A name for a series of standards for serial binary single-ended data and control signals is RS-232 converter or Recommended Standard 232 connecting between Data Terminal Equipment and Data circuit-terminating equipment. It defines the electrical characteristics, timing and meaning of signals along with physical size and pin out of connectors commonly used in computer serial ports. To connect personal computers to modems, printers, UPS and data storage along with other peripheral devices this RS-232 was once commonly used.
The need of fiber optic converter is required to overcome these limitations due to the limited transmission, speed range and networking capabilities of RS232. With option like fiber optic converter that enables people to overcome the limitations posed by RS232, the latest technology advancement has offered us. Since it permits transmission over longer distance and at higher bandwidths fiber optic communications are greatly preferred and used. Moreover to electromagnetic interference, the signals in fiber optic travel with less loss and are also immune.
With the use of fiber-optic transmission to provide immunity from EMI/RFI interference RS232 to fiber optic converter secures data transmission. For applications where data transmission need to be protected from surges, electrical exposure, lighting, atmospheric conditions and chemical corrosion this converter is ideal solution. Benefits like wide bandwidth, immunity to EMI/RFI interference along with secure data transmission in the need for conversion arises because fiber optic transmission. RS232 to rs422 converter is being increasingly used.
Transmitting and converting full or half-duplex signals and their equivalents within a fiber-optic environment, RS232 to fiber optic converter is a point-to-point or point-to-multi-point connections.
Understand the concept of RS232 and serial interfacing in general. To make an RS232 interface with an interface IC, the MAX232 for example is the easiest way. With cost ranging in the $1-$3 range there are a great number of different dedicated chips available. One can have a reliable RS232 interface. By adding a few capacitors you can buy for about $7 as a kit for hobby work.
In terms of voltage swings, signal interference and radio frequency disturbances speed and distance interference can be available. Thus, the aim of secure data transmission no longer remains an impossible or difficult task, with the fiber optic converter. Thus rs232 to rs422 converter are being used increasingly.
