Does this device support node addresses on the rs485 network? seems not, so how do i address a particular device?

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.

Does it work with modbus ascii rs485 devices?

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.

Does the baud rate auto-detect work if the RS232 side listens only (no transmission)?

Only there is signal transmission between RS232 and RS485, the baud rate will be auto detected.

Does this do 485 to 232?

Yes, I used this converter for Modbus communication from rs-485 to rs-232.
