Control cable connection of dual bus system consisting of two parallel systems

For the dual bus system consisting of two parallel systems respectively composed of two or more single units, you must form a ring connection between the two parallel systems with the optional 9-core LBS cables. The connection interfaces are the X4 sockets on the parallel boards, as shown in Figure 7-6.
