FMC-Video includes two status 2 LEDs, placed on the back of the board. These LEDs
indicate that the board is being powered correctly and the software has initialized it,
respectively. See
Table 2-7: Board LEDs
Wherever possible this module conforms to VITA-57 from a mechanical standpoint. It is
impossible to meet the mechanical specs due to the size of the connectors that must be on
the board. For instance, all the connectors cannot fit within the I/O envelope height of
9.5 mm on the front of the board. Due to this, some connectors must be put on the back of
the board. However, the orientation of these connectors should still support two FMC
modules installed side by side on a carrier. To this end, all connectors are oriented toward
the front panel side of the board or directly vertical.
Although the mechanical spec is broken by this design, it is possible for mechanical
conformance to be achieved by simply removing the connectors that are placed on the
back.
Rule 25 of the VITA-57 spec requires a minimum of 500 VDC and 1 MÙ of isolation. The
only S-video connectors available for this application are rated at 250 VDC isolation and,
therefore, violate this rule. Even with these connectors removed, there is still only 250 VDC
isolation, because the spacing between pads on the PCB artwork to accommodate this
connector.
