Overview

The Patton Electronics 222N9SF is a compact, interface-powered RS-232 to RS-422 converter designed to extend serial communication distances up to 4,000 ft (1,219 m) over two twisted pairs. This converter eliminates the need for external power by drawing ultra-low power from EIA data and control signals, making it ideal for remote or hard-to-power installations. The 222N9SF features a DB-9 female RS-232 connector and supports asynchronous data transmission at rates up to 19,200 bps. It converts EIA-232 data to EIA-422 in full-duplex, 4-wire transmit mode while wiring RS-232 control signals (RTS to CTS, DTR to DSR and DCD) together for simplified connectivity. Built-in surge protection safeguards connected devices from transient voltage spikes, ensuring reliable operation in industrial environments. The converter measures 2.50 x 1.20 x 0.75 inches (6.4 x 3 x 1.9 cm) and is CE approved for global deployment. Compatible with Patton’s 222N series, the 222N9SF supports DCE/DTE selectable interfaces and offers flexible connectorization options for RS-422 twisted pairs.
