===== Bus Connection Cable =====

{{hiq_components:cad-px.jpg?300|}}

  * The product includes a 2.5 cm RJ9-to-RJ9 bus cable (Order code: CAD-P0) for connection to controllers, allowing the units to be linked together.
  * Longer cable versions are available under order codes CAD-Px.

===== CAD-BC Bus Coupler =====

MC-24-H1 is used together with the **CAD-BC bus coupler**, which provides the connection between the controller and the bus connection cable.  
The CAD-BC is mounted on a DIN rail and provides an RJ9 bus interface for linking the controller with other units in the system.  
The **CRD**, **TGP**, and **FC** modules are connected to the **CAD-BC** in parallel, in accordance with the relevant wiring diagram.
