Each fibre optic cable has a number 1...8 and 11...18 marked on the cable shield at both cable ends.
Connect each cable to the connectors marked with the same number on the ASIC board and on the
rear side of the control unit. Additionally, you may have to connect the 4 fibre cables from the feed-
back board to the star coupler board. The list of the optic signals can be found in Figure 59.
