Vanguard Managed Solutions 7300 Series CompactPCI Connectors, Bus Type Connector Purpose

				Vanguard 7300 Platform Version 2
	CompactPCI Connectors
Description
		The CompactPCI midplane is located toward the middle of the chassis, and each card
		slot is equipped with male J1 connectors (pins). The plug-in cards use socket
		(female) connectors. The same type of connectors are used on the rear side of the
		midplane to accept rear I/O transition modules. Midplane connectors have external
		metal shields for proper shielding and grounding in noisy environments. Controlled
		impedance minimizes unwanted signal reflections.
		Figure 1-13shows the standard five CompactPCI card connectors that make up the
		CompactPCI bus interface and the user input/output sub-bus. The following table
		summarizes the function of the standard card connectors:
		Bus Type	Connector	Purpose
