1-port RS-232/485/422 To Fiber Optic Converter
MODEL277 is a high quality industrial-grade bi-directional externally powered RS-232 / RS-485 / RS-422 to fiber optic converter (fiber optic modem) enclosed in a heavy-duty steel housing. Besides the capability of long distance data transmission, fiber lines are inherently resistant to EMI/RFI and transient surges including lightning; therefore, they are ideal for data communications near heavy electrical equipment and other electrical or atmospheric interference conditions. The fiber optic converter can extend the RS232 / RS485 / RS422 signal distance to up to 12.4 miles (20 km) using fiber optic cable. The RS232, RS485, and RS422 can be connected in any configuration; for instance RS232 can be converted to RS485 or RS422 via fiber. The unit supports serial data rates up to 460kbps and features auto-sensing data turnaround and therefore requires no flow control or any software drivers, The converter has no DIP switches or jumpers making it Plug-and-Play. MODEL277 has a terminal block connector for easy installation and either ST type or SC type connectors for the fiber optic links which needs to be specified. The media converter is wall, panel, or DIN rail mountable.
