MoTeC Introduction 1
Introduction
The C185 comes standard as a combined full colour display, powerful control
device and fully programmable data logger with 250 MB memory (500
optional). The anti-reflective, high contrast display is clear and vibrant in direct
sunlight. Displayed channels and labels are configurable on supplied layouts;
software for fully configurable custom layouts available early 2014. The C185
acquires data from devices such as an ECU and displays data channels,
warning alarms, lap times, fuel calculations, maths functions and much more.
Features
The C185 comes with a range of features as standard and several options
available as upgrades to customise and grow your system. These additional
features are activated through a simple password acquired from MoTeC, at
any time when you need it. See C185 Upgrades

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 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.
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
