1 USB to 3 UART using FT4232H
vikash23:
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 ?
FTDI Community:
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.

Hi,
Thanks for your response.
If the UART bridge is not possible, can I please know the best method to communicate between device 0 and device 1 ?
Any PC self developed application can receive the data from both devices via FTDI and do a bypass on the PC application ?
Regards,
Vikash
