The FR485 operates as a transparent repeater only, which does not perform any additional routing functions and requires no additional software configuration. Led indication is provided on all transmit and receive fiber channels. The FR485 is available as a single or dual channel. HomeWorks Illumination, HomeWorks QS, and RadioRA 2 RS-485 link wiring is commonly implemented utilizing a four conductor cable consisting of one pair of 22AWG twisted and shielded (communication) and one pair of 18 AWG (power). It is possible, however, to use fiber optic cable and modems to extend. Moxa's industrial-grade serial-to-fiber optic converters can convert RS-232/422/485 to optical fiber, which provides users with an easy and reliable way to communicate with their serial devices. This device enhances communication reliability in industrial environments by bridging traditional RS485 networks. So when you need to connect the RS485 devices that are very far away, you often need to convert the RS485 signal into a fiber optic signal. It converts electrical RS-485 signals into optical signals, ensuring high-speed, interference-free data transmission. All protocols with 10/11-bit UART data format and NRZ data.
