Questions about this item

How fast can the 920 kbit/s rating move data in a real setup?

The 920 kbit/s ceiling is the serial link limit; actual throughput depends on the USB host controller and the connected RS232 device.

What does the USB-to-RS232 interface cap in practice?

The USB side handles enumeration and power, while the DB9 side is limited to 920 kbit/s RS232 signalling.

What clearance does the 1 ft cable and DB9 connector need to fit?

The 1 ft length and standard DB9 plug require only a free USB-A port and a matching serial port on the target device.
