GPS08 Module Setup Guide
AiM GPS08 Module Setup Guide
This guide explains the compatibility checks and setup sequence for an external AiM GPS08 on a supported system. It is not an instruction to fit GPS08 to every MyChron. Standard MyChron5, MyChron5S and MyChron6 models have internal satellite receivers.
Check the exact device before buying or connecting GPS08
| System | Receiver guidance |
|---|---|
| Original MyChron5 / MyChron5 2T | Internal 10 Hz GPS. GPS08 is not a routine requirement. |
| MyChron5S / MyChron5S 2T | Internal 25 Hz GPS. Do not apply original MyChron5 receiver specifications to the 5S. |
| MyChron6 / MyChron6 2T | Built-in 25 Hz GNSS. Do not purchase GPS08 as a standard installation or upgrade requirement. |
| Other AiM systems, including legacy and specialist configurations | Confirm the exact master device, receiver version, cable, firmware and connection against official documentation. AiM's MX 1.2/1.3 Strada manual documents GPS08 connections; this does not establish compatibility with every MX, EVO, SmartyCam or MyChron. |
This guide does not establish GPS08 compatibility for specialist MyChron5 660 or any other unlisted configuration. Ask Harris Race Radios™ to check the exact equipment before ordering or connecting a module.
What an external receiver contributes on a compatible system
Supported systems can use satellite data for position, speed, lap timing and track mapping. The functions available depend on the host device, receiver, configuration and track database. Sampling frequency alone does not establish positioning accuracy, and an external receiver is not automatically more accurate than the internal receiver in another device.
What you need
- A master device explicitly documented as compatible with the exact GPS08.
- The correct receiver, cable and any specified adaptor or network connection.
- The exact host-device and receiver installation instructions.
- Mounting and cable-securing materials suitable for the documented installation.
1. Choose the mounting location
Follow the receiver's documented orientation and mounting requirements, providing suitable sky visibility. Check surrounding bodywork, metalwork, heat, moving parts and ignition wiring. A kart nassau-panel mounting position must not be prescribed for every vehicle or host system.
2. Mount the receiver and secure its cable
- Confirm the exact receiver's installation procedure before attaching it.
- Prepare the mounting surface and use the specified fixing method and orientation.
- Secure wiring against abrasion, vibration, heat and moving parts without straining connectors.
- Check that the installation does not obstruct controls or compromise driver clearance.
3. Connect only to the documented interface
Use the wiring diagram for the exact master device and receiver. Do not assume that a matching-looking plug or a port labelled EXP proves compatibility. The former instruction to plug GPS08 into a MyChron EXP port is not a general MyChron5/6 installation procedure. Do not force connectors or substitute an unverified cable.
4. Confirm reception using the host-device instructions
Use the documented satellite-status display or diagnostic information for the actual device. The former red, green and flashing-green indicator table was not verified as a universal GPS08 status scheme and must not be relied on. No universal 5–15-second lock time is specified here; reception conditions and system state vary.
5. Verify track data and timing references
AiM's GPS08 documentation describes lap timing using the track list loaded to a compatible system. Check that the intended circuit and layout are present and that start/finish and split information are correct. Do not assume every listed NZ or Australian circuit or layout is included or automatically selected.
Where supported, use the documented Race Studio track-management workflow. For software guidance, see the Race Studio 3 Knowledge Hub. Harris Race Radios™ can help investigate missing or incorrect NZ/AU track information.
6. Test the supported installation
- Check mounting, wiring, connector security and the host-device configuration.
- Establish reception outdoors and confirm the device's documented status information.
- Confirm the selected circuit and timing reference before a safe controlled test.
- Review the recorded position, speed and lap data for plausibility before relying on comparisons.
7. Troubleshooting
- No reception: check documented compatibility, connection, power and reception conditions before relocating or replacing equipment.
- Intermittent data: inspect wiring, mounting and interference sources using the exact system's guidance.
- Wrong track or laps: check the circuit layout and timing references, not just receiver position.
- Persistent fault: record the receiver and master-device models, firmware and symptoms and contact Harris Race Radios™.
