Encrypted Etherpoll EEP-2

Encrypted Etherpoll EEP-2 Two Port Encrypted SCADA Serial Server

The EEP-2 Encrypted EtherPoll is a SCADA communications serial server that allows multi-drop devices to use Ethernet LANs. Using the EEP-2 AES-128 bit encryption, even the Internet can be used securely. The EEP-2 connects any async serial device through a LAN and between LANs via routers. The EEP-2 is designed specifically to support asynchronous polling protocols, such as Poll Select, Modbus, DNP3, IEC-60870-5-101, etc. The EEP-2 uses IP protocol, allowing the necessary data connection over a local LAN and across routed networks. The EEP-2 functions independently of the device protocol, allowing most 8 bit asynchronous protocols to be used with no configuration changes.

Typical Applications

• Connect a host computer to remote terminals that are polled using asynchronous polling protocols
  
• Connect SCADA host computers to RTUs
  
  
• Connect Poll Select host computers to terminals using Poll Select protocol
  
  
• Broadcast data from a single host port to multiple remote locations, such as multiple signs splaying identical data
  
  
• Migrate serial polled terminals to IP/ethernet based networks
  
  
• Securely operate SCADA systems over public networks, including the Internet
