4 Introduction

Typical Devices Used With C185

ECUs

The C185 can be connected to most MoTeC ECUs and some other manufacturers' models either via CAN or RS232. This avoids duplication of sensors and allows the C185 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.

Sensors

The C185 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.

Expanders

VIM / SVIM

The VIM is a compact and versatile input expander module with 24 analogue inputs of various types including high speed, high resolution and differential types. The VIM also has two digital inputs with programmable trigger levels.

Several VIMs may be connected to the C185 providing more than 300 sensor inputs. The VIM supports many different types of sensors including unamplified thermocouples and strain gauges.

The Synchronous Versatile Input Module (SVIM) is a compact expander that works the C185 to facilitate the synchronised logging of high speed, high resolution inputs. Multiple SVIMs are synchronised so that every SVIM in the vehicle samples its high resolution AV inputs at the same instant in time.

SVIMs are versatile in nature and can be located close to sensors, reducing the weight and complexity of wiring. When used in multiples, up to 200 sensor inputs are available. The SVIM supports many different types of sensors, including unamplified thermocouples and strain gauges.

MoTeC Introduction 5

E888/E816

The C185 supports two E888 or E816 Expanders allowing expan sion of the number of inputs and outputs.

The E888 has 8 x 10 bit thermocouple inputs, 8 x 10 bit voltage inputs, 4 digital inputs, 2 switch inputs and 8 outputs.

The E816 has 16 x 10 bit voltage inputs, 4 digital inputs, 2 switch inputs and 8 outputs.

Note: The E888 / E816 inputs have lower resolution than the VIM/SVIM inputs and have slower update rates.

Accessories

BR2

A BR2 Beacon Receiver may be connected to the C185, which allows the C185 to calculate lap times for display and to provide lap information for the data logging analysis software.

SLM

The SLM Shift Light Module can be used for shift lights, warnings and other driver alerts.

It comprises 8 LEDs that can be programmed to display any colour.

GPS

The C185 supports many GPS (Global Positioning System) devices allowing the C185 to record speed, generate lap times and measure position information.

This information can be used in the i2 data analysis software to create track maps, and plot and compare driven lines.

Telemetry

The C185 supports transmission of data via a telemetry radio to a remote location such as a pit garage. This allows monitoring of the current vehicle condition, position on the track, lap times, fuel remaining, laps remaining etc.

The telemetry system provides three major functions:

1. Real time data that is transmitted continuously and can be shown on graphs, gauges and other displays.

2. End of lap data which shows summary information at the end of a lap such as lap time, maximum temperatures etc.

3. Telemetry analysis which exports the real time data to the i2 analysis software at the end of each lap or on demand which allows normal

6 Introduction

analysis of the data including maths calculations, while the vehicle is still on the track.

Other telemetry features include: warning alarms, position of multiple vehicles on a track map, broadcast data via DDE (Dynamic Data Exchange) or via IP (Internet Protocol).

Note: The Telemetry option is required for the basic functionality. The Remote Logging option is required in addition to the Telemetry option for the Telemetry Analysis function.

High Definition Video

MoTeC brings true high definition to motorsport with its new HD Video Capture System. The HD-VCS provides superior quality video and numerous features designed specifically for the racing environment.

Features include:

• Genuine High Definition with 1080p @ 30 frames per secon d

• Automatic Start/Stop, eliminating the possibility of drivers forgetting to

turn it on

• 12 V power direct from the vehicle - no batteries to recharge

• Live gauges

automatically recorded on the video

• Over 5 hours of recording at 1080p

• Records to removable storage up to 32 GB

• Video can be played directly from the card

• Automatic CAN Synchronisation with data in i2 (available late 2013)

• Compact, lightweight recording unit

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

The 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 Lambda sensor and transmit Lambda readings via the CAN bus.

MoTeC 7 Introduction Remote Displays

A remote display device may be connected to the C185 to allow display of any value that the C185 calculates, such as lap times and warning alarm messages.

The C185 supports D153, D175 displays which are connected via CAN.

