For using THVD1450, if we choose hardware control and baud rate is 9600.

Could we connect with 32 device?

Thanks

Yes. Any RS-485 driver can handle 32 unit loads. Many receivers (including the THVD1450 itself) load the bus less than one unit load, so you can have even more.

Hi Jiaxin,

Yes that is okay - the THVD1450 can handle any data rate up to 50Mbps as well as support up to 256 transceivers on the line - so 9600bps with 32 transceivers is okay.

Please let me know if you have any other questions!

Best,
