RS-485

Is a half duplex serial communications link and is the

standard most commonly used for industrial applications due
to it's high noise immunity and multi-drop capability. It
enables a PC to communicate with up to 32 instruments
over distances up to 1200 metres, and requires the addition
of an RS-485 interface card, or a separate RS-232/485
converter.
