The XIt1013 is a 6U VME rear transition module designed specifically to match the XCalibur1931 pinout.
The XIt1013 supports up to six 10/100/1000BASE-T Ethernet ports via six RJ-45 connectors, six serial ports (2x RS-232, 4x RS-232/422/485) via six micro-DB-9 connectors, two PIM sites to route PMC I/O out the rear panel, and four Twinax connectors for MIL-STD-1553.
Due to the limited front panel space, multiple configurations of the XIt1013 are available to handle various I/O access requirements. For example, leftmost PIM site is mutually exclusive with the MIL-STD-1553 connectors. When the XIt1013 is configured for six RJ-45 and six micro-DB-9 connectors, the board utilizes a double-high front panel.
