USB to DB9 serial adapter with bracket
This USB to DB9 gender changer converts a USB port into an RS-232 serial connection using a 28.5 cm cable and a bracket that fits a standard PCI slot opening. The assembly also provides a DB25 parallel header for legacy printer or LPT devices. It is built new for installing serial and parallel ports in desktop systems that lack onboard headers.
For adding legacy COM and LPT ports to a desktop PC
Suits technicians and hobbyists who need one serial and one parallel interface through a single bracket. Not for users who require multiple serial ports, pure USB-to-serial conversion without a bracket, or connection to modern high-speed peripherals.

Questions about this item
Will the DB9 connector or bracket need replacement over time?
The DB9 connector and PCI-slot bracket are passive metal parts; only the 28.5 cm cable could wear and require replacement.
What limits continuous data flow through the USB-to-DB9 link?
The RS-232 interface caps sustained throughput at 232 kbps, which is the first bottleneck under heavy use.
