The SeaLINK+2.SC Kit (Model 2223) is a rugged USB-to-serial adapter with two individually software-configurable RS-232, RS-422, or RS-485 ports. It offers high-speed, low-overhead communication with plug-and-play functionality and compatibility with legacy COM port software..
The SeaLINK+2.SC Kit (2223) offers a powerful and compact solution to connect two serial devices over a single USB port. Each DB9M port is individually software-configurable for RS-232, RS-422, or RS-485, allowing easy deployment across various equipment environments without physical reconfiguration.
The adapter uses a state-machine architecture to reduce host CPU load while delivering fast, reliable communication. With no jumpers or internal switches to set, installation is quick and field service is simplified. All port configurations are stored locally, so if the adapter is moved or the host system is upgraded, it retains the previously saved settings.
Housed in a robust plastic case, the 2223 is suitable for industrial, commercial, and OEM applications. The included SeaLATCH USB cable ensures a secure connection using a metal thumbscrew, ideal for vibration-prone or mission-critical installations.
