Terminology
In order to assist in the installation and usage of the IQ3, the following provides an outline of
the most commonly used words that will be encountered in this manual.
Analog: Data created by the reading of a voltage change sent from a sensor
Calibrate: The process of assigning values to sensor voltage output, in order to graph and
analyze the sensor data.
Canbus: The specific name of the technology utilized to create the Vnet sensor system
Channel: The input from one sensor, as defined by the data logger.
Data Logger: See Data Recorder
Data Recorder: The vehicle mounted hardware device that collects and stores data transmitted
from the sensors
Digital: A sensor or signal that has only two values, off or on such as the measuring of ignition
pulses to calculate Engine RPM
Download: The process of transferring data saved on the data logger memory card to the user’s
PC using the DataLink software, in order to graph and analyze data. Memory card data must be
downloaded through the DataLink software and cannot be open directly from the memory card.
Filter: The process of smoothing the visual appearance of a graphed data channel.
Graph: A visual representation of sensor data, compared to time or distance
HZ: Number of times per second. Used to define logging or sample rate. Example: 4Hz
represents data that is saved 4 times (every .250) per second.
KB: Abbreviation for kilobyte, which represents one thousand bytes of information.
Logger: See Data Recorder
Logging Rate: The number of times per second, which the data logger records incoming data
from a sensor and is defined as Hertz, or Hz. Each sensors logging rate may be define by the
user.
Math Channel: A data channel created from the input of an actual sensor which is then used in a
mathematical formula to create a channel available for graphical analysis
MB: Abbreviation for megabyte, which represents one million bytes of information.
Overlay: The ability to graph multiple data channels, all at the same time.
Runfile: The file created when a run is transferred from the data logger memory card to the
user’s PC. Configuration File
Sample Rate: See Logging Rate
microSD Memory Card: Micro Secure Digital compact flash memory card
Sensor: A device that converts a physical property, such as pressure into a voltage signal
Smooth: See Filter
Start Logging Channel: The channel that is used to start the logging process
Trace: This term is another method used to describe Graph
Transducer: See Sensor
Vnet Channel: Any sensor that is connected to the Vnet port of the data logger
Vnet: Racepak exclusive that allows multiple sensors ( analog or digital) to transmit their data
over a single cable, back to the data logger.
