C4 connect issues
What were the final configurations that work? In my case, I have a Toughbook and a C4 SDConnect. I get the following error:
"Initialization of diagnosis multiplexer failed.
The link between the diagnosis multiplexer and the diagnostic socket is interrupted.
The link between the diagnostic multiplexer and the diagnostic unit is interrupted.
The voltage supply at the diagnostic socket (circuit 30 and or circuit 31) is faulty.
when using SDconnect, check the connection status using Toolkit."
I checked the voltage using mux and it reports car voltage is 13.4V. I checked with self test signal and the mux flashes and beeps.
I followed the directions of the network connections as per the folder on the desktop, the lan ip settings set to 172.29.127.119/255.255.0.0 and the wireless at 192.168.2.221/255.255.255.0.
When I plug in the wire, it shows the wire icon in the Mux window. If I take the wire off, it shows the wireless icon in the Mux window.
Also, as per your experience, the IP addresses go to whatever the laptop came with and I have to reset each time.
Any help from the forum members is always appreciated. Thanks.
