## Questions & Answers

**Q: will this connector work for my royal cash register? I have bought scanners for the register, but wonder if the USB scanners may last longer.**
A: This is a serial to USB converter, not vice-versa. If your scanner has a USB connection already, then this item is of no use to you. By the way, less and less laptops (and I would assume desktops) come equipped with a COM port (that is why I needed this converter), so opting your USB port for a COM port sounds more of an own goal. Perhaps I misunderstood your question.

**Q: is it prolific**
A: Prolific chips often exhibits erratic behavior with some serial devices.  The reliable chip is the FTDI chip.

**Q: Will this work to connect a computer to a CISCO Switch via the console cable?**
A: Yesssss its a great usb to serial cable

**Q: I assume this will plug and play with WIN10 64x ...? thanks!**
A: It is just a cable so I would assume so.  My husband uses it with his Windows 10 laptop to connect to his telescope.
