6 BCU-01/11 control units
the SDHC memory card inserted into the SD CARD slot and can be analyzed by ABB
service personnel.
The drive-to-drive link (XD2D) is a daisy-chained RS-485 transmission line that allows
basic master/follower communication with one master and multiple followers. The
control unit has also one option slot for connecting the RDCO DDCS communication
option board. For more information, see the appropriate hardware manual.

Fiber optic connections
BCU-01 control unit has two fiber optic connections for converter modules,
V1 and V2. BCU-11 control unit has a BPEB-05 board that provides five additional
fiber optic connections. Thus, BCU-11 has seven connections (V1…V7) in all.
The maximum lengths of the cables are:
•
1 mm plastic optical fiber cables, 35 m (115 ft)
•
200 μ m hard-clad silica fiber cables, 100 m (328 ft).
Fiber optic pairs connected to one control unit must have the same length. With long
distances, cables of different length cause different delays, which can have an
unwanted effect on the operation.
For instructions on connecting the control unit to the converter module, see the
appropriate hardware manual .
