C2G Port Authority 1.5ft USB to DB9 Serial Adapter Cable with RS-232 Support, 230 Kbps Data Transfer, and IRQ-Free Operation
The C2G 26886 is a 1.5-foot USB to DB9 serial adapter cable that connects legacy RS-232 serial devices to any available USB Type A port on a laptop, desktop, or tablet. A male USB Type A connector on one end and a male DB-9 serial connector on the other provide a direct plug-and-play bridge between modern computers and serial peripherals including modems, ISDN terminal adapters, barcode scanners, label printers, and industrial equipment that still rely on RS-232 communication. Data transfers at speeds up to 230 Kbps, and the adapter uses no system IRQs, eliminating IRQ conflicts when multiple serial devices are connected to the same PC.
The 1.5-foot length keeps workstation cable runs clean without excess slack, and the compact form factor makes it easy to carry in a laptop bag for field service or on-site configuration work. The Port Authority product line from C2G (a Legrand brand) is built for reliable connectivity across enterprise, retail, and industrial environments where legacy serial equipment remains in active use alongside current-generation computers and tablets running Windows, or Chromebooks with a serial terminal application from the Chrome Web Store.
Where the C2G 26886 USB to DB9 Serial Cable Fits
- IT professionals and field technicians who need to configure network switches, routers, and firewalls with serial console ports where the 1.5-foot USB to DB9 adapter provides a direct console connection from a laptop USB port without carrying a separate serial card or docking station
- Retail and warehouse environments where barcode scanners, receipt printers, or POS terminals use RS-232 serial interfaces where the adapter bridges legacy serial peripherals to modern USB-equipped PCs and tablets without replacing functional hardware
- Industrial and manufacturing settings where PLCs, CNC controllers, or test equipment communicate over RS-232 where IRQ-free operation allows multiple serial adapters on the same PC without resource conflicts that interrupt data acquisition or device programming
