Multiple Controller INstallation

Linking Multiple Controllers

The RNET Link In and Link Out can be used to connect two or more (up to 6) MCA-C5 controllers (does not support CAV6.6, CAM6.6 or CAA66 controllers). The connection is made using a CAT-5e patch cable from the Link Out of the first controller and into the Link In of the next controller. Along with RNET data signals, the RNET Link In and Link Out port passes source IR signals.

The CAT-5e patch cable must have an RJ-45 connector on each end with T568A wiring configuration. It can not exceed 18 inches (45.7 cm) in length to avoid potential cross-talk between the source-specific IR repeating signal lines.

Controller ID Switch Settings

The Controller ID switch is a rotary switch with seven positions. It is used to set the controller ID number for multi-controller systems, and to put the MCA-C5 into Firmware Update mode.

If two or more MCA-C5 controllers are connected using the RNET Link In and Link Out ports, each controller must have a unique controller ID prior to being connected through the RNET ports. Set each controller’s ID switch to a unique number. Any multi-controller configuration requires that one controller be set to controller ID #1. This action must be performed before the system setup procedure is completed through SCS-C5 software and before powering up the system. The small arrow on the dial should point at the desired setting.
