The Rocstor 6 ft FTDI USB-to-RS-232 adapter cable connects a computer’s USB 2.0 Type-A port to a male 9-pin DB-9 serial connection, making it suitable for notebook and desktop users who need a wired serial link at rates up to 115.2 kbit/s.
Recommended For
- IT technicians configuring or troubleshooting routers, switches, and other equipment with a standard RS-232 DB-9 console port can use it to connect a USB-A laptop to the device; COM retention is useful when they reconnect it during repeated service work.
- Field-service and maintenance staff working with legacy RS-232 equipment can use it to connect a USB-A computer to a compatible DB-9 serial port without relying on a built-in serial port; the 6-foot cable offers some flexibility when the computer is not right beside the device.
- Technicians or operators who use serial terminal or control software with older instruments and peripherals can use it when those devices specify RS-232 over DB-9 and the required communication settings are supported.
- Users whose Windows serial applications expect a consistent COM-port assignment can benefit from the adapter’s COM-retention feature when reconnecting the same cable or rebooting the computer.
