CommLink 5 Technical Guide
General Information
CommLink 5 Overview
The OE361-13 CommLink 5 is used to transfer communications
between controllers or local loops on your control system. It can also
be used as an interface for connection of a computer to your system.
The CommLink 5 provides communication with the control system
through any computer that is running Prism 2 software. For remote
communications, an IP Module Kit can be installed for LAN and
Internet connections.
Optional IP Module Kit
The OE415-02 IP Module Kit, when installed and confi gured in
the CommLink 5 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 2 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 2 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 5’s with IP Module Kits installed on individual sites.
Installing CommLink 5 ONLY
When you are using the CommLink 5 in an application without a
computer or IP Module, follow Steps 1 & 2 in the Quick Guide on
page 4.
WARNING: If you are replacing an earlier version of the
CommLink with a CommLink 5, be aware that the polarity
of the terminal block is reversed on the CommLink 5 from all
previous models. You must always confi rm that the polarity is
correct when wiring 24 VAC power to the CommLink power
terminal block or serious damage to the product will result.
NOTE: Please note, the R(+) and T(-) terminals on the
communications terminal block are reversed from all previous
versions of the CommLink.
System Requirements
To program the CommLink 5 to work with Prism 2, you will need:
Standard Items (Required)
• CommLink 5 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
on the PC you are going to use)
• Prism 2 software, version 4.0.3 or later (can be
downloaded from any of our websites)
Optional Items
IP Module Kit that comes with Ethernet RJ-45
•
Crossover CAT 5, 10 ft. long cable for LAN, and Internet
remote communications
• MiniLink, MiniLink PD, or MinkLink PD 5
XP, Vista, 7, or 8 (must be installed

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 5 without utilizing
Prism 2, you need only perform Steps 1 through 3.
Step 1: Set your CommLink’s Loop switch to Multiple or Single.
See Figure 2 on page 6.
Step 2: Set your CommLink’s Baud rate switch to High or Low.
See Figure 3 on page 7.
Step 3: Wire your CommLink to the appropriate controller on your
system, and plug the CommLink into a power supply. See
Figure 1 on page 5.
NOTE: Please note, the R(+) and T(-) terminals on the
communications terminal block are reversed from all previous
versions of the CommLink.
WARNING: If you are replacing an earlier version of the
CommLink with a CommLink 5, be aware that the polarity
of the terminal block is reversed on the CommLink 5 from all
previous models. You must always confi rm that the polarity is
correct when wiring 24 VAC power to the CommLink power
terminal block or serious damage to the product will result.
IMPORTANT NOTES:
First install the USB drivers, then follow the included
CommLink 5 connection and wiring instructions sheet
(Figure 1 on page 5) to connect and confi gure the
CommLink 5.
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 the USB drivers located on the included CD-ROM.
See instructions on page 8. Then attach one end of the USB
cable to the back of your CommLink and the other end into
your computer’s USB port.
Step 5: Install Prism 2 software on your computer. See instructions
on pages 10 & 11.
NOTE: For remote communication, follow the instructions
included in your IP Module Technical Guide.

Connecting the Network
Proxy and Firewall Compatibility
Proxy and Firewall confi gurations may become necessary
when the CommLink 5 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 5.

Troubleshooting Tips
Problems with Prism 2 Software
• Verify that the correct COM port, created by the USB
connection, is selected in the Job Site Window. Verify
COM port number by clicking
<System>, <Hardware>, <Device Managers>,
<Ports>.
• Verify that CommLink 5 is selected for Type of CommLink
in the Job-Sites Window.
• Verify that the correct CommLink mode is selected
under Network Confi guration in the Job-Sites Window.
Problems with USB Connection
• Verify that the TX-USB and RX-USB are blinking
when you perform a Search for Units or try to open a
status screen in Prism 2.
• If the USB LEDs fail to blink, disconnect and
reconnect the USB connection.
• If the problem persists, verify that the USB drivers
have been installed properly.

Problems Viewing Multiple Controllers on a Network
• Make sure that the CommLink’s communication
switch is set to Multiple.
• In Prism 2, make sure that Multiple Loop Confi guration is
selected for Network Confi guration in the Job-Sites

Troubleshooting the COM Port Number
Changing the USB COM Port Number
When the CommLink 5 is fi rst plugged in, it will be assigned a
COM port number to be used for communicating with the Prism 2
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 2.
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
ports.
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
number that is less than 10.
NOTE: Windows
that 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.

will assign a port number to every device
3. Right-click on “USB Serial Port (COM#)” and select
<Properties>. In the Properties Window, select the
<Port Settings> tab.
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 2 setup.
