Part No: 2004542003
5th Edition
July 2021
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.
