Motec Systems C185 - Connecting Devices; Inputs

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.

Inputs
Input Types
A range of sensors is available to suit different types of measurement, e.g.
temperatures, pressures, speed. Each type of measurement generates a
different electrical signal that requires a suitable input type.
Each sensor needs to be connected to the type of input designed to suit that
type of sensor.
MoTeC devices have the following input types available:
• Analogue Voltage Inputs
• Analogue Temperature Inputs
• Switch Inputs
• Digital Inputs
• Wheel Speed Inputs
Note: Some inputs require a device upgrade to make them available
In addition to sensors connected to the inputs, the C185 has internal sensors
available for battery voltage, 3-axis G force and device temperature.
Analogue Voltage Inputs
Analogue Voltage inputs are normally used to measure the signals from
analogue voltage type sensors, i.e. sensors with variable voltage outputs,
such as:
o Rotary or linear potentiometers
o Signal conditioned 3 wire pressure sensors
o Thermocouple amplifiers
o Accelerometers
