This ICUSB232SM3 3ft USB to Serial Adaptor Cable from StarTech.com lets you connect DB9 RS232 serial devices to your laptop or desktop computer through an available USB port, as though the computer offered an onboard DB9M connector. Unlike typical USB to serial converter cables where the conversion takes place at the DB9 end, the ICUSB232SM3 features a converter chip on the USB end. Converting at the USB source overcomes the 15ft technical limit of USB cables, allowing for a much greater serial DB-9 extension cable. Simple to install and use, this USB to Serial adaptor is a cost-effective solution that bridges the compatibility gap between modern computers and legacy serial peripherals. It is backed by a lifetime warranty and free lifetime technical support. * Bus type: USB 2.0 * Cable length: 900mm * Connector type(s): DB-9 (9 pin, D-Sub) male, USB A (4 pin) male * Enclosure type: Plastic * Interface: Serial * Max baud rate: 921.6 kbps * OS compatibility: Windows® 10, 8 / 8.1, 7, Vista, XP, 2000, ME, 98SE, CE 4.2, 5.2 * Ports: 1 * Manufacturer's part: ICUSB232SM3 https://elecena.pl/product/27179992/startech-com-icusb232sm3-3ft-usb-to-rs232-db9-serial-adapter-cable-m-m 2024-11-08 https://elecena.pl/product/27179992/startech-com-icusb232sm3-3ft-usb-to-rs232-db9-serial-adapter-cable-m-m 2025-03-31 https://elecena.pl/product/27179992/startech-com-icusb232sm3-3ft-usb-to-rs232-db9-serial-adapter-cable-m-m 2025-04-30 https://elecena.pl/product/27179992/startech-com-icusb232sm3-3ft-usb-to-rs232-db9-serial-adapter-cable-m-m 2025-06-03 https://elecena.pl/product/27179992/startech-com-icusb232sm3-3ft-usb-to-rs232-db9-serial-adapter-cable-m-m 2025-08-01 https://elecena.pl/product/27179992/startech-com-icusb232sm3-3ft-usb-to-rs232-db9-serial-adapter-cable-m-m 2025-10-02 https://elecena.pl/product/27179992/startech-com-icusb232sm3-3ft-usb-to-rs232-db9-serial-adapter-cable-m-m 2026-03-09 https://elecena.pl/product/27179992/startech-com-icusb232sm3-3ft-usb-to-rs232-db9-serial-adapter-cable-m-m 2026-04-02
