Interface Converters, Serial Converters, and 
Range Extenders

RS-232, RS-485 and RS-422 are among the most successful and widely used serial interface standards for industrial applications. Although these standards are not directly compatible with each other, it is often necessary to communicate between them. In order to convert RS-232 signals to RS-485 or RS-422 signals a special device is required. The ESI family of interface converters are designed to easily convert data between all of these standards. The ESI automatically controls the direction of serial data eliminating the need for software flow control. 
Using a patented technique (Automatic Data Flow Control, ADFC™), ESI interface converters automatically adapt to any baud rate up to 115,200 baud and is independent of communications protocol. The ESI can be used in your industrial applications without any hardware or software changes.
