ADAM-4541中文资料Multi-mode Fiber Optic to RS-232/422/485 Converter数据手册Advantech规格书

描述 Description

Fiber optics transmission offers the benefits of wide bandwidth, immunity to EMI/RFI interference, and secure data transmission. ADAM-4541 can be used as an RS-232/422/485 point-to-point or point-to-mutipoint connection for transmitting and converting full/half-duplex signals and their equivalents within a fiber optic environment. Fiber optics is the perfect solution for applications where the transmission medium must be protected from electrical exposure, lightning, atmospheric conditions or chemical corrosion.
