The EtherPoll supports serial interface speeds up to 230 Kbps. Since it uses the UPD/IP protocol, overhead is much lower than it would be if TCP/IP were used since there is no "session setup" or "session breakdown" with each connection. Up to 32 remote Etherpolls may be used with each host EtherPoll.
The EtherPoll serial interface may be configured to use either RS-232, 4-wire RS-232/485, or 2-wire RS-485. The ethernet interface is auto-sensing or configurable for 10BaseT or 100BaseT.
The EtherPoll can be managed directly through the server's physical port as well as remotely from other network locations. Remote configuration is supported using TCP/IP (telnet) or any web browser.
Security features embedded in the EtherPoll include fine-grained configuration and management controls as well as the ability to turn off remote management functions.
Instead of replacing your existing RTUs and SCADA system to go ethernet, add the EtherPoll for a fraction of the cost. Or, use the EtherPoll as a step when deploying enterprise-wide ethernet based replacement devices. Install the network at your own pace while the EtherPoll allows connectivity for older serial devices.
A unique RTS/CTS toggle function allows the EtherPoll to control a serially attached multi-drop modem or radio.
For other applications (point-to-point direct RS-232 links or Point-to-multiple point dialed links ) see the EtherPath® single port serial server. The EtherPath uses TCP/IP. An applications note comparing the two products, ""EtherPath vs. the EtherPoll, Selecting the best product for your application" is available here.
A companion product, the EtherGate is appropriate for applications using DNP-3 or Modbus and other protocols in bandwidth limited networks. The EtherGate is protocol aware, and "looks inside" the protocol blocks for addressing information. This allows it to target each remote RTU individually instead of broadcasting polls to all remotes. The EtherGate uses UDP/IP. Its data sheet is here.
OEM manufacturers can design the EtherPoll into their products or use it as an add-on method to gain ethernet connectivity. DCB supplies the EtherPoll to many other companies and can provide custom firmware for specific applications.
