 Connecting the BLU-CIF to the BSS Audio London Series DSP 
The BLU-CIF ships with two pre-fabricated 12-conductor cables. Each 
cable has 3.5mm connectors on both ends. On one end, the 3.5mm 
connectors are color-coded green and black, so they match up with either the 
Control Port 1 (Black) connector or Logic Inputs (Green) connector on the 
upper right quadrant of the CIF Board.
