Introduction

Fiber optic transmission offers the benefits of wide bandwidth, immunity to EMI/RFI interference, and secure data transmission. The ADAM-4541/ ADAM-4542 can be used as an RS-232/422/485 point-to-point or point-to-multipoint connection for transmitting and converting their equivalents within a fiber optic environment. Fiber optics are the perfect where the transmission medium must be protected from

conditions or The ADAM-4541/4542 is

various machinery equipped with 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) m.

When using the converter in combination with other ADAM modules, do not change the setting of the converter, sinc e ADAM modules have a fiXed data forma t of ten data bits. The option of changing to 9, 11 or 12 bits is for use with other modules (other than ADAM modules) that have different data formats.
