MXI-2 System Expansion, PXI Remote Control Module—The PXI-8320 is a 3U, 32-bit, CompactPCI compatible plug-in circuit module that fits into one of the peripheral slots of a PXI or CompactPCI chassis. This module allows a PXI/CompactPCI computer to be directly connected to an MXIbus system and vice versa. Because the PXI-8320 relies on the same set of communications registers as other message-based VXIbus systems, MXIbus systems consider the PXI-8320 module to be a VXIbus device. The PXI-8320 can also be used as an MXIbus system controller and can route MXIbus signals directly to the PXI-8320. Additionally, up to 16 MB of dynamic RAM can be added to the PXI-8320, which the module can either share with MXIbus and VXI / VMEbus, or use as a buffer.
