The XIt1048 is a 6U VPX Rear Transition Module (RTM), which supports I/O breakout from select X-ES 6U VPX single board computers. When installed in an RTM slot of an appropriate 6U VPX backplane, the XIt1048 routes I/O signals from an associated SBC’s rear panel P1 and P3-P6 connectors through the VPX backplane to connectors on the XIt1048 to allow connection of these signals to external equipment.
The XIt1048 routes four 10/100/1000BASE-T Ethernet ports to RJ-45 connectors; one USB 3.0 interface to two USB Type A connectors; four SATA interfaces to two mSATA ports, a SFF-8644 mini-SAS connector, and one optional eSATA port; and four serial interfaces available as two RS-232/422/485 and two RS-232 to two micro-DB-9 connectors. Default configuration supports RS-232 from RP6 to the front panel, with an optional hardware configuration to alternatively support RS-232 from RP2 to the front panel. An optional configuration is also available to route a USB 2.0 interface from RP6 to a line-level audio jack; in this configuration, the front panel eSATA port is unavailable.
A dataplane breakout site connects two x4 Fat Pipes from the P1 connector to breakout modules that convert the signals to standard connectors. This facilitates rapid prototyping of complex system topologies using standard, off-the-shelf equipment.
