MoTeC Introduction 3 Compatibility • MoTeC ECUs: M4*, M48*, M8*, M400, M600, M800, M880, M1 • MoTeC Accessories: VIM, SVIM, E888, E816, SLM, PLM, LTC, BR2, PDM, GPS, VCS, Telemetry etc.
4 Introduction MoTeC 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.
MoTeC Introduction 5 E888/E816 The C185 supports two E888 or E816 Expanders allowing expansion 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.
6 Introduction MoTeC 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.
MoTeC Introduction 7 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 power to the various electrical systems in the vehicle.
8 Installation MoTeC 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.
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.
10 Installation MoTeC 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.
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.
12 Installation MoTeC CAN (Controller Area Network) Communications This protocol enables communication between all devices 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 each interface can be set independently.
MoTeC Installation 13 Connecting Devices Examples Device Connect via Remarks Sensors Inputs: The appropriate input type depends on the sensor type MoTeC supplies datasheets with wiring details for all sensors via the website External Buttons for: - Display mode - Display next line (and optional previous line) - Alarm acknowledge - Lap number reset - etc. Inputs: Switch input Alternatively Digital or Analogue Voltage inputs can be used Wire between C185 input and C185 0V.
14 Installation MoTeC Software Installation C185 Dash Manager Software C185 Dash Manager software is used for configuration, testing, retrieving the logged data, and for general management of the C185. C185 Dash Manager supports configuration of the following connected devices: VIM, SVIM, E888/E816, SLM. PC Requirements C185 Dash Manager runs under Windows XP or Vista operating systems.
MoTeC Installation 15 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 worksheets. 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.
16 Configuration MoTeC 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 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 configuration file on the PC. When starting C185 Dash Manager the menu items related to changing the configuration are unavailable.
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’.
18 Configuration MoTeC Channel Connection Example Sensors Analogue Inputs ECU Speed Inputs CAN Comms Data Logging System Logging Memory Display System LCD Display Alarm System RS232 Comms Telemetry Channels Auxiliary Outputs Gear Alarm Warning Light Engine Temperature Engine RPM Wheel Speed Rear Wheel Speed Front Oil Pressure Fuel Pressure Gear Detection Warning Light
MoTeC Configuration 19 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.
20 Configuration MoTeC 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.
MoTeC Configuration 21 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.
22 Configuration MoTeC Connections Configuring Inputs • On the Connections menu, click Devices • Select the device (e.g. C185) and then click the Input pins tab This will list all inputs available for this product Note: Some inputs require the 44 I/O Upgrade to make them available.
MoTeC Configuration 23 Comms Templates Communication templates are available for most connected MoTeC devices. When MoTeC releases new products, new communication templates will also be released. These will be incorporated in the latest software versions. See Updating C185 Dash Manager Software on how to update to a new software version to make the latest communication templates available. Calculations The C185 has special and user definable general purpose calculations available.
24 Configuration MoTeC 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.
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.
26 Configuration MoTeC 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 and it is logged at 100 Hz then the preceding 10 samples will be averaged each time it is logged.
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.
28 Configuration MoTeC Display Using Fixed Layouts The C185 display is a high contrast, high brightness colour LCD display. To configure fixed displays 1. On the Functions menu, click Display. 2. Select the relevant Display type 3. Select the required mode (RACE, PRACTICE, WARMUP) by selecting the relevant tab. 4. Select the required fixed display style by double-clicking on the fixed display style displayed down the left side of the Edit Display Style screen.
MoTeC Configuration 29 Display Modes (Pages) The display has three display modes or pages; 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.
30 Configuration MoTeC Bar 1 and Bar 2 The Bar 1 and Bar 2 facility provides the means to configure two bar type graphs. One could most likely be configured to graphically represent the current value of the Lap Gain/Loss Running channel as a Gain / Loss bar, the other can be configured as any other useful indicator such as a battery voltage, fuel, temperature or pressure gauge. Two intermediate points can be set, see the battery voltage example below.
MoTeC Configuration 31 The bars 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 GAIN/LOSS example above, LOSS +1 and GAIN -1 are used, where 1 is the scaling value. Another label example could be LEFT and RIGHT. • Invert colours. • Specify the negative to the left or right.
32 Configuration MoTeC Top Displays The numeric displays 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.
MoTeC Configuration 33 Bottom Display 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.
34 Configuration MoTeC Alarm Displays When an alarm is activated, a message is shown along the bottom of the display until it 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. Example active unacknowledged alarm See the Alarms section for details on behaviour and operation of alarms.
MoTeC Configuration 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.
36 Configuration MoTeC Display Setup with Display Creator 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 Display Creator to automate the communications and channels setup.
MoTeC Configuration 37 Page Channels Specifies the channels used to set page up, down and reset values. Page up is the next page in numeric sequence, default channel is Display Page Up Button. Page down is the previous page in numeric sequence; default channel is Display Page Down Button. Page reset returns the display to the default page; default channel is Display Page Reset Button.
38 Configuration MoTeC Alarms Alarm Comparisons 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.
MoTeC Configuration 39 • If there is more than one unacknowledged alarm, the alarm with the highest priority (that is, the alarm that is highest on the alarm list) is displayed. • If there are a number of unacknowledged alarms, these will display in priority sequence as each higher priority alarm is acknowledged. Alarm Status Panel Additionally an Alarm Status panel may be displayed which shows the current state of up to 6 active acknowledged alarms.
40 Operation MoTeC 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, click 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.
MoTeC Operation 41 Checking Operation Monitor Channels • On the Online menu, click Monitor Channels • To show any channel on an oscilloscope style screen, click Utilities and then Oscilloscope The currently active channels can be monitored to check the operation of all functions and measurements. Simulate • On the Online menu, click Simulate The Simulate feature allows most input channels to be manually changed so that the C185 operation can be checked under abnormal conditions, e.g.
42 Operation MoTeC 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 C185: • 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.

MoTeC Appendices 63 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 meter (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 meter (50 ft) • CAN devices (such as MoTeC Dash Loggers, ECUs etc) may be connected to the trunk with up to 500 mm (20 in) of twisted wire.
64 Appendices MoTeC 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.
MoTeC Appendices 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.

MoTeC Appendices 69 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 bus. Note: C185 Dash Manager will warn if the bandwidth is likely to be exceeded.
70 Appendices MoTeC 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.
MoTeC Appendices 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.
72 Appendices MoTeC 256 BAD CONFIG Configuration mismatch between C185 and device. Resend the configuration. 512 NO DATA VIMCOM packets have not been found. 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.
MoTeC Appendices 73 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.
74 Appendices MoTeC 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.
MoTeC Appendices 75 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.
76 Appendices MoTeC Network Switches and Cables The C185 must be connected to the network via a network switch.
