The ethernet control ports should not be connected between an IO box and a console.  It could cause operational issues to the system.  All ethernet traffic is carried via the the AES50. 

The ethernet control ports on IO boxes are for service use, and should only be used by Midas Certified Technicians. 

The port on the console has two uses.  The first, is again for use by a Midas Certified Technician for diagnosing issues, and the second is for a wireless router to be plugged into it for use with the mixtender app.
