CommLink IV Technical Guide
General Information
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.
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.
System Requirements
To program the CommLink IV to work with Prism, you will need:
Standard Items (Required)
• CommLink IV with USB cable and power adapter
• A PC with an Ethernet communications port or USB
port (supplied by others)
• USB drivers on CD-ROM (supplied and also downloadable
from any of our websites)
• Microsoft Windows® XP, Vista or 7
(must be installed on the PC you are going to use)
• Prism software (can be downloaded from any of our
websites)
Optional Items
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 monitor 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.
• CommLink IP Module that comes with Ethernet RJ-45
Crossover CAT 5, 10 ft. long cable for LAN, and Internet
remote communications
• Remote Link II that comes with connection cables for
dial up remote communications

Quick Guide
Quick Guide
Follow the fi ve steps below to get your CommLink up and running in
no time.
NOTE: If you are using the CommLink IV without utilizing
Prism, you need only perform Steps 1 & 2.
Step 1: Set your CommLink’s communication switch to Multiple
or Single. See Figure 2 on page 6.
Step 2: Wire your CommLink to the appropriate controller on your
system, and plug the CommLink into a power supply. See
Figure 1 on page 5.
Step 3: Windows XP users, attach one end of the USB cable to the
back of your CommLink and the other end into your com puter’s USB port. Then follow the instructions that appear
on your screen to install the USB drivers located on the
included CD-ROM.
Windows Vista and 7 users, install the USB drivers located
on the included CD-ROM. Then attach one end of the
USB cable to the back of your CommLink and the other
end into your computer’s USB port.
IMPORTANT NOTES:
Make sure you follow the appropriate directions for
your Windows version - Windows XP directions are
different from Windows Vista & 7.
For Windows XP, fi rst plug in your CommLink device,
then follow the instructions to install the USB drivers.
For Windows Vista or 7, fi rst install the USB drivers,
then follow the included CommLink IV connection and
wiring instructions sheet (Figure 1 on page 5) to connect
and confi gure the CommLink IV.
Make sure you follow the appropriate directions for
your Prism version - Prism directions are different
from Prism II.
Familiarize yourself with all system components and
review all documentation. Pay special attention to
“Cautions,” “Notes,” and “Warnings” since these may
keep you from experiencing unnecessary problems.
If you encounter any problems, please refer to the
Troubleshooting section of this guide fi rst. If you
can’t resolve the problem, please call WattMaster
Technical Support at our toll free number—
1-866-918-1100.
Step 4: Install Prism software on your computer.
NOTE: For remote communications, follow the instructions
included in your IP Module Technical Guide or Remote
Link II Technical Guide.

Connecting the Network
Proxy and Firewall Compatibility
Proxy and Firewall confi gurations may become necessary
when the CommLink IV is connected to a LAN/WAN that is protected
by a commercially available Firewall, Proxy, or NAT enabled router.
Examples of these would include Cisco, NetGear, LinkSys, or WatchGuard Technologies. Also, some ISPs provide IP Address ranges that
are already fi re-walled at the NOC or ISP Head-End. Make sure that
your IT Department or ISP can create a mapped TCP port 39288 on
your fi rewall/proxy to TCP port 39288 on the assigned IP Address of
the CommLink IV.
Only with proper confi guration of the Firewall/Proxy are connections
to the CommLink IV from outside of the local area network going to
be possible. Check that the Firewall/Proxy port is not set to time out
or reset after a specifi ed amount of time when there is no traffi c from
the remote PC.

Troubleshooting Tips
Problems with Prism Software
• Verify that the correct COM port, created by the USB
connection, is selected in the Job Site Window. Verify
COM port number in
<Hardware>, <Device Managers>, <Ports>.
• If using Prism II, verify that CommLink 4 is selected
for Type of CommLink in the Job Sites Window.
• If using Prism, verify that the Baud Rate is set to 19200
in the Job Sites Window.
• Verify that the correct CommLink mode is selected
under Network Confi guration in the Job Sites Window.
• Verify that the USB switch on the back of the
CommLink is set to Normal.
Problems with USB Connection
• Verify that the RX-USB and TX-USB are blinking
when you perform a Search for Units or try to open a
status screen in Prism.

Troubleshooting the COM Port Number
Changing the USB COM Port Number
When the CommLink is fi rst plugged in, it will be assigned a COM port
number to be used for communicating with the Prism software. If the
port number is 10 or greater, it needs to be changed to a value less than
10 to be recognized by Prism.
1. Click <Start>, click <Control Panel>, click
<System>, click the <Hardware> tab, and then click
<Device Manager> to get to the Device
Manager Window.
2. Click on the plus sign next to Ports to see all of the COM

3. Right-click on “USB Serial Port (COM#)” and select
<Properties>. In the Properties Window, select the
<Port Settings> tab.
4. To assign a port number less than 10, click on
<Advanced>. The Advanced Settings Window
will appear.
5. In the COM Port Number drop box, select which COM port
you wish to use. Make sure you select a COM port number
that is not currently in use (you can see the ports in use in
the Device Manager Window). Select a port that is less
than 10.
NOTE: Windows
has ever been installed on your computer. So if there are
no available ports below 10, choose a port number less
than 10 for a device listed that you know you are not
currently using.
6. Once you select the correct COM port number, click <OK>
and close any windows opened in the process of changing
the port number. Make note of this number because you will
need it for your Prism setup.
