How do I connect a serial RS232 device?

To connect a serial / RS232 device to your computer which doesn't have a serial port, you will normally need a USB to Serial adapter. All the adapters that we supply (branded and OEM) have been tried and tested by our engineers and offer excellent OS support from Linux, MAC OS and Windows 7 / Windows 10. See the tips below to find a suitable device. The FTDI chipset based devices feature "COM Port Retention" so you can be confident of the COM port number not changing when you unplug and plug back into different USB ports.

Avoid frustration and time waste installing devices with unknown chipsets. Most of our USB to serial devices feature COM retention - look for FTDI chipset in the description.  Some suppliers may charge an extraordinary amount for "COM retention" devices as if it is extremely expensive - it isn't!
