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 RS-
