Computer Sense CS:
Along with the computer control mode of operation, a computer verification
method is also incorporated into the system. A 40 pin vertical terminal block on the back panel
allows the computer to verify the actions initiated by the computer. This is done through a set of
normally open dry contacts that are associated with each particular function.
