ems recycling

[acst12]

efis 100 / ems 120 factory installed on a CZAW sportcruiser. We are having persistent difficulties with the EMS recycling at will and "network connection error" being displayed on EFIS. Have replaced EMS earlier with a new unit and have updated to 5.1 since. Aircraft functioned ok for abot 3 hours and has now gone back to recycling sometimes in flight (very disconcerting!) or on ground.
Any advice would be appreciated.

Does the network connection error occur at the same time as the EMS recycling? Is the problem with the new unit the same as the last one? If so, I'd be investigating wiring issues first.
