Mezzanine I/O Expansion Board
Multifunction CPU Side Card

Available as a mezzanine add-on expansion board (aka side board) to the SC1-ALLEGRO, SC2-PRESTO and SC3-LARGO CompactPCI® Serial CPU cards, the SCS-TRUMPET provides a variety of frequently required I/O functions available via front panel connectors. Additional interfaces are available as an option via rear I/O. The SCS-TRUMPET can be equipped with an on-board 2.5-inch SATA 6G SSD/HDD, or two M.2 style SATA modules, up to the 2280 format, for miscellaneous mass storage needs.

For dual- or triple-screen applications (in addition to the primary DP video connector(s) on the CPU carrier board), the SCS-TRUMPET front panel is equipped with a DisplayPort connector. Two USB 3.0 jacks allow for attachment of high speed peripheral devices. Audio and legacy signal support is provided in addition. As an option, 6 x USB 3.0 and 4 x SATA 6G (RAID) are available via rear I/O, for use either with a RIO transition module, or secondary CPCI Serial backplane.

The SCS-TRUMPET can accommodate a 2.5-inch SATA drive (SATA docking connector), which is also suitable for a Half-Slim SATA SSD module. In addition, the SCS-TRUMPET can be populated with two M.2 (NGFF) SATA based SSD storage modules, up to the 2280 size.

The SCS-TRUMPET expands the suite of front panel connectors of a particular CPU carrier board by two USB 3.0 receptacles, a DisplayPort video output, 3.5mm Audio In/Out jacks, and a D-Sub EIA-232 COM port connector. Alternatively, a second COM port connector or up to three additional USB 2.0 jacks are available on request.

The SCS-TRUMPET is a mezzanine side card, to be fixed on top of a suitable CPU carrier board. The pitch between carrier PCB and mezzanine PCB is 4HP, resulting in a 8HP common front panel for the entire assembly. Up to four mezzanine inter-board connectors are in use, for distribution of legacy and high speed I/O signals from the CPU carrier to the side board. These are referred to as HSE (SATA & USB 2.0 High Speed Expansion), EXP (Legacy Expansion), PCIE (PCI Express® x 4), and DP (DisplayPort). The mezzanine connectors are situated on the bottom side of the SCS-TRUMPET, facing towards their mating CPU card connectors.

The SCS-TRUMPET also is a carrier board itself, which can accommodate two M.2 SATA SSD storage modules, or a 2.5-inch SATA drive, and a front panel I/O expansion card as an option.
It is recommended to use a CompactPCI® Serial backplane which provides the CPU card system slot on the right edge, in order to prevent loss of a peripheral slot (the SCS-TRUMPET is then positioned out of the backplane shape). Use of the rear I/O option requires either a custom specific rear transition module in addition, or a secondary CPCI Serial backplane, for front installed SATA or USB based CPCI Serial cards.
