Description

The PL2303GD is a full-featured single chip USB-CDC to UART bridge controller for connecting a full-duplex UART asynchronous serial interface device to any Universal Serial Bus (USB) capable host. The PL2303GD implements the standard USB CDC Device which is natively supported in most of operating systems; so the PL2303GD does not need any custom driver installation. The operating system or USB host communicates with the PL2303GD through USB CDC application software developed based on Windows/Ma c/Linux DLL libraries provided by Prolific.

USB-CDC device is natively supported in most of operating systems such as Mac OS X 10.7, Linux3.8, Android3.2and their later version. Prolific provides SDK for customers to develop their application software. Refer to instruction of PL2303GDSDK on how to control PL2303GD GPIO using the API in SDK.