PDMs

Power Distribution Modules are designed to replace conventional relays, fuses and circuit breakers by providing electronically switched po wer to the various electrical systems in the vehicle. This simplifies wiring and switch requirements, while increasing reliability.

Full diagnostic information, including output curre nts and error status can be transmitted via CAN to the C185.

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 C185. Contact your dealer for advice.

8 Installation

Installation

Mounting and Wiring

C185 has three threaded mounting posts. For further detail 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 a ngle of

approximately 20 degrees, However the C185 will give good contrast between 0 and 40 degrees. Display reflections should also be considered when determining the mounting angle.

20°

The C185 uses a 79 pin Autosport connector. See Connector and Pin List by Pin Number for full details.

Wiring Tips

• To ensure that the connector is sealed, plug unused holes with filler plugs. A heat shrink boot may also be used if desired.

• 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 use d.

• Be careful not to nick the wires as this may result in wire failure or poor

crimping.

• Some sensor connectors may not be available with 22# terminals, in which case doubling the wire over gives the equivalent of an 18# wire. T his is suitable for many of the common sensor terminals.

MoTeC Installation 9

• Use the correct crimping tool for all contacts to ensure a reliable connection.

• Power the C185 via a separate switch and a 5 ampere fuse, to ensure the PC can communicate with the C185 without the need to power the rest of the vehicle.

• The C185 ground must have a direct connection to the vehicle battery.

• C185 is connected to other devices via the CAN bus. Refer to CAN Bus

Wiring Requirements for details.

Connecting Devices

Inputs

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

• Switch Inputs

• Digital Inputs

• Wheel Speed Inputs

Note: Some inputs require a device upgrade to make them available

In addition to sensors connected to the inputs, the C185 has internal sensors available for battery voltage, 3-axis G force and device temperature.

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 o Signal conditioned 3 wire pressure sensors o Thermocouple amplifiers o Accelerometers

10 Installation

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.

Switch Inputs

Switch inputs are generally 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

Digital Inputs are identical to Switch Inputs except that they include the following additional 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 Beacon: For connection of a lap beacon

Speed Inputs

Speed Inputs are identical to Digital Inputs except that they can also be configured to suit Variable Reluctance (Magnetic) se nsors e.g. some wheel speed sensors. Because the amplitude of the signal from these

MoTeC Installation 11

sensors varies with speed of rotation, variable trigger levels are required, which must vary with the frequency of the input signal.

The Speed Inputs can also be used with Hall Effect type wheel speed sensors.

The Pulse Width measurement 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 e.g. E888, E816, VIM, SVIM. Sensors can be connected to the expander inputs and communicate via either RS232 or CAN. See Configuring Com munications.

Outputs

Auxiliary Outputs are used to control various vehicle functions e.g.

o Gear Change Lights o Warning Lights o Thermatic Fan o Gear Box Oil Pump

Note: Devices that consume more than the maximum current (e.g. motors) should be driven via a relay or PDM.

Output Specifications

Full specifications can be found in Output Characteristics.

Expanders

If additional outputs are required, output expanders can be used e.g.E888, 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 devic e to another. There are two communication protocols; RS232 an d CAN. Generally older devices use RS232 and newer devices use CAN.

12 Installation CAN (Controller Area Network) Communications

This protocol enables communication between all de vices connected to the same bus. The CAN bus allows communicating at high speeds. The C185 has two independent CAN communications ports that can be connected to other devices with a compatible CAN port. The bus speed for ea ch interface can be set independently.

Typical devices communicating over CAN:

o 'Hundred series' ECU: M400, M600, M800, M880 o Shift Light Module: SLM o Lambda meters: LTC, PLM o Expanders and input modules: E888/E816, VIM o Displays: SDL 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 M4, M48 ECUs o Radio telemetry device o Global positioning system: GPS

Note: The C185 can communicate with devices for which it has the appropriate communications protocol defined. For other devices, users can define their own custom communication settings.

There are two levels of analysis functionality available; i2 Pro and i2 Standard.

