The USB2-4COMi-TB is a rugged, industrial-grade USB to 4-port serial adapter designed for demanding RS-232, RS-422, and RS-485 applications. Each port features a 5-pin terminal block and is individually configurable via internal DIP switches, giving you precise control over signal types. With 15kV ESD and 600W surge protection, this adapter is built for harsh environments. It uses the high-performance FTDI FT4232H chipset and supports data rates up to 921.6Kbps with 2K transmit and receive buffers per port. Housed in a metal chassis with DIN-rail mounting support, it's a reliable solution for industrial communication expansion over USB.
