The SeaLINK+8.SC (Model 2823) is a reliable, high-density USB serial adapter that simplifies multi-device connectivity. With eight serial ports that can each be configured for RS-232, RS-422, or RS-485 via software, you no longer need to open enclosures or manually adjust settings.

Perfect for field installations or industrial systems, this adapter keeps electrical interface settings stored locally, allowing you to move between systems or redeploy quickly without reconfiguration. With the included SeaCOM drivers, setup is seamless for Microsoft Windows environments, and each port is recognized as a standard COM port.
