Serial-to-Ethernet Converter for Poll/Response Networks

Ideal for SCADA fiber optic networks, a new Serial-to-Ethernet Converter that converts RS-232, RS-422 or RS-485 asynchronous data to packets for poll/response transmission over Ethernet neworks is now available from TC Communications.

The Model TC3420 RS-232/422/485 Ethernet Converter Multi-Poll is compatible with all popular Ethernet Switches and similar devices. It is transparent to data or communications protocols and can be configured in bus, ring or redundant ring topologies. A web-based user interface (e.g. browser) is provided to view or change networks settings such as IP addresses.

Configured Master/Slave, the TC3420’s are typically used to link serial data RTUs and PLCs to a host controller or CPU over an Ethernet network in Utility, SCADA & Process Control LANs. An extreme temperature version (-40o to +80o) is available for harsh environments.

Diagnostics include local/remote loopback, alarm relay and a built-in Test Signal Generator to verify both device and fiber optic link operations.
