USB-RS232 Interface

The USB to RS232 adapter is designed to make serial port expansion quick and simple. Connecting to a USB port on your computer or USB hub, the USB to RS232 adapter instantly add serial communication ports to your system. By taking advantage of the USB bus, the USB to RS232 adapter makes it easier than ever to add serial ports and serial devices to your system with easy plug-and-play and hot-plug features.

Plugging the device to the USB port, the adapter is automatically detected. There are no IRQ & COM port conflicts since the port doesn‘t require any additional IRQ, DMA, or memory as resources on the system. Thereby, the USB to RS232 adapter works perfectly with KEIL µVision3.
