Generic Interface
The term "generic" means that this port is not dedicated to any specific physical
interface. This port is connected to an external communication interface board.
The signals are connected to the opto couplers on the external communication
interface board. The primary use of this channel is for the Mikohn Link Progressive
display, which is connected through an interface communications inlet board. The
Generic signals are shown below.
