Installing the CommLink IV
When you are using the CommLink IV with the Auto-Zone CV or CV-EX System and
are not going to use a Computer, Remote Link II, or IP Module, you only need to perform
three steps to install your CommLink IV.
Step #1: Check and make sure your CommLink’s communication switch is set to
Multiple if using the CV-EX system. See Figure 2-13 for details on setting the DIP
Switch on the CommLink IV.
Step #2: Install communications wiring (18-gauge minimum, 2-conductor twisted pair
with shield) from the CommLink IV to a CV Controller (CV system) or MiniLink (CV-
EX system).
For the CV system, the communication wiring should connect from the T, G, & R
terminals on the CommLink IV to the T, SHLD, & R terminals on the CV Controller. See
Figure 2-14. Be sure that you wire the CommLink “T” terminal to the CV Controller
“T” terminal, The CommLink “G” Terminal to the CV Controller “SHLD” terminal, and
the CommLink “R” terminal to the CV Controller “R” terminal as shown.
For the CV-EX system, the communication wiring should connect from the T, G, & R
terminals on the CommLink IV to the network T, SH, & R terminals on the MiniLink.
See Figure 2-15. Be sure that you wire the CommLink “T” terminal to the MiniLink “T”
terminal, The CommLink “G” Terminal to the MiniLink “SH” terminal, and the
CommLink “R” terminal to the MiniLink “R” terminal as shown.
Step #3: Wire the supplied 120/24 VAC power pack to the 24 VAC and GND
terminals on the CommLink IV. Plug the power pack into a standard 120 VAC duplex
outlet.
If you intend to use a Computer, Remote Link II, or IP Module in addition to the steps
just performed, you will need to perform additional installation procedures. Please refer
to the CommLink IV Technical Guide—WM-CLIV-TGD which is supplied with the
CommLink IV. It will instruct you regarding installation and troubleshooting of the
CommLink when an optional personal computer and/or other communication devices are
used. This manual is also available from any of the WattMaster websites for downloading
as are the USB drivers and Prism Software. These are required for installation when using
the optional personal computer or other communication devices.
