TOPIx via ENET: Dealer Cloud, $29 Cable

TOPIx Cloud is JLR's official online platform. The DoIP ENET addon bridges it to a standard ENET cable — no $2,299 VCI required.

JLR ENET Cable Guide Starter Pack — $119.99

01 / THE STACK

Four Components, One Session

TOPIx via ENET is a software bridge from SX TOOL Co., Ltd.: it auto-detects your ENET connection, establishes the DoIP session, and tunnels it to TOPIx Cloud — JLR's official online diagnostics, workshop manuals, TSBs and ECU programming platform for 2017+ vehicles.

Component	What It Is	From
1. TOPIx Cloud access	Official JLR online subscription — manuals, wiring, TSBs, guided tests, programming	Daily pass from $99
2. DoIP ENET addon	Protocol bridge software: auto-detects ENET, translates DoIP, bridges the cloud session	SX TOOL license
3. ENET cable	OBD2 to RJ45 or USB-C; Type-C version adds live voltage display	From $19.99
4. Team support	WhatsApp/Telegram expert assistance, remote log review	Included with addon

02 / HOW IT WORKS

The 4-Step Session

1. Connect — ENET cable into the OBD2 port; laptop network set to automatic IP
2. Launch the addon — it detects the ENET link and establishes DoIP with the vehicle gateway
3. Sign in to TOPIx — your cloud credentials; the addon bridges the session end-to-end
4. Diagnose & program — DTCs, live data, ECU programming at 100 Mbps ENET speed

The addon works alongside SX-TOOL, JET-PRO and JLR Pathfinder workflows on Windows 10/11. For vehicles 2005–2016, use JLR SDD instead — the European Starter Pack bundles both eras.

03 / WHY IT MATTERS

What This Replaces

Without the bridge, TOPIx Cloud programming expects the official JLR DoIP VCI — a $2,299 interface. The addon makes the cloud platform hardware-agnostic over a standard ENET cable. For owner-level diagnostics and CCF work you may not even need TOPIx: Pathfinder covers most of it locally. TOPIx via ENET is for when you need official workshop data and cloud programming on 2017+ vehicles — see the honest comparison on ENET vs DOIP VCI.

?? / FAQ

Frequently Asked Questions

Which vehicles does TOPIx via ENET cover?

All JLR vehicles with the ENET/DoIP diagnostic port — 2017 onwards, including Defender L663, Range Rover L405/L460, Velar, Discovery 5 and I-PACE. The full list is on the compatibility matrix.

Is this the same as buying a JLR DoIP VCI?

No — the VCI is a hardware multiplexer with official support. TOPIx via ENET is a software bridge that achieves the same cloud connectivity over a standard ENET cable. Flash-critical workshop fleets may still prefer the VCI; the comparison page breaks down when.

Do I need Pathfinder as well?

They answer different questions: Pathfinder is the local diagnostic application; TOPIx Cloud is the online data and programming platform. Many JLR users run both — the addon bridges whichever session you start.
