## Questions & Answers

**Q: I installed dt-9011 rs232 but cannot find the driver for Windows 10. Where can I download the driver?**
A: For the RS232 serial isolator itself, there is no need of driver, if you use the isolator with other serial adapter like USB to serial adapter, you may find the driver from the supplier of the USB to serial adapter. And if you purchased USB to serial adapter from us, pls contact us directly via the order page "contact seller", so we can tell which driver you need.

**Q: Will this work for a usb/serial line from my macmini to my transciever (i.e., is there sufficient power to get the signals accross)?**
A: Yes, this RS232 serial port isolator can be connected with a usb to serial cord, but please make sure that serial port pin of the cable is a standard 9 pin to get sufficient power or you may add a DC 9V power supply to pin 7.

**Q: Would this work for a ROC809?**
A: As long as your device is with RS232 port, it will work. If have any further question, please feel free to contact us via the order page directly anytime.
