USB-Link 2 Overview
The USB-Link 2 (OE366) is a portable device that is used as an interface to connect your computer to WattMaster controllers without the need for a CommLink.
The USB-Link 2 provides a direct link to enable you to view the status and confi gure and adjust the setpoints of any controller on the control system communications loop using Prism II graphical front end computer software.
The USB-Link 2 is small in size and is powered by the USB port of the computer it is plugged into, making it completely portable and allowing connection to the system from any controller.
The USB-Link 2 is supplied with a USB cable, a mini-DIN male communication cable, and two mini-DIN to terminal adapters. The communication cable allows you to walk up to any controller that has a communication socket and plug in the USB-Link 2 to gain access to the system. The adapters are used for boards that do not have a female mini-DIN plug connection.
CAUTION: The USB-Link 2 will not work with Prism software.
It will only work with Prism II software.
System Requirements
To enable the USB-Link 2 to work with Prism II, you will need:
• USB-Link 2 with USB cable, mini-DIN male communication cable, and adapters for terminal and modular connections (cables and adapters provided)
• USB drivers on CD-ROM (supplied with USB-Link 2 but also downloadable from any of our websites)
• PC with USB 1.1 or 2.0 port (supplied by others)
• Microsoft ® Windows ® XP, Vista, or 7
• Prism II software (supplied with USB-Link 2 but also downloadable from any of our websites)
Networked Systems Only
• CommLink(s) with software v3.15 or later and/or Mini
Link(s) with software v3.14 or later.
Please note: If these devices contain earlier software versions, you will need to order updated EPROMs from
WattMaster. See Troubleshooting on page 13 for further
instructions.

Stand Alone - No MiniLink or CommLink - The slide switch on the USB-Link 2 should be set to “Stand Alone” when you are trying to talk to a stand alone controller or multiple controllers on a loop without a CommLink or a MiniLink wired to the communications loop.
Network - MiniLink or CommLink connection - The slide switch on the USB-Link 2 should be set to “Network” any time there is a CommLink or MiniLink wired to the communications loop.
USB-Link 2 LED Descriptions
COMM Indicates communication activity between the USB-Link
2 and the controller(s) that the USB-Link 2 is connected to.
When this LED is fl ashing, data is being exchanged.
USB TX & USB RX Indicates communication activity between the USB-Link 2 and the computer that the USB-Link 2 is connected to. The LEDs will fl ash only when data is sent from Prism
II to the USB-Link via USB.

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

Troubleshooting
Problems with RS-485 Wiring
• Make sure T connects to T, R to R, and Shld to Shld if
multiple boards are wired together on a loop.
• Make sure that the USB-Link 2 mini-DIN communication
cable is plugged into a controller or wired to the local
side of the loop.
Problems Viewing Controllers on a Network
• Make sure that in Prism II, USB Link Network is
selected under Network Confi guration in the Job Sites
Window.
• Make sure that EPROM chips in CommLink II and III
are version 3.15 or later and in MiniLinks are version
3.14 or later.

Troubleshooting the COM Port Number
4. To assign a port number less than 10, click on
<Advanced> . The Advanced Settings Window will appear.
Changing the USB COM Port Number
When the USB-Link 2 is fi rst plugged in, it will be assigned a COM port number to be used for communicating with the Prism II 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 II.
1. Click <Start> , click <Control Panel> , click
<System> , click the
<Device Manager>
<Hardware> tab, and then click
to get to the Device
Manager Window.
2. Click on the plus sign next to Ports to see all of the COM ports.
3. Right-click on “USB Serial Port (COM#)” and select
<Properties> . In the Properties Window, select the
<Port Settings> tab.
5. In the COM Port Number drop down 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 ® will assign a port number to every device 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.
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.

Troubleshooting EPROM Software
Verifying CommLink II, CommLink III, and MiniLink EPROM Software Versions
In order to view controllers with the USB-Link 2 on a networked system, the CommLink II and III must have version 3.15 software or later installed and the MiniLink must have version 3.14 software or later installed. Please follow the directions to determine the current software version.
NOTE:
If you purchased your CommLink II, III, or MiniLink
after January 1, 2007, there is no reason to check the
software version nor is it necessary to check the soft-
ware version of a CommLink IV or 5.
