USB to RS232 Serial Adapter with FTDI Chipset

This USB 2.0 to DB9 serial cable converts a USB port into a standard RS232 COM port for legacy equipment. The six-foot cable length provides reach for industrial or laboratory setups. It targets technicians and engineers who need reliable serial connectivity on modern Windows or Mac computers.

FTDI Chipset and Driver Support

The industry-standard FTDI chipset ensures broad compatibility with Windows 10, 8.1, 8, 7, Vista, XP, 2000, Linux 2.4 or above, and Mac OS X 10.6 and above. Drivers must be downloaded from the official FTDI website before use. The gold-plated USB connector resists corrosion for a stable connection.

Suits DB9 Equipment, Not VGA or Male Ports

This adapter suits users connecting modems, CNC controllers, POS printers, PLCs, or PDAs that have a female DB9 serial port. It is not a VGA monitor cable and does not fit 15-pin connectors. Buyers needing a male DB9 plug or a video display adapter should look elsewhere.

Questions about this item

Will the FTDI chipset need firmware updates or driver reinstallation later?

The adapter uses the FTDI FT232 chipset; drivers are downloaded from the FTDI or Cisco website and installed once. No firmware updates are required for the chipset itself.

What is the maximum sustained data rate before the USB 2.0 link becomes the bottleneck?

The USB 2.0 interface limits sustained throughput to 1 Mbps, which is the first limit reached under continuous serial traffic.

Does the cable draw enough power to heat up or need active cooling when used all day?

The adapter is bus-powered from the USB 2.0 port and runs cool during continuous operation; no fan or external power supply is needed.
