Isolated RS-232

Analog Devices offers a wide range of RS-232 transceivers to suit many applications. As RS-232 cable networks and the systems to them can be vulnerable to voltage spikes and ground loops, we have developed a number of innovations that protect against these issues and create an isolated RS-232 environment. We accomplish this through our isoPower® integrated dc-to-dc converters, as well as our iCoupler® technology, which enable the power isolation and signal isolation required for system reliability in a noisy environment.
