Multi-port USB-RS232 Converters

A multi-port USB-RS232 converter is an ideal way of creating multiple RS232 COM ports in any computer using Windows, Mac or Linux. The created COM ports can be found in Windows Device Manager and can be used as if they were built-in serial COM ports. Each RS232-USB COM port can be used individually or simultaneously.
When creating multiple RS232 COM ports it is very important that you are using a good quality USB-RS232 converter with compatible drivers. If you are using a low-cost USB-RS232 converter you risk problems such as computer freeze, DLL errors or simply difficulties in communicating with the device you connect to the COM ports. Therefore we are usually recommending a USB-RS232 adapter with a FTDI chipset, these USB-RS232 processors has shown to be compatible with most devices and provides easy installation of the USB-RS232 drivers. Other examples of good USB-RS232 chipsets are from Moschip or SilLabs these. Spending a few extra dollars on a USB-RS232 adapter can save you much headache and time. Another important step to successful USB-RS232 communication is proper USB-RS232 driver installation. When installing the USB-RS232 drivers you need to pay attention to the driver installation instructions. If you carefully follow the USB-RS232 installation instructions you will often save time and frustrations, and have your USB-RS232 adapter up and running in a few minutes.
