Modes of Operation

There are two modes in which the QD2040 can operate.

One method is stand-alone server mode utilizing the

embedded Ubiquity software. The second method is

by directly communicating to a centrally hosted Ubiquity

server. In stand-alone mode the QD2040 functions

as the server to the controller network and can be

accessed via the Internet, through a local or wide area

network (LAN or WAN), or by dial-in modem connection.

All access methods utilize a simple web browser

interface. The QD2040 may also be accessed via direct

connection from a laptop using the included CAT 5

Crossover Patch Cable.

NOTE: Despite its appearance this is a unique cable

designed especially for direct connections between

two computers. Other ethernet cables will not work.

The other method of operation for the QD2040

is to communicate directly to a centrally hosted

Ubiquity server by connecting to the Internet or by

connecting to a local or wide area network (LAN

or WAN). By connecting to a centrally hosted server,

the advantages of multi-site enterprise functionality is

achieved. Enterprise features include: multi-site global

programming, global scheduling, global alarming and

enterprise data aggregation. In addition, some local

control functions are still performed by the QD2040 (ie.

Loop control, energy curtailment, outdoor air sharing,

etc.)

Initial Configuration

The QD2040 comes from the factory with a default

mode of Stand-alone / Dial-In. The unit also comes

with a special setup mode enabled. This setup mode

is called 'Setup DHCP Server' and in this mode the

QD2040 acts as a DHCP server which allows capability

of setting up the QD2040 by simply connecting to it

with a laptop or desktop PC. Caution: The QD2040

comes programmed with a default setup mode and

functions as a DHCP server. When setting up the

QD2040, be sure the QD2040 is not connected to

another DHCP enabled network.

Before connecting the QD2040 to a LAN or WAN, you

must first configure the unit for operation. To configure

the QD2040, connect the QD2040 to a PC or laptop that

is NOT connected to a network during the configuration

process. Make this connection from the ethernet port

of the QD2040 to the ethernet port of the PC using

the CAT 5 crossover ethernet cable included with the

QD2040. After you have made the connection from the

QD2040 to the PC, power up the QD2040 and wait 3

minutes for the QD2040 to completely boot up. You

then need to reboot your laptop or PC to allow it to be

assigned an IP address from the QD2040. Open the

web browser program (Internet Explorer v5.0 or higher

is the recommended browser). In the browser address

space, type in IP address http://192.168.1.1 and press

enter to navigate to the QD2040 login page. Enter

username: admin and password: password to reach

the QD2040 Ubiquity home page. From this page

you can configure the operation mode of the QD2040

(See Setup & Programming section) by navigating to

the following links at the top of the home page Admin

> QD2040 Setup. You can now change parameters of

the QD2040 or link to the control addressing page to

address controllers, that do not have displays, prior

to installation. (See Control Addressing section) After

QD2040 configuration is complete, disconnect PC from

the QD2040. The QD2040 is now ready for installation.
