l abel ex am ple c ould be LEFT and RIGHT.

• Invert c olour s.

• Specif y the negative to the left or right.

Dial or Bar Graph (depending on style chosen)

Example dial

Example sweep bar

Example linear bar

The dial or bar graph has a user def inable range and i s typically used as a
tacho, however it can be used to display any other v alue.

A fully programmable shift poi nt can be displ ay ed, which can also be gear
dependent.

MoTeC Configuration 45
Top Displays

The numeri c di spl ay s can be progr ammed to display any channel value.
The numeri c di spl ay s can show any channel value plus up to two over ri de

values. Ov er ri de v alues di spl ay eac h time their value is updated. This is
useful for v alues that are updated periodically. The override values are shown
for a programm able per iod of time. For example, a numeri c displ ay c ould
normally show the Running Lap Time (which is continuously updating) , then
be overwritt en by the Lap Time for 10 seconds each time the Lap Time is

MoTeC Configuration 49

Display Setup with Display Creator

When using Displ ay Cr eator, communications and channels need to be set
up. To autom ate t his, a DB C file is creat ed when the Dash Manager
configur ation is saved. This file c an then be imported into Di spl ay Creat or .

The Display Creator Channels and Display Cr eator Settings tabs are used to
set the defi nitions for creati on of t he DBC file. This file is then import ed into
Display Creator to automat e the communications and channels setup.

External Displays (Display Creator) with CAN

External display s created with Display Cr eator use CAN for messaging, the
following CAN v alues must be set:

• The CAN bus

• The address f ormat

• The base address, or select the default.

A warning will display if any of the CAN settings conflict with existing CAN
configurations.

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 conf iguration is saved.

The DBC file is im ported by Displ ay Cr eator to automate the setup of
communic ations and channels.

Note: Channels selected i n the Display Cr eator Setting tab (see below) m ust
also be selected in this list for them to be included in the DBC file.

Display Creator Settings Tab

This tab is used to define page display behaviour.
Note: The channels selected on this tab m ust also be included in the Display

Creator Channels list (see above) for them to be included in the DBC file for
import to Displ ay Cr eator.

Number of Pages

Specifi es the num ber of pages defined in the appli c able Display Creator
configuration.

Preserve Page

If ticked and t he dev ic e is power cycled, the last page that was displayed for
at least five second before the power cycl e oc c ur r ed will displ ay .

If not tick ed and the devic e is power cycled, the def ault page will display.

50 Configuration MoTeC

Page Channels

Specifi es the c hannels used to set page up, down and reset values.

Page up is the next page in numeric sequence, def ault channel is Display
Page Up Button.

Page down is the prev ious page in numeric sequence; default channel is
Display Page Down B utt on.

Page reset r eturns the display to the def ault page; default channel is Display
Page Reset Button.

Output Channels

This is used to select the output channel, which is the channel that c ontrols
the page display ed; default channel is Display P age.

Note: For page control to functi on, t his channel should be included in the
Display Creator Channels li st so that it is i ncl uded in the DBC file for import to
Display Creator.

For example, if t he output c hannel v alue is 3 (that is page 3 is displayed), it is
increased to 4 via the Display Page Up Button channel and decreased to 2 vi a
the Display Page Down Button channel.

Options Ta b

This tab is used to select whether a DB C file should be generated, and if so,
its filename.

If the DBC file is to be generat ed, specify a filename or select the default, The
default syntax is: [name of the configuration]-[display nam e]. dbc .

MoTeC Configuration 51

Alarms

Alarm Compa risons

The warning alarm limits are fully program m able and may include up to 6
comparisons to ensure that the alarm s are only ac tivated at the correct time.

For example, an engine temperatur e alarm may activate at 95 °C if the ground
speed has been above 50 km/ h for 30 seconds. The speed compari son
avoids the al arm showing duri ng a pit stop due to heat soak. Additionally
another comparison could be set at a hi gher tem per ature to cover all other
situations.

The comparison values can be automatically incremented or ( dec r em ented)
when an alarm occ ur s. For ex am ple the engine temperature alarm may be set

at 95 °C with and increment of 5 °C, so that the second tim e the alarm
activ ates at 100 °C. A limit may be set on the number of times the comparison

value is allowed to increment. An alarm may retur n to its original value aft er a
period of time, in case the alarm condition was temporary.

The alarm s can be dependent on the current display mode page (Warm-up,
Practice or Rac e).

Alarm Behaviour

Alarms are eit her :

• Active and unack nowledged ( alarm conditions are true).

• Inactive and unacknowledged (alar m c ondition was true but became

not true bef or e alarm was acknowledged).
These will c ontinue to display until ack nowledged.

• Active and ack nowledged ( alarm conditions are true but not
displayed).

• Inactive (conditions needed to make an alarm active are not met or
true).

The following behaviour applies:

• Active and inactive unacknowledged alarms remain displ ay ed until
they are acknowledged, eit her by t he Acknowledge B utt on or
automatically after a defined period of time. After ac k nowledgem ent,
and if the alarm is stil l ac tive, it may display again after the "do not
display message int erval" has el apsed.

