Advantech's ADAM-4541 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. Compact in size, these modules provide stable and error-free data transmission in direct 'plug-and-play' conditions. They are easily mounted on a DIN rail, panel or can be piggybacked. Transmission speeds of up to 115,2 kbps are possible, and with the fibre-optics, transmission up to a distance of 2,5 km can be accomplished.
Protection is provided against lightning and EMI/RFI interference, and no external flow control signals are required for the RS485 mode. Automatic, internal RS485 bus supervision is supplied, and power and data flow indication is given via the LEDs on the front panel. The modules are able to link various machinery equipped with RS232/422/485 communication ports such as computer systems or machines used in manufacturing processes.
By utilising fibre-optics, ground loops and spark hazards are eliminated and operation in flammable areas is possible. Standard ST connectors allow the module's fibre-optic ports to accommodate a wide range of fibre-optic cable sizes.
