  • Specification

The SeaLINK+2.SC OEM (Model 2223-OEM) is engineered for embedded and industrial systems where reliable serial communication is required over USB. It connects via an internal 2mm Molex header and provides two independent software-configurable ports. No jumpers or DIP switches are needed—interface selection and configuration are handled entirely by Sealevel’s driver software.

The adapter is ideal for ITX, EBX, EPIC, and other OEM platforms. Each port supports RS-232, RS-422, or RS-485, and settings are stored onboard, allowing the module to be re-used across multiple hosts without reconfiguration. Sealevel’s advanced state-machine architecture reduces CPU load while ensuring reliable communication at speeds up to 921.6K bps.

This USB-powered module includes power and activity indicators and is ideal for OEM designs requiring flexibility, compact size, and robust performance.
