Module makes light work of RS232/485 connections
August 2007
Industrial Computer Hardware
Advantech's Adam-4541 module has been designed to link equipment with RS232/422/485 communication ports such as computer systems or manufacturing machines. It provides stable and error-free data transmission with transmission speeds of up to 115,2 Kbps while the optical fibres enable transmission up to 2,5 km.
Fibre-optic transmission offers the benefits of wide bandwidth, immunity to EMI/RFI interference, and secure data transmission. The module can be used as an RS232/422/485 point-to-point or point-to-multipoint connection for transmitting and converting full/half-duplex signals and their equivalents within a fibre-optic environment. Fibre-optics is the perfect solution for applications where the transmission medium must be protected from electrical exposure, lightning, atmospheric conditions or chemical corrosion.
Operating in a half/full-duplex, bidirectional transmission mode the device provides transient suppression and over-current protection on RS422/485 data lines with automatic internal RS485 bus supervision. No external flow control signals are required for RS485 and provision is made for the installation of termination resistors.
