The EPIC Controller has two Communication Ports. One port is used to communicate to HindlePower devices, such as chargers, internal to the console. The second port allows the user to remotely observe status, or perform functions, that are accessible from the EPIC Controller front panel display. The user communication port supports DNP3 Level 2 and Modbus SCADA protocols over 2-wire RS-485 at BAUD rates from 9600 to 115.2K.

EPIC has one (1) standard RJ-45 Ethernet connector and supports copper 10/100 Mbps Ethernet connections. It supports multiple protocols (Modbus and DNP3) simultaneously.
