Other Parts Discussed in Thread: ISO1176, , ISO3082, ISO1410
Hello,
Will below block diagram work? I needed to connect the Slave PSU's using RS485 to the Master MCU, but it both PSU's/Slaves and MCU/Master need to be isolated from each other.
I'm already communicating with one of TI's FA but unfortunately he is on leave today and was advise to check in this forum. I needed an answer as soon as possible so I can start working on the finalizing my schematics. Let me know if there are other options to achieve fully isolated master/slave configuration.
Note: I needed to use HV opto in this case as part of the requirement.
Below are some questions:
- Will there be any issue using below RS485 repeater combination?
- Do I still need to control RE/DE separately from the our ECAT/MCU board?
- Or I can just enable both RE and DE permanently since the ECAT/MCU board is already aware that it in receive or transmit mode?
- We prefer not to have another RE/DE control for cost reduction purposes but wanted to confirm if there will be any complications in taking this it out.
