Eaton Tripp Lite U208-004-IND 4-Port RS-422/RS-485 USB to Serial FTDI Adapter with COM Retention (USB-B to DB9 F/M)

Deploy dependable serial connectivity for security, surveillance and industrial monitoring with the Eaton Tripp Lite U208-004-IND 4-Port RS-422/RS-485 USB to Serial FTDI Adapter. This professional-grade serial hub turns one USB port into four DB9 interfaces, enabling you to connect modems, barcode scanners, access control panels and legacy controllers without extra power. The built-in FTDI chipset and COM retention simplify IT management by preserving COM assignments across reboots and disconnections, reducing configuration time for critical systems. Each port features independent DIP switches to auto-detect RS-422/RS-485 or force 4-wire mode, giving you flexible integration for field devices and networked sensors. With USB 2.0 compatibility, serial speeds up to 1 Mbps and ±15kV ESD protection in a steel, wall-mountable housing, it’s engineered for uptime in surveillance racks, control rooms and industrial sites. LED transmit/receive indicators make troubleshooting fast and efficient. Ideal for security integrators and IT teams upgrading legacy devices, the U208-004-IND streamlines serial deployments—add it to your kit to accelerate monitoring and access control projects.
