Depending on your specific requirements, it is likely that a combination of connection types will be
used. Connection to Remote Expansion Modules can only be done with RS-485. It is entirely possible
to connect controllers via ethernet and REMs by RS-485.
4-4.5 Connection of Innotech Legacy Devices
Connection of Innotech's legacy devices (non-Omni) is done using the Omni controller's RS-485
comms. The IG01 in the example below uses two comms ports to allow for data sharing.