MoTeC 15 Installation

i2 Standard is included, while i2 Pro requires the optional Pro Analysis

upgrade. See C185 Upgrades. i2 Pro provides advanced mathematics, multiple overlay laps, and unlimited

components, workbooks and worksheet s.

Telemetry Monitor Software

The Telemetry Monitor software is used to monitor the optional telemetry link and allows viewing of live data in various graphical formats such as charts, bar graphs and dial gauges. It can also show the vehicle's current track position on a track map and compare the current vehicle data to reference data.

Telemetry Monitor software requires the optional Telemetry upgrade. See C185 Upgrades.

Connecting the C185 to a PC

The C185 connects to the Ethernet port on the PC. This requires a connector for the standard Ethernet cable in the loom.

The C185 loom #61213 incorporates this connector. Alternatively the connector can be wired into an existing loom using the unterminated Ethernet cable (#61131) or the Ethernet to Autosport pins cable (#61132).

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

PC Communications Setup

To enable PC communications a connection must be setup in the C185 Da sh Manager to match the C185 serial number.

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

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

type

• Enter the C185 serial number

If the PC needs to communicate with more than one C185, repeat the steps. Only one connection can be active at a time. To switch to a different C185

select the appropriate connection and click Make Act i ve.

Network Connection

Optionally, the C185 can be connected to a network. This allows for any PC on the network to communicate with the C185.

For more information on IP addresses see PC Connection - IP Address.

16 Configuration

Configuration

All aspects of the C185 can be configured including, which sensor is connected to which input, the calibration of each sensor, what to display an d 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 configuration file on the PC. When starting C185 Dash Manager the menu items related to cha nging 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 C185 configuration are performed ‘Offline’, i.e. without the PC communicating with the C185. The changes are saved in the config uration file on the PC. The file must be sent to the C185 before the changes take effect. See Operation.

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 File

From the File menu the following option 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 after a new configuration has been defined, it should be saved with a meaningful name.

• Save as can be used to create a copy of an existing configuration file by giving it a new name.

• Edit Details allows for entering event, venue and vehicle details to be stored with the configuration file.

• Check Channels verifies that all channels are co rrectly generated.

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

• Exit exits the program.

MoTeC Configuration 17

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 C185. For example an input pin may feed a channel called ‘Fuel Pressure’. This channel may then be used by another system, such as the Display System or Data Logging systems.

The C185 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 C185 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 predetermine d, a number of general purpose channels have been included for occa sions when a suitable predefined channel is not available.

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.

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

20 Configuration

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.

Tip: To expand a category click on the plus sign (+) next to the category name.

MoTeC 21 Configuration 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”

his method is most useful when selecting a channel from the available

only

T 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 contains 50 to 100 items.

24 Configuration

Functions

Data Logging

Data logging allows sensor readings and calculated values to be stored in the C185 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

Refer to C185 Dash Manager online help for additional information.

Power

The C185 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 C185 comes with 250 MB memory as standard. The Data Logging upgrade will increase this to 500 MB. See C185 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.

C185 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 C185 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 configuration software will report the total available logging time.

MoTeC Configuration 25 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 C185 can store values at up to 1000 times per second.

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 C185 Manager 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 VIM inputs update at 5000 Hz, whereas some communications devices may only update at 50 Hz. Also so me 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. For example the VIM has some inputs that update at 500 Hz and others that update as fast as 5000 Hz. 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.

26 Configuration

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.

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 a nd 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 value s have a particular meaning, for example error group channels.

Real Time Value (VIM/SVIM, ADL2, SDL)

For channels that come from a VIM, SVIM 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 VIM, SVIM, 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 VIM or a display device.

MoTeC Configuration 27 Track Map Sensor Requirements

In order for the i2 Data Analysis software to plot a track map 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.

28 Configuration

Display

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

from predefined styles.

To configure the display

1. On the Functions menu, click Display

2. Select the required mode (Race, Practice, Warmup) by selecting the relevant tab.

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:

a. Select the display. b. Select the Change button. Alternatively, double click on the relevant display.

29 MoTeC Configuration

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.

