Technical Guide
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 configure and adjust the setpoints of any controller on the control
system communications loop using Prism 2 graphical front end com-
puter 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 2 software.
System Requirements
To enable the USB-Link 2 to work with Prism 2, 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). Make sure to
install the drivers before connecting the USB-Link 2 to
your computer.
• PC with USB 1.1 or 2.0 port (supplied by others)
• Microsoft®Windows®2000, Vista, 7, 8 & 10
• Prism 2 software version 4.0.4 or later (supplied with USB-
Link 2 but also downloadable from any of our websites)
Networked Systems Only
• CommLink(s) and/or MiniLink(s)

Driver Installation
The internal USB communication port of the USB-Link 2 uses a
specialized driver that must be installed on your Windows PC before
communication to the device can be established.

is running 32-bit or 64-bit Windows. Open the System
information by clicking the <Start> button, clicking
<Control Panel>, and clicking <System>. Under
System, you can view the system type. Based on what
type of system you have, you will choose 32_Bit.exe or
64_Bit.exe from the list of files shown in Step 10.
2. Insert the USB Drivers CD-ROM into your CD-ROM
drive or download the USB Drivers file from www.
orioncontrols.com/a/software/. If using the CD-ROM,
go to Step 7. If downloading the file, you will need to
scroll down the page until you find “USB Drivers For
All Products” to download the driver files.
3. Right click on “Click Here.” Then click <Save Link
As> or <Save Target As> and select Desktop as the
destination.
4. Go to the “USB-DRIVERS-ALL.exe” file on your desk-
top. Double-click on this file and choose “Run” from the
options list. The following window will appear:
5. Select <Unzip> and the file will be unzipped to the

6. Next, go to the C:\Temp\WM-USB-Drivers folder and
now go to Step 9.
7. Click your <Start> button and then click, <Computer>.
8. Double-click on your CD-ROM drive. Open the Media
Files Folder.
9. Double-click the folder “USBLink NewSS0073”.
10. The following list of files will display. Choose 32_Bit.
exe or 64_Bit.exe based on what type of system you
determined you have in Step 1.
11. In the window that pops up, shown below, click <Next>
and the installation program will walk you through the
rest of the steps.
12. When successful installation has occurred, connect the
USB cable between the PC and the USB-Link 2. The
PC will automatically recognize the device and a COM
port will be assigned. Follow the procedures on page 7 to
verify the Comm Port.
