IP MODULE

General Information

IP Module Overview

The OE415-02 IP Module installs into the CommLink IV or 5
Communications Interface and provides a TCP/IP Port connection
from the WattMaster control system to a building’s Ethernet LAN,
providing communications with the control system through any
computer (with Prism 2 software installed) connected to the LAN
or the Internet (if confi gured for access through your LAN’s
Internet fi rewall).

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 sites.

System Overview

The IP Module is a stand-alone network appliance that connects
to a 10BaseT or 10/100 network connection. The IP Module
will require an IP address on the local network or a routable
IP address provided by an ADSL or cable modem if it is to be
accessed through the Internet. The PC will require a dialup or
Ethernet network connection to the Internet or local network with
routes to the CommLink. Check with your local IT Department
in regards to your network routing needs.

The TCP/IP connection itself is a TCP connection made on a
single port number and is static in nature. Firewall and proxy
servers can be confi gured to allow traffi c to and from this device.
The nature of the data is raw in form and comprised of packets
native to Prism 2 software. The CommLink will respond to ICMP
traffi c (PING) for verifi cation of proper confi guration, but Prism
2 software is required in order to send and receive data to the
CommLink.

System Requirements

To program the IP Module to work with Prism 2, you will need:

• CommLink IV or CommLink 5 with power adapter

• IP Module

• Prism 2 software (can be downloaded from
any of our websites)

• A PC with an Ethernet communications port
(supplied by others)

• Ethernet RJ-45 Crossover CAT 5, 10 ft. long cable
(supplied with the IP Module) and an available
network port to connect the CommLink to your
computer

• Microsoft Windows
installed on the PC you are going to use)

• An IP Address, Subnet Mask, and Gateway Address
for the CommLink’s IP Module. (Ask your Network
Administrator for this information.)

• CommLink 5 ONLY - Baud rate of the control system

that your CommLink 5 is connected to. See Figure 5,
page 9 for further explanation.

Quick Start Guide

Quick Start Guide

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.

Follow the steps below to get your IP Module up and running
in no time.

Step 1: Open your CommLink and snap in your IP

Module. See Figure 1, page 5 for CommLink IV
directions and Figure 2, page 6 for CommLink 5

directions.

Step 5: Connect your CommLink to your PC via

Ethernet cable. See Figures 8 & 9, page 12.

Step 6: Change your PC’s IP address. See Figure 13,

page 13.

Step 7: Change the IP address of your CommLink. See

page 14 for instructions.

Step 8: Set the baud rate for your CommLink in

the Confi guration Settings. See page 14 for

instructions.

IMPORTANT NOTES:

 Follow the included CommLink connection and

wiring instructions sheet (See Figure 6, page 10 or
Figure 7, page 11) to connect and confi gure the

CommLink for an Ethernet connection.

 Make sure you follow the appropriate directions for

your Windows

®

version.

Step 2: Set your CommLink’s communication switch to

Multiple or Single. See Figure 3, page 7 for
CommLink IV directions and Figure 4, page 8

for CommLink 5 directions.

Step 3: Set your CommLink 5’s Baud Rate switch to High

or Low. See Figure 5, page 9.

Step 4:

Wire your CommLink to the appropriate controller

on your system and plug the CommLink into a

power supply. See Figure 6, page 10 for
CommLink IV directions and Figure 7, page 11
for CommLink 5 directions.

 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

If using a hub or switch, connect a standard CAT 5 cable from the
CommLink to the hub or switch. You will also need to connect
your computer to the LAN via standard CAT 5 (by others).

If connecting directly to the CommLink without a hub or switch,
use a crossover CAT 5 Ethernet cable. The LNK-LAN LED will
light up once power is applied, indicating connection to the LAN.

Power up the CommLink by plugging in the power cable. The
CommLink may take up to three minutes to power up completely.
Once the CommLink is powered up, you should notice that the red

Connecting the Network

Proxy and Firewall Compatibility

Proxy and Firewall confi gurations may become necessary

when the CommLink 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.

Only with proper configuration of the Firewall/Proxy are

Troubleshooting Procedures

Ethernet Connection When the device is connected to a

hub, verify that the LINK LED is lit on the CommLink device
and the ACT LED occasionally blinks. The ACT LED indicates
network activity and may be refl ecting other network traffi c.

Ethernet Connection, Routing Verify the route is available

to the CommLink and fi rewalls or proxies are confi gured to pass
TCP network traffi c on port 39288 if necessary. This can be
verifi ed by your Network Administrator.

IP Address Verify that the assigned IP Address is valid for the

local network and that it is not in use by any other device. Try
to PING the CommLink’s IP address to confi rm the address is
correct and responding.

NOTE: Make sure that the CommLink is connected as

shown in Figures 6 or 7 and all installation pro-

cedures have been completed prior to using the
“ping” command.

Prism 2 Software Verify that the IP address is correctly

entered in the connection profi le for the CommLink. Also verify
that the port is left blank in the profi le. This port area specifi es
Comm port settings, not an IP address port.

TCP Port Address The TCP port address 39288 is hard coded

into the EPROM of the CommLink and in Prism 2 software. It
cannot be changed by the end user. The TCP port address needs
to be set in your Prism 2 connection.

To do this, open a DOS session by opening a command prompt:

1. To open a command prompt, click
to <All Programs>, point to <Accessories>,
and then click

2. PING to the IP Address by typing:

ping IP address

Example: ping 192.168.1.25

3. Press <Enter> on the keyboard.

4. If no reply is received, fi rst check your PC’s IP
address and Ethernet connections. If problems
persist, consult your network administrator.
