XENTRY ENET Cable Configuration, Step by Step

The configuration guide Mercedes DIYers search for: connect XENTRY to any DoIP Mercedes with a $29.99 ENET adapter instead of a four-figure MUX.

01 / BEFORE YOU START

What You Need

A DoIP Mercedes (2016+; W205/W213/W222/X253/V167/EQ — check the matrix)
An ENET adapter — Type-C with volt display recommended so you can watch battery voltage
Windows 10/11 laptop with XENTRY/DAS installed
Battery maintainer for any session longer than a quick scan

Safety: XENTRY sessions can run long. Confirm 13.0V+ on the adapter's volt display before guided tests or actuations — low voltage is the top cause of failed sessions.

02 / STEP 1–2

Network Adapter Setup

Step 1 — Plug the ENET adapter into the OBD2 port and connect it to your laptop (USB-C direct, or Ethernet port with the RJ45 cable). Windows will identify a new network interface.

Step 2 — Set the adapter to obtain an IP automatically (DHCP/APIPA). The Mercedes DoIP gateway hands out link-local addresses in the 169.254.x.x range. Verify with ipconfig: you should see a 169.254 address on the ENET interface within 30 seconds of ignition on.

03 / STEP 3–4

XENTRY VCI Selection & Connection Test

Step 3 — In XENTRY configuration, select the Ethernet/DoIP VCI (often listed as 'Ethernet VCI' or 'DoIP interface') rather than SDconnect or eCOM. Save and restart the XENTRY session.

Step 4 — Start a new session. XENTRY should discover the DoIP gateway, read the VIN automatically, and populate the vehicle data card. If the VIN appears, your ENET configuration is complete — quick test, control units and guided functions are now available.

04 / COMMON ERRORS

If It Does Not Connect

Symptom	Cause	Fix
No 169.254 address	Firewall or wrong adapter profile	Disable firewall on the ENET interface; set network profile to Private
VIN not read	VCI type set to SDconnect	Switch VCI to Ethernet/DoIP in XENTRY config
Drops mid-session	Battery sag	Attach maintainer, confirm 13V+ on volt display
Works on one car, not another	Target car is pre-DoIP (CAN)	Older chassis need a MUX — ENET cannot connect

05 / NEXT LEVEL

DTS Monaco & Vediamo Over the Same Cable

Once XENTRY connects, the same ENET link serves DTS Monaco (with the correct CBF/SMR-D project for your chassis) and Vediamo for variant coding. The interface configuration is analogous — select DoIP/Ethernet and let the tool discover the gateway.

?? / FAQ

Frequently Asked Questions

Do I need a special 'XENTRY cable'?

No. Listings selling a dedicated 'XENTRY cable' are selling the same standard ENET/DoIP cable. Any correctly wired ENET adapter works — the configuration above is what actually matters.

Does this work for SCN online coding?

The ENET adapter provides the vehicle link for any XENTRY function, but SCN/online functions additionally require Mercedes-Benz dealer credentials and a valid XENTRY subscription — the same requirement as with genuine hardware.

Which adapter do you recommend for XENTRY?

The Type-C adapter with volt display. XENTRY sessions are long, and watching live battery voltage on the adapter prevents the low-voltage session failures that fill forum threads.

Will this void my warranty?

Reading diagnostics does not modify the vehicle. Variant coding changes configuration — use the same judgment you would with any diagnostic tool, and keep a record of original values.
