MB SD Connect C4 VMware Network Configuration

Here is the customer solution on Mercedes Benz MB SD Connect Compact 4 Network configuration on Virtual Machine.

“Troubled with connecting the MB SD Connect C4 MUX with the VM for a couple of days, and after many tries, I managed to work SD Connect with Green LAN Cable through VMWare. ”


VMWare has it’s own way of doing things.

Here is the solution for LAN cable:

* Open Virtual Network Editor and setup. (Do not remove any of the networks, somehow VMWare manages to not bridge the connection successfully)


* From the Virtual Machine Settings, configure the network


* From the Host Computer, configure the TCP\IP settings


* From the Virtual Machine, configure the TCP\IP settings


* You should be successfully pinging from VM


* SDNetControll will see your MB SD C4 multiplexer successfully ”

Hope it would help you if you also have the same problem.



MB SD Connect C4 and Dell D630 Full Kits Review

Here is the review on MB SD Connect c4 with dell d630 4GB full diagnostic system by a Poland  customer.



” It’s Philip From Poland, I bought one of these full kits after doing a lot of research from various vendors. The Service from from mbstartool.com always responded quickly, answering all questions I had. Shipping was very quickly, Help us declare a lower orice on the invoice, package ship via DHL  (approx. 3 days arrival).

The Dell630 is understandably second hand, and seems old, and had be resprayed (painted) but is otherwise fully functional. The latest 2015.12 MB software was installed and everything seems to work OK right out of the box, which is exactly as stated.

Cables, connectors and mux all appear to be pretty good quality, although the C4 didn’t have batteries installed (not sure you really need these anyway).

Wireless connection to the MB SD C4 seems to be intermittent – I got a few disconnects and crashes in Xentry (javaw.exe) on wireless, but on cable it has worked consistently well so far.

For people considering buying a kit like this for newer cars (e.g. New C Class), the only advice I can give is that the Xentry software on modern cars will only let you do tests – (i.e. No Adaptations or coding); everything requiring change will need Online SCN coding. It’s a great toolkit to have for diagnostics alone though.

Overall – I can highly recommend buying from this vendor since everything was as advertised, plus you have fast response on emails if you have issues or questions.

Thank you , would buy from you again ”
