As soon as they received bus data they would repeat it over the fibre. When they received fibre data they would enable the bus transmit for a period equal to a tiny portion less than a complete ASYNCH protocol word and then wait for the next activity ready to change direction at the end of each byte. Yes there were DIP switches. | |

| Aug 18, 2017 at 10:19 | comment | added | PeterJ | You normally don't use hardware flow control with RS485 so that should be fine. But how do you know it's not sending / receiving? Are you looking at the lines with an oscilloscope, or is it just because the other device isn't responding? But you need some more details on all that in your question. | |
| Aug 18, 2017 at 10:18 | comment | added | DiBosco | Do you mean flow control or direction control? Flow control can be done in software or hardware. You seem to be very confused in general here and a lot of your question makes no sense. We need a schematic of how your system is set up and what you mean by flow control which I suspect is direction control. | |
