Auto-Zone CV & CV-EX
Section 2
Installation and Wiring 2-7
Even though the daisy-chain configuration is preferred, the star configuration can also be
used for the CV or CV-EX systems. If required, a combination of the two can also be
used. Remember, the best communications loop wiring scheme is the one that utilizes the
minimum number of ends while using the shortest wiring path.
Note:
The communication loops do not have to follow the controller or MiniLink
address sequence.
Caution:
If the communications loop is not installed in conduit, be careful to
position the cable away from high noise devices like fluorescent lights,
transformers, variable frequency drives, radio or TV transmitting
equipment, furnace ignition system wires, etc. Conduit is not required
for communication loop wiring unless required by local codes.
