3.6.8  ES Option - Emergency Switch Interconnect for –MB systems – BNC 
An optional BNC connector is located on the rear panel for connecting multiple chassis, each 
having a controller and an emergency shut off switch (-ES option).  This connection is required 
to create an OR-ed operation of more than one –ES switch. 
This connector is only present on RS-MB systems with the –ES option.  If present, a suitable 
BNC cable should be used to connect the emergency shut off signal between chassis. This 
connector is labeled as follows: 
"Caution: BNC cable must be connected for system Emergency Shut-Down" 
See figure below for an illustration of a RS180-MB-ES interconnect.
