Industrial RS232 RS22 RS485 Fiber Media Converter Double Ring Type
Industrial 1~4Ch RS232/RS22/RS485 Double-ring Fiber Media Converter
Fiber Media Converter Advantages
► Based on proprietary integrated circuit;
► Provide 1-4 independent serial ports (RS232/422/485 optional) channel, physical isolation from each other, there is no correspondence between the
► Provide two fiber optic lines, it can automatically switch when the line failure, ensuring communication is normal.
► RS232 / 485/422 interface, optional three data, RS232 supports 3-wire RS232 (TXD, RXD, GND), flow control support CD, DSR, CTS,
► RS232 /485/422 channels can be transmitted from 0-115200 baud asynchronous serial data adaptive

Overview
The LNK-GYS200 series is Ring Optical data type provides 1~4Ch RS232/422/485 in the optical fiber transmission, support a variety of fiber optic network topologies: point to point communications, chain network, star and redundant ring network protection, self-healing network topology, and on this basis, the networking is more complex network topologies, with a self-healing ring network protection. The product breakthrough contradictory legacy serial interface communication distance and speed, but also to solve the electromagnetic interference, ground loop interference and lightning damage problems, greatly improving the reliability of data communications, security and confidentiality.
