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 can be con-
nected for dial-up connections.
Optional IP Module Kit
The OE415-02 IP Module Kit, when installed and congured in
the CommLink IV communication interface, provides TCP/IP
Internet and/or intranet connection for Ethernet networked com-
puter 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 soft-
ware, you are able to monitor and congure your controllers
without a modem or a direct connection from a PC. Utilizing
existing routers, proxies, or rewalls allows a PC running Prism
to connect to a controller in a remote accessible location or build-
ing. Several IP connection proles can be created to facilitate
monitoring several CommLink IVs with IP Module Kits installed
on individual sites.
Optional Remote Link
The OE-419-06 Remote Link 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. Connection is made by dialing the telephone number
of the job site where the Remote Link is located. Using another
Remote Link modem connected to a computer at a remote loca-
tion, the control system can be monitored and controlled using
the Prism computer front end software package.
Installing CommLink IV ONLY
When you are using the CommLink IV in an application without
a computer, Remote Link, or IP Link Module, wire the RS-485
loop terminal to a MiniLink, MiniLink PD, or other controller on
your controls loop as required by your specic system.
Connect the power pack to a 110 volt wall outlet and connect
its wires to the power terminal block on the CommLink IV. If
desired, a 24 vac transformer rated at 12 VA minimum may be
used instead of the supplied power pack. Use 18 gauge minimum
2 conductor wire between the transformer and CommLink IV
terminals. Set the dip switch on the CommLink IV as shown in
Figure 2.
System Requirements
To program the CommLink IV to work with Prism, you will
need:
Standard Items (Required)
• CommLink IV with power adapter
• A PC with an Ethernet communications port or USB
port (supplied by others)
• Microsoft Windows 98, NT, 2000, XP, or Vista
(must be installed on the PC you are going to use)
• Prism software CD (ordered separately from
WattMaster)
Optional Items
• CommLink IP Module that comes with
Ethernet RJ-45 Crossover CAT 5, 10 ft. long cable for
LAN, and Internet remote communications
• Remote Link that comes with connection
cables for dial up remote communications

Changing the USB Serial COM Port
Number
When the CommLink IV is 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 higher than 9, it needs to be
changed to a value less than 9 to be recognized by Prism. Follow
the steps below to do this.
1. Click <Start>, click <Control Panel>, click
<System>, and then 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
common ports.
3. Right-click on “USB Serial Port (COM#)” and select
<Properties>. In the Properties Window, select the
<Port Settings> tab.
4. Change the Bits per Second (Baud Rate) to 19200.
Then click on <Advanced>.
5. In the COM Port Number drop box, select which
COMM Port you wish to use. Be sure you do not
select a COM number that is already in use. Select a
port that is less than 10.
6. Once you select the correct COM Port Number, click
<OK> and close any windows opened in the process
of changing the port number.

This LED only ashes when your CommLink is connected
to a computer and data is sent from Prism to the CommLink
via USB.
TX-CPU - Indicates transmitted data status. This LED only
ashes when your CommLink is connected to a computer
and data is sent to Prism from the CommLink using USB or
Ethernet.
RX-CPU - Indicates received data status. This LED only
ashes when your CommLink is connected to a computer
and data is sent from Prism to the CommLink using USB or

Connecting the Network
Figure 4: Example Network Diagram of a Firewall or Proxy Conguration
Proxy and Firewall Compatibility
Proxy and Firewall con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 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 rewall/proxy to TCP port
39288 on the assigned IP Address of the CommLink IV.
Only with proper conguration of the Firewall/Proxy are connec-
tions 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 specied amount of time passes
unless there is no trafc from the remote PC.

Troubleshooting
Troubleshooting Procedures
Prism Software Verify that the correct Comm Port, created
by the USB connection, is selected in the Job Site List & Connec-
tion Method Window. Verify Comm Port # in <Control Panel>,
<System>,<Hardware>, <Device Managers>, <Ports>.
USB Connection Verify that the RX-USB and TX-USB are
blinking occasionally on the CommLink IV. If no LEDs are blink-
ing, disconnect and reconnect the USB connection. If the problem
persists, check that drivers are installed properly.
NOTE: WattMaster Controls Technical Support cannot
troubleshoot internal PC and/or Windows-based
operating system problems.
