It has been observed that the CMM-Manager connection with the I++ Server times out and fails to connect in some cases. 

One possible reason for this timeout could be due to a large number of tips in UCCServer. 

1. Increase the timeout value in the "IQIppDme.ini" file. 
   
1. Close CMM-Manager application
   
2. Browse to the "C:\ProgramData\QxSoft\CMM-Manager 2020\Driver" directory
   
3. Edit the IQIppDme.ini file
   
4. Replace the exiting "TIMEOUT" line with this:
   
1. ​​​​TIMEOUTS 500 1000 2000 5000 10000 30000 120000 // short, medium, long in milliseconds
   
5. Increase the last value to 180000 or larger value to accommodate longer sync time.
   
6. Save and close the file
   
7. Launch CMM-Manager and connect
   
2. If the configuration permits switch to the Renishaw UCC Direct 2.0 driver option
   
1. For more information, refer to the Renishaw - UCC Direct 2.0 (DCC) - Setup/Upgrade CMM-Manager guide.
   
2. This may require assistance from your service provider/reseller or QxSoft support.
