USB to RS232 TTL UART converter cable

This cable connects a USB port to a serial RS232 or TTL UART interface using the PL2303HX chipset. It provides a simple way to add a COM port to modern computers that lack native serial connectors. The adapter suits engineers, hobbyists and technicians working with legacy industrial equipment, microcontrollers or networking gear.

Practical limits of the USB to serial interface

The PL2303HX chipset handles the USB to RS232 TTL UART conversion automatically without external power. Data rates and voltage levels depend on the connected serial device and the host USB port capabilities. The cable does not isolate signals, so ground loops or voltage mismatches between the host and target equipment can cause communication errors or hardware damage.

Questions about this item

Should I pick the RS232 or the TTL UART version of this cable?

The cable carries both RS232 and TTL UART signals on the same PL2303HX converter, so one unit covers both interfaces.

What does the 2303 in PL2303HX mean for my device?

It identifies the Prolific bridge chip that handles USB-to-serial conversion at up to 232 kbaud.
