This cable has two IDC sockets and one IDC plug. Connect the plug to the third MG socket, and you’ll be able to link two more groups to a master. The group-to-group sockets are spaced to accept group configurations of roughly 72 HP, allowing up to 4 QSCs.

It is possible to chain more GG extensions to one another, such as adding a fourth group or connecting groups with larger channel configurations (up to eight QSCs).

It is not possible to connect the channel directly to a master module without a group between them.