Note: If it appears that an active unac k nowledged alarm cannot be
acknowledged (that is, it continues to display), it could be that the "Do
not display this message again until ... seconds have elapsed" i s set
to zero.

52 Configuration MoTeC

• If there i s more than one unack nowledged alarm, the alarm with the
highest pri or ity (that is, the al arm that is hi ghest on the alarm list) is
displayed.

• If there are a number of unack nowledged alarms, t hese will displ ay in
priorit y sequence as each hi gher pr iority al arm is acknowledged.

Alarm Status Panel

Additionally an Alarm Status panel m ay be di spl ay ed whic h shows the curr ent
state of up to 6 activ e acknowledged alarm s. The panel is off by default and
may be turned on or off using t he Al arm Ac k nowledge button when there are
no alarm messages displ ay ed. If displayed, it will be obscured while ther e is
an unacknowledged alarm.

Below are four examples of the Alarm St atus Panel .

Other Functions

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

Shift Light s – to configure the shif t point values for use with the Shift Lights.
Shift Light M odule – to configure the C125 10 stage shift lights as well as an

additional MoTeC's SLM-C or SLM.

MoTeC Operation 53

Operation

When operating the C125, any of the activ ities of the Online menu of the

CAN Bus Wiring Requirements

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

o If the CAN bus is less than 2 met r es (7 ft) l ong, a single termination

resistor m ay be used.

• The preferr ed c able for the trunk is 100R data cabl e.

• 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 73

C125 Displ ay L og ger to ECU wiring (RS232)

The following details the methods for c onnec ting the Data Logger to vari ous
MoTeC ECUs via RS232. In all cases thi s i s done using the serial data stream
generated by the Telemetry function of each ECU.

In the case of the M800, M880 and M4e t he Data Logger m ay be dir ec tly
wir ed to the ECU because these ECUs use RS232 interface levels. On the
M48, M4 (pre M4e) and the M8, a Comput er Int erface Module (CIM) or a PCI
cable is requir ed to convert the signal s to RS 232.

M4e

Note:

• Older M4 ECUs requi r e a diff er ent connec tion method

• The data to the Display Logger will be inter r upted while a PC is

connected.

M48, M4 (pre M4e) and M8

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

Using a CIM Module

Contact MoTeC f or the CIM m odule dr awing for full wiring detai ls.
Note:

• The data stream to t he Displ ay Logger will be interrupted whil e a P C is
connected.

frequently the data is sent from the devic e. Typically the update rat e from an
M4, M48, M8 or M800 ECU is about 20 tim es per second using RS232 and
about 50 times per second for the M800 and M84 using CAN.

CAN Bus Bandwidth Limit

The total av ailable CAN bandwidth on a singl e CA N bus is 1 Mbit/sec.
The bandwidth used by the t otal of all devices on a parti c ular CAN bus must

not exceed approximately 90% of this value (900000 bits/second)
If the tot al bandwidth requir ed exceeds this specific ation then some devices

should be connected t o the second CAN bus.
Note: Dash Manager will warn if the bandwidth is likely to be exceeded.

Comms Error Codes

The "Comms CAN x Diagnostic " and " Comms RS232 Diagnostic" c hannels
can be used to diagnose communications probl ems.

Multiple er r or s are shown by error c odes added together. F or example:
A RS232 error of 9 = parit y + overr un.

The error values have the following definitions:

RS232 Errors

Errors generated by RS 232 c ommunications.
1 PARITY

Parity bit incorrect. The comms parity setup is
wrong, or there i s el ectr ic al interferenc e c ausi ng
errors in the data.

2

FRAMING

Not seeing the stop bit. The baud rate or stop
bit setup is wrong or there is electri c al
interference causing errors i n the data.

4

NOISE

Glitch in t he data. El ectr ic al interferenc e is
causing glit c hes i n the signal. (the Display
Logger does not generate this error )

8

OVERRUN

A byte was received before the previous byt e
was read indicating that the proc essor was too
busy to read the message.

512

NO DATA

A valid message header was not found - either
there is a wiring f ault or comms is setup
incorrectly.

1024 CHECKSUM

A valid message header was found, but the
checksum was wrong. If seen i n c om bination
with other err or s ther e is el ec trical noise. If only
checksum err or s occur there m ay be a
software inc om patibilit y between the Display
Logger and the other dev ice.

2048 WRONG DATA Could not decode the protocol.

MoTeC Appendices 81
Gen eral CAN Errors

Errors generated by gener al CAN communi c ations.
2 FRAMING

8

OVERRUN

Receive or transmit overrun error . I n the
receive c ase a byt e was receiv ed before the
previous byte was read indicating that the
processor is too busy to r ead 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 devic e configur ation 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 comm s is
setup incorrec tly, (probl em could be at either
end), e.g. transmit and receive CAN IDs do
not match.
