GENERAL DESCRIPTION
The 72-CNV-XX family of converters offer a flexible and reliable solution to the challenge of interfacing devices conforming to different serial communication standards. Grayhill converter products are designed for industrial environments. All communication lines have transient protection which other commercially available converters lack. The converters allow an RS-232 device (ie. PCs, PLCs, Embedded Controllers) to communicate reliably over long distances to multiple devices utilizing the RS422/485 standard. Reliability is an inherent benefit of the differential mode communication of RS422/485. Noise introduced onto the RS-422/485 link affects both the positive and negative side equally, preserving the integrity of the differential signal between them. Long distances and multiple slave devices are supported by the converters. In half-duplex (2-wire) RS-485 mode,

handshaking can be controlled from either end of the communication link. Typical applications involve connecting a host computer to remotely located serial devices such as printers, control equipment, or data acquisition devices dist……
