Installation MoTeC o Signal conditioned three-wire pressure sensors o Thermocouple amplifiers o Accelerometers These inputs can also be used to measure two-wire variable resistance sensors if an external pull-up resistor is connected from the input to the 5 V sensor supply. Additionally, on/off switch signals may be connected, which may also require an external pull-up resistor.
MoTeC Installation Speed Inputs Speed Inputs are identical to Digital Inputs except that they can also be configured to suit Variable Reluctance (Magnetic) sensors, such as some wheel speed sensors. Because the amplitude of the signal from these sensors changes with speed of rotation, variable trigger levels are required, which must vary with the frequency of the input signal.
CAN (Controller Area Network) Communications This protocol enables communication between all devices connected to the same bus. The CAN bus allows for communicating at high speeds. The C125 has two independent CAN communications ports that can be connected to other devices with a compatible CAN port. The bus speed for each interface can be set independently.

Installation MoTeC If the Device is 'discovered' without the anti-virus software, you can turn it back on and put in appropriate exceptions to allow the Display Logger Manager to communicate with the device. Only one connection can be active at a time. To switch to a different Display Logger, click Make Active.
MoTeC Configuration Configuration All aspects of the Display Logger can be configured, including; which sensor is connected to which input, the calibration of each sensor, what to display and where to display it, what to log and how fast to log it, tacho range, warning alarms, multi stage shift lights etc.
Configuration MoTeC • Edit Details – allows for entering event, venue and vehicle details to be stored with the configuration file • Check Channels – verifies that all channels are correctly generated • Edit Configuration Comments – allows for other comments to be stored with the configuration file •...
Page 32
MoTeC Configuration 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.
Configuration MoTeC Channel Properties Each channel has defined properties, some of which may be modified by the user. Predefining these properties makes the channels easy to use throughout the rest of the software. • Properties that may be modified by the user o Name The channel names (and abbreviations) may be changed if necessary.
MoTeC 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 35
Configuration MoTeC Search Method This method lists all channels in alphabetical order and allows a channel to be found either by typing the first few letters of any word in the channel name, or by scrolling through the list. Note: The words may be typed out of order so that ‘Engine Oil Temp’ could be found by typing "temp eng oil"...

Configuration MoTeC Updating C125 Dash Manager Software on how to update to a new software version to make the latest communication templates available. Calculations The Display Logger has special and user definable general purpose calculations available. They are set up from the Calculations menu.
The Display Logger power can be turned off at any time without losing the logged data, because it uses FLASH memory that does not require an internal battery to keep it alive. Logging Memory The C125 has optional Data Logging upgrades providing 120 MB of logging memory. See Display Logger Upgrades.
Page 39
Configuration MoTeC Logging Setup Files The logging list can be saved and loaded from a file. This allows multiple logging setups to be used. Logging Rate The logging rate sets how often each channel is logged and can be set individually for each channel.
Page 40
MoTeC Configuration 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.

Configuration MoTeC Track Map For the i2 Data Analysis software to plot a track map, either a GPS should be connected or a number of separate sensors that will provide the required information. Track Map using GPS Ensure GPS Latitude and GPS Longitude are logged. Track Map using Sensors The following sensors are required and must be logged: •...
MoTeC Configuration Display Using Fixed Layouts The C125 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.
Page 43
Configuration MoTeC 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.
Page 44
MoTeC Configuration 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.
Page 45
Configuration MoTeC 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.
Page 46
MoTeC Configuration 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.
Page 47
Configuration MoTeC 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.
Page 48
MoTeC Configuration 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.
Page 49
Configuration MoTeC 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.
MoTeC Configuration 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.
Page 51
Configuration MoTeC 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.
MoTeC Configuration 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.
