ADAM-4541/4542 Features • • • • • • • • • • • • • • • Fiber Optic to RS-232/ 422/485 Converter Compact size economizes space Direct plug-and-play Easily mounted on a DIN-rail, panel or piggyback Transmission speeds of up to 115.2 Kbps Optical fibers enable transmission of 2.5 km for ADAM-4541 and 15 km for ADAM-4542 Half/Full-duplex, bidirectional transmission mode Avoids lightning strikes and EMI/RFI interference Prevents damage from electrostatic discharge Stable and error-free data transmission Automatic internal RS-485 bus supervision No external flow control signals required for RS-485 Transient suppression and over-current protection on RS-422/ 485 data lines Reserved space for termination resistors LED for power and data flow indication Power requirement: +10 to + 30 VDC Introduction Fiber optic transmission offers the benefits of wide bandwidth, immunity to EMI/RFI interference, and secure data transmission. ADAM-4541/ ADAM-4542 can be used as an RS-232/422/485 point-to-point or pointto-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. The ADAM-4541/4542 is specifically designed to link various machinery equipped with an RS-232/422/485 communication ports (such as computer systems or manufacturing machines). Using standard ST connectors, the module's fiber optic ports can accommodate a wide range of fiber optic cable sizes, including 62.5/125 (9/125) µm.
