CommLink IV Technical Guide

Operator Interface
CommLink IV Overview
The CommLink IV is used to transfer communications between
controllers on your control system loops. It can also be used as
an interface for connection of a computer to your system.
The CommLink IV provides communication with the control
system through any computer that is running Prism software.
For remote communications, an IP Module Kit can be installed
for LAN and Internet connections or a Remote Link II can be
connected for dial-up connections.
Optional IP Module Kit
The OE415-02 IP Module Kit, when installed and confi gured
in the CommLink IV communication interface, provides TCP/
IP Internet and/or intranet connection for Ethernet networked
computer systems allowing them to communicate with your
control system. The OE415-02 IP Module Kit consists of the IP
Module and a 10 ft. long CAT5 Ethernet crossover cable.
Using standard TCP/IP Protocol, with WattMaster’s Prism
software, you are able to monitor and confi gure your controllers
without a modem or a direct connection from a PC. Utilizing
existing routers, proxies, or fi rewalls allows a PC running Prism
to connect to a controller in a remote accessible location or
building. Several IP connection profi les can be created to facilitate
monitoring several CommLink IVs with IP Module Kits installed
on individual sites.
Optional Remote Link II
The OE419-06 Remote Link II is a 14,400 baud modem that can
be used with a CommLink IV or a computer. It is used to provide
remote dial-up communications with the CommLink IV. When it
is used as a computer modem (at the remote computer location),
it connects to the remote computer.
NOTE:
WattMaster will not support any other internal or
external modems by other manufacturers.
The Remote Link connects to the CommLink IV communications
interface at the control system location via a DB9 serial cable.
A telephone line connects the Remote Link to the local phone
service. Using another Remote Link modem connected to a
computer and phone service at a remote location, you can moni-
tor and control the system using the Prism computer front end
software. Connection is made by dialing the telephone number
of the job site where the Remote Link is located.
Installing CommLink IV ONLY
When you are using the CommLink IV in an application without
a computer, Remote Link II, or IP Module, follow Steps 1 & 2
in the Quick Guide on page 4.
