SX-LINK Global Remote Diagnostic Bridge

What Is SX-LINK?

SX-LINK is SX-Tool's remote diagnostic bridge: a secure port-forwarding service that connects a technician's JET Pro or JET Master software to a customer's vehicle anywhere in the world. Once both sides are online, SX-Tool's servers handle routing, authentication and session management, delivering a low-latency link that feels like being plugged into the car.

How SX-LINK Works

SX-LINK creates an encrypted point-to-point tunnel between the technician's SX-Tool hardware and the end user's connected vehicle over ENET or USB interfaces. There is no firewall configuration or VPN to maintain — both parties connect, and the platform manages the session automatically for diagnostics, coding and flashing.

• JET Pro and JET Master — full remote control of the same diagnostic interface the customer-side technician would use locally
• JET LS Locksmith — remote JLR key programming and immobiliser services, covered in our remote key programming guide
• JLR ENET, SX-Tool DoIP and genuine DoIP VCI — secure remote communication for Pathfinder- and DoIP-era vehicles; background in JLR DoIP diagnostics explained

Professional Applications

SX-LINK turns a local workshop into a global service provider: engineers in different countries share diagnostic sessions, dealers support partner workshops remotely, locksmiths perform JLR key coding across regions, and trainers run live sessions — all without travel. Read the full breakdown in SX-LINK remote JLR diagnostics.

• Multi-workshop collaboration — share sessions between engineers in different countries
• Dealer network support — remote assistance for franchise or partner workshops worldwide
• Locksmith operations — secure remote JLR key programming via JET LS
• Training and demonstration — live diagnostic sessions for education, tied into our SX-Tool training programs
• Emergency technical assistance — professional support without physical travel delay

Security and Encryption

Every SX-LINK session is routed through SX-Tool's encrypted global network with real-time authentication and data-integrity monitoring. Operations occur within protected ports, and multi-level authorisation ensures only verified SX-Tool dealers and technicians can initiate a remote link — end-user vehicles, software and credentials stay protected throughout.

Frequently Asked Questions

Does SX-LINK work with the SX-Tool JLR diagnostic interface? Yes. SX-LINK is compatible with JLR ENET, ENET Wi-Fi adapters, the SX-Tool JLR diagnostic interface, and genuine JLR DoIP VCI hardware — anything that carries the ENET/DoIP session.

Do I need to open firewall ports or set up a VPN? No. SX-LINK handles routing through its own global server network. Both sides simply connect to the service, and the session establishes automatically.

Can I use SX-LINK for remote coding customer cars? That is its primary purpose — it is the infrastructure behind our own remote coding service. Your technicians can deliver the same service model to your own customers.

Which JET software does it support? JET Pro, JET Master, JET LS and SX-CAN — the full SX-Tool software family runs over SX-LINK sessions.
