LEMO
Bidirectional LEMO connector block. Each connector (or connector pair) gets an IN pad, an OUT pad and a DIR pad that selects the direction at run time: DIR = 0 makes the connector an output, DIR = 1 an input. The block has two shapes - a 3-row pair variant on DT5550 / DT5550W and a 2-row single-connector variant on the other boards that expose LEMO pins.
