The RoamIO2 does not seem to be able to communicate with an ACX5740, why?
What must be done to get a RoamIO2 to communicate with an ACX57xx controller?
The ACX57xx must have comm1 configured as Infinet.
This is because the RoamIO2 hardware only communicates via the Infinet protocol (when running the InfinetServiceTool software) or BACnet protocol (when running the BACnetServiceTool software).
An ACX57xx is not communicating either of these protocols unless comm1 is configured for Infinet.
