Among these ID values, only ID1-ID5 are valid. The bits from high to low are ID5-ID1. The value of the DIP
switches is a binary value 0 or 1. When the DIP switch is toggled to ON, the value is set to 0 by default. The value
0 indicates a master subrack, and other values indicate slave subracks.
For details on the principle for configuring the master and slave subracks, see "Master-Slave Subrack" in the
Feature Description.
