When using SDconnect, check the connection status using the Toolkit
Analysis from technician :
pay attention to the icon in the bottom right corner
When the computer starts, connect to the Device 21(SDconnect multiplexer)
The cross “x” there means bad communication or some other causes
Optional solutions for bad communication:
1- cable problem
1) the cable from the car to the mux
you may replace it if the mux is not light on
2) the cable from the laptop to the mux
Go to Local Network Connection
Plug and unplug the SD C5 com port for times to see if there is change in Local Network Connection or not.
If not, change another computer to try again, also in this way.
But, if still not any change in any computer, you may replace the LAN cable with another one to have a try.
2- mux problem
If you still have the same problem, it means that the mux is not ok
you may run star utilities you have 2 ways
1) if you hear the mux ticking means you have to check the car-mux cable
2) if you did not hear mux ticking means the laptop-mux cable is not ok OR the mux is not ok
But if unluckily with all solutions before, please send back your unit to the vendor for repairing.
