1.7 Communications
The RTU includes four serial communication ports, two Ethernet ports, and one Micro A-B USB port.
The Ethernet ports reside on the top of the CPU module and use RJ-45-style 8P8C sockets. Each
port supports a maximum of six concurrent TCP connections (sockets). The Micro A-B USB port
resides on the front of the CPU module and supports DNP3 communication. The serial ports allow
communication using DNP3, Modbus slave and Modbus master protocols.