Warm-up 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 an d 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.

30 Configuration

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.

31 MoTeC Configuration

Top Displays

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

The numeric displays can show any channel value plus up to two overri de 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 coul d 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.

32 Configuration Centre Display

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

Bottom Display

33 MoTeC Configuration

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 chann el 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.

34 Configuration

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 purpos es, for example the engine temperature is measured to 0.1 °C but is better displayed with no decimal places.

Other Functions

The C185 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.

Operation

To perform any of the activities in the Online menu, the PC needs to communicate to the C185.

Note: All other menu items perform offline activities.

Retrieving the Logged Data

• On the Online menu, cli ck Get Logged Data

A personal computer is used to unload the logged data from the C185. The logged data is then stored on the computer 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 hard disk. In this case the C185 logging memory is not cleared and logging will continue as normal at the end of the existing data. Next time the logged data is unloaded both the new data and the previously partly unloaded data will be retrieved.

Sending and Retrieving Configuration Files

• On the Online menu, cli ck Send Configuration to send the currently open configuration file

When a configuration file is sent to the C185 the existing C185 data is retrieved and stored in the From Dash Backups directory to use in case the data in the C185 needs to be restored. The maximum number of files is 10.

• On the Online menu, cli ck Get Configuration to retrieve the current configuration file

This is normally not necessary unless the original file is not available on the PC.

C185 to ECU wiring (RS232)

The following details the methods for connecting the C185 to the 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 C185 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.

M800 / M880

Note:

• The data to the C185 will be interrupted while a PC is connected (DOS

software only)

• The 9 pin connector is not used if using the Windows Calibration software.

• Data may be sent to the C185 via the CAN bus as an alternative to the

serial connection.

M4e

Note:

• Older M4 ECUs require a different connection method

• The data to the C185 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.

MoTeC Appendices 61

Using a CIM Module

Refer to the CIM module drawing for full wiring details. Note: The data to the C185 will be interrupted while a PC is connected.

CAN Bus Bandwidth Limit

The total available CAN bandwidth available on a single CAN bus is 1 Mbit/sec.

The bandwidth used by the total of all devices on a particular CAN bus must not exceed approximately 90% of this value (900000 bits/second)

If the total bandwidth required exceeds this specification then some devices should be connected to the second CAN bu s.

Note: C185 Dash Manager will warn if the bandwidth is likely to be exceeded.

VIM

Approximate Bandwidth = Total Measurement Rate (samples/sec) x 30 (bits per sample)

Note: The Measurement Rate for each input is equal to the logging rate for that input or 50 Hz, whichever is higher.

Example Calculation

4 channels at 2000 Hz 20 channels at 500 Hz 40 channels at 20 Hz (Occupies 50 Hz)

Calculation:

Total Measurement Rate = 4 x 2000 + 20 x 500 + 40 x 50 = 20000 (samples/sec)

Approximate Bandwidth = 20000 x 30 = 600000 (bits/sec)

E888/E816

Device on first CAN Address

Bandwidth = 145000 (bits/sec)

Device on second CAN Address

Bandwidth = 55000 (bits/sec)

Comms Error Codes

The "Comms CAN x Diagnostic" and "Comms RS232 Diagnostic" channels seen 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. (C185 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 C185 and the other device.

2048 WRONG DATA Could not decode the protocol.

General CAN Errors

Errors generated by general CAN communications. 2 FRAMING Only generated when used with an

E888/E816 expander. Inconsistent message length.

MoTeC Appendices 67

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 (eg

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 suspended when this error occurs. Check wiring, termination resistors and the CAN baud rate. Also check that CAN HI and CAN LO are correct (not swapped).

16384 CAN TRANSMIT CAN bus transmit warning

"VIMCOM" Errors

Errors generated by "VIMCOM" devices (VIM, ADL2, SDL). Note: VIM COM devices are connected via CAN.

C185 Errors

These errors are generated by the C185 communications system.

2 FRAMING Incorrect number of samples received.

68 Appendices

256 BAD CONFIG Configuration mismatch between C185

and device. Resend the configuration.

