## Questions & Answers

**Q: Does this device support node addresses on the rs485 network? seems not, so how do i address a particular device?**
A: Your RS-485 end device has to handle the addressing. This device simple converts RS-232 to RS-485. Any RS-485 devices hanging on the other end have to have their own addressing scheme via the protocol you're using.

**Q: Does it work with modbus ascii rs485 devices?**
A: Yes, this RS-232 to RS-485 adapter works for modbus ascii rs485 devices. If there is any usage issue, please feel free to contact us via the order anytime.

**Q: Does the baud rate auto-detect work if the RS232 side listens only (no transmission)?**
A: Only there is signal transmission between RS232 and RS485, the baud rate will be auto detected.

**Q: Does this do 485 to 232?**
A: Yes, I used this converter for Modbus communication from rs-485 to rs-232.
