PPI = Point-Point-Interface MPI = Multi-Point-Interface |

Small kick :) Can some one explain the difference on the adapters hardware side? Both they are RS485 and use the same pin-out so what makes it PPI or MPI? |

The only difference between the two is the protocol. The hardware looks the same. BUT the adapters are different. There the processing of RS232 / USB / Ethernet /... from the PC is converted to RS485 but also some data processing and packaging occurs. I doubt someone would be forthcoming with the detail of that. There are adapters that can handle both. But I have had issues that the PPI side got "damaged" but the PPI was still working correctly on "Adapter #1" but its twin "Adapter #2" did not have a problem. That shows there are electronics / processors that are dedicated for PPI and MPI. Why the question? |
