Multiplex (MUX) Controls

A multiplex system is one by which multiple analog message signals or digital data streams are combined into one signal over twisted pair, or fiber-optic, cables. These multiple messages contain signals to open or close valves, modify regulator pressures, extend or retract cylinders and transmit pressures, temperatures and position information etc., back to surface.
