RS232 vs RS485 in a Vehicle: Which Serial Port for Which Peripheral
RS232 and RS485 both turn up on the same vehicle-terminal spec sheet, and integrators routinely wire the wrong one. The choice is not about speed or age. It comes down to two questions: how many devices are on the line, and how far does the cable run...
