2-5-5 For the 2nd generation DC IDU, one or two wired controllers can also support multiple IDUs (a maximum of 16 IDUs). In this case, the wired
controller and IDU need to be connected to the X1, X2, D1 and D2 ports at the same time. There is No polarity between the wired controller and X1,
X2 of IDU, as well as between the wired controller and D1, D2 of IDU. The D1/D2 line sequence between the main and secondary wired controllers
must be consistent. see Fig. 10 and Fig. 11
