RaceCaptureTrack MK4

Quick Start Guide

Overview

RaceCapture/Track MK4 is our latest generation motorsports telemetry system

Connecting the Hardware

Mounting

To ensure optimal performance, mount the RaceCapture system on a flat, level surface within the vehicle, with the connectors oriented toward the front. This orientation aligns with the factory calibration of the internal accelerometer and gyroscope.

• Mount the unit in a concealed, protected area of the vehicle, away from direct heat sources and moisture.
• Use hook-and-loop (Velcro) fasteners or other suitable mounting methods to secure the unit in place while allowing for easy removal if needed.

Note: If it is necessary to install the unit in an alternative orientation (e.g., vertical, on-edge, or upside down), ensure it is rotated in clean 90-degree increments relative to the vehicle’s primary axes. Avoid mounting the device at an arbitrary angle, as this can affect sensor accuracy. For non-standard orientations, remap the accelerometer and gyroscope axes in the Setup menu to reflect the installed position.

Connectors

The RaceCapture/Track MK4 is equipped with the following connectors located on the rear panel of the module:

• M8 6-Pin Female Connector (CAN1 / CAN2 / Power)
• M8 4-Pin Female Connector (CAN1 / Power)
• RP-SMA Antenna Connector (L5_GNSS, LTE)

Positioning the Antenna

Secure the antenna to the RP-SMA connector on the RaceCapture/Track MK4 module. Tighten the connector to 5 - 6 in-lbs, slightly beyond finger-tight, to prevent it from vibrating loose during vehicle operation.

Caution: Do not overtighten the connector, as this may damage the SMA threads or the internal connection.

• Mount the antenna on the roof of the vehicle using the supplied magnetic base.
• Maintain a minimum separation of 3 feet (1 meter) from other transmitting antennas (e.g., cellular, FM/AM radio) to reduce signal interference.
• You can also place it on the dashboard, with an unobstructed view of the sky or on the rear parcel shelf, under the back window.

Note: Non-roof mounting may reduce GPS signal strength and tracking accuracy compared to optimal placement.

Powering up the Module

The RaceCapture/Track MK4 can be powered using the following methods: USB Power (USB Type-C) You may power the device via the USB Type-C port using any of the following sources:

• A computer USB port
• A USB car charger
• A USB battery pack

This method is ideal for quick setup, bench testing, or configuration. Vehicle Power via OBD-II (CAN1 / Power) Alternatively, you can power the module using the vehicle’s OBD-II port by connecting through an OBD-II to M8 4-Pin Female Connector.

Note: Ensure that the chosen power source provides a stable 12V supply as required by the device for accurate sensor feedback.
