This technology has inspired the development of [protocol](/source/Protocol_(computing)) [Profibus](/source/Profibus). The MPI is based on the [standard](/source/Technical_standard) [EIA-485](/source/EIA-485) (formerly RS-485) and works with a speed from 187.5 [kBd](/source/Baud) to 12 MBd. The [network](/source/computer_network) MPI must have [resistance](/source/resistor) at the end of the line and it is generally included in the [connector](/source/electrical_connector) and activated by a simple switch. Manufacturers using MPI technology offer a range of connections to a PC: MPI cards, [PCMCIA](/source/Personal_Computer_Memory_Card_International_Association) cards, [USB](/source/Universal_Serial_Bus) adapters or [Ethernet](/source/Ethernet). ==References== {{reflist}} Category:Industrial computing Category:Programmable logic controllers Category:Serial buses --- Adapted from the Wikipedia article [Multi-Point Interface](https://en.wikipedia.org/wiki/Multi-Point_Interface) by Wikipedia contributors ([contributor history](https://en.wikipedia.org/wiki/Multi-Point_Interface?action=history)).
