This USB-A to RS232 Null Modem Cable from StarTech provides a reliable way to connect serial devices to modern computers that lack traditional serial ports. It uses the FTDI FT232R chipset to ensure compatibility and performance, making it ideal for industrial, networking, or embedded systems applications. The cable includes both nuts and screws for securing it to a serial device, offering flexibility in installation. The LED indicators help users monitor data transmission and reception, as well as confirm successful USB enumeration.
The adapter supports multiple operating systems including Windows, macOS, ChromeOS, and Linux. It automatically installs drivers on Windows 7 and newer, macOS 10.15 and above, and Linux. COM port retention ensures that the port number remains consistent even after disconnection or reboot, simplifying setup and reducing configuration issues. The cable is designed for durability with a solid TPE housing and Level-4 ESD protection, making it suitable for environments with electrical interference or harsh conditions.
The cable is built with copper shielding to minimize electromagnetic and radio frequency interference, ensuring clear signal transmission. Gold-plated connectors improve conductivity and reduce signal loss. The operating temperature range of -40°C to 80°C makes it suitable for use in extreme environments. The compact design allows for easy portability, while the 1-foot length provides sufficient reach for most desktop setups.
The cable is particularly useful for connecting legacy serial devices such as modems, industrial controllers, or laboratory equipment to modern computers. It eliminates the need for cross-wired cables or additional adapters by resolving DCE/DTE conflicts directly. Users can easily replace the DB9 nuts or screws depending on their device requirements, enhancing versatility.
