General Information

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 2 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 2 software.
