Recommendations

Use the short 0.25 m cable where minimal distance is needed to avoid cable clutter and potential signal degradation. Verify and, if necessary, install manufacturer drivers on older operating systems to ensure reliable communication. Avoid exposing the connectors to moisture and mechanical strain during operation.
