1 USB to 3 UART using FT4232H
« on: October 15, 2020, 08:33:40 PM »

Hi,



Please see the attached image.



I have three devices with only UART in all three devices



I need to communicate with all three devices at the same time or one after the other using one USB



I have see USB to UART using FTDI converter . But that is for one to one.



Here one USB to 3 UART I needs to be connect. Is it possible using FT4232H?



I saw one FTDI device FT4232H and the datasheet says "Single chip USB to four channels UART (RS232, RS422 or RS485) or Bit-Bang interfaces. "



can I use this device for my application ?

Hello,

Yes the FT4232H can be utilised to provide up to 4 UART connections from a single USB device, each UART connection would present its own COM port to the host machine.

Can I also please know if RXTX0, RXTX1 and RXTX2 devices can also communicated among themselves via FT4232H as bridge ?

I mean device 0 messages goes through FTDI IC and received by device 1. Also vice versa.

Thanks

Hello,

Unfortunately it is not possible to bridge UART connections through the IC between devices.
