## Questions & Answers

**Q: Does the usb follow rs232 wiring protocol? i’m hoping this eliminates buying 2 cables: rj12 to 9 pin and a 9 pin to usb with ftdi cable.**
A: Tech answer: Not really. The driver interface of this chip does follow the RS232 Protocol however, the voltage read out is limited to +5V if your device uses true RS232 wiring then this device will not work.  True RS232 wiring has a reversed(voltage shift) voltage that ranges from -15v to +15v (3V min register). In short, unless your device only needs RXD/TXD/GRD within 0 to +5V don't expect it to work.

**Q: Will this cable allow me to connect a headset with mic (Plantronics CO52) to my computer to?**
A: no, it is a usb to  RS232 serial adapter with rj12 interface. It only applies to data communication. Not used for audio transmission.

**Q: the title is labelled as 6p4c is it not 6p6c rj-12?**
A: We confirm that this is the RJ12 interface cable. The RJ12 interface corresponds to a 6-core cable. But we only used 4 touch points of RJ12 interface . So that it can be compatible with 6P4C

**Q: Does this cable create a virtual COM port?**
A: Yes, Built-in FTDI FT232 chip. When you install the driver, a virtual serial COM port is created.
