Interface RS-232
The RS-232 specification allows for reliable data transmission from one transmitter to one receiver at data rates of up to 20 kbps over relatively short distances (up to 50 feet). On more recent RS-232 transceiver chips, data rates of up to 1 Mbps are achievable over shorter distances (up to 5 feet). The most common applications for RS-232 transceivers are computers and peripherals, mobile phone data cables, and diagnostic data ports.

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.
