SDCS-DSL Board
The SDCS-DSL board provides a drive to drive communication. The communication hardware and
protocol is based on CAN bus.
This communication will be used for 12-pulse operation, communication to field exciter either single
phase or three phase field exciter.
The communication hardware is equipped with an isolated supply and isolated transmitter. The
terminator can be set by Jumper S2 and S1selection of termination see section DCS Link Wiring
