[comp.sys.atari.st] Design for MIDI-to-RS485 translator

jpexg@wheaties.ai.mit.edu (John Purbrick) (01/11/90)

I'm using the MIDI port to communicate with a network (only 2 so far) of
microprocessors (Intel 8031) using RS485 protocol. This is a two-wire-plus-
ground differential line setup using half-duplex mode (ie, the same bus is
used for bidirectional data, hence only one party can transmit at a time).

The circuit for the level translator is available if anyone wants it.
