RS485 and RS422 standards are yet very much used, mainly in professional environments, when BUS communications are preferable to any other topologies. As examples we may have connectivity between a server unit and peripherals at sales points, retrieving data from a line of meters, or connecting PLC’s to a number of dispersed intelligent I/O units.
Plug and play, this RS232 to RS485/RS422 bidirectional protocol converter from Dynasys matches the communications’ formal distance of 1,2Km related to these standards, overcoming the constraints concerning the short distance allowed by RS232 – up to 15 m at 9600 bps – or the fact that RS232 only allows point-to-point communications.
This PROTOCOL CONVERTER also allows an INTELLIGENT operating mode, since it integrates a micro-controller, which allows four possible configurations, for controlling two digital outputs, from the state of one or two digital inputs also available. Thus, conditions are created for autonomously controlling basic processes.
