The dipswitch Master-Slave tells the unit if it is used as master or slave.
When it is used as the master, it responds to the DC-bus voltage. When it is used as
the slave, it responds to slave input (S1-S2) which has to be connected to the masters
M1-M2 output.
In case only one brake unit is used, leave it at Master position, which is the factory
setting.
