Earlier EIA suggested use of the prefix RS before cables, and hence they were labeled as RS232 and RS485. This ensures compatibility between devices provided by different manufacturers, and allows for better and smooth transfer of data over long routes and also for improved data rates. There are organizations like Electronic Industry association (EIA) and Telecommunication industries Association (TIA) that set the standards for the production of cables and other tools used in setting up of network. ![]() ![]() It is difficult to set up a network with smooth data transfer if there is noise, ground level differences, mismatch of impedance and other dangers present. RS232 and RS485 are standards for data cables. To exchange data between nodes on a network, the most commonly used tools are line drivers and receivers.
