Point-to-Point I/O Mirroring Configuration:

The digital inputs from one module are replicated on the other module (and vice versa).
Standard SignalFire Configuration:

Operates as a remote node with a standard SignalFire Gateway. All I/O data is available at the Gateway as Modbus registers. Supports Modbus writes to control the relay outputs. SignalFire node in a SignalFire network, providing longer-range as well as more sophisticated monitoring and control.