512 NO DATA VIMCOM packets have not been foun d.

Either there is a wiring fault or C185

Connections is setup incorrectly. 2048 WRONG DATA VIMCOM packet has bad length. 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

suspended when this error occurs.

Check wiring, termination resistors and

the CAN baud rate. Also check that CAN

HI and CAN LO are correct (not

swapped).

VIMCOM Device Errors.

These error codes are sent once by the VIMCOM device on resumi ng data transmission and therefore indicate why data was previously not being transmitted.

4097 STARTUP Device has restarted (normally due to

power up) Data is not sent until sync is

achieved. 4098 HALT Data not sent due to deliberate halt. For

example configuration or firmware being

sent. 4099 OVERRUN Data not sent due to transmit buffer

overrun (possibly due to CAN bus too

busy) 4100 SYNC TIMEOUT Data not sent due to C185 sync

message timeout (sync not received

from C185) 4101 CAN ERROR Data not sent due to error on CAN bus 4102 SYNC

EXCEEDED

Data not sent due to excessive sync

error (synchronisation too far out)

PC Connection - IP Address

Basic Direct Connection (Automatic IP Address)

The simplest way to connect the C185 to a PC is directly to an Ethernet port on the PC and using the default network settings (automatically obtain an IP address)

This method can take up to 60 seconds to connect on Windows XP. On Windows Vista it takes approximately 8 seconds. This delay will occur every time the Ethernet cable is connected to the C185 or the C185 is power cycled.

The advantage of this method is that the PC can be connected to a network when it is not connected to the C185 without having to change any settings on the PC (assuming the network is configured to obtain an IP address automatically)

When the C185 is connected to the PC, a network conne ction icon will appear in the Windows taskbar tray. To check that connection is in progress, place the cursor over this icon. It will show “Acquiring Network Address”. Once the connection is established the message will show "Limited or No Connectivity". This is normal when using this method and means tha t Windows has automatically assigned an IP Address to the PC.

To check if the PC is configured to obtain an IP address automatically:

1. Click Start | Settings | Control Panel

2. Double click on Network Connections

3. Double click on the connection that is to be used to connect to the C185, usually this is called Local Area Connection

4. Click Properties

5. Select Internet Protocol (TCP/IP) from the list

6. Click Properties

7. Ensure that Obtain an IP address automatically is selected

70 Appendices

Fast Direct Connection (Fixed IP Address)

If the Basic Direct Connection method takes too long to connect, a more advanced setup can be used to reduce connection times to around 3 seconds.

Notes:

• Please be aware that changing the PC's network settings can make connections to other devices on the network stop working.

• Only change the PC network settings if the PC does not need to be connected to a network or to a device such as a cable or ADSL modem via the same Ethernet port.

• If the PC has a second Ethernet port that is not used to connect to a network then this can be used without affecting the network.

• On some PCs an unused Ethernet port may be available if the PC always connects to the network via a wireless connection.

MoTeC Appendices 71

To configure the PC with a fixed IP address:

1. Click Start | Settings | Control Panel

2. Double click on Network Connections

3. Double click on the connection that is used to connect to the C185, usually Local Area Connection

4. Click Properties

5. Select Internet Protocol (TCP/IP) from the list

6. Click Properties

7. Select Use the following IP address

8. Enter the IP address and Subnet mask shown below.

Network Connection

The C185 can also be connected to a network rather than directly to a single PC. This allows any PC on the network to communicate with the C185.

The connection time to the C185 will be less than 3 seconds (if the C185 is already powered and running)

Note: The PC network settings should not be changed.

72 Appendices Network Switches and Cables

The C185 must be connected to the network via a network switch. All MoTeC's PC connection cables (see PC Connection) are Ethernet

crossover cables, that allow direct connection to a PC and are compatible with network switches that support auto cable sensing (sometimes called “AutoMDI/MDI-X” or “Universal Cable Recognition”)

If the network switch does not support crossover cables MoTeC recommends upgrading the network switch rather than having two types of cables, which may cause confusion.
