6 Introduction MoTeC
Introduction
C125 - Club Display Logger
The C125 is a sophisticated display and powerful control device combined in
one lightweight unit. With the addition of a Data Logging upgrade it becomes
a fully programmable data logger with 120 MB memory (see Display Logger
Upgrades). The screen layout is fully configurable to display a multitude of
data channels, warning alarms, lap times, fuel calculations, minimum corner
speeds, maximum straight speeds and more. The C125 performs
calculations, acquiring data from other devices such as an ECU, another
Display Logger and input expander modules, which enable it to log a
multitude of inputs.
Features
All MoTeC Display Loggers come with a range of features as standard and
several options available as upgrades to customise and grow the system.
These additional features are activated through a simple password system,
and can be purchased at any time when you need them.
See Display Logger Upgrades.

System Overview
The Display Logger 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.
Typical devices used with the Display Logger
ECUs
The C125 Display Logger can be connected to all MoTeC engine
management systems and some other manufacturers' ECUs either via CAN,
RS232 or OBD-II. This avoids duplication of sensors and allows the Display
Logger 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, but is less from OBD-II.

MoTeC Introduction 9
Sensors
The optional Display Logger 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.
*To use these inputs, you will need to add the #29600 C125 I/O enable.
Expanders
E888/E816
The C125 fully supports two E888 or E816 Expanders allowing expansion
of the number of inputs and outputs
Accessories
BR2
A BR2 Beacon Receiver may be connected to the C125, which allows the
Display Logger to calculate lap times for display and to provide lap
information for the data analysis software.
SLM-C
The SLM-C Club Shift Light Module can be used for shift lights, warning
lights and other driver alerts.
The SLM-C includes 8 coloured LEDs that can be programmed to display
in a pre-defined pattern.
GPS
The C125 Display Logger supports many GPS (Global Positioning
System) devices allowing it to record speed and position information as
well as providing lap timing.
This information can be used in the i2 data analysis software to create
track maps, and plot and compare driven lines.
A 10 Hz GPS is supplied as part of the C125 Race Kits.
