The Openport 2.0 interface acts as a bridge, allowing Xentry to communicate with your Mercedes using the standard J2534 protocol. This has made it an accessible alternative to Mercedes' own proprietary and often expensive multiplexers like the SD Connect C4 or C5, with many users reporting the Openport 2.0 works with the Xentry Passthru version.
When performing coding or programming, always use a reputable battery charger to keep the vehicle's voltage stable ( >12.5Vis greater than 12.5 cap V
While the Openport 2.0 is excellent for diagnostics, it has specific limitations compared to the official SD Connect C4/C6: Xentry Passthru Openport 2.0
Windows 10/11 (64-bit recommended), at least 4GB RAM, and ample storage.
Read and clear fault codes (DTCs), view real-time live sensor data, actuate components for testing, perform adaptations, initialize new modules, and run guided troubleshooting procedures. The Openport 2
is a specialized diagnostic software used for troubleshooting, coding, and vehicle health assessment on Mercedes-Benz vehicles. Unlike the standard OpenShell version designed for factory multiplexers, the Passthru version is built for the SAE J2534 standard, allowing it to work with third-party vehicle communication interfaces (VCIs).
Generally works on vehicles from 2003 and newer. It does not support older models requiring the 38-pin connector or HHTWIN (High Hand Tester). Read and clear fault codes (DTCs), view real-time

The combination of bridges the gap between everyday Mercedes-Benz enthusiasts and the service bay. It completely eliminates the need for expensive proprietary hardware, providing a gateway to deep, granular vehicle data, customizations, and diagnostic troubleshooting.
Xentry Passthru allows for "Variant Coding" (changing toggles within existing software, such as disabling the seatbelt chime or changing fuel tank capacities). However, you should using an Openport 2.0. The standard CAN bus structure utilized by pass-thru devices lacks the speed and error-correction protocols required for massive firmware transfers, which can permanently ruin the target module.
