General

The brake unit is controlled by a BCU-x2 control unit. The BCU-x2 consists of a BCON-12
control board (and a BIOC-01 I/O connector board and power supply board) built in a metal
housing. The control unit is connected to the brake module(s) by fiber optic cables.
In this manual, the name "BCU-x2" represents the control unit types BCU-02 and BCU-12.
These have a different number of power module connections (2 and 7 respectively) but are
otherwise similar.
