MiniLink Interface
The MiniLink Interface is only required and used with the CV-EX system. It is not
required for the CV system. It functions as the loop master for each CV-EX system local
loop. With the CV-EX system, each local loop of CV controllers (maximum of 30) is
connected to a MiniLink. Two MiniLinks are supplied with the standard CV-EX system.
This allows up to 60 CV controllers (30 maximum per local loop) to be tied together to
form an integrated system. A CV-EX expansion kit is available which provides another
MiniLink to allow an additional 30 CV controllers to be connected to the system. A
maximum of two expansion kits can be used on the CV-EX system to provide integration
of up to 120 CV controllers. See Figure 2-18 for an overview of the MiniLink.
