Control Chain is an open standard developed by MOD Devices that defines communication protocol, electrical specification, cables and connectors. It's used to interconnect external controllers (a.k.a peripheral devices) as expression pedals and foot-switches extension to MOD devices, for example the MOD Duo.

The external controllers are connected to the MOD using a regular Ethernet patch cable and they have two connectors, what allows a next external controller to be connected, creating then a chain. The MOD will provide power supply to the controller via the patch cable.

Control Chain support is available only from version 1.4

How to use Control Chain devices

The external controllers are connected using an Ethernet patch cable coming from the MOD Control Chain port to the Main port of the controller. To connect the next controller the cable should connect the Next port of the previous controller to the Main port of the next controller.

Once the controller is connected it will be automatically detected and ready to use. The actuators of each Control Chain device will show up as option to be mapped in the plugin configuration screen. See accessing plugin configuration screen for details.
