 ====== Board "Rahmenplsback" ======
 This board acepts 1pol lemo cables carrying "Rahmenpulse" from feet throughs at the back of the cassis and concentrates the signals to four female VG connectors. Those connectors pass the signals via adapter bords "AMP68VG96" and NI-cable "SHC68-68-EP" to the NI PXI-7811R FPGA-board:

-There is one mistake in the skematic that should not take effect because of the later outside made connections: As can be seen in the middle of first coloum at  connector P1C2A: There the GND connection for the connectors J13, J15, J18, J19, J21 and J24 is missing. Supposing target system for this would work with different reference levels it would not be able to see the signals although they are correctly feet. But because the feet throughs of chassis back are not isolated for screens of incoming Lemo connections all this screens are tied together and this way as well internal then although extrernally about the chassis referenced to ground (GND). The mistake does not take effect.
