Ok Cathy
Update done, talking to the mount ok looks like I owe you a drink.
Thank you for your help
It seems the rs232 com port was working and talking to the hand controller at first, then it will stop. I am thinking the baud rates maybe too fast or something else concerning the communication speeds. After great help from Cathy I pressed "Setup" in upgrade mode and the symbol "Lo" appeared. I then restarted the process and it worked.
