USB to RS-232 serial adapter with FTDI chip

This USB to RS-232 DB9 serial cable adds one COM port to a computer that lacks a native serial interface. It uses an FTDI controller and includes an extension cable for flexible placement. The adapter installs as a standard Windows COM port and supports Linux and Mac OS 10.x.

Suits users with legacy serial peripherals

Ideal for connecting PDA, digital camera, cell phone or industrial equipment that still relies on RS-232 communication. LED indicators for TxD and RxD aid monitoring. Not for buyers who need more than one serial port or who require galvanic isolation beyond the stated surge protection.

Baud rate up to 921.6K bps with 128 byte FIFO

The high-speed serial port reaches 921.6K bps and supports non-standard rates such as 500.000bps. A 128 byte FIFO buffer sustains throughput under heavy system load. Serial lines carry 10KV surge protection.

Questions about this item

Does the FTDI chip or the DB9 connector on the 765288 cable need periodic replacement?

The FTDI chipset and DB9 connector are solid-state components with no moving parts and no manufacturer-recommended replacement interval.

What limits sustained throughput on this adapter?

The 128-byte FIFO buffer and 921.6 Kbps maximum baud rate set the ceiling for continuous data flow.

How much power does the adapter draw and does it generate noticeable heat during all-day use?

It draws bus power from the USB port with no external supply needed and runs cool enough that the supplier notes no thermal concerns.
