  • Page 8: System Overview

    #61132 Ethernet to Autosport pins cable, 1.8 m System Overview The C185 offers extensive possibilities to integrate with ECUs, peripheral devices and accessories to form a complete solution that powers, controls, logs, monitors and communicates virtually any automotive parameter.

  • Page 9: Typical Devices Used With C185

    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.
  • Page 10 Note: The E888 / E816 inputs have lower resolution than the VIM/SVIM inputs and have slower update rates. Accessories 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.
  • Page 11 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.
  • Page 12 MoTeC 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.

    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.

  • Page 14: Connecting Devices

    • 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.
  • Page 15 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.

  • Page 16: Outputs

    MoTeC Installation 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.
  • Page 17 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.

  • Page 21: Configuration

    All changes to the C185 configuration are performed ‘Offline’, i.e. without the PC communicating with the C185. The changes are saved in the configuration file on the PC. The file must be sent to the C185 before the changes take effect. See Operation.

  • Page 22: Channels

    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.

  • Page 24: Channel Properties

    MoTeC Configuration 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.

  • Page 25: Selecting Channels

    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’...
  • Page 26 MoTeC 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"...

  • Page 27: Connections

    Configuring Outputs • On the Connections menu, click Devices • Select device (e.g. C185) and then click the Output Pins tab to list all outputs available for this product Note: Some outputs require 52 I/O Upgrade to make them available. See C185 Upgrades.

  • Page 28: Calculations

    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.

  • Page 29: Functions

    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.
  • Page 30 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.
  • Page 31 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 and it is logged at 100 Hz then the preceding 10 samples will be averaged each time it is logged.
  • Page 32 MoTeC Configuration 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) •...

    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.

  • Page 74: Pc Connection - Ip Address

    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.
  • Page 75 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.
  • Page 76 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)
  • Page 77 Appendices Network Switches and Cables The C185 must be connected to the network via a network switch.
