## Long description

The Industrial RS232 to RS422/485 Serial Port Converter StarTech IC232485S converts an RS232 data signal to RS485 (2- or 4-wire) or RS422 and vice versa. Designed for industrial applications, the adapter supports baud rates up to 921.6 Kbps, provides 15kV ESD protection on all signal pins, and comes in a sturdy, wall-mountable steel housing with Power, Tx and Rx LED indicators. The unit accepts 110–240 V input voltage and supports communication distances up to 4000 ft (1200 m). It is CE-, FCC- and REACH-compliant and includes a 2-year manufacturer warranty and free lifetime technical support.
Advantages
This serial converter offers integrated 15kV ESD protection to safeguard sensitive industrial control equipment, automatic detection of baud rate and interface mode (with a manual DIP switch available), and high-speed data transfer up to 921.6 Kbps. The compact steel enclosure is wall-mountable for convenient installation and includes LED indicators for power and transmit/receive status.
Suitable for
Connecting RS232 devices to RS485 or RS422 networks in industrial control systems
