VXI Embedded Controllers

The choice of VXI embedded vs. external controller depends on your performance, space, flexibility, and cost needs (see chart below). For best performance in a compact space, choose a VXI embedded controller. Since the embedded controller is in direct physical contact with the VXI backplane, youll get optimum response time.

		Embedded			External

Speed		Very fast.*			Speed depends on the interface.*
						HP-IB=medium speed, MXI or VXLink=higher speed
Configuration	Limited configurations. 	Virtually unlimited configurations. Controller
Flexibility	Powered by the VXI mainframe's	power supply is unaffected by power loss to  
		power supply			VXI mainframe.
Number of 	1 to 3 slots. No command	1-slot for command module, EISA/ISA-to-MXIbus  
Slots Used	module required			Interface,or VXLink card.

Cost		Usually more expensive.		Usually less expensive.

* Register-based or message-based cards with binary data transfer must be used for
 maximum speed improvement.
