Which USB-RS232 cable adapter should I use?

For computers that do not have (enough) serial ports, we offer the MultiCOM device (6× RS232 to USB converter). MultiCOM is particularly suitable if you need to connect several devices at once.  Ensure you have a USB port in your computer to accommodate the MultiCOM.

There are also other USB-RS232 cable adapters available on the market. However, please note that some chipsets have known compatibility issues (in particular, converters based on processor chips provided by Prolific).
