The same type and quantity of connectors and DIP switches shown above can be found on the rear panels of all models of the control modules.
1 Communications connectors — Use these connectors to connect |
control modules together and to connect them to the MLC and |
to an optional IR Link infrared repeater. Both connectors |
function the same way, so they are interchangeable. |
Plug one end of an Extron |
Cabling
For each control module to be connected to an MLC, set the rear panel DIP switches, then follow these steps:
1.If it hasn’t already been done when the wall box was installed, cut a length of Extron
2.Using the following diagram as a guide, attach a 3.5 mm,
Wire both ends of the cable identically (pin A to pin A, pin B to pin B, etc.).

into a connector on another control module or an IR Link, or |
connect those wires to the direct insertion IR/RCM captive screw |
connector of an MLC. Do not install more than one IR Link. |
2 DIP switches — Set these switches to identify the address of |
each module. Each module must have a unique address. Note |
the direction of the arrow on the switch. |

DIP switch settings
Only three wires are required, but use four wires (A, B, C, D) if an IR Link infrared repeater will be daisy chained with the control modules. Refer to the IR Link User’s Manual for details.
Do not install more than one IR Link in a MediaLink system. Also, do not connect more than four control modules (RCMs, ACMs, IRCMs) at a time to an MLC.
The MLC contains three relays, so you may install a maximum of one
