3. ADAM 4542 Fiber Optic to RS 232 422 485 Converter Overview Fiber optic transmission offers the benefits of wide bandwidth immunity to EMI RFI interface and secure data transmission The ADAM 4542 can be used as an RS 232 422 485 point to point or point to multipoint connection for transmitting and converting full half duplex signals and their equivalents within a fiber optic environment Fiber optics are the perfect solution for applications where the transmission medium must be protected from electrical exposure lighting atmospheric conditions or chemical corrosion The ADAM 4542 is specially designed to link various machinery equipped with RS 232 422 485 communication ports such as computer systems or manufacturing machines Using standard SC connectors the module s fiber optic port can accommodate a wide range of fiber optic cable ADAM 4542 also supports the redundancy requirement You can use two pairs of ADAM 4542 for a redundant architecture This special design offers higher reliability Packing List Before you begin installing your module please make sure that the following materials have been shipped 1 x ADAM 4542 Module with DIN rail mounting bracket 1 x ADAM 4542 User Manual 1 x Panel Mounting Bracket 1 x Cable for DB 9 to 3 wired If any of these items are missing damaged contact your distributor or sales representative immediately For more information on this and other Advantech product
