TeKit USB 2.0 to RS232 DB9 Serial Adapter

This TeKit adapter cable connects a standard USB 2.0 port to a DB9 serial interface. It is designed for users who need to link legacy RS232 equipment such as label printers, scanners, modems, PDAs or digital cameras to a modern computer. The male-to-male connectors provide a direct link without extra gender changers. The one metre length suits typical desktop or bench setups.

USB 2.0 interface limits transfer to 1.1

The cable complies with USB specification revisions 1.1 and 2.0, so the practical throughput ceiling is the 2.0 bulk endpoint rate. The integrated PL2303 chipset supports over 1 Mbps serial data transfer, but actual speed will be bounded by the host controller and the attached device's own UART capability. Shielded construction helps maintain signal integrity over the full cable run.

PL2303 chipset determines driver compatibility

The single specification that decides fit is the PL2303 bridge controller, which requires a matching driver for the target operating system. The supplier lists support for Windows 98, SE, ME, 2000 and XP; newer Windows releases may need a separate driver download. Buyers whose OS lacks a signed PL2303 driver will find the adapter non-functional.

Questions about this item

Is the 1 metre length the only option for this TeKit USB 2.0 to RS232 DB9 cable?

The adapter cable is supplied in a 1 metre (100 cm) black version with male-to-male connectors.

What does the "over 1 Mbps" transfer rate mean when I connect a serial printer or scanner?

The PL2303 chipset supports data rates above 1 Mbps, so typical RS232 peripherals such as label printers, scanners or modems operate at their full rated speed without bottleneck.

Which USB standard does the connector use and what does that limit in practice?

The cable uses a USB 2.0 male plug that is also compliant with USB 1.1, so it will work on any standard USB port while the RS232 DB9 side handles the serial signalling.
