RS-422/485 Repeaters

Most industrial computer systems come with standard RS-232 serial ports. Though widely accepted, RS-232 has limited transmission speed, range and networking capabilities. The RS-422/485 standards overcome these limitations by using differential voltage lines for data and control signals. The RS-422/485 repeater simply amplifies, or boosts, existing RS-422/485 signals to enable them to cover longer distances. It extends the communication distance by 1200m (4,000 ft.) or increases the maximum number of connected nodes by 32.

RS-232/422/485 Converters

The serial media converters provide conversion between serial networks and other media. They can transparently convert RS-232 signals to RS-422/485 signals, as well as convert RS-422/485 to RS-232 signals without changing the PC's hardware or software. The converter lets you easily build an industrial grade, long distance communication system with standard PC hardware.

RS-232/422/485 to Fiber Optic Converters

Fiber optic transmission offers the benefits of wide bandwidth, immunity to EMI/RFI interference, and secured data transmission. The fiber-optic converter is 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 optics environment. Fiber optics is the perfect solution for applications where the transmission medium must be protected from electrical exposure, lightning, atmospheric conditions or chemical corrosion.
