CV-EX System
See Figure 4-2. The CV-EX system has two types of communications loops. The loops
which the CV controllers are connected to are called the Local Loops. The MiniLink is
always the loop master on the CV-EX local loop. You must be sure the MiniLink is
connected, powered up, and functioning if you are troubleshooting a Local communica-
tions loop. The other type of loop on the CV-EX system is called the Network Loop. This
loop connects all the MiniLinks together and then ties into the CommLink IV which is
the Network Loop Master. The CommLink IV jumper switch must be set for multiple
loop operation when used with the CV-EX system. See Figure 4-4 for the correct jumper
switch setting.
