Issue Details

I have a TriSonica Mini sensor that uses serial communication, and I'd like to use it with a USB 232/4 device. My sensor has four wires RXD, TXD, GND, and +. How should I wire this?

Solution

The RXD, TXD, GND pins will all correspond with certain pins on your RS 232 device. The plus wire indicates an excitation voltage that will need to be supplied externally to work with your USB 232/4 device.
