CommFront offers a range of high-quality, industrial-grade, port or externally-powered RS232 to RS422 converters. These plug-and-play converter products operate within a wide temperature range (-40ºF to 185ºF / -40ºC to 85ºC), feature 600W surge protection and 15kV static protection, and come with built-in 120 Ohm terminators for easy installation. Whether your environment is commercial or industrial, "clean" or "noisy"*, our RS232 to RS422 converter products provide safe, easy, and cost-effective solutions for your data-conversion applications.

* A "noisy" environment is an area surrounded by ground loops, transient surges and spikes, which could potentially harm your expensive equipment such as computers and data communication devices. The CommFront opto-isolated RS232 to RS422 converters and isolators provide simple and effective ways to protect your devices from such potential harms.
