5.Plug one end of the cable into the control module’s remaining communications connector, and plug the other end into a communications connector on the next control module. The photo below shows control modules (RCM, IRCMs, and/or ACMs) connected to an MLC in a typical daisy chain setup.

Connectors are included with each control module, but the cable must be purchased separately. See appendix A for cable part numbers and conductor gauges.

3.Plug the 5-pole connector into one of the control module’s communications connectors.

4.Cut a cable and attach 5-pole connectors to both ends of it for each additional control module that will be connected in a daisy chain. Wire both ends of the cable identically (pin A to pin A, pin B to pin B, etc.). Up to a total of 4 control modules in any combination of models can be daisy chained together and connected to the MLC.

6.Connect the MLC’s rear/bottom panel relay ports to a screen controller or a relay controller (A/C trigger box) if it is appropriate for your installation. Use the following block diagrams as a general reference, and refer to the wiring diagrams that came with the screen.

The MLC contains three relays, so you may install a maximum of one RCM-SC or one RCM-SCLT in a system with an MLC.

Many different brands and models of low voltage controllers can be used with the MLC and RCM to control screen movement. A few examples are given on the following pages, but different models require different wiring.
