Post USB to RS232 TTL Serial Interface Cable (HCCABL0015)

USB to RS232 TTL PL2303HX auto converter module adapter with a 5V output, which provides the most convenient way to connect your RS232 TTL devices to your computer via the USB port. The cable has a built-in TTL COM PC-PL2303HX Chip and uses a standard USB type A male and TTL 4 pin connector. The cable length is approximately 100cm in length.

Black - GND
Green - TXD
White - RXD
Red - VCC (5V)

The interface cable uses the standard prolific drivers.

Windows Drivers: ( ... 25&pcid=41)


Please note the latest version of the Prolific drivers breaks comparability with versions of windows from 8 and above. If you are using one of these version and you are having trouble with the latest version of the driver please download the version below:


To install the driver unzip the folder and right click the ser2pl.inf file and select 'install' from the context menu.

Next open up device manager and plug in the USB cable. Once installed you should see the cable appear as 'Prolific USB-to-Serial Comm Port (COMx)'.

In some cases Windows may automatically install the latest driver instead. If you see a yellow caution symbol beside the entry do the following steps to force windows to install the correct driver:

Right-click the entry in device manager and in the window that opens up select 'Update driver software'.

Click the second option (Browse my computer for software).

In the new windows that opens up select 'Let me pick from a list of device drivers on my computer'

Another window will open. In this windows select the driver version dates 24/09/2008 and then click next.

This should now force the correct driver to install.
