Hi Yi- 

I have experienced the "Failed to connect to real time controller" problem 
twice in the past two months on my Zeiss 510 Meta. 

There is a secondary computer or controller in the large module that 
contains the lasers and electronics.  This secondary computer is connected 
to the Windows computer by an internet cable.  When you start the Windows 
program, you should see at the bottom right of the monitor on one of the 
icons a message indicating "Real Time Connection/Speed 1Gbps/Status 
Connected" 

The first time I experienced the "Failed to connect to real time 
controller", the icon on the Windows screen also indicated that the Real 
Time Connection was Not Connected.  That time I could not get the system to 
work without a service call. 

The second time, the icon on the Windows screen indicated that the Real Time 
Connection was still Connected at 1Gbps.  If I shut down the system for 
30-60 minutes (5 or 10 minutes wouldn't work), then I could get the system 
back up and working.  It was as though there was a heating issue or 
something. 

In both cases, the final solution was for Zeiss to replace that secondary 
computer in the electronics module.  The system worked fine after that. 

Hope this helps-
Melinda
