Page 7: Introduction
Re-Driver circuitry to a PCI Express External Cable Interface Connector on the front panel. The MAMC-XLINK is member of a family of XLINK boards which enable the connection of different system platforms via a PCI Express External Cable Interface. Typically one system will be a master system containing a processor card and the second system will be a slave system which does not contain a processor card and is controlled by the master system. -
