However, the standards are now generally indicated as "EIA" standards to Where previously marked with the prefix "RS" to indicate recommended standard Practical problems that might be encountered in a typical network. The Electronics IndustryĪssociation (EIA) has produced standards for RS485, RS422, RS232, and RS423 Standards have been developed to insure compatibility between units providedīy different manufacturers, and to allow for reasonable success in transferringĭata over specified distances and/or data rates. Half the time for the signal to travel from the transmitter to the receiver. The connection between two or more elements (drivers and receivers) shouldīe considered a transmission line if the rise and/or fall time is less than Reliable data communications can be difficult in the presence of induced noise, ground level differences, impedance mismatches, failure to effectively bias for idle line conditions, and other hazards associated with installation of a network. Line drivers and receivers are commonly used to exchange data between two or more points (nodes) on a network. FOR RS485, RS422, RS232 AND RS423 Introduction
