DESCRIPTION

The EtherPoll is a SCADA communications serial server that allows multi-drop devices to use Ethernet LAN's. The EtherPoll connects any async serial device through a LAN and between LAN's via routers. The EtherPoll is designed specifically to support asynchronous polling protocols, such as Poll Select, Modbus, DNP, etc. These protocols are often error corrected, and the EtherPoll allows these protocols to work through routed LANs and over IP protocol networks. The EtherPoll uses IP protocol, allowing the necessary data connection over a local LAN and across routed networks. The EtherPoll functions independently of the device protocol, allowing most 8 bit asynchronous protocols to be used with no configuration changes. 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 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.
Instead of replacing your existing RTUs and SCADA system to go Ethernet, add the EtherPoll for a fraction of the cost.
For other applications (point-to-point direct RS-232 links or Point-to-multiple point dialed links ) see the EtherPath® single port serial server.
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.
