Dear Sirs

"Test passed going to standby mode " and CDU closed

Could you please help me about this

Kindly regards

P.S: I did not do any update , My system is Win7 . FSX , Prosim

When the cdu's V1 go into standby mode it means they receive no data from the software.
* Have you checked if cables/hubs are connected ?
* Has your prosim setup become corrupt. Please check if the correct commports are configured in prosim
