ports utilization for Desktop Central MSP - Directly connections

ports utilization for Desktop Central MSP - Directly connections

Hi guys,
 
I need to install Desktop Central MSP trial version for the moment and I want to connect 3 remote client with the direct connection option.
Could you tell me all the correct ports to comunicate the central server with the client? I'd like to know enough if the connections must to be  bidirectional.  
 
Thanks,
Ryo
